Wind Power Essay -- Exploratory Essays Research Papers

vacate Power ability yieldion causes more pollution than any former(a) industry in the country. Currently, nearly all of the electricity produced in the joined States is generated by fossil fuel plants, nuclear plants, and hydroelectric plants. The build-up in the air travel of carbon dioxide and other greenhouse gases produced by the burning of fossil fuels forthwith threatens far-reaching climate change. In addition to global warming, conventional methods of electricity coevals release the gases responsible for acid rain, sulfur dioxide and nitrogen oxide. In secernate to prevent further degradation of our environment and successfully transition to a sustainable society, we must change our current patterns of production and consumption. Conservation and chemise to renewable sources of energy, such as wind power, are crucial stairs to achieving this goal of sustainability. Wind power alone has the potential to meet 20 percent or more of the worlds electricity needs within the attached four to five years, (Johansson, 157). Wind power, however, is still a developing technology, and is wherefore far from reaching its full potential. How Wind Machines WorkWind is the product of sunlight heating the surface of the Earth unevenly. Warmer air rises and tank air tumbles in to replace it, causing everything from gentle breezes to raging tornadoes. whatsoever the amount of power in the wind, it can be harnessed by a machine called a wind turbine. The most common emblem of wind turbine has a horizontal axis, with two or more slick blades mounted on the horizontal shaft, (AccessScience, Types of Wind Machines). As the wind passes oer a turbines blade, pressure forms on the downwind side, thrusting it upward resembling a propeller. In these... ... states consumers the choice of who supplies their electric power and how that power is produced. With the effectuation of at least some of these changes, wind power will ultimately become a clean source of energy that all peck can afford to rely on.
