As wind installations continue across the country and offshore wind projects move beyond the planning process, technology costs and wind energy prices continue to fall. These trends and more are detailed in three market reports released by the U.S. Department of Energy:
Wind Technologies Market Report
In 2017, wind energy contributed 6.3% of the nation's electricity supply. In 14 states, it contributed 10% of total electricity generation—and more than 30% in four of those states.
The average capacity of newly installed wind turbines in the United States in 2017 was 2.32 MW, up 8% from the previous year and 224% since 1998–1999. Bigger turbines with longer blades are enhancing wind plant performance. Wind projects built in the past few years have seen capacity factors—a measure of how close a plant is operating to its maximum output—increase by 79% compared to projects that were installed from 1998 to 2001. And after topping out at 7¢/kWh in 2009, the average levelized long-term price from wind power sales agreements has dropped to around 2¢/kWh.

Distributed Wind Market Report
In total, U.S. wind turbines in distributed applications reached a cumulative installed capacity of 1,076 MW—which came from roughly 81,000 turbines installed across all 50 states, Puerto Rico, the U.S. Virgin Islands, and Guam.
Thirty-five percent of distributed wind projects installed in 2017 were at homes and 25% were agricultural installations. U.S.-based small wind turbine manufacturers accounted for more than $226 million in export sales between 2015 and 2017.

Offshore Wind Technologies Market Update
The U.S. offshore wind industry took a leap forward as several commercial-scale projects were selected for state-issued power purchase awards in 2018, while other U.S. states have implemented dedicated procurement and offtake policies during 2017–2018. The U.S. offshore wind development pipeline contains more than 25,000 MW of potential capacity across 13 states.
Researchers are evaluating floating substructure configurations to overcome the significant challenge of building offshore wind turbines in deep waters, where roughly 60% of the U.S. offshore wind resource lies.
