What are "Carbon Emissions"?

"Carbon Emissions" are technically and more accurately called "Carbon Dioxide Emissions." 

In today's fast-paced news world and need to get information out quickly, the term Carbon Dioxide Emissions, has been abbreviated to "Carbon Emissions."

According to the EPA, Carbon Dioxide Emissions, or "Carbon Emissions" or simply "CO2," are generated in a number of ways. Carbon Dioxide Emissions are produced naturally through the carbon cycle and through human activities like the burning of fossil fuels.

Natural sources of CO2 occur within the carbon cycle where billions of tons of atmospheric CO2 are removed from the atmosphere by oceans and growing plants, also known as ‘sinks,’ and are emitted back into the atmosphere annually through natural processes also known as ‘sources.’ When in balance, the total carbon dioxide emissions and removals from the entire carbon cycle are roughly equal.

Since the Industrial Revolution in the 1700’s, human activities, such as the burning of oil, coal and gas, and deforestation, have increased CO2 concentrations in the atmosphere. In 2005, global atmospheric concentrations of CO2 were 35% higher than they were before the Industrial Revolution.

Carbon Dioxide Emissions are responsible for about 80% of the problems related to Greenhouse Gas Emissions. 

Carbon Dioxide Emissions and carbon dioxide are one of the six chemicals

• methane and Biomethane

• nitrous oxide

• hydrofluorocarbons 

• perfluorocarbons 

• sulfur hexafluoride

and all six chemicals are planned to be significantly reduced via the global agreements under the Kyoto Protocol and new legislation in the U.S. under the pending "Cap and Trade" regulations in an effort to prevent climate change. 

What are Greenhouse Gas Emissions?

Greenhouse Gas Emissions are those greenhouse gases that allow sunlight to enter the atmosphere freely and contribute to the greenhouse effect, which many believe is the cause of global warming. There are natural and man-made greenhouse gas emissions.  The primary greenhouse gases thought to be major contributors to global warming are; carbon dioxide emissions (CO2), methane emissions (CH 4) and nitrogen oxides (N2O). 

The primary sources of greenhouse gas emissions from manmade sources include; fossil-fueled power plants such as natural gas power plants and coal fired power plants. Other sources of greenhouse gas emissions linked to manmade causes include  internal combustion engines (fueled by gasoline and petroleum diesel) and deforestation.

Many people don't realize that as much as 25% of  per cent of the carbon dioxide emissions are naturally absorbed by the ocean and another 25% of the carbon dioxide emissions are absorbed by our biosphere, such as trees, plants, soil, etc.  This leaves about 50% of the carbon dioxide emissions that are not absorbed and remaining in our atmosphere. As previously stated, carbon dioxide emissions are linked primarily to the burning of fossil fuels (power plants, cars, trucks, etc.) and deforestation.

Greenhouse gas emissions have been on the increase ever since the dawn of the industrial revolution.

What Are Greenhouse Gases?

Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface roughly constant.

Many gases exhibit these “greenhouse” properties. Some of them occur in nature (water vapor, carbon dioxide, methane, and nitrous oxide), while others are exclusively human-made (like gases used for aerosols).

How Can We Decrease Greenhouse Gas Emissions?

Greenhouse gas emissions can be reduced by switching from fossil fuels to renewable energy technologies, such as solar energy systems, and upgrading brown buildings to Net Zero Energy Buildings.

Why Are Atmospheric Levels of Greenhouse Gas Emissions Increasing?

Levels of several important greenhouse gases have increased by about 25 percent since large-scale industrialization began around 150 years ago (Figure 1). During the past 20 years, about three-quarters of human-made carbon dioxide emissions were from burning fossil fuels.

Figure 1. Trends in Atmospheric Concentrations and Anthropogenic Emissions of Carbon Dioxide

Concentrations of carbon dioxide in the atmosphere are naturally regulated by numerous processes collectively known as the “carbon cycle” (Figure 2). The movement (“flux”) of carbon between the atmosphere and the land and oceans is dominated by natural processes, such as plant photosynthesis. While these natural processes can absorb some of the net 6.1 billion metric tons of anthropogenic carbon dioxide emissions produced each year (measured in carbon equivalent terms), an estimated 3.2 billion metric tons is added to the atmosphere annually. The Earth’s positive imbalance between emissions and absorption results in the continuing growth in greenhouse gases in the atmosphere.

Figure 2. Global Carbon Cycle (Billion Metric Tons Carbon)

What Effect Do Greenhouse Gas Emissions Have on Climate Change?

Given the natural variability of the Earth’s climate, it is difficult to determine the extent of change that humans cause. In computer-based models, rising concentrations of greenhouse gases generally produce an increase in the average temperature of the Earth. Rising temperatures may, in turn, produce changes in weather, sea levels, and land use patterns, commonly referred to as “climate change.”

Assessments generally suggest that the Earth’s climate has warmed over the past century and that human activity affecting the atmosphere is likely an important driving factor. A National Research Council study dated May 2001 stated, “Greenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and sub-surface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.”

However, there is uncertainty in how the climate system varies naturally and reacts to emissions of greenhouse gases. Making progress in reducing uncertainties in projections of future climate will require better awareness and understanding of the buildup of greenhouse gases in the atmosphere and the behavior of the climate system.

What Are the Sources of Greenhouse Gas Emissions?

In the U.S., our greenhouse gas emissions come mostly from energy use. These are driven largely by economic growth, fuel used for electricity generation, and weather patterns affecting heating and cooling needs. Energy-related carbon dioxide emissions, resulting from petroleum and natural gas, represent 82 percent of total U.S. human-made greenhouse gas emissions (Figure 3). The connection between energy use and carbon dioxide emissions is explored in the box on the reverse side (Figure 4).

Figure 3. U.S. Anthropogenic Greenhouse Gas Emissions by Gas, 2001 (Million Metric Tons of Carbon Equivalent)  

Figure 4. U.S. Primary Energy Consumption and Carbon Dioxide Emissions, 2001

Another greenhouse gas, Biomethane, comes from landfills, coal mines, oil and gas operations, and agriculture; it represents 9 percent of total emissions. Nitrogen oxides (5 percent of total emissions), meanwhile, is emitted from burning fossil fuels and through the use of certain fertilizers and industrial processes. Human-made gases (2 percent of total emissions) are released as byproducts of industrial processes and through leakage.

What Is the Prospect for Future Carbon Dioxide Emissions?

World carbon dioxide emissions are expected to increase by 1.9 percent annually between 2001 and 2025 (Figure 5). Much of the increase in these emissions is expected to occur in the developing world where emerging economies, such as China and India, fuel economic development with fossil energy. Developing countries’ emissions are expected to grow above the world average at 2.7 percent annually between 2001 and 2025; and surpass emissions of industrialized countries near 2018.

Figure 5. World Carbon Dioxide Emissions by Region, 2001-2025
(Million Metric Tons of Carbon Equivalent)

The U.S. produces about 25 percent of global carbon dioxide emissions from burning fossil fuels; primarily because our economy is the largest in the world and we meet 85 percent of our energy needs through burning fossil fuels. The U.S. is projected to lower its carbon intensity by 25 percent from 2001 to 2025, and remain below the world average (Figure 6).

Figure 6. Carbon Intensity by Region, 2001-2025
(Metric Tons of Carbon Equivalent per Million $1997)

Energy Production and Carbon Dioxide Emissions

For over one hundred years, energy and power production have been generated around the world through the burning of fossil fuels, including;  fuel oil, coal, diesel, and natural gas.  Over the past decade, environmental science and research has discovered and linked global warming, and global climate change to the carbon dioxide emissions from the combustion of fossil fuels.  This has placed an increased need to reduce energy consumption and discover more environmentally friendly fuel sources.

EPA Moves Closer To Regulating Carbon Dioxide Emissions 
and All Other Leading Greenhouse Gas Emissions

April 18, 2009

WASHINGTON — In a major reversal of years of government policy regarding Greenhouse Gas Emissions, the Environmental Protection Agency today proposed regulating Greenhouse Gas Emissions to combat and reverse global warming and climate change.

"In both magnitude and probability, climate change is an enormous problem" said E.P.A's Administrator Lisa Jackson in their 130 page report on Greenhouse Gas Emissions. "This finding confirms that greenhouse gas pollution is a serious problem now and for future generations. Fortunately, it follows [US President Barack H. Obama's] call for a low-carbon economy and strong leadership in Congress on clean energy and climate legislation. Greenhouse Gas Emissions and greenhouse gas pollution problems have a solution, one that will create millions of green jobs and end our country's dependence on foreign oil," according to Jackson. 

Jackson said this report found that projected levels of Greenhouse Gas Emissions "endanger the public health and welfare of current and future generations."  The finding came two years after the Supreme Court ruled the EPA had the authority to regulate Greenhouse Gas Emissions under the Clean Air Act.

"Renewable Energy Technologies such as; Anaerobic Digesters, Biomethane, Concentrating Solar Power, Geothermal Power Plants are "carbon neutral energy" technologies, and generate no new Greenhouse Gas Emissions.  Power generated from Biomass Gasification power plants, are "carbon negative energy" solutions which actually remove carbon dioxide emissions from the atmosphere, according to the Founder and Chairman of the Institute for Climate Solutions, and the Renewable Energy Institute's Mont Goodell.

What is a "Parabolic Trough" or a "Parabolic Trough Collector"?

A parabolic trough or a parabolic trough collector, is one of the components that make up a Parabolic Trough Power Plant, which is a type of "Concentrating Solar Power" plant.  

Parabolic Troughs are, in essence, curved mirrors designed to reflect the energy from the sunlight, onto a "Dewar Tube" that  run the length of the parabolic trough's focal point.  Parabolic Troughs are typically constructed with either a coated silver or polished aluminum. 

Parabolic Troughs are aligned on a north-south basis and they track or rotate throughout the day to follow the sun in order to keep the maximum amount of the sun's available energy concentrated on them.

Inside the Dewar Tube is a "heat transfer fluid" that absorbs the heat energy from the sun, which is then pumped from the Dewar Tube to a Heat Recovery Steam Generator, where the heat energy is converted into steam, which then drives one or more steam turbines, which is connected to a synchronous generator, which then generates electricity and is sent to the electric grid. 

