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 . Turbines will shut down if the wind is too strong (approximately 55 miles per hour) to prevent damage to the equipment. [pdf]

The from wind power is minor when compared to that of . Wind turbines have some of the lowest : far less than for the average unit of electricity, so wind power helps limit climate change. Use of engineered wood may allow carbon negativ. It involves using wind turbines to convert the turning motion of blades, pushed by moving air (kinetic energy) into electrical energy (electricity).

requires that the mass of air entering and exiting a turbine must be equal. Likewise, the requires the energy given to the turbine from incoming wind to be equal to that of the combination of the energy in the outgoing wind and the energy converted to electrical energy. Since outgoing wind will still possess some kinetic energy, there must be a maximum proportion of the input energy that is available to be converted to electrical energy. Ac.

[FAQS about How to connect wind turbine generator to the power grid]
Wind turbine design is a careful balance of cost, energy output, and fatigue life. Wind turbines convert wind energy to electrical energy for distribution. Conventional horizontal axis turbines can be divided into three components: • The rotor, which is approximately 20% of the wind turbine cost, includes the blades for converting wind energy to low-speed rotational energy. .
Location is critical to the overall success of a wind farm. Additional conditions contributing to a successful wind farm location include: wind conditions, access to electric transmission, physical access, and local electricity prices. The faster the average wind speed, the more electricity the wind turbine will generate, so faster winds are generally economically better for wind farm deve. [pdf]
