Wind energy is one of the biggest source of renewable energy. In order to understand the working of the wind turbines, it is important to know about the different components of the wind turbine.

Although there are different types of wind turbines that operate, but the simplest possible wind-energy turbine consists of three major parts:

1. Rotor blades

The blades are the main part of the system. The blades act as barriers to the wind, although recent blade designs do more than just act as a barrier. As the wind forces the blades to move, the energy gets transferred to the rotor.

Electric generator is a device or machines that covert the mechanical energy into electrical energy. It’s based on the principal of electromagnetic induction that is scientific law, which was discovered by British scientist Michael Faraday and American scientist Joseph Henry in 1831.

According to this scientific principle an electric conductor such as copper wire moving through a magnetic field, electric current will flow through the conductor. The moving wire’s mechanical energy is converted into electrical energy. Faraday and Henry found that when a magnet is moved in a coil of wire, electric current is generated.

According to Faraday’s law of induction a moving magnetic field will cause electrons to move. Generators create electron movement in the copper wire coils contained within by moving them through a magnetic field.

Faraday was the one who built the first electromagnetic generator “Faraday disc”; it was a simple copper disc rotating between the poles of a horseshoe magnet. That generator produced a small DC voltage and large amounts of current that was inefficient, but that was good start for future generators.
