Wind power in the United States
The 2011 NREL report, "Large-Scale Offshore Wind Power in the United States", analyzes the current state of the offshore wind energy industry. According to the report, offshore wind resource development would help the country to achieve 20% of its electric power from wind by 2030 and to revitalize the manufacturing sector. Offshore wind could supply 54 gigawatts of capacity to the nation's electrical grid, thereby increasing energy security. It could also generate an estimated $200 billion in new economic activity and create thousands of permanent jobs. NREL’s report concludes that "the development of the nation’s offshore wind resources can provide many potential benefits, and that offshore wind energy could play a vital role in future U.S. energy markets".
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).
