1500 gigawatts of wind power by 2020 and potentially much higher still

Faster and faster, renewable energy from wind power is becoming a means to global conservation. By 2020, 1500 Gigawatts of Wind energy capacity will be installed worldwide estimates Heinz Dahl of the World Wind Energy Association, and wind capacity could go much further than that still! Heinz also discusses the use of hydro and geothermal power to firm up wind power generation, and a new project in the U.S. where cost reductions in the energy coming out of the turbines is 40 per cent!
