Wind power has grown significantly in the past 30 years. Advances in wind energy technology have decreased the cost of wind electricity generation. Government requirements and financial incentives for renewable energy in the United States and in other countries have also contributed to growth in wind power.
In fact, total annual U.S. electricity generation from wind energy increased from about 6 billion kilowatt-hours (kWh) in 2000 to about 380 billion kWh in 2021. In 2022, wind turbines were the source of more than 10 percent of total U.S. utility-scale electricity generation.
