Wind power has mainly advantages and is more and more popular. What else you should know about it?

Wind energy is one of natural energy sources. Have you ever wondered on how such energy is created? Basically, energy is acquired by means of certain turbines. These turbines change mechanical energy into electricity. Nonetheless, it is necessary to keep in mind that wind turbines could produce electricity only where the wind blows. Furthermore, the speed of wind needs to be greater than “start speed”. Alternatively, turbines remain stationary and the energy is not produced.