The temperature of the heat transfer fluid quickly reaches 750 degrees as the sun's energy is captured by the Parabolic Troughs.  The overall process is very economical and thermal efficiency ranges from about 60% to as high as 80%.

What is Concentrating Solar Power?

Concentrating solar power plants produce electric power by converting the sun's energy into high-temperature heat using various mirror configurations. The heat is then channeled through a conventional generator. The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts heat energy to electricity.

Concentrating solar power systems can be sized for village power (10 kilowatts) or grid-connected applications (up to 100 megawatts). Some systems use thermal storage during cloudy periods or at night. Others can be combined with natural gas and the resulting hybrid power plants provide high-value, dispatchable power. These attributes, along with world record solar-to-electric conversion efficiencies, make concentrating solar power an attractive renewable energy option in the Southwest and other sunbelt regions worldwide.

Why Concentrating Solar Power is one of the Few "Superior" Renewable Energy Technologies

Concentrating solar power plants use the high annual solar irradiance of the geographic location to generate "carbon free energy" and "pollution free power."  

For generating power after the sun sets, many owners/developer of concentrating solar power plants are now installing "Molten Salt Storage" systems that reserves enough energy to allow for electricity generation throughout the nighttime period.  

Steam turbines and gas turbines powered by coal, uranium, oil and natural gas are the fuels used today for generating power and electric grid stability.  These fuels provide both base-load and peak power.  However, these same steam turbines can also be powered by the high temperature
heat from concentrating solar power plants. 

Concentrating solar power plants in the 30 MW - 200 MW range are now operating successfully in locations from California to Europe.  Nearly every day now, new concentrating solar power plants are being planned for construction.  The concentrating solar collectors are very efficient and they also completely replace the fossil fuels that were used in traditional power plants.  Today's concentrating solar power plants generate the heat needed to generate electricity at a cost equivalent to $50 - $60 per barrel of oil (equivalent).  This cost is expected be slashed by 50% to below $25 - $30 per barrel in the next 10 years.  

Just like conventional fossil-fueled power plants, concentrating solar power plants generate  base-load and peaking power electricity.  

Just like fossil fuel fired conventional power plants, concentrating solar power plants have an availability that is close to 100 %, but without the carbon emissions, carbon dioxide emissions, hazardous air pollutants, nitrogen oxides, volatile organic compounds and greenhouse gas emissions that fossil fuel power plants emit.

A concentrating solar power plant with a molten salt storage facility for full load operation during the nighttime period is currently being built in the Spanish Sierra Nevada near Guadix. This concentrating solar power plant will generate 50 MW of power.

Another feature that distinguishes concentrating solar power plants is the opportunity for combined generation of heat and power - a technology that is called "Integrated Solar Combined Cycle" which achieves the highest possible efficiencies for energy conversion. In addition to power generation, such plants can provide steam for absorption chillers and/or adsorption chillers, industrial process heat or thermal ocean water desalination. A design study for such a plant was completed in 2006.  This plant is scheduled to be commissioned in early 2009. This Integrated Solar Combined Cycle will provide 10 MW of power, 40 MW of district cooling and 10,000 cubic meters per day of desalted water for a large hotel in Jordan.

 

Concentrating Solar Power www.ConcentratingSolarPower.com This solar thermal power plant located in the Mojave Desert in Kramer Junction, California, is one of nine Concentrating Solar Power plants built in the 1980s. During operation, oil in the receiver tubes collects the concentrated solar energy as heat and is pumped to a power block (in background) for conversion to steam, which then turns steam turbines for generating electricity.   Solar Dish Engine see:  www.SolarDishEngine.com  for more information This solar dish engine is an electric generator that "burns" sunlight instead of gas or coal to produce electricity. The solar dish engine (above) is a solar "concentrator" and is the primary solar component of the system.  The solar dish engine collects sunlight and concentrates the sunlight  on a small area. A thermal receiver absorbs the concentrated beam of solar energy, converts it to heat, and transfers the heat to the engine/generator. The U.S. Department of Energy (DOE) is actively involved in the research of Concentrating Solar Power (CSP). This research and development (R&D) focuses on three types of concentrating solar power  technologies: trough systems, dish/engine systems, and power towers. These technologies are used in concentrating solar power plants that use different kinds of mirror configurations to convert the sun's energy into high-temperature heat. The heat energy is then used to generate electricity in a steam generator. Concentrating solar power plant's relatively low cost and ability to deliver power during periods of peak demand - when and where we need it - means that concentrating solar power can be a major contributor to the nation's future needs for distributed sources of "carbon free energy" and "pollution free power." DOE's Solar Energy Technologies Program works in concentrating solar power  R&D to provide clean, reliable, affordable solar thermal electricity for the nation. The program's goal is to ensure that solar thermal technologies like concentrating solar power make an important contribution to the world's growing need for "carbon free energy" and "pollution free power."

Technology Overview

Concentrating solar power plants produce electric power by converting the sun's energy into high-temperature heat using various mirror configurations. The heat is then channeled through a conventional generator. The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts heat energy to electricity.

Concentrating solar power systems can be sized for village power (10 kilowatts) or grid-connected applications (up to 100 megawatts). Some systems use thermal storage during cloudy periods or at night. Others can be combined with natural gas and the resulting hybrid power plants provide high-value, dispatchable power. These attributes, along with world record solar-to-electric conversion efficiencies, make concentrating solar power an attractive renewable energy option in the Southwest and other sunbelt regions worldwide.

The Solar Resource

The solar resource for generating power from concentrating solar power systems is plentiful. For instance, enough electric power for the entire country could be generated by covering about 9 percent of Nevada—a plot of land 100 miles on a side—with parabolic trough systems.

The solar resources for generating power from concentrating solar power systems is plentiful. For instance, enough electric power for the entire country could be generated by covering about 9 percent of Nevada – a plot of land 100 miles on a side – with parabolic trough systems.

The amount of power generated by a concentrating solar power plant depends on the amount of direct sunlight. Like concentrating photovoltaic concentrators, these technologies use only direct-beam sunlight, rather than diffuse solar radiation.

The southwestern United States potentially offers the best development opportunity for concentrating solar power technologies in the world. There is a strong correlation between electric power demand and the solar resource due largely to air conditioning loads in the region. In fact, the Solar Electric Generating System plants operate for nearly 100% of the on-peak hours of Southern California Edison.

How Does It Work?

There are three kinds of concentrating solar power systems—troughs, dish/engines, and power towers—that are classified by how they collect solar energy.

Parabolic Trough systems:

The sun's energy is concentrated by parabolic (curved) trough-shaped reflectors onto a receiver pipe running along the inside of the curved surface. This energy heats an oil that flows through the pipe.  The heat energy is then pumped to a location where the heat energy is converted to steam and the stem then generates electricity through one or more steam turbines. 

A collector field comprises many troughs in parallel rows aligned on a north-south axis. This configuration enables the single-axis troughs to track the sun from east to west during the day to ensure that the sun is continuously focused on the receiver pipes. Individual Parabolic Trough systems currently can generate about 80 megawatts of electricity.

Parabolic Trough designs can incorporate thermal storage - setting aside the heat transfer fluid in its hot phase - allowing for electricity generation several hours into the evening. Currently, all parabolic trough plants are "hybrids," meaning they use fossil fuel to supplement the solar output during periods of low solar radiation. Typically a natural gas-fired heat or a gas steam boiler/reheater is used; troughs also can be integrated with existing coal-fired plants.

Solar Power Tower systems:

What is a Solar Power Tower and How Does it Work?

A power tower converts sunshine into clean electricity for the world’s electricity grids. The technology utilizes many large, sun-tracking mirrors (heliostats) to focus sunlight on a receiver at the top of a tower. A heat transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine-generator to produce electricity. Early power towers (such as the Solar One plant) utilized steam as the heat transfer fluid; current designs (including Solar Two, pictured) utilize molten nitrate salt because of its superior heat transfer and energy storage capabilities. Individual commercial plants will be sized to produce anywhere from 50 to 200 MW of electricity.

What are the Benefits of Solar Power Towers?

Solar power towers offer large-scale, distributed solutions to our nation’s energy needs, particularly for peaking power. Like all solar technologies, they are fueled by sunshine and do not release greenhouse gases. They are unique among solar electric technologies in their ability to efficiently store solar energy and dispatch electricity to the grid when needed — even at night or during cloudy weather. A single 100-megawatt power tower with 12 hours of storage needs only 1000 acres of otherwise non-productive land to supply enough electricity for 50,000 homes. Throughout the sunny Southwest, millions of acres are available with solar resources that could easily produce solar power at the scale of hydropower in the Northwest U. S.

What is the Status of Power Tower Technology?

Power towers enjoy the benefits of two successful, large-scale demonstration plants. The 10-MW Solar One plant near Barstow, CA, demonstrated the viability of power towers, producing over 38 million kilowatt-hours of electricity during its operation from 1982 to 1988. The Solar Two plant was a retrofit of Solar One to demonstrate the advantages of molten salt for heat transfer and thermal storage. Utilizing its highly efficient molten-salt energy storage system, Solar Two successfully demonstrated efficient collection of solar energy and dispatch of electricity, including the ability to routinely produce electricity during cloudy weather and at night. In one demonstration, it delivered power to the grid 24 hours per day for nearly 7 straight days before cloudy weather interrupted operation.

The successful conclusion of Solar Two sparked worldwide interest in power towers. As Solar Two completed operations, an international consortium, led by the U. S. (with technical support from Sandia National Laboratories), formed to pursue power tower plants worldwide, especially in Spain (where special solar premiums make the technology cost-effective), but also in Egypt, Morocco, and Italy. Their first commercial power tower plant is planned to be four times the size of Solar Two (about 40 MW equivalent, utilizing storage to power a 15MW turbine up to 24 hours per day).

This industry is also actively pursuing opportunities to build a similar plant in our desert Southwest, where a 30 to 50 MW plant would take advantage of the Spanish design and production capacity to reduce costs, while providing much needed peaking capacity for the Western grid. The first such plant would cost in the range of $100M and produce power for about 15¢/kWh. While still somewhat higher in cost than conventional technologies in the peaking market, the cost differential could be made up with modest green power subsidies and political support, jump-starting this technology on a path to 7¢/kWh power with the economies of scale and engineering improvements of the first few plants. It would, at that point, provide clean power as economically as more conventional technologies.

