Offshore wind holds huge promise as a renewable electricity source. Using existing turbine technologies, the U.S. potential is 2,058,000 megawatts (MW), enough to generate double the electricity demand of the entire United States in 2015. About 80 percent of that electricity demand is along the coasts, so getting the power to the public could prove easier than transmitting it from wind-rich midwestern states. Utilities from eight states up and down the East Coast from Maine to Virginia have committed to procuring 22,500 MW of offshore wind so far, and wind power appeared poised to take off when the Department of the Interior awarded 11 commercial offshore leases in 2016.
