Utility-Scale Wind Energy
Wind is an important source of affordable, renewable energy, contributing 8% of the nation's electricity supply in 2020. U.S. wind power capacity grew at a record pace in 2020, with $25 billion invested in 16.8 gigawatts of capacity.
Utility-scale turbines are usually defined as turbines that exceed 100 kilowatts in size. Utility-scale wind turbines are typically installed in large, multi-turbine wind farms connected to the nation's transmission system. More information is available on the Energy Department's wind energy research portfolio.
There are more than 65,000 land-based wind turbines operating across 43 states, Guam, and Puerto Rico. These turbines represent more than 105 gigawatts of energy capacity. To optimize wind project cost and performance, turbines continue to grow in size. The average rated (nameplate) capacity of newly installed wind turbines in the United States in 2019 was 2.55 MW.
Offshore wind energy is a burgeoning industry in the United States. America's first offshore wind farm—located in Rhode Island, off the coast of Block Island—powered up on December 12, 2016. The U.S. offshore wind project pipeline has reached a total of 35,324 megawatts of capacity, including the 30-MW Block Island Wind Farm and the 12-MW Coastal Virginia Offshore Wind pilot project.

This report describes the potential development of wind energy through 2050 and provides an overview of the current wind market, expected impacts if 35% of the nation's electric generation comes from wind power, and a proposed outline of activities that will be required to make the vision a reality.
Enabling Wind Power Nationwide
This report describes the impact of the changes in wind turbine technology, mostly through the use of taller towers and larger wind turbine blades. Technological advancements have expanded areas in which wind can be economically developed and enabled every state in the nation to have utility-scale wind potential.