The Solar Dish Engine project will evaluate the performance of the “critical” parts of the Stirling engine and develop the next-generation of the 25 kW Solar Dish Engine System.

Solar Dish Engines

What is a Solar Dish Engine?

A Solar Dish Engine is an electric generator that “burns” sunlight instead of gas or coal to produce electricity. The major parts of a system are the solar concentrator and the power conversion unit. Descriptions of these subsystems and how they operate are presented below.

The dish, which is more specifically referred to as a concentrator, is the primary solar component of the system. It collects the solar energy coming directly from the sun (the solar energy that causes you to cast a shadow) and concentrates or focuses it on a small area. The resultant solar beam has all of the power of the sunlight hitting the dish but is concentrated in a small area so that it can be more efficiently used. Glass mirrors reflect ~92% of the sunlight that hits them, are relatively inexpensive, can be cleaned, and last a long time in the outdoor environment, making them an excellent choice for the reflective surface of a solar concentrator. The dish structure must track the sun continuously to reflect the beam into the thermal receiver.

The power conversion unit includes the thermal receiver and the engine/generator. The thermal receiver is the interface between the dish and the engine/generator. It absorbs the concentrated beam of solar energy, converts it to heat, and transfers the heat to the engine/generator. A thermal receiver can be a bank of tubes with a cooling fluid, usually hydrogen or helium, which is the heat transfer medium and also the working fluid for an engine. Alternate thermal receivers are heat pipes wherein the boiling and condensing of an intermediate fluid is used to transfer the heat to the engine.

The engine/generator system is the subsystem that takes the heat from the thermal receiver and uses it to produce electricity. The most common type of heat engine used in dish-engine systems is the Stirling engine. A Stirling engine uses heat provided from an external source (like the sun) to move pistons and make mechanical power, similar to the internal combustion engine in your car. The mechanical work, in the form of the rotation of the engine’s crankshaft, is used to drive a generator and produce electrical power.

In addition to the Stirling engine, concentrating photovoltaic technologies are also being evaluated as possible future power conversion unit technologies. A photovoltaic conversion system is not actually an engine, but a semi-conductor array, in which the sunlight is directly converted into electricity.

What are the markets for Solar Dish-Engines?

Solar dish engines are being developed for use in emerging global markets for distributed generation, green power, remote power, and grid-connected applications. Individual units, ranging in size from 9 to 25 kilowatts, can operate independent of power grids in remote sunny locations to pump water or to provide electricity for people living in remote areas. Largely because of their high efficiency and “conventional” construction, the cost of dish-engine systems is expected to compete in distributed markets.

Opportunities are emerging for the deployment of dish-engine systems in the Southwest U.S. Many states are adopting green power requirements in the form of “portfolio standards” and renewable energy mandates. While the potential markets in the U.S. are large, the size of developing worldwide markets is immense. The International Energy Agency projects an increased demand for electrical power worldwide more than doubling installed capacity. More than half of this is in developing countries and a large part is in areas with good solar resources, limited fossil fuel supplies, and no power distribution network. The potential payoff for dish-engine system developers is the opening of these immense global markets for the export of power generation systems.

 

Experience gained with Solar Two has established a foundation which will lead to the first commercial Concentrating Photovoltaic Power Plant

Business and Market Opportunities

With one of the best direct normal insolation resources anywhere on earth, the southwestern states are poised to reap large and as yet largely uncaptured economic benefits from this important natural resource. California, Nevada, Arizona, and New Mexico are each exploring policies that will nurture the development Concentrated Solar Power Technologies..

In addition to the concentrating solar power projects under way in this country, a number of projects are being developed in India, Egypt, Morocco, and Mexico. In addition, independent power producers are in the early stages of design and development for potential parabolic trough power projects in Greece (Crete) and Spain. Given successful deployment of one or more of these initial markets, additional project opportunities are expected in these and other regions.

One key competitive advantage of concentrating solar energy systems is their close resemblance to most of the power plants operated by the nation's power industry. Concentrating solar power technologies utilize many of the same technologies and equipment used by conventional central station power plants, simply substituting the concentrated power of the sun for the combustion of fossil fuels to provide the energy for conversion into electricity. This "evolutionary" aspect—as distinguished from "revolutionary" or "disruptive"—results in easy integration into today's central station–based electric utility grid. It also makes concentrating solar power technologies the most cost-effective solar option for the production of large-scale electricity generation.

Analysts predict the opening of specialized niche markets in this country for the solar power industry over the next 5 to 10 years. The U.S. Department of Energy estimates that by 2005 there will be as much as 500 megawatts of concentrating solar power capacity installed worldwide.

What Does It Cost?

Concentrating solar power technologies currently offer the lowest-cost solar electricity for large-scale power generation (10 megawatt-electric and above). Current technologies cost $2–$3 per watt. This results in a cost of solar power of 9¢–12¢ per kilowatt-hour. New innovative hybrid systems that combine large concentrating solar power plants with conventional natural gas combined cycle or coal plants can reduce costs to $1.5 per watt and drive the cost of solar power to below 8¢ per kilowatt hour.

Advancements in the technology and the use of low-cost thermal storage will allow future concentrating solar power plants to operate for more hours during the day and shift solar power generation to evening hours. Future advances are expected to allow solar power to be generated for 4¢–5¢ per kilowatt-hour in the next few decades.

How To Reduce Greenhouse Gas Emissions

You can easily and affordably reduce or eliminate your company's "carbon footprint." 

Did you know that the United States Congress will be passing the S. 2191 "Cap and Trade" Law in 2009?  Did you know that Supreme Court ruled in April (2008) that the EPA already has the authority to regulate Greenhouse Gas Emissions?  Cap And Trade narrowly passed in the U.S. House of Representatives, and is now in the U.S. Senate, who has threatened to make even greater reductions of Greenhouse Gas Emissions in their final Bill of the Cap And Trade legislation. 

Are you ready for these new regulations?  We can help you get ready!

According to Monty Goodell, MBA, the Founder and Chairman of the Renewable Energy Institute, “Greenhouse Gas Emissions and Carbon Dioxide Emissions will be the world’s biggest commodity market and will probably soon be the world’s largest market, period." In fact,  Mr. Goodell anticipates that Greenhouse Gas Emissions and Carbon Dioxide Emissions will become one of the fasting-growing commodities and markets ever.

Every day, leading companies are spending millions of dollars going "GREEN" and reducing their Greenhouse Gas Emissions.

The Greenhouse Gas Emissions and Carbon Dioxide Emissions Market Potential is staggering!  According to a recent New York Times article, carbon trading is one of the “fastest-growing specialties in financial services.” 

Already, Greenhouse Gas Emissions Trading and International Carbon Trading markets are worth in excess of $50 billion/year. The United Nations expects this market to be valued in excess of $2 Trillion/year by 2012 and others are saying this could easily exceed $5 Trillion/year within the next several years!

DO THE MATH on the Carbon Dioxide Emissions market! 

You may be wondering, how can such a relatively new commodity grow so rapidly?  Here in the USA, 40 billion tons of Carbon Dioxide Emissions are produced every year. At the present price of $50 per ton of carbon dioxide, the Carbon Dioxide Emissions market is valued at $2.0 Trillion (40 billion tons of Carbon Dioxide Emissions x $50.00/ton).

How to Reduce Your Carbon Footprint

Carbon Emissions, Carbon Dioxide Emissions, and Greenhouse Gas Emissions can be reduced or completely eliminated with renewable energy technologies, such as our Solar Energy Systems - including our super high efficiency Solar Cogeneration and Solar Trigeneration energy systems.  Brown buildings can be upgraded in to green buildings and  "Net Zero Energy Buildings" through the products and services that we offer.

_______________________________________________

Monty Goodell, MBA, Founder and President of the Renewable Energy Institute, along with the Renewable Energy Institute's Scientific Advisory Board, which is comprised of several of our nation's leading experts, engineers, attorneys, professors and universities, is calling for our nation and all 50 states to adopt a Renewable Portfolio Standard (RPS) of at least 25% by 2025.

And even better than a Renewable Portfolio Standard, according to Mr. Goodell, is a "Feed In Tariff," which is the route Germany took, and why they have had such great success in their transition to a solar based economy. The fastest paths to jump-start the renewable energy industry, is through a "Feed In Tariff. 

A Feed In Tariff is superior to a Renewable Portfolio Standard," according to Mr. Goodell.  "For example, look at Germany's success in their transition to an economy based on the installation of solar energy systems, they adopted a Feed In Tariff, are further north from the Equator than we are here in the U.S., and they are placing solar panels on every rooftop and wind turbine generators throughout their country. They are leading the world in renewable energy technologies, primarily due to their early adoption of a Feed In Tariff"

What is a Feed In Tariff? 

A Feed In Tariff is a utility rate that is established by a state or federal government, that requires a utility to pay higher electricity rates for green electricity generated by the owners of the solar energy systems, whether that is a homeowner or business owner. Feed In Tariffs shifts the expenses of subsidizing green energy from taxpayers, to electricity ratepayers. Feed In Tariffs also include guarantee that the Feed In Tariffs' artificially higher rates, will continue for periods as long as 25 years.  

Germany's great success for jump-starting the solar energy industry there, first established Feed In Tariffs in 1999.  Germany now has about five times as many solar photovoltaic panels installed as the United States - even though their total combined installations of PV panels  still only account for about 0.5% of the electricity generated there. 

"So, we go with a Feed In Tariff in lieu of a Renewable Portfolio Standard.  Simultaneously, we need to start re-building our national electric grid, and transforming it into 'Transmission Superhighway' or 'Unified Smart Grid' and dramatically increase the nation's power supply as well as implement greater use of 'Energy Efficiency Measures' - also referred to as Energy Conservation Measures.  And we need to implement "real" 'Demand Side Management' programs.  Failure to move in these areas and to do so immediately increases the risks to our country, our national security and the climate" according to Mr. Goodell. 

According to Mr. Goodell, our nation is at a crossroads and we have been 'over the Middle Eastern barrel of their fossil fuels' long enough. We must shift from energy dependence to energy independence and place significant emphasis and investments in our national energy security and lower greenhouse gas emissions.    

Renewable energy, and only renewable energy provides the significant economic and environmental dividends our country now needs.  Preferably, our fledgling renewable energy  industry in the U.S., will be "jump-started" with a Feed In Tariff.  

