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

Wind - A Renewable Energy witness Wind is c totallyed a renewable energy source because wind leave alone continually be produced as long as the sun shines on the creation. The suns contribution to wind energy deals with converting air into commove or cool wind. Wind is produced by the irregular heating of the earths surface by the sun. On land, the fiery air 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 apply more often in the United States for its safer standards regarding the environment and finance. To fix this wind, turbines ar used to convert the renewable resource into electricity. The energy in motion or kinetic energy is then mechanically processed. Windmills ar 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 batteries for t ractors on farms, etc. Most of todays windmills extract about 30 % of the winds energy (www.earthsci.org). Windmills are just as efficient as coal the difference betwixt them is that air is less polluting than coal. Unfortunately there is no such occasion as a 100 percent efficient power source. For a completely 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 order to convert electricity, windmills depend ...
