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
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.
