The U.S. land-based wind energy market installed nearly 14 GW of capacity in 2021. The leading states for land-based wind power projects in development at the end of 2021 were Texas (6,145 MW), Wyoming (3,000 MW), Illinois (just over 2,100 MW), and Oklahoma (1,748 MW). For offshore wind power, New York leads development on a capacity basis at 4,186 MW, followed by New Jersey with 3,758 MW, Massachusetts with 3,242 MW, and Virginia with 2,587 MW.
Wind power projects account for a significant portion of the clean energy currently under construction in the United States, with land-based wind accounting for 20% and offshore wind accounting for an additional 15%. The remaining projects are solar energy and battery storage.
On a per-project basis, wind facilities are growing in size. Of the land-based wind projects currently operating, 39% have between 100 and 200 MW of capacity. Most projects now in development—more than 70%—are set to have more than 200 MW of capacity. A survey of wind energy experts published in 2021 found expected costs to be 50% lower by 2050 than predicted in 2015.
General Electric wind turbines were the most commonly installed in 2021, making up half of the new land-based capacity. Vestas ranked second with 28% of new installations, followed by Nordex (12%) and Siemens Gamesa (10%).