Some of the economic and environmental dividends that renewable energy will provide our country, include:

• Creation of more than 3 million new jobs in the U.S..

• Generate more than $1 trillion in economic impacts

• Eliminates or Reduces Carbon Emissions and Greenhouse Gas Emissions

• Significant reductions of oil imports

• Reduce energy prices and save consumers as much as $50 billion on their energy bills

• Elimination of billions of pounds of carbon dioxide emissions and other greenhouse gas emissions

• Stimulate rural economies

• Conserve natural gas supplies 

• Creates a clean, safe energy future

• Position the US as a world leader in renewable energy technologies

The renewable energy industry, single-handedly, provides a powerful argument and solutions for these problems. 

Global warming and climate change are symptoms of a sick planet and the results of unrestrained "dumping" of huge amounts of pollution - in the form of carbon dioxide emissions and greenhouse gas emissions into the atmosphere.

The vast majority of carbon dioxide emissions and greenhouse gas emissions comes from "dirty" fossil fuels (coal, oil, and natural gas) used in making electricity at power plants and dirty fuels (gasoline and petroleum diesel) that run our internal combustion engines in our cars, trains, planes, and trucks. Our planet is home to millions and millions of internal combustion engines that run on dirty fossil fuels - whether they are fueled with gasoline for running our cars and lawnmowers or running on diesel fuel in the engines of trucks and ships like the very large crude carriers that transport the crude oil all around the world...... every internal combustion engine that is running on dirty fossil fuels is dumping millions and millions of tons of carbon dioxide emissions and greenhouse gas emissions into our atmosphere - which is aggravating and exacerbating our sick planet - and making manmade climate change and global warming more difficult to resolve through manmade remedies and solutions.

According to Monty Goodell, MBA, the Chairman and Founder of the Renewable Energy Institute, "our country desperately needs to upgrade its' national electric grid.  The grid of today is a relic from the past, that is inefficient and costly.  Originally built in the 1930's, it is costing our nation approximately $120 billion every year due to its' outdated and out-lived existence.  The national power grid as designed and built in the 1930's does not have the efficiencies and capabilities to keep pace with the national power grid's demands of today." 

"What we need" according to Mr. Goodell, is what former Vice President Al Gore calls a "Unified Smart Grid" or what we prefer to call a "Transmission Superhighway."

A Transmission Superhighway would be buried underground and "wheels" or transmits the renewable power ("green electricity") from the wind farms of the midwest, and solar farms of the southwest, and geothermal farms of the west, to load centers throughout every corner of the U.S."

According to many estimates, the "Unified Smart Grid" or "Transmission Superhighway" could be built for about $400 billion.  Through its' increased efficiencies, savings and reliability improvements that it will provide, the nation's new "unified smart grid" will be paid in full, in less than 4 years. 

__________________________________________________________________

The carbon clock tracks total Carbon Dioxide Emissions in metric tons since 1750.  Since 1750, humans have produced over 5 trillion pounds of Carbon Dioxide Emissions into the atmosphere. 

Roughly half of these Carbon Dioxide Emissions have ended up in the oceans where it is beginning to damage the coral reefs. The other half is still in the atmosphere and causing global warming. 

Each pound of Carbon Dioxide ("CO2") takes up as much space as a 500 pound person.

The formula (which should be good for a year or two) is:
C(t) = 2.58 ×1012 + 1240×t, where t is seconds since the start of 2007.

C is tonnes (metric tons) of Carbon Dioxide Emissions.

2205 x C gives pounds of Carbon Dioxide Emissions.

That comes to over 43 billion tons/year or over 86 trillion pounds/year.

Carbon dioxide is made up from 1 carbon atom with 2 oxygen atoms, or simply, "CO2."

Carbon has relative weight 12 and Oxygen 16.  Therefore, it takes only 12 pounds of carbon to make 12+16+16 = 44 pounds of Carbon Dioxide (CO2).

Carbon Dioxide Emissions have caused
CO2 concentrations in the atmosphere
to reach 387 ppm - over 100 ppm
higher than pre-industrial revolution
levels that were at 280 ppm

According to R. James Woolsey, for Director of the Central Intelligence Agency, "The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems --- they are aspects of a single problem, the West's dependence on oil." 

__________________________________________________________________

The Renewable Energy Institute has determined "carbon free energy" and "pollution free power" are the best possible solutions for the many economic, environmental and political/geo-political and societal problems caused by fossil fuels. 

The Renewable Energy Institute is made up of the brightest minds, professors, climatologists, engineers, politicians and universities.  Their "crystal ball" sees "renewable energy" and "renewable energy technologies" as the best path forward for providing the energy the world needs. And it's no longer any energy that will do - the future is for energy that is clean, sustainable, renewable, and "Carbon Free Energy" and "Pollution Free Power."

According to Monty Goodell, MBA the Founder and Chairman of the Renewable Energy Institute, "we must  become less dependent on unstable, foreign oil and energy supplies and reduce our 'addiction' to fossil fuels so that we can become energy independent - so that we will not be held hostage by counties with large supplies of fossil fuels such as Iran, Venezuela or Russia, countries that we cannot rely on as our allies or friends."

Continuing, Mr. Goodell adds, "Since energy and power are the lifeblood of our economy - and we need to 'transition' away from the use of all fossil fuels, and ultimately discontinue the use of fossil fuels so that we can stop and reverse the pollution from Carbon Dioxide Emissions and Greenhouse Gas Emissions. So, this begs the question, 'how do we provide for the energy and power that we need that keeps our economy healthy'? The answer and the future is quite simply, renewable energy resources integrated with renewable energy technologies, along with Clean Power Generation in the form of "Carbon Free Energy" and "Pollution Free Power."

Renewable energy and fuel includes;  B100 Biodiesel, Biomass / Biomass Gasification, Biomethane, E100 Ethanol, Geothermal, Solar, Waste to Energy (including Waste to Fuel and Waste to Watts) and Wind.  These renewable energy technologies produce ""Carbon Free Energy" and "Pollution Free Power."  This will reverse the problems caused by fossil fuels which include global warming and climate change.  Renewable energy technologies will improve our country's energy security, economy and reduce the trade deficit.

What is "Net Zero Energy^sm?"

Net Zero Energy^sm - when applied to a home or commercial building, simply means that the home or buildings generates as much power and energy as they consume, when measured on a monthly or annual basis, and with an onsite, renewable energy system, such as our Solar Trigeneration^sm Energy System. 

What is a Net Zero Energy Building^sm?

A Net Zero Energy Building^sm produces as much energy as it uses over the course of a year. Net Zero Energy Buildings^sm are very energy efficient. The remaining low energy needs are typically met with on-site renewable energy. 

First of all, understand that there is no such thing as a "zero energy building!" EVERY building uses energy, or you may as well be in a cave!  

The important considerations are, 

1.  How efficient is the building?  

2.  How much energy does the building use, and how efficiently is it used?  

3.  How much "carbon free energy" or "pollution free power" is generated by the buildings' own onsite renewable energy system?

4.  What are the utility company's prices for the excess power generated and sent to the grid? 
(see: Net Energy Metering)

5.  How difficult is it to interconnect the renewable energy system of the building with the utility company's powerlines/electric grid?   

At the heart of a Net Zero Energy Building^sm is the idea that any building can meet its energy requirements from low-cost, locally available, nonpolluting, renewable sources, like our Solar Trigeneration^sm Energy Systems. Our Solar Trigeneration^sm Energy Systems are the idea whose time has come, to make Net Zero Energy Buildings^sm commonplace.

Solar Trigeneration^sm Energy Systems Provide All of the Cooling, Heating & Power, for Any Size Building, with only the Energy of the Sun. Solar Trigeneration^sm Energy Systems Provide Simultaneous  Cooling, Heating & Power whether it is 12 Noon, or 12 Midnight,  and can do so, WITHOUT Connection to the electric grid!

The Diagram Below Shows How Our Solar Trigeneration^sm Energy System Works, 
for Heating and Cooling a Building (next to the Solar Thermal Collectors, are the PV Panels, that generate the Electricity).

Our Solar Trigeneration^sm Energy System
provides "Cooling, Heating & Power" for your business,
or home with the free energy of the sun!

What is Net Energy Metering?

Net energy metering is used to measure a customer's total electric consumption against that customer's total on-site electric generation.  When a customer's onsite generation of power exceeds the amount that they use, the customer's solar energy system (or other renewable energy system) exports the extra electricity to the grid.  When the power requirements of the customer exceeds their onsite generation of power, the customer imports the electricity they need from electric grid. The customer pays the electric company for any extra power they use over the amount they generate - OR -  the customer receives a credit or refund from the electric company if they exported more power to the grid, than what they consumed.  

Renewable Energy Is Necessary for Net Zero Energy Buildings

Much focus is placed on energy efficiency as the most cost-effective way to reduce energy use in commercial buildings. However, consumption can be reduced only so much. There is a point at which the cost of adding efficiency measures is higher than that of using renewable energy such as thin film photovoltaics and other solar energy systems. 

Aggressive energy efficiency strategies can reduce a building's energy consumption by 50% to 70%. Renewable energy technologies must be used to reach the goal of a net-zero energy building (NZEB).

Supply-Side Technologies

Various supply-side renewable energy technologies are available for Net Zero Energy Buildings. Supply-side technologies, often called energy producers, collect natural energy and transform it into a useful form. Examples of these technologies include PV, solar hot water, wind, hydroelectric, and biofuels.

Ranking of Energy Options

All renewable sources are favorable over conventional energy sources such as coal and natural gas; however, the U.S. Department of Energy recommends the following ranking for these options (the lower numbers are preferable):

This hierarchy is weighted toward renewable technologies within the building footprint and site. Rooftop PV and solar water heating are the most applicable supply-side technologies for Net Zero Energy Buildings. Other supply-side technologies such as parking lot-based wind or solar energy systems may be available.

The goal in developing the ranking was to encourage technologies that:

• Minimize overall environmental impact by encouraging energy-efficient building designs and reducing transportation and conversion losses

• Will be available over the lifetime of the building

• Are widely available and have high replication potential for future Net Zero Energy Buildings.

By:  Monty Goodell, MBA

Los Angeles, California

There is now a better, more efficient, “pollution free power” and "carbon free energy" solution for cooling, heating and powering homes and commercial buildings where solar energy is available. It's called Solar Trigeneration.

