Wind is being used as the source of energy for over 5000 years in sailing the ships. It is a clean and inexhaustible source of energy. It is estimated that over 70 TW of wind power can be commercially viable which is much greater than the average total power consumption of the human world that was 15 TW in 2004 [Wikipedia, 2009].

The winds are produced as the Earth is unevenly heated by the Sun. The sunlight falls normally on the equator so it receives more heat than any other parts of the Earth, whereas poles receiving least amount of heat. Also, the sea is cooler than land in the day times generally causing the wind to flow from sea towards land. Reverse is happened at night. This uneven heating gives rise to convection currents and the air flows.
