Wind is the most promising renewable energy source. Wind turbines are a source of renewable energy. No matter how much energy we collect and use from the wind, there is still more available.
The basic concept of wind turbine is converting kinetic energy of wind into mechanical energy and then this mechanical energy into electrical energy.
Firstly, the force of the wind is caught by the turbine's blades and causes them to rotate. This motion spins the shaft of the turbine and results in mechanical energy. Then, the mechanical energy that drives the generator is converted into electrical energy.