Solar Trigeneration is defined as the simultaneous generation of cooling, heating and power with only the free solar energy from the sun providing the "fuel". 

Solar Trigeneration is now a reality at the Audubon Center at Debs Park several miles from downtown Los Angeles and is one of the world's first "Net Zero Energy Buildings." Net Zero Energy Buildings." Net Zero Energy Buildings."

The Audubon Nature Center is totally powered by the sun’s energy and our Solar Trigeneration energy system!

The 5,300 square foot building operates entirely “grid-free” and without any electric connections to the electric grid, or natural gas connections – a truly sustainable power and energy solution. 

Best of all, the Audubon Center doesn’t rely on the over-burdened electric grid or even natural gas.  Therefore, the Audubon Nature Center NEVER receives an electric bill or natural gas bill.... ever!

The Audubon Nature Center's 5,000 square foot office and conference facility is powered by a Solar Trigeneration system that features a 25-kilowatt solar electric power system where the energy is stored in a bank of batteries. The Center is cooled by a 10-ton solar absorption cooling system powered by an array of very efficient solar heat pipe vacuum tube thermal collectors.  The collectors heat the water to temperatures of 200+ degree F stored in a 1,200 gallon insulated tank, another type of inexpensive battery. The Solar Trigeneration system at the Audubon not only provides the air-conditioning in the summer but also heats the building in the winter, and provides the hot water for the kitchen and bathrooms. 

Absorption chillers, and cooling with solar energy with an absorption chiller are not new technologies.  In fact, absorption chiller technology is over 70 years old.  The first refrigerators were powered by propane gas to run the absorption chillers that used ammonia as a refrigerant.  Electricity and the electric compression chiller gained popularity only because of the convenient “plug and play” appliance and relatively cheap electric rates.  Electricity is no longer economically, or environmentally “cheap.”

History of Cogeneration and Trigeneration

Few people realize that the world's first commercial power plant, designed and built by Thomas Edison, was a cogeneration power plant that was first opened on Pearl Street, in Lower Manhattan, New York.  That was in 1882!  Edison not only generated, and sold electricity in the several blocks surrounding his "Pearl Street Station" but he also sold the hot water that was also generated from the cogeneration plant. The fuel Edison used for generating the electricity and hot water (cogeneration) came from "pulverized coal." The Pearl Street Station provided 110 volts of "direct current" power to 59 customers in lower Manhattan, around his Pearl Street laboratory. 

Cogeneration is the simultaneous production of heat and power. 

Trigeneration is the simultaneous production of cooling, heating and power.

Our company, in partnership with the Renewable Energy Institute and our affiliated partners, have perfected "Solar Cogeneration" and "Solar Trigeneration" which are the "heart" of our Net Zero Energy Buildings.

Unlike traditional cogeneration and trigeneration power plants that are fueled by natural gas - and Thomas Edison's cogeneration plant, which was fueled with pulverized coal, our Solar Cogeneration and Solar Trigeneration energy systems are fueled with the energy of the sun!  And, while natural gas is a "cleaner" fuel, it still has its problems in that it is a limited resource and generates greenhouse gas emissions.  Natural gas also have had extreme price swings and has a history of price volatility.  Natural gas prices have gone from a high of $17.00/mmbtu to a recent low of under $3.00/mmbtu.  

Regarding pulverized coal, yes, it's cheap in terms of the cost of generating electricity, but too many people forget about the "externalities" of pulverized coal that is not reflected in the "cheap" costs of generating electricity from pulverized coal.  These costs not accounted for are the huge environmental cost relating to the use of pulverized coal.  Pound for pound, pulverized coal and coal fired power plants generate more greenhouse gas emissions than any other fossil fuel.  There are also the costs related to the health and safety issues of the miners that mine the coal.  And, the costs to the environment in terms of the ever-increasing amounts of mercury that are "dumped" into the environment from coal fired power plants, is also not reflected in the "cheap" price of generating power from pulverized coal.

Unlike the problems inherently found with the use of fossil fuels, Solar Cogeneration and Solar Trigeneration have no such problems. 

And talk about "cheap" costs of generating power and energy, there is nothing cheaper than free!!!!  

The owners of the Audubon Nature Center never receive any monthly natural gas or electric bills!

And the owners of the Audubon Nature Center will never have to account for their greenhouse gas emissions, or comply with the ever-increasing regulations related to greenhouse gas emissions and the pending Cap and Trade laws..... thanks to our  Solar Trigeneration energy system!

Solar Trigeneration is an EcoGeneration solution.  EcoGeneration refers to a power and energy system that uses the “natural” energy or fuel that is available for a specific site or location. Such energy or fuel includes, solar, wind, BioMethane, geothermal, and ocean power, including ocean tidal and ocean thermal energy conversion. For example, in the desert areas of the Southwestern U.S. , there is an abundance of solar energy. Therefore, home-owners and business owners in this part of the country should seriously consider an EcoGeneration system (“ecogen system”) that optimizes the opportunities available through solar energy

Today, the cause of the summer peak electric demand, electric supply problems, and black-outs, are the result of the energy crisis in California, primarily attributed to the air conditioning load. Over 40 percent of the electricity generated every day goes is used for air conditioning.  At this time of year, the electric utilities are forced to turn on all of their power plants to generate the “peak” demands required by the customers, primarily for air-conditioning.  This means that all of the efficient power plants, the inefficient power plants, along with all of the “peaking” power plants have to run to generate the electricity needed. The high cost of meeting the peak demand is passed on to the consumers with rates of $.20+ per kWh during the summer months. For fixed income seniors living in desert communities, they are already forced to conserve on energy, food, water, and other necessities of life. 

Greater Demands on California’s Limited Electric Supply, Lack of New Electric Power Supplies, and This Summer’s Heat Wave are Compounding the Problem Leading to the “Perfect Electric Storm”

Many people will remember the movie “The Perfect Storm” from several years ago, when several storms came together in the northeastern part of the U.S. to produce a deadly and catastrophic “perfect” storm. Today, a different type of “perfect storm” is brewing in California. The storm that’s looming on the horizon in California is a “perfect electric storm” wherein the supply of electricity from the electric utility company’s power plants are unable to keep-up with the demand – meaning a black-out, or loss of electricity, like the black-outs from previous years, and like the northeastern black-out from 2003.

The most likely time of year for a black-out in California, unfortunately, is the summer, when air-conditioners are running at the maximum, and placing the maximum load on California’s electricity supply.  Should such a black-out occur in the desert areas of California, where daily high temperatures routinely reach 110 degrees and higher, and where a significant percentage of the population is comprised of retired and senior citizens, and should the black-out be prolonged, a number of deaths will be the likely outcome. People, and especially the elderly, simply cannot tolerate prolonged high temperatures

How Do We Prevent the “Perfect Electric Storm” from Occurring in California and Other Regions in the U.S.?

Another major concern is how do we prevent the “Perfect Electric Storm” from happening, like the Northeast Blackout several summers ago, especially for people living in the desert?  California ’s energy authorities are warning of a possible energy crisis during the hot summer months, due to the excessive and prolonged summer temperatures where demand increases by over 40 percent.  Compounding the problem is the rising demand for electricity due to population growth and the limited transmission capacity in some areas in the region.  According to the California Energy Commission, the State must build three natural gas-fired 500-megawatt peaking power plants, every year, just to keep up with the growing demands of electricity. Failure to keep up with demand means The problem is getting worse due to the population growth in the Inland Empire , Coachella Valley and Antelope Valley. The projected power gap for the coming summers remains bleak.

Governor Schwarzenegger’s “Million Solar Roofs” program and the passage of the 2005 Federal Energy Act will be the foundation to create a “Perfect Solar Storm” to trigger the Solar Economy throughout California. 

With the threat of California’s seniors and elderly dying from heat exhaustion due to power outages, black-outs, rolling black-outs and the rising costs of electricity and natural gas, combined with the continuing impact of global warming, the perfect solution is to create a Solar Revolution by cooling, heating and powering the desert with solar energy and technologies like Solar Cogeneration or Solar Trigeneration.

What is "Copper Indium Gallium Diselenide?"

Copper Indium Gallium diSelenide (CuInSe2) is a material that provides an extremely high absorption of light ( 99%) to be absorbed in the first micron of the material. Copper Indium Gallium diSelenide is projected to be the revolutionary material that some are saying, could put typical "central" power plants and some electric utilities, out of business, as it will be much cheaper for customers to generate their own onsite power with Thin Film Photovoltaics made from these materials.   

When additional small amounts of Gallium is added to Copper Indium diSelenide, this increases its' light-absorbing band gap, thereby making the solar panel more closely match the solar spectrum of the sun.  This, in turn, increases the voltage and the efficiency of the Thin Film Photovoltaics solar panel. 

Solar panels produced with Copper Indium Gallium diSelenide cells have reached efficiencies of more than 20% - which is much higher than the other Thin Film Photovoltaics. 

Copper Indium Gallium diSelenide solar panels create more electricity from the same amount of sunlight than other Thin Film Photovoltaics panels.  This translates into a higher conversion efficiency. 

The conversion efficiency of Copper Indium Gallium diSelenide PV technologies is very stable over time, meaning its power output remains stable over many years, while the power output of many other PV materials can rapidly decline with time. 

What are "Building Integrated Photovoltaics?"

Building Integrated Photovoltaics (BIPV) are solar energy systems that are integrated into a part of the building, that serve as the building's exterior or the building's skin. 

Commercial buildings and facilities (including houses) that integrate their own solar power systems into the building's exteriors, are referred to as "power buildings."

The technology that makes this possible is "Thin Film Photovoltaics."

What are Thin Film Photovoltaics?

Without a doubt, the most exciting technology in the solar power industry is "Thin Film Photovoltaics."  Thin Film Photovoltaics technology represents the next big thing in renewable energy and solar power as it integrates nanotechnologies into the production of solar photovoltaics. 

According to the Department of Energy, the recent technological advances in thin film photovoltaics make this a very exciting time to be in the solar energy industry.  These advances have led to many new developments in the components and manufacturing of thin film photovoltaics. This has made thin film photovoltaics cheaper to manufacture as they are also now easier to install since they are extremely versatile, flexible, bendable, and much lighter.

