The U.S. wind energy industry installed 5,244 megawatts (MW) in 2007, expanding the nation's total wind power generating capacity by 45 percent in a single calendar year and injecting an investment of over $9 billion into the economy, the American Wind Energy Association (AWEA) has announced. The new wind projects account for about 30 percent of the entire new power-producing capacity added nationally in 2007.

"This remarkable and accelerating growth is driven by strong demand, favorable economics, and a period of welcome relief from the on-again, off-again, boom-and-bust, cycle of the federal production tax credit (PTC) for wind power." --Randall Swisher, Executive Director, AWEA
