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%

OverviewHistoryWind power densityEfficiencyTypesDesign and constructionTechnologyWind turbines on public display
The windwheel of Hero of Alexandria (10–70 CE) marks one of the first recorded instances of wind powering a machine. However, the first known practical wind power plants were built in Sistan, an Eastern province of Persia (now Iran), from the 7th century. These "Panemone" were vertical axle windmills, which had long vertical drive shafts with rectangular blades. Made of six to twelve sails covered
6 FAQs about [Power generation of wind turbine]
What is a wind turbine?
The term windmill, which typically refers to the conversion of wind energy into power for milling or pumping, is sometimes used to describe a wind turbine. However, the term wind turbine is widely used in mainstream references to renewable energy (see also wind power).
How many kilowatthours do wind turbines generate a year?
Total annual U.S. electricity generation from wind energy increased from about 6 billion kilowatthours (kWh) in 2000 to about 434 billion kWh in 2022. In 2022, wind turbines were the source of about 10.3% of total U.S. utility-scale electricity generation.
How does a wind turbine turn mechanical power into electricity?
This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
What is wind turbine design?
Arrays of large turbines, known as wind farms, have become an increasingly important source of renewable energy and are used in many countries as part of a strategy to reduce their reliance on fossil fuels. Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind.
How do wind turbines work?
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. To see how a wind turbine works, click on the image for a demonstration.
What percentage of electricity is generated by wind turbines?
In 2022, wind turbines were the source of about 10.3% of total U.S. utility-scale electricity generation. Utility scale includes facilities with at least one megawatt (1,000 kilowatts) of electricity generation capacity.
