Wind power - Wikipedia
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. This article deals only with wind power for electricity generation.
Wind turbine - Wikipedia
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. [1]
Wind power in the United States - Wikipedia
As of 2022, the United States has over 141 GW of installed wind power capacity. Wind power has increased dramatically over the past years. In 2010, however, newly installed generating capacity was about half of the previous year due to various factors, including the …
Wind power - Simple English Wikipedia, the free encyclopedia
Wind power is the conversion of the energy in wind into a more useful form of energy, like electricity. [2] It is a renewable source of energy that helps to cut down on the pollution of earth's air. Wind power capacity has expanded quickly to 336 GW in June 2014, and wind energy production was about 4% of total worldwide electricity usage, and ...
wind power - Encyclopedia Britannica
2024年11月6日 · wind power, form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. Together with solar power and hydroelectric power, wind power is one of the most widely utilized forms of renewable energy.
How Do Wind Turbines Work? | Department of Energy
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. When wind flows across the blade, the air pressure on one side of the blade decreases.
Wind Energy - MIT Climate Portal
2023年5月22日 · Wind energy is a form of renewable energy, typically powered by the movement of wind across enormous fan-shaped structures called wind turbines. Once built, these turbines create no climate-warming greenhouse gas emissions, making this a “carbon-free” energy source that can provide electricity without making climate change worse.
