Wind - A Renewable Energy Source Essay example -- Alternative Energy R

undulate - A Renewable Energy Source Wind is called a renewable energy source because wind will continually be produced as long as the sunshine shines on the earth. The suns contribution to wind energy deals with converting pushover into love or cool wind. Wind is produced by the irregular heating of the earths surface by the sun. On land, the warm oxygenate spreads and goes up in the sky, in the water, heavier and cooler air moves in to take the warm airs place, thus providing local winds. This power source should be employ more often in the United States for its safer standards regarding the environment and finance. To capture this wind, turbines are employ to convert the renewable resource into electricity. The energy in gesticulate or kinetic energy is then mechanically processed. Windmills are used in the United States amongst other countries in the world. They are used to heat water, refrigerate produce, dry crops, irrigate crops, heat buildings, and charge ba tteries for tractors on farms, etcetera Most of to twenty-four hourss windmills extract about 30 % of the winds energy (www.earthsci.org). Windmills are fairish as efficient as coal the difference between them is that air is less polluting than coal. Unfortunately there is no such thing as a 100 percent efficient power source. For a solely efficient source of energy, the power plants have to run all day and all year without interruption (www.eia.doe.gov). To do the fact that in put to convert electricity, windmills depend ...
