Wind turbines are becoming cheaper and more efficient, bringing down the cost of electricity. Europe is at the hub of this young and high-tech industry.
Wind turbines produce electricity by using the natural power of the wind to drive a generator.
The wind is a clean and sustainable fuel source. It does not create pollution and it will never run out. The need for clean energy Conventional methods of generating electricity burn fuel to provide the energy to drive a generator, usually by using the heat to provide steam to drive a turbine. How wind turbines work Almost all wind turbines producing electricity consist of rotor blades which rotate around a horizontal hub. The hub is connected to a gearbox and generator, which are located inside the nacelle.
