WIND

Wind Power is one of the fastest growing types of renewable energy sources. Wind power is also caused by the sun. The heat of the sun causes air to rise at a rate higher than it normally would, and air molecules rushing to fill the "gap" between hot and cold air cause wind. That wind is then used in turbines, large two or three bladed windmills that are moved by wind, which in turn power a generator that can generate electricity for a variety of uses, from home uses to powering large factories or an electrical panel. Like solar power, wind power provides only a small amount of the nation's electricity, but growing awareness of  alternative energy and the expansion of wind turbines, more and more electricity will be provided through wind power.
