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.
Wind power
In 2017, global wind power capacity expanded 10% to 539 GW.. Yearly wind energy production grew 17% reaching 4.4% of worldwide electric power usage, and providing 11.6% of the electricity in the European Union.
Denmark is the country with the highest penetration of wind power, with 43.4% of its consumed electricity from wind in 2017.
At least 83 other countries around the world are using wind power to supply their electric power grids.
