Wind farm
New installations place the U.S. on a trajectory to generate 20% of the nation’s electricity by 2030 from wind energy. Growth in 2008 channeled some $17 billion into the economy, positioning wind power as one of the leading sources of new power generation in the country, along with natural gas. Wind projects completed in 2008 accounted for about 42% of the entire new power-producing capacity added in the U.S. during the year.
United States wind energy policy
At the end of 2010, the installed capacity of wind power in the United States was just over 40,000 megawatts (MW), making it second in the world behind China. In 2010 Wind power accounted for 2.3% of the electricity generated in the United States. This amounted to 94,650 thousand megawatt-hours of electricity.
Driven by state renewable energy targets, fourteen states have installed over 1,000 MW of wind capacity, and a total of 37 states now have installed at least some utility-scale wind power. Texas, with 9,728 MW of capacity, has the most installed wind power capacity of any U.S. state, followed by Iowa with 3,670 MW. The Roscoe Wind Farm (780 MW) in Texas is the world's largest wind farm.
