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.
Renewable energy in the United States
Renewable energy accounted for 14.94% of the domestically produced electricity in 2016 in the United States. 
This proportion has grown from just 7.7% in 2001, although the trend is sometimes obscured by large yearly variations in hydroelectric power generation. 
Most of the growth since 2001 can be seen in the expansion of wind generated power, and more recently, in the growth in solar generated power.
Renewable energy in California is prominent, with around 29% of electricity coming from RPS-eligible renewable sources (including hydropower).
