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 Alaska
In early 2010, the National Renewable Energy Laboratory released the first comprehensive update of wind energy potential by state since 1993, showing that Alaska has the potential to install 494,700 MW of wind power, capable of generating 1,620,000 million kWh/year. Alaska used 6,291 million kWh in 2011.
