United States wind energy policy
There are currently 5,600 MW of projects under construction in 2011. The U.S. Department of Energy's 2011 report "20% Wind Energy by 2030" envisioned that wind power could supply 20% of all U.S. electricity, which included a contribution of 4% from offshore wind power.
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).
