U.S. wind industry reports enduring growth in first quarter of 2011
States continue to lead nation with clear, strong policies

Washington, D.C., April 28, 2011—America's wind power industry installed 1,100 MW of new capacity in
the first quarter of 2011 alone and entered the second quarter with another 5,600 MW under construction,
the American Wind Energy Association (AWEA) reported today. The under-construction figure is nearly
twice the megawatts that the industry reported at this time in both 2009 and 2010; moreover, two-thirds of
those megawatts are already locked in under long-term power purchase agreements with electric utilities,
indicating an enduring industry that has proven both nimble and strong through a range of economic and
policy conditions. The total wind fleet now stands at 41,400 MW—producing enough clean energy to
supply 10 million American homes.
"American wind energy is ramping up, and these first-quarter figures indicate an industry poised for a
renaissance. Refined technologies, affordable prices, and continued demand for clean, homegrown
energy—these are all reasons why wind has consistently posted strong growth numbers, adding 35% of
all new generating capacity since 2007," said Denise Bode, AWEA CEO. "In an economy in which gas

prices have hit $4 a gallon and are still on the rise, America must implement long-term energy policies
centered on homegrown sources. And wind delivers. By powering our electric cars using wind, Americans
can pay the equivalent of 70 cents a gallon at the pump."

The first quarter's 1,100 MW of new capacity came online in 12 different states, with some seeing double-
digit growth. U.S. states with the most capacity additions so far include: Minnesota (293 MW), Illinois (240
MW), Washington (151 MW), Idaho (119 MW), and Nebraska (81 MW).
