Wind power is the conversion of wind energy into more useful forms, usually electricity, using wind turbines. At the end of 2006, worldwide capacity of wind-powered generators was 74,223megawatts; although it currently produces just over 1% of world-wide electricity use. it accounts for approximately 20% of electricity use in Denmark, 9% in Spain, and 7% in Germany.Globally, wind power generation more than quadrupled between 2000 and 2006.
Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology), wind energy is used to turn mechanical machinery to do physical work, such as crushing grain or pumping water.
Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and green house emmission if used to replace fossil-fuel-derived electricity. The intermittency of wind seldom creates problems when using wind power at low to moderate penetration levels.
India ranks 4th in the world with a total wind power capacity of 6,270 MW in 2006. Wind power generates 3% of all electricity produced in India. The World Wind Energy Conference in New Delhi in November 2006 has given additional impetus to the Indian wind industry. The windfarm near Muppandal, India, provides an impoverished village with energy for work.India-based Suzlon Energy is one of the world's largest wind turbine manufacturers.
