Wind power is the use of energy to generate useful work. Historically, wind power was used by , and , but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with , generally grouped into and connected to the .

The London Array is a 175-turbine 630 MW located 20 kilometres (12 mi) off the coast in the outer in the United Kingdom. It was the in the world until reached full production in September 2018. Construction of phase 1 of the wind farm began in March 2011 and was comp. . 海上风力发电(Offshore wind power),又称海上风力能源,是于海上建设,通常设置地点位于,利用进行发电。一般而言,海上风力资源较陆上丰富,且风向较为稳定,使得海上风力发电较陆上风力发电在同样时间内能提供更多的电力 ,且设施远离民众居住地,各界对此类的反弹也较小。

The ratio between the speed and the wind speed is called . High efficiency 3-blade-turbines have tip speed/wind speed ratios of 6 to 7. Wind turbines spin at varying speeds (a consequence of their generator design). Use of and has contributed to low , which means that newer wind turbines can accelerate quickly if the winds pic.

*LCOE estimates for nuclear power from Lazard are "based on the then-estimated costs of the and US-focused". In 2023, Bank of America conducted a LCOE study in which it postulated that existing LCOE estimates for renewables do not account for fossil fuel or battery backup and therefore levelized full system cost of electricity (LFSCOE) would.

A wind farm is a group of in the same location. A large wind farm may consist of several hundred individual wind turbines distributed over an extended area. The land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore. Almost all large wind turbines have the same design — a horizontal axis wind turbine having an up.

A wind turbine is a device that the of into . As of 2020 , hundreds of thousands of , in installations known as , were generating over 650 of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent , and are used in many countries to lower energ.

The Savonius turbine is one of the simplest turbines. , it is a -type device, consisting of two or three scoops. Looking down on the rotor from above, a two-scoop machine might resemble the letter "S" in . Because of the , the scoops experience less drag when moving against the wind than when moving with the wind. The differential drag causes the Sa.

Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. They can also include blades or be bladeless. Household-size vertical designs produce less power and are less common. Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwi.

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

An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the that supply the power, the that carries the power from the generating c. . 電力系統是一個由電力元件組成的網路,用來發電、輸電、用電。舉例來說,電力系統就是提供一個區域家庭用電及工業用電的網路,如果這個區域很大,那麼這個電力系統可以稱之為,並且可以區分為三個部份:,,。