Thin film photovoltaics  have led many to believe that as much as 50% of our nation's future power will be generated by "power buildings" that integrate "building integrated photovoltaics" or "BIPV" into the building's skin or exterior surfaces, that convert sunlight into "pollution free power" for use in the building.  This also designates these buildings (and homes) as "Net Zero Energy Buildings" and make the option for going grid-free, or not connecting to the grid, a real possibility.

According to the Department of Energy, the market potential for printed electronics will grow into a $47 billion market by 2018.  Thin film photovoltaics represents a significant portion of this market - and based on this heavily researched solar technology, thin film photovoltaics now represents a $20 billion/year industry in the U.S.

The solar PV panels produced under the thin film photovoltaics umbrella have the potential to produce power significantly cheaper power than today’s typical silicon-based PV panels.  The panels are usually made in the form of a monolithic piece of glass, upon which various thin films are deposited, although a number of firms are working on depositing the materials on a substrate, such as stainless steel or plastic.

Types of Thin Film Photovoltaics – there are primarily three types of thin film photovoltaics and include:

1. Amorphous Silicon

Absorption Chillers 
&
Adsorption Chillers

For Solar Trigeneration Applications

What Absorption Chillers and How Does They Work?

Absorption chillers use heat instead of mechanical energy to provide cooling. A thermal compressor consists of an absorber, a generator, a pump, and a throttling device, and replaces the mechanical vapor compressor.

In the chiller, refrigerant vapor from the evaporator is absorbed by a solution mixture in the absorber. This solution is then pumped to the generator. There the refrigerant re-vaporizes using a waste steam heat source. The refrigerant-depleted solution then returns to the absorber via a throttling device. The two most common refrigerant/ absorbent mixtures used in absorption chillers are water/lithium bromide and ammonia/water.

Compared with mechanical chillers, absorption chillers have a low coefficient of performance (COP = chiller load/heat input). However, absorption chillers can substantially reduce operating costs because they are powered by low-grade waste heat. Vapor compression chillers, by contrast, must be motor- or engine-driven.

Low-pressure, steam-driven absorption chillers are available in capacities ranging from 100 to 1,500 tons. Absorption chillers come in two commercially available designs: single-effect and double-effect. Single-effect machines provide a thermal COP of 0.7 and require about 18 pounds of 15-pound-per-square-inch-gauge (psig) steam per ton-hour of cooling. Double-effect machines are about 40% more efficient, but require a higher grade of thermal input, using about 10 pounds of 100- to 150-psig steam per ton-hour.

In single-effect absorption chillers, all condensing heat cools and condenses in the condenser. From there it is released to the cooling water. A double-effect machine adopts a higher heat efficiency of condensation and divides the generator into a high-temperature and a low-temperature generator.

Actions You Can Take

Determine the cost-effectiveness of displacing a portion of your cooling load with a waste steam absorption chiller by taking the following steps:

• Conduct a plant survey to identify sources and availability of waste steam

• Determine cooling load requirements and the cost of meeting those requirements with existing mechanical chillers or new installations

• Obtain installed cost quotes for a waste steam absorption chiller

• Conduct a life cycle cost analysis to determine if the waste steam absorption chiller meets your company's cost-effectiveness criteria.

Absorption Chillers Refrigeration Cycle

The basic cooling cycle is the same for the absorption and electric chillers. Both systems use a low-temperature liquid refrigerant that absorbs heat from the water to be cooled and converts to a vapor phase (in the evaporator section). The refrigerant vapors are then compressed to a higher pressure (by a compressor or a generator), converted back into a liquid by rejecting heat to the external surroundings (in the condenser section), and then expanded to a low- pressure mixture of liquid and vapor (in the expander section) that goes back to the evaporator section and the cycle is repeated.

The basic difference between the electric chillers and absorption chillers is that an electric chiller uses an electric motor for operating a compressor used for raising the pressure of refrigerant vapors and absorption chillers use the heat for compressing refrigerant vapors to a high-pressure. The rejected heat from the power-generation equipment (e.g. turbines, microturbines, and engines) may be used with an absorption chiller to provide the cooling in a CHP system.

The basic absorption cycle employs two fluids, the absorbate or refrigerant, and the absorbent. The most commonly fluids are water as the refrigerant and lithium bromide as the absorbent. These fluids are separated and recombined in the absorption cycle. In the absorption cycle the low-pressure refrigerant vapor is absorbed into the absorbent releasing a large amount of heat. The liquid refrigerant/absorbent solution is pumped to a high-operating pressure generator using significantly less electricity than that for compressing the refrigerant for an electric chiller. Heat is added at the high-pressure generator from a gas burner, steam, hot water or hot gases. The added heat causes the refrigerant to desorb from the absorbent and vaporize. The vapors flow to a condenser, where heat is rejected and condense to a high-pressure liquid. The liquid is then throttled though an expansion valve to the lower pressure in the evaporator where it evaporates by absorbing heat and provides useful cooling. The remaining liquid absorbent, in the generator passes through a valve, where its pressure is reduced, and then is recombined with the low-pressure refrigerant vapors returning from the evaporator so the cycle can be repeated.

Absorption chillers are used to generate cold water (44°F) that is circulated to air handlers in the distribution system for air conditioning.

"Indirect-fired" absorption chillers use steam, hot water or hot gases steam from a boiler, turbine or engine generator, or fuel cell as their primary power input. Theses chillers can be well suited for integration into a CHP system for buildings by utilizing the rejected heat from the electric generation process, thereby providing high operating efficiencies through use of otherwise wasted energy.

"Direct-fired" systems contain natural gas burners; rejected heat from these chillers can be used to regenerate desiccant dehumidifiers or provide hot water.

Commercially, absorption chillers can be single-effect or multiple-effect. The above schematic refers to a single-effect absorption chiller. Multiple-effect absorption chillers are more efficient and discussed below.

Multiple-Effect Absorption Chillers

In single-effect absorption chillers, the heat released during the chemical process of absorbing refrigerant vapor into the liquid stream, rich in absorbent, is rejected to the environment. In a multiple-effect absorption chiller, some of this energy is used as the driving force to generate more refrigerant vapor. The more vapor generated per unit of heat or fuel input, the greater the cooling capacity and the higher the overall operating efficiency.

Double-effect absorption chillers uses two generators paired with a single condenser, absorber, and evaporator. It requires a higher temperature heat input to operate and therefore they are limited in the type of electrical generation equipment they can be paired with when used in a CHP System.

Triple-effect absorption chillers can achieve even higher efficiencies than the double-effect chillers. These absorption chillers require still higher elevated operating temperatures that can limit choices in materials and refrigerant/absorbent pairs. Triple-effect chillers are under development by manufacturers working in cooperation with the U.S. Department of Energy.

What is Concentrating Solar Power?

Concentrating solar power plants produce electric power by converting the sun's energy into high-temperature heat using various mirror configurations. The heat is then channeled through a conventional generator. The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts heat energy to electricity.

Concentrating solar power systems can be sized for village power (10 kilowatts) or grid-connected applications (up to 100 megawatts). Some systems use thermal storage during cloudy periods or at night. Others can be combined with natural gas and the resulting hybrid power plants provide high-value, dispatchable power. These attributes, along with world record solar-to-electric conversion efficiencies, make concentrating solar power an attractive renewable energy option in the Southwest and other sunbelt regions worldwide.

Why Concentrating Solar Power is one of the Few "Superior" 
Renewable Energy Technologies

Concentrating solar power plants use the high annual solar irradiance of the geographic location to generate "carbon free energy" and "pollution free power."  

For generating power after the sun sets, many owners/developer of concentrating solar power plants are now installing "Molten Salt Storage" systems that reserves enough energy to allow for electricity generation throughout the nighttime period.  

Steam turbines and gas turbines powered by coal, uranium, oil and natural gas are the fuels used today for generating power and electric grid stability.  These fuels provide both base-load and peak power.  However, these same steam turbines can also be powered by the high temperature
heat from concentrating solar power plants. 

Concentrating solar power plants in the 30 MW - 200 MW range are now operating successfully in locations from California to Europe.  Nearly every day now, new concentrating solar power plants are being planned for construction.  The concentrating solar collectors are very efficient and they also completely replace the fossil fuels that were used in traditional power plants.  Today's concentrating solar power plants generate the heat needed to generate electricity at a cost equivalent to $50 - $60 per barrel of oil (equivalent).  This cost is expected be slashed by 50% to below $25 - $30 per barrel in the next 10 years.  

Just like conventional fossil-fueled power plants, concentrating solar power plants generate  base-load and peaking power electricity.  

Just like fossil fuel fired conventional power plants, concentrating solar power plants have an availability that is close to 100 %, but without the carbon emissions, carbon dioxide emissions, hazardous air pollutants, nitrogen oxides, volatile organic compounds and greenhouse gas emissions that fossil fuel power plants emit.

A concentrating solar power plant with a molten salt storage facility for full load operation during the nighttime period is currently being built in the Spanish Sierra Nevada near Guadix. This concentrating solar power plant will generate 50 MW of power.

Another feature that distinguishes concentrating solar power plants is the opportunity for combined generation of heat and power - a technology that is called "Integrated Solar Combined Cycle" which achieves the highest possible efficiencies for energy conversion. In addition to power generation, such plants can provide steam for absorption chillers and/or adsorption chillers, industrial process heat or thermal ocean water desalination. A design study for such a plant was completed in 2006.  This plant is scheduled to be commissioned in early 2009. This Integrated Solar Combined Cycle will provide 10 MW of power, 40 MW of district cooling and 10,000 cubic meters per day of desalted water for a large hotel in Jordan.

