OverviewWind power capacity and productionWind energy resourcesWind farmsEconomicsSmall-scale wind powerImpact on environment and landscapePolitics

In 2020, wind supplied almost 1600 TWh of electricity, which was over 5% of worldwide electrical generation and about 2% of energy consumption. With over 100 GW added during 2020, mostly in China, global installed wind power capacity reached more than 730 GW. But to help meet the Paris Agreement''s goals to limit climate change, analysts say it should expand much faster – by over 1%
