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
Many of the new technologies that harness renewables — including wind, solar, geothermal, and biofuels — are, or soon will be, economically competitive with the fossil fuels that meet 85% of United States energy needs. 
Dynamic growth rates are driving down costs and spurring rapid advances in technologies. 
Wind power and solar power are becoming increasingly important relative to the older and more established hydroelectric power source. 
By 2016 wind power covered 37.23% of total renewable electricity production against 43.62 % for hydroelectric power. 
The remaining share of power was generated by biomass at 10.27%, solar power at 6.03% and geothermal with 2.86 % of total renewable generation.
