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
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.
