Humans have harnessed wind power for thousands of years via sails and windmills. The first recorded windmills were used either as water pumps or to mill grain and were of vital importance in early attempt at mechanization of industry. Today large wind turbines are becoming popular the world over as a cheap sustainable energy source.
Modern wind turbines are colossal structure with blades often over one-hundred feet long and bases exceeding three hundred feet. At this extreme height, they are better able to catch the breezes that flow hundreds of feet over the ground. The friction caused by the wind power turning these great blades produces electricity which can then either be stored or used immediately. In the U.S.A. the use of these devices tripled between 2005 and 2008.
The popularity of this utilization of wind power is expected to increase as it is both so functional and surprisingly beautiful. One of the main criticisms of alternative energy is its unsightliness on the landscape. But most feel that these giant white towers add, rather than detract from the natural environment. And, home wind turbines are in high demand. In short, these turbines are here to stay.
