Wind supplies 57% of Denmark''s electricity generation and over 20% in ten other countries. 7 Global wind additions reached a record 117 GW in 2023. 7 In 2024, onshore installations surpassed 100 GW

Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity.

Modern commercial wind turbines produce electricity by using rotational energy to drive an electrical generator. They are made up of one or more blades attached to a rotor and an

Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator,

In 2024, wind supplied over 2,494 TWh of electricity, which was 8.1% of world electricity. To help meet the Paris Agreement''s goals to limit climate change, analysts say it should expand much faster than it currently is – by over 1% of electricity generation per year. Expansion of wind power is being hindered by fossil fuel subsidies

To truly understand how wind turbines generate power—from the movement of their blades to the delivery of electricity into the grid—it is essential to explore every stage of the process,

Wind turbine capacity is ever evolving, but today, most onshore wind turbines have a capacity of 2–3 megawatts (MW), producing around 6 million kilowatts hours (kWh) of electricity

Energy harnessed by wind turbines is variable, and is not a "dispatchable" source of power; its availability is based on whether the wind is blowing, not whether electricity is needed.

In an ideal world, a turbine would convert 100 percent of wind passing through the blades into power. Because of factors such as friction, these machines only have efficiency ratings of

Every year, wind turbines produce about 434 billion kilowatts (kWh) of electricity a year. Just 26 kWh of energy can power an entire home for a day. Wind is the third largest source of
