Wind energy is the energy contained of force of wind that beat on the earth surface. Exploited, it can be transformed in mechanical energy for pumping water, for example, or grinding wheat, mill which works using wind. By connecting a rotor to a power generator, modern wind turbines convert wind energy, which spin the rotor, in electricity. Wind energy is generated through transfer of wind energy to a wind turbine. Winds up due to heating uneven surface of the Earth, from energy radiated by the Sun, reaching the surface of our planet. To an efficiency of a turbine contribute size of blade and type converter from axial movement in electricity. Wind turbines are called and wind generators, wind energy converter (wind energy converter - WEC) or wind power unit (WPU). The power generated by wind turbine is directly proportional with air density, covered area a complete motion of rotor palettes and the square of wind speed. The wind passing through the propeller blade is slowed down and spread.

Compunerea sistemului: 1.Blades - Their shape and design is essential to provide the necessary force rotation. This design is own each type of power generator. 2. Nacelle - Contains electrical generator providing a mechanical protection 3. Tower - Provides support structure and resistance of the superior ensemble 4. Footing ensure mechanical resistance of wind generator

Egyptians may have been first who have used the energy generated by wind when they navigated on the Nile upstream, around the IV century B.C., followed by many others, including Christopher Columbus when he discovered America in 1492, being propelled by the wind.
Wind energy has been exploited overland when the first wind mill was built [...]
