Transmission lines can then deliver the wind-generated electricity from prime windenergy areas, like the Great Plains, to various locations.In fact, just 15 percent of the land on Earth has enough wind speed capacity to meetglobal energy needs many times over. Consequently, U.S. energy policy calls for 20 percent ofthe nations total energy use to come from wind power by 2030, which is a modest proposal inlight of its impressive potential.A wind farm is a group of wind turbines in the same location used for produ
