Energy policy of the United States
U.S. wind power installed capacity now exceeds 65,000MW. For calendar year 2014, the electricity produced from wind power in the United States amounted to 181.79 terawatt-hours, or 4.44% of all generated electrical energy. Texas is firmly established as the leader in wind power development, followed by Iowa and California.
Wind power in Ohio
On February 11, 2010, the National Renewable Energy Laboratory released the first comprehensive update of the wind energy potential by state since 1993, showing that Ohio had potential to install 55 GW of onshore wind power nameplate capacity, generating 152 TWh annually. For comparison, Ohio consumed 160.176 TWh of electricity in 2005; the entire U.S. wind power industry was producing at an annual rate of approximately 50 TWh at the end of 2008; and Three Gorges Dam (the world's largest electricity-generating station) produced an average of 80 TWh/yr in 2008 and 2009.
