A wind turbine is a device that, using blade rotors, produces electric power from the wind power. The concept is formed with the compositional element aero- (referring to "air") and the term generator (a machine that generates energy or force).
Before proceeding with the definition of a wind turbine, it is important to clarify some ideas. The wind power is obtained from wind, since the Kinetic energy associated with the movement of air masses. The electric power, meanwhile, is the energy resulting from the potential difference between two points.
Returning to the notion of a wind turbine, this type of device manages to convert wind energy into electrical energy. For this he uses blade rotors: that is, a rotating system that, when influenced by the wind, enables the movement of the blades.
When the wind turbine blades move, the kinetic energy comes into action, which is transformed into mechanical energy and then, by means of a alternator, in electrical energy. In other words: the kinetic energy of the moving air (wind energy) provides mechanical energy to the blade rotors and, thanks to a transmission mechanism, the alternator is rotated, which produces electrical energy from mechanical energy. rotational.
There are the horizontal axis wind turbines and the vertical axis wind turbines. It is common for wind turbines to be grouped into wind farms and that the electrical energy they produce is supplied to the electrical network. It is worth mentioning that its operation does not require combustion that causes gases of greenhouse effect.
