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 the United States
In 2016 Texas surpassed the 20,000 MW mark by adding over 1800 MW of generating capacity. In 2011, Texas had become the first state to surpass the 10,000 MW mark.
In July 2008, Texas approved a $4.93 billion expansion of the state's electric grid to bring wind energy to its major cities from western areas of the state. Transmission companies will recoup the cost of constructing the new power lines, expected to be completed in 2013, from fees estimated at $4 per month for residential customers. A lack of transmission capacity forced wind turbines to be shut down at times and reduced wind power generation in Texas by 17% in 2009.
