2. About Wind turbineIt is a machine that converts movement from wind toelectricity. 3. LocationIt should be located in a clear area where wind isusually heavy. 4. BladesThe speed of the wind is the main factor to move theblades, witch convert it to electricity 5. GeneratorsThe wind and the blades are the main factor to get thegenerator working. 6. Transmission systemIts the system that controls the movement of the blades tomake it constant. 7. ReferencesSiemens, Energy efficiency in the Middle East.