Solar Electric Power Systems (PV)

Solar electric power systems transform sunlight into electricity. Sunlight is an abundant resource. Every minute the sun bathes the Earth in as much energy as the world consumes in an entire year. Solar cells employ special materials called semiconductors that create electricity when exposed to light. Solar electric systems are quiet and easy to use, and they require no fuel other than sunlight. Because they contain no moving parts, they are durable, reliable, and easy to maintain. How It Works Solar cells, also known as photovoltaic (PV) cells, do the work of making electricity. Several types of solar electric technology are under development, but four—crystalline silicon (a form of refined beach sand), thin films, concentrators, and thermophotovoltaics—are illustrative of the range of technologies. Solar cells are connected to a variety of other components to make a solar electric power system. Crystalline Silicon Crystalline silicon solar cells are used in more than half of all solar electric devices. Like most semiconductor devices, they include a positive layer (on the bottom) and a negative layer (on the top) that create an electrical field inside the cell. When a photon of light strikes a semiconductor, it releases electrons (see animation). The free electrons flow through the solar cell's bottom layer to a connecting wire as direct current (DC) electricity. Some solar cells are made from polycrystalline silicon, which consists of several small silicon crystals. Polycrystalline silicon solar cells are cheaper to produce but somewhat less efficient than single-crystal silicon. A simple silicon solar cell can power a watch or calculator. However, it produces only a tiny amount of electricity. Connected together, solar cells form modules that can generate substantial amounts of power. Modules are the building blocks of solar electric systems, which can produce enough power for a house, a rural medical clinic, or an entire village. Large arrays of solar electric modules can power satellites or provide electricity for utilities. Solar Electric Power System Components In addition to modules, several components are needed to complete a solar electric power system. Many systems include batteries, battery chargers, a backup generator, and a controller so that people in solar-powered homes and buildings can turn on the lights at night or run televisions or appliances on cloudy days. Grid-connected systems don't require batteries or backup generators because they use the grid for backup power. Some remote system applications, such as those used to pump water, do not require a backup power source. Components of a typical standalone PV system using crystalline silicon technology. (Source: Solar Electric Power Association) Solar electric power systems can incorporate inverters or power control units to transform the DC electricity produced by the solar cells into alternating current (AC) to run AC appliances or sell to a utility grid. Complete systems usually include safety disconnects, fuses, and a grounding circuit as well. Thin Films Solar electric thin films are lighter, more resilient, and easier to manufacture than crystalline silicon modules. The best-developed thin-film technology uses amorphous silicon, in which the atoms are not arranged in any particular order as they would be in a crystal. An amorphous silicon film only one micron thick can absorb 90% of the usable solar energy falling on it. Other thin-film materials include cadmium telluride and copper indium diselenide. Substantial cost savings are possible with this technology because thin films require relatively little semiconductor materials. Thin films are produced as large, complete modules, not as individual cells that must be mounted in frames and wired together. They are manufactured by applying extremely thin layers of semiconductor material to a low-cost backing such as glass or plastic. Electrical contacts, antireflective coatings, and protective layers are also applied directly to the backing material. Thin films conform to the shape of the backing, a feature that allows them to be used in such innovative products as flexible solar electric roofing shingles. Concentrators Concentrators use optical lenses (similar to plastic magnifying glasses) or mirrors to concentrate the sunlight that falls on a solar cell. With a concentrator to magnify the light intensity, the solar cell produces more electricity. Today, most solar cells in concentrators are made from crystalline silicon. However, materials such as gallium arsenide and gallium indium phosphide are more efficient than silicon in solar electric concentrators and will likely see more use in the future. These materials are now used in communications satellites and other space applications. Concentrators produce more electricity using less of the expensive semiconductor material than other solar electric systems. A basic concentrator unit consists of a lens to focus the light, a solar cell assembly, a housing element, a secondary concentrator to reflect off-center light rays onto the cell, a mechanism to dissipate excess heat, and various contacts and adhesives. The basic unit can be combined into modules of varying sizes and shapes. Concentrators only work with direct sunlight and operate most effectively in sunny, dry climates. They must be used with tracking systems to keep them pointed toward the sun. Thermophotovoltaics Thermophotovoltaic (TPV) devices convert heat into electricity in much the same way that other PV devices convert light into electricity. The difference is that TPV technology uses semiconductors "tuned" to the longer-wavelength, invisible infrared radiation emitted by warm objects. This technology is cleaner, quieter, and simpler than conventional power generation using steam turbines and generators. TPV converters are relatively maintenance-free because they contain no moving parts. In addition to using solar energy, they can convert heat from any high-temperature heat source, including combustion of a fuel such as natural gas or propane, into electricity. TPV converters produce virtually no carbon monoxide and few emissions. They may be used in the future in gas furnaces that generate their own electricity for self-ignition (during power outages) and in portable generators and battery chargers. Advantages Solar electric systems offer many advantages. Standalone systems can eliminate the need to build expensive new power lines to remote locations. For rural and remote applications, solar electricity can cost less than any other means of producing electricity. Solar electric systems can also connect to existing power lines to boost electricity output during times of high demand such as on hot, sunny days when air conditioners are on. Solar electric systems are flexible. Solar electric modules can stand on the ground or be mounted on rooftops. They can also be built into glass skylights and walls. They can be made to look like roof shingles and can even come equipped with devices to turn their DC output into the same AC utilities deliver to wall sockets. These advances mean individual homeowners and businesses can relieve pressure on local utilities struggling to meet the increasing demand for electricity. More than 30 states offer grid-connected solar electric system owners the chance to save money on their energy bills by feeding any excess power their solar electric system produces into the utility grid—an arrangement called net metering. Solar power systems require minimal maintenance. They run quietly and efficiently without polluting. They are easy to combine with other types of electric generators such as wind, hydro, or natural gas turbines. They can charge batteries to make solar electricity continuously available. For utilities, large-scale solar electric power plants can help meet demand for new power generation, especially in distributed applications. A solar electric power plant is created from multiple arrays that are interconnected electronically. Solar electric plants are easier to site and are quicker to build than conventional power plants. They are also easy to expand incrementally—by adding more modules—as power demand increases. Solar electric power systems are good for the environment. When solar electric technologies displace fossil fuels for pumping water, lighting homes, or running appliances, they reduce the greenhouse gases and pollutants emitted into the atmosphere. The use of solar electric systems is particularly important in developing nations because it can help avert the expected increases in emissions of greenhouse gases caused by the growing demand for electricity in those countries. Solar electric technologies also benefit the U.S. economy by creating jobs in U.S. companies. Exporting solar electric technologies to developing nations expands U.S. markets while protecting the global environment. Disadvantages Although solar electric systems make financial sense in remote areas that lack access to power lines, they are usually more expensive than fossil fuels for grid-connected applications. This disadvantage is significant for utilities considering large-scale solar electric power plants. Although solar electricity costs considerably more than electricity generated by conventional plants, regulatory agencies often require utilities to supply electricity for the lowest cash cost. Utilities view solar electric power plants differently than they view conventional power plants. Solar electric modules produce electricity intermittently—only when the sun shines. Their output varies with the weather and disappears altogether at night. Integrating solar electricity into a utility system requires creative planning. Applications A combination of solar electric arrays and pool-heating solar collectors were used to provide power and heat to the Georgia Tech University Aquatic Center, site of the 1996 Olympic swimming competition. (Credit: Heliocol) Solar electricity has powered satellites since the dawn of the space program. It has run remote communications outposts high in the mountains and turned on the lights, kept medicines cold, and pumped water in rural areas for more than 30 years. Small solar cells are used to power wristwatches, calculators, and other electronic gadgets. More recently, solar electric systems have been used to provide supplemental power to homes and commercial buildings in cities. Solar electric technology has important roles to play in both the developing and developed worlds. From the farmer irrigating his crops in rural Mexico to an innovative lighting system for an Olympic sports arena, solar electric solutions abound. Electric utilities harness solar electricity for distributed applications—near substations or at the end of overloaded power lines, for example, to avoid or defer costly line upgrades. They use solar electricity during hot, sunny periods when the demand for air conditioning stretches conventional power generation to its limit. The Sacramento Municipal Utility District, for example, uses large solar electric arrays as part of its power generation mix. Utilities also rely on solar electricity to power remote, standalone monitoring systems. Consumers and builders are integrating solar electric modules into their homes and offices. Innovative solar electric technologies can replace conventional roofing and facade materials in new buildings. Solar electric roofing shingles, for example, are being used in some new residences. In grid-connected applications, solar electricity supplies some of a consumer's energy needs; the local utility provides the rest. Standalone solar electric systems power a variety of applications far from the reaches of the power grid. These applications include remote communications systems such as television and radio transmitters and receivers, telephone systems, and microwave repeaters. Standalone solar electric power is also used to prevent corrosion of metal pipes, tanks, bridges, and buildings. Many remote residences worldwide use solar electricity as their source of power. For instance, more than 100,000 vacation homes in Scandinavia rely solely on solar electric technology to run lights and appliances. Villages around the world are building solar electric systems to bring electricity to their homes and local industries, often for the first time. To make the maximum use of available resources, village power is typically produced by a hybrid power system that combines solar electricity with diesel backup generators and sometimes another renewable energy technology such wind power. Villages also use standalone solar electric systems for pumping water—an application shared by rural farmers and ranchers in the United States.

What is "Decentralized Energy"?

Decentralized Energy is the opposite of "centralized energy."  Decentralized Energy energy generates the power and energy that a residential, commercial or industrial customer needs, onsite. Examples of decentralized energy production are solar energy systems and solar trigeneration energy systems.

Today's electric utility industry was "born" in the 1930's, when fossil fuel prices were cheap, and the cost of wheeling the electricity via transmission power lines, was also cheap.  "Central" power plants could be located hundreds of miles from the load centers, or cities, where the electricity was needed. These extreme inefficiencies and cheap fossil fuel prices have added a considerable economic and environmental burden to the consumers and the planet.

Centralized energy is found in the form of electric utility companies that generate power from "central" power plants. Central power plants are highly inefficient, averaging only 33% net system efficiency.  This means that the power coming to your home or business - including the line losses and transmission inefficiencies of moving the power - has lost 75% to as much as 80% energy it started with at the "central" power plant.  These losses and inefficiencies translate into significantly increased energy expenses by the residential and commercial consumers.

Decentralized Energy is the Best Way to Generate 
Clean and Green Energy! 

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:

What is an Assigned Amount (AA)?

The quantity of greenhouse gases that an Annex I country can release in accordance with the Kyoto Protocol, during the first commitment period of that protocol (2008-12).


What is an Assigned Amount Unit (AAU)?

An Assigned Amount Unit (AAU) is a tradable unit of 1 tCO2e.

What is a Certified Emission Reduction (CER)?

According to the Kyoto Protocol, a Kyoto Protocol unit equal to 1 metric tonne of CO 2 equivalent. A Certified Emission Reduction is issued for emission reductions from Clean Development Mechanism project activities. Two special types of Certified Emission Reductions called temporary Certified Emission Reductions (tCERs) and long-term Certified Emission Reductions (lCERs) are issued for emission removals from forestation and reforestation Clean Development Mechanism projects.


