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 China
In 2016, China added 19.3 GW of wind power generation capacity to reach a total capacity of 149 GW, and generated 241 TWh of electricity, representing 4% of total national electricity consumption. 
Both China's installed capacity and new capacity in 2015 are the largest in the world by a wide margin, with the next largest market, the United States, adding 8.6 GW in 2015 and having an installed capacity of 74.4 GW. 
Wind power in the United States has however a much higher capacity factor.
