Wind Energy

Wind energy is defined as the energy that is obtained from kinetic energy of the wind that moves across the earths’ surface. Wind then is converted into usable electrical energy in the wind turbine. The energy of motion (kinetic energy) of the air flow is an indirect form of solar energy and thus belongs to renewable energies. It is now almost exclusively utilized by wind turbines. A rotor is set in rotation by the air flow, which in turn drives a power generator using the rotary axis. The use of wind energy especially in coastal areas and in upland areas has risen steadily in recent years.
