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.
Hydroelectric power in the United States
Hydroelectric power stations in the United States are currently the largest renewable source of energy, but the second for nominal capacity (behind Wind power in the United States). Hydroelectric power produced 35% of the total renewable electricity in the U.S. in 2015, and 6.1% of the total U.S. electricity.