What is the Clean Development Mechanism (CDM)?

The Clean Development Mechanism is provided by Article 12 of the Kyoto Protocol, designed to assist developing countries in achieving sustainable development by permitting industrialized countries to finance projects for reducing greenhouse gas emission in developing countries and receive credit for doing so.

What is an Emission Reduction Purchase Agreement (ERPA)?

An Emission Reduction Purchase Agreement is a binding purchase agreement signed between buyer (of CERs or ERUs) and seller.


What are Emission Reduction Units (ERUs)?

A unit of emission reductions achieved through a Joint Implementation project. This unit is equal to one metric ton of carbon dioxide equivalent.


What are Emissions Reductions (ERs)?

Emissions reductions generated by a project that have not undergone a validation/verification process, but are contracted for purchase.

What is Emissions Trading?

Emissions Trading allows for the transfer of Assigned Amount Units across international borders or emission allowances between companies covered by a Cap and Trade program. However, it is a general term often used for the three Kyoto mechanisms: JI, CDM and emissions trading.


What is the Emissions Trading Scheme?

The ETS is the largest multi-national, greenhouse gas emissions trading scheme in the world and is a main pillar of EU climate policy.


What is an ERC?

An ERC refers to an Emission Reduction Credit.


What is the EU ETS?

European Union Emissions Trading Scheme.


What is an EUA?

An EUA refers to the European Union Allowance.


What is a European Union Allowance (EUA)?

A European Union Allowance Materialization of the EU ETS quotas, the tradable unit under the EU ETS. One EUA represents the right to emit 1 ton of CO2.


What is the European Union Emissions Trading Scheme (EU ETS)

Trading Scheme within the European Union. The first compliance phase is from 2005 to 2007, while the second compliance phase continues from 2008 to 2012.

What is a Renewable Energy Credit?

A Renewable Energy Certificate (REC) represents the equivalent of one megawatt hour of electricity generation from an accredited renewable energy source. 

What is a Verified Emission Reduction (VER)?

A Verified Emission Reduction is a unit of greenhouse gas emission reduction that has been verified by an independent auditor, but has not yet undergone the procedures and may not yet have met the requirements for verification, certification and issuance of Certified Emission Reductions (in the case of the Clean Development Mechanism) or ERUs (in the case of JI) under the Kyoto Protocol. 

Buyers of a Verified Emission Reduction assume all carbon-specific policy and regulatory risks (i.e. the risk that the VERs are not ultimately registered as either a Certified Emission Reduction or a Emission Reduction Credit). Buyers therefore tend to pay a discounted price for VERs, which takes the inherent regulatory risks into account. 

A Verified Emission Reduction is a carbon credit which is not certified under the Kyoto Protocol but which can be used to compensate carbon emissions. 1 Verified Emission Reduction corresponds to one metric tone of CO2 equivalent.


What is the Voluntary Market?

The Voluntary market is precisely that, a "voluntary" market for emissions reductions for buyers and sellers of a Verified Emission Reduction (VER), which seek to manage their emission exposure for non-regulatory purposes.

About the Renewable Energy Institute, Climate Science 
& America's Clear and Present Danger

Monty Goodell, MBA
Founder and Chairman
Renewable Energy Institute

The Renewable Energy Institute (REI) does not take a stand in the debate on global warming, and if there is, is it "anthropogenic" and not caused by the sun, sun spots, or the sun's normal cycles.  Or, is global warming and climate change caused by the water vapor in the atmosphere?

At the Renewable Energy Institute, we are waiting for the "true" scientists, doing the "real" research, to provide the science and answers, and not the phony scientists who are following the politically-motivated and profit-driven agendas of the United Nations and many countries and government leaders. These phony scientists are not interested in conducting real scientific research.  Their very livelihoods are dependent on the government grants to fund their phony research.  This "political-interference" by governments, governmental agencies, and so-called "leaders" that hand out billions of dollars for these phony scientists to conduct climate science and research,  expect the conclusions of the "research" to be tainted, skewed, flawed to support anthropogenic global warming, or climate change. Should these scientists accurately conclude in their research that they find no evidence of anthropogenic climate change or global warming, they are summarily dismissed, and black-balled from their communities and colleagues, and never again receive funding or grants.  This "politically-driven" process of providing funding and grants for real scientific research must stop.

In the meantime, far more harm is being done to our planet as well as to people and plants and animals, particularly fish, from the mercury emissions from coal fired power plants than from the coal fired power plants' greenhouse gas emissions.  We surmise that if any polar bears have died as a result of an environmental problem, it was more likely from the high levels of mercury in their food chain, than from greenhouse gas emissions. 

The Renewable Energy Institute is supporting and advancing renewable energy technologies, as well as reducing and eliminating greenhouse gas emissions and the fossil-fuel problems related to America's oil addiction and ending our dependence on foreign oil.  The renewable energy technologies we support are already deemed to be economic, viable and practical. Solutions such as Solar Trigeneration energy systems (see www.SolarTrigeneration.com for more information) for any kind of facility or building - office buildings, shopping centers, data centers, university campuses, etc. 

Since 2003, a Solar Trigeneration energy system has been providing 100% of the power and energy for a 5,300 sq. ft. office building near downtown Los Angeles, and doing so without any connection to the electric grid, whether its 12 noon or 12 midnite!  

The Renewable Energy Institute is also involved in research and advocacy of "Net Zero Energy" (see: www.NetZeroEnergy.com for more information) and "Net Zero Energy Buildings" (see:  www.NetZeroEnergyBuildings.com for more information).  Net Zero Energy Buildings generate as much (or more) energy than they use, and export their excess power to the grid.

Climate Change, Global Warming or Global Cooling?

The past 10 years indicates the opposite, that there has been a moderation of "global warming" and that global cooling has taken place. "Climate change" is always taking place, from one day to the next, and one week to the next, as well as one year to the next. Climate change is a dynamic process.  The REI would request that the researchers and scientists stay out of politics, and not be politicians, and that the politicians would stay out of the way of the scientists and researchers, and let them do their work, and that the politicians not pretend to be scientists.  

Everybody, scientists and politicians, just do your job so that we can come up with the scientific answers that form the basis of policy.

In the meantime, as there may still be 30 years of research before there are conclusive answers.  Can we "risk" 30 years of our children and our children's future, if there is a link between climate change and greenhouse gas emissions?

Simultaneously, there is a finite amount of petroleum, and many scientists and engineers believe we have well into Hubbert's "peak oil" analysis, that espouses that when 50% of domestic crude oil production has been reached, that there will be such significant upward demand on prices of the limited supplies of oil production, that the U.S. economy will experience severe economic, social, and political turmoil.

Hubbert's Peak Oil predictions were "right on" and this is validated as the U.S. in the early 1970's produced about 60% of its' oil demand and imported 40%.  That equation has flipped since then, because our domestic oil production has been on the decline since 1970, so now, due to our declining domestic oil production, we have to import 60% of our oil supplies, to meet our country's oil/energy demands.

How severe our economic calamity and next "oil shock" will depend upon a number of factors, including when this occurs, as well as the following:

1.  the dependence of the individual country upon its own crude oil production to meet its energy needs and to subsidize consumer imports; 

2.  the rate of relative decline in crude oil production; 

3.  the degree of difficulty encountered in replacing missing energy inputs; 

4.  the degree to which our country had prepared in advance for this inevitable geological and economic calamity.


Examples of past "oil shocks" and the economic and political calamities that followed: 


United States: Our peak crude oil production of domestic oil occurred in 1970; the first "oil shock" and oil crisis followed in 1973 with the Arab/OPEC Oil Embargo.

Iran: Their peak crude oil production occurred in 1974; They had their islamic revolution 1979 that overturned government and replaced it with radical islam.

Soviet Union: Their peak crude oil production was in 1989; what happened next? 
Their country disintegrated and the collapse of the Soviet Union followed in 1991. 

Indonesia: Their peak crude oil production was in 1991; their financial and government crisis followed in 1997.

Iraq: Iraq's crude oil production was in 1989; they then invaded Kuwait (for their oil) in 1991.

Using Mr. Hubbert's predictions, that beginning around 2000  we would see peak (global) oil production, then, if the country's not weaning themselves off of their oil addiction, and had not begun making the switch to renewable energy, that the negative economic and political calamities would soon follow, including ever-increasing prices of energy that is from fossil fuels. 

Now is the time to begin weaning ourselves off of fossil fuels and making the transition to and increasing the use of renewable energy.  

If you don't believe in climate change, or global warming, GREAT! Join us in the switch to renewable energy and a fossil-free economy! 

Believe in the fact that the United States is still "addicted" to foreign oil. Energy, and unfortunately, energy derived from fossil fuels is the very "lifeblood" of the American economy, as well as every industrialized country.  An economy dies without it's lifeblood of energy and oil. 

In 1973, the Arabs and OPEC brought the United States economy to a screeching halt during the OPEC Oil Embargo.  This, because they (mainly Saudi Arabia) disagreed with our foreign policy and why they "turned off the tap" of our need for their oil supplies, to keep our economy humming.  When they stopped the flow of oil to our country, they caused an "oil shock" that severely and negatively impacted our economy. 

In 1973, America was "addicted" to foreign oil to the amount of 40%.  

40% of our energy "requirements" that keep our economy alive, came from foreign oil and from countries that don't like us, or don't like our foreign policy.

Do people remember the gas shortages and long lines at their gas stations to get gas during the Arab Oil Embargo of 1973? 

Many people have forgotten that gas lines, people in their cars lined up and waiting for gasoline at their nearby gas station, with lines that were many blocks long.  And, after waiting 4-5 hours, and even overnight in many places, to finally take their turn to fill up their car with gasoline, that the gas station had run out of gas. 

That was 1973.  Today, our oil imports are no longer 40%, they are 60%.

America:  We do NOT have the luxury of time on our hands.  We need to end our dependence and reliance on foreign fossil fuels, especially from countries that don't like us! We need to rapidly begin expanding renewable energy technologies from our vast and abundant renewable energy resources, such as; solar, solar energy systems, solar cogeneration, solar trigeneration, "solar on every roof," waste to energy, waste to fuel, biomass gasification, B100 Biodiesel, Biomethane, Synthesis Gas, geothermal, E100 Ethanol (from sugar cane and NOT from corn), an wind where it makes economic sense.
