Interest in electricity from wind energy has been growing internationally. Large “wind farms” have sprung up around the world, each consisting of scores of turbines standing several hundred feet high with blades at least 100 ft across. Wind energy is relatively inexpensive and clean, without the air pollution and greenhouse gases that are byproducts of coalburning power plants or the worry about where to dispose of nuclear wastes. This makes the production of electricity from wind attractive.
