And while each of those alternatives holds marked environmental advantages over dirty oil and coal, none match wind power's squeaky clean performance. The debate still continues whether or not wind power is green: there are those that believe it is and have valid arguments to support their claim while others discount it as being green and have their arguments as well.Is wind powergreenIn a nutshell, wind power systems consist of tall, free-standing turbines that convert moving air into usable electricity. As wind pushes the turbine blades around, the spinning motion turns the turbine rotor, which then drives the shaft of an electric generator housed within the turbine. Transmission lines can then deliver the wind-generated electricity from prime wind energy areas, like the Great Plains, to various locations.In fact, just 15 percent of the land on Earth has enough wind speed capacity to meet global energy needs many times over. Consequently, U.S. energy policy calls for 20 percent of the nation's total energy use to come from wind power by 2030, which is a modest proposal in light of its impressive potential.The actual ground space required for such a project is less than 2 square kilometers.That doesn't i
