  • nacelle - with average dimensions of 10 m (length) x 3 m (height) x 3 m (width) with the power generator inside. The nacelle is placed on the top of the tower, it adjusts its position to the wind direction
  • rotor - rotor of a typical wind turbine consists of three blades, usually made of fiberglass or carbon fiber, it's diameter is in the range 40-100 m
