It is necessary to use a wind turbine for utilizing the kinetic energy of the wind and convert it into electrical energy, Wind turbines are basically 80 to 120-meter-high based on the strength of the wind. In order to obtain this energy in large quantities, wind turbines must be set up in places where windy conditions are predominant.

The wind turbines have to be oriented in the direction of the wind, which is done by means of a vane on the nacelle. From there, the force of the air currents will set the three main parts of the wind turbine in motion:

The rotor: It is composed of three blades and the bushing which joins them together. It captures the force of the wind and convert it into mechanical rotational energy.

The multiplier: It is connected to the engine by means of a shaft. It increases the rotational speed from 30 revolutions per minute (rpm) to 1500 rpm.

The generator: It converts the mechanical energy of rotation into electrical energy.

Wind turbines of a wind farm are connected together by underground cables which carry the electricity to a transformer substation.
