American Wind Energy Association - August 14, 2006

U.S. wind energy installations now exceed 10,000 megawatts (MW) in generating capacity, and produce enough electricity on a typical day to power the equivalent of over 2.5 million homes, the American Wind Energy Association (AWEA) announced today. A megawatt of wind power generates enough to serve 250 to 300 average homes.

“Wind energy is providing new electricity supplies that work for our country’s economy, environment, and energy security,” said AWEA Executive Director Randall Swisher. “With its current performance, wind energy is demonstrating that it could rapidly become an important part of the nation’s power portfolio.”

The record growth in wind power is driven by demand for the popular energy source and concerns over fuel price volatility and supply. It was also made possible by a timely renewal of the production tax credit (PTC), a federal incentive extended in the Energy Policy Act signed a year ago by President Bush. Previously, the credit had been allowed to expire three times in seven years, and this uncertainty discouraged investment in wind turbine manufacturing in the country. AWEA is calling for a long-term extension of the PTC before its scheduled expiration at the end of 2007 to avoid further “on-again-off-again”cycles and encourage long-term investment.

The industry is gaining momentum as it grows. The first commercial wind farms were constructed in California in the early 1980s, and after reaching 1,000 MW in 1985, it took more than a decade for wind to reach the 2,000-MW mark, in 1999. Since then, however, installed capacity has grown fivefold (for a chart showing historical cumulative capacity, see http://www.awea.org/faq/instcap.html). Today, the industry is installing more wind power in a single year (3,000 MW expected in 2006) than the amount operating in the entire country in 2000 (2,500 MW).

As the U.S. wind energy industry sails past the 10,000-megawatt mark, AWEA released the following figures and statistics to illustrate some of the economic, environmental, and energy security benefits of wind power development.

Economic benefits:

• Supplying electricity: Wind was the second-largest source of new power generation in the country in 2005 after natural gas, and is likely be so again in 2006, according to the Energy Information Administration.
• Creating jobs: Wind turbine manufacturing companies have recently opened facilities in Iowa (Clipper Windpower), Minnesota (Suzlon), and Pennsylvania (Gamesa), and wind turbine orders are creating jobs all the way down the supply chain, sometimes in areas that do not have a large wind resource, such as Louisiana.

Environmental benefits:

• Less global warming pollution: Today’s 10,000 MW of wind power are keeping 16 million tons of carbon dioxide (CO 2), the leading greenhouse gas associated with global warming, out of the air EVERY YEAR. That’s equivalent to the amount of CO 2 that would be absorbed by over 9,000 square miles of forest, an area about the size of Vermont.
• Better air quality: If the same amount of electricity as that generated by America’s 10,000-MW wind turbine fleet were instead produced using the average utility fuel mix, it would emit 73,000 tons of sulfur dioxide and 27,000 tons of nitrogen oxide per year, as well as other pollutants such as mercury.

Energy security benefits:

• Saving fuel: Today’s 10,000 MW of wind power saves about 0.6 billion cubic feet per day (bcf/day), or about 3.5% of the natural gas used nationwide to generate electricity.
• Domestic, inexhaustible energy source: America’s wind resource potential is vast--theoretically more than twice enough to meet current U.S. electricity supply. President Bush said earlier this year that wind could meet 20% of the country’s electricity supply (the share that nuclear power provides today).

AWEA, formed in 1974, is the national trade association of the U.S. wind energy industry. The association's membership includes turbine manufacturers, wind project developers, utilities, academicians, and interested individuals.
