Wind is the most promising and fastest growing renewable energy source. Wind turbines worth $23 billion were installed in 2006 alone, leading to an increase of 2454 MW capacity in US, 2233 MW in Germany, 1,840 MW in India, 1,587 MW in Spain, 1,347 MW in China and 810 MW in France. At the end of 2006, worldwide capacity of wind-powered generators was 74,223 megawatts (was only 2500 MW in 1992). Globally, wind power generation quadrupled between 2000 and 2006. It already accounts for approximately 18% of electricity in Denmark, 9% in Spain, and 7% in Germany.
