Definition of Wind Energy “Wind Energy - Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans‚ earth‚ and atmosphere by the sun. Turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this
