Q&A - We answer some questions on Renewable Energy Credits
- According to a poll by Deloitte (a big auditing and consulting firm) 54% of Americans say they would pay more for Alternative Energy Resources.
- At over 6.5 billion tons annually, the U.S. is the world’s largest source of CO2 emissions (World Bank Little Green Data Book). The U.S. also leads in annual CO2 emissions per person (22 tons) for countries with a population over 5,000,000 (Wikipedia).
- Industry experts predict that, with proper development, wind energy could provide 20% of this nation's energy needs (U.S. Dept of Energy Renewable Energy Laboratory). Compare this to less than 1% right now. This would mean generating about 650 Million MWh from wind annually, or more than 500 Million MWh over current projections.
This means reducing (compared with our current energy mix):
- Over 350 Million tons of CO2 emissions every year (a 5% reduction)
- Over 120 million tons of coal consumption
- Over 750 billion cubic feet of natural gas consumption
- Over 20 million barrels of oil consumption
- Last year, the U.S. imported 3.7 billion barrels of oil, and 3.4 trillion cubic feet of gas (Energy Information Administration). At current prices (as of October 2, 2007), this represents over $300,000,000,000 dollars sent out of the U.S., which accounts for roughly 40% of the U.S. trade deficit (based on estimated $760 billion deficit in 2006 – Bureau of Economic Analysis).
- Facts About NOx (U.S. EPA) :
- "Nitrogen oxides, or NOx, is the generic term for a group of highly reactive gases, all of which contain nitrogen and oxygen in varying amounts. Many of the nitrogen oxides are colorless and odorless. However, one common pollutant, nitrogen dioxide (NO2) along with particles in the air can often be seen as a reddish-brown layer over many urban areas.
The primary manmade sources of NOx are motor vehicles, electric utilities, and other industrial, commercial, and residential sources that burn fossil fuels. NOx can also be formed naturally, and:
- is one of the main ingredients involved in the formation of ground-level ozone, which can trigger serious respiratory problems
- reacts to form nitrate particles, acid aerosols, as well as NO2, which also cause respiratory problems
- contributes to formation of acid rain
- contributes to nutrient overload that deteriorates water quality
- contributes to atmospheric particles, that cause visibility impairment most noticeable in national parks
- reacts to form toxic chemicals
- contributes to global warming"
Facts About Soot (fine particulate matter, PM2.5, etc. – from U.S. EPA):
"'Particulate matter', also known as particle pollution or PM, is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles.
These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.
Numerous scientific studies have linked particle pollution exposure to a variety of problems, including:
- increased respiratory symptoms, such as irritation of the airways, coughing, or difficulty breathing, for example;
- decreased lung function;
- aggravated asthma;
- development of chronic bronchitis;
- irregular heartbeat;
- nonfatal heart attacks; and
- premature death in people with heart or lung disease."
Facts About Mercury Emissions (U.S. EPA):
Coal-burning power plants are the largest human-caused source of mercury emissions to the air in the United States, accounting for over 40 percent of all domestic human-caused mercury emissions.
Mercury exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system of people of all ages.
It has been demonstrated that high levels of methylmercury in the bloodstream of unborn babies and young children may harm the developing nervous system, making the child less able to think and learn.
Fish and shellfish are the main sources of methylmercury exposure to humans. Fish advisories are also issued for men, women, and children of all ages when appropriate.

Q: If REC sales go to projects that are running anyway, how do they help promote new resources?
The objective of the market for RECs is to create a market for Renewable that supplements the market for Energy, so that producers (current, future, potential) can attribute some benefit (in the form of cash) to going through the extra effort of producing Renewable Energy. This allows them to see Renewable as a product, one that – with enough demand in the marketplace – they can sell profitably. And if there’s one thing that’s been proven in a free market system like ours, it’s that producers will always respond to strong market demand for profitable products.
By creating a market for RECs, we create demand for Renewable Energy, so that producers see a strong profitable market for this good. New supplies will naturally follow (there is evidence this is happening already – there are many wind projects being planned right now throughout the country).
Q: If RECs provide only a small portion of renewable project revenue, are they really a boost to these projects?
This is why we’re in the business - our goal is to make Renewable a high-volume, high-value product in its own right, a product that satisfies the need for substantial incentives to producers and the need for consumers to express their preference for Renewable and all that it represents, rather than just an occasional, low value add-on to Energy.
