Electricity generation with wind
In 2020, wind turbines in the United States were the source of about 8.8% of total U.S. utility-scale electricity generation with about 23 (GW) —more than any other renewable electricity generation source.
Texas has the most wind turbine capacity among states (29.1 GW installed as of August 2020). Project developers in Texas expect to add another 4.0 GW by the end of the year, based on reported online dates. Project developers plan to add 2.7 GW in Oklahoma, increasing the state’s wind capacity from 8.2 GW to 10.9 GW.
New technologies have decreased the cost of producing electricity from wind, and growth in wind power has been encouraged by government and industry incentives.
There are three basic types of wind turbines:
The size of wind turbines varies widely. The length of the blades is the biggest factor in determining the amount of electricity a wind turbine can generate. Small wind turbines that can power a single home may have an electricity generating capacity of 10 kilowatts (kW). The largest wind turbines in operation have electricity generating capacities of up to 10,000 kW, and larger turbines are in development. Large turbines are often grouped together to create wind power plants, or wind farms, that provide power to electricity grids.
