Wind Energy

Wind energy (also called wind power) is a form of alternative and renewable energy harvesting via the translation of the kinetic power of moving air masses into electrical current. Wind is a natural phenomenon that occurs globally as air moves across the surface of Earth in response to differences in atmospheric pressure and density, which is the result of the interaction of differential solar heating of Earth's topographic features.

The translation of the power inherent in wind dates deep into antiquity. The movement of wind over a sail to create dynamic pressure differences provides thrust for sailing ships and, over the course of human history, has fueled exploration. Wind, usually by a form of windmill, has been used to pump...
