Wind farm
New installations place the U.S. on a trajectory to generate 20% of the nation’s electricity by 2030 from wind energy. Growth in 2008 channeled some $17 billion into the economy, positioning wind power as one of the leading sources of new power generation in the country, along with natural gas. Wind projects completed in 2008 accounted for about 42% of the entire new power-producing capacity added in the U.S. during the year.
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).
