Wind Power is the fastest growing source of electrical energy in the world today. Wind power involves the conversion of wind into a useful form of energy by using turbines to produce electricity. Wind farms may consist of many individual turbines connected to an electric power transmission network, and large wind farms dominate this trend. Offshore wind is steadier and stronger than wind on land, but their construction and maintenance are considerably more expensive. Small wind farms on land provide electricity to isolated locations. Utility companies are increasingly buying the surplus electricity produced by wind. On site wind energy and ‘community wind power’ involve one or a few wind turbines feeding the local distribution system. This type of installation thrives in areas with favorable policy and can be a great way to offset industrial electrical use or provide another source of revenue for farm or forest land.
