Wind Power Can Produce 50% Of Global Energy Needs

The article, (via Mark Thoma) reports on a study at Stanford and the University of Delaware on the use of wind power.  The study found that the upper limit on the use of wind power was much higher than had been previously believed.  The limit was based upon the problem that develops when the number of turbines in use rises.  The use of more turbines, at that limit produces, no more usable energy.  The investigators suggested that half of the turbines should be located in the sea, and that the other half should be located in identified high wind land areas across the globe. This looks like a promising development.
