A Wind Generator Harnesses The Wind's Energy to Produce an Electric Current

A wind generator harnesses the wind's energy to produce an electric current. The generator works on the same principle as many of the other power generators we use. The concept is that an electromagnet creates a current when it is passed over a conductor. The magnets don't create electrons; they simply induce motion in the electrons themselves. This principle, called Faraday's law, is the foundation of nearly every generator built since its formulation in 1832. A wind generator is no different. It uses the wind to rotate a turbine. The blades of the generator are attached by gears to a coil, which is usually made of copper. The coil itself is wrapped around a magnet. When the turbine spins, the coil rotates around the magnet, which creates the current. That same principle of a turbine spinning a coil around a magnet is what is used in hydroelectric, nuclear, even fossil fuel based power plants. They all utilize steam or water as the medium for turning the turbine, which requires the application of a significant amount of heat. A wind generator, on the other hand, requires no intermediary forces. It converts the mechanical energy directly to electric energy. Source: hoosacwind.com
