On March 29 in the United States, power generated by wind turbines was the second-highest source of electricity for that day. It was the first time in U.S. history that wind turbines outperformed nuclear and coal power. The wind turbines generated more than 2,000 gigawatt-hours of electricity, more energy generated than by nuclear and coal power plants. Electricity from wind power has gone up from roughly 6 billion kilowatt-hours in 2000 to 380 billion in 2021, with wind turbines accounting for about 9.2% of the total "utility-scale electricity generation" in the U.S. In 2020, 42% of new electricity generation capacity came from land-based wind energy.
