Wind Power Essay -- Exploratory Essays Research Papers

Wind PowerEnergy occupation causes more pollution than any other industry in the country. Currently, nearly all of the electric automobileity produced in the United States is generated by fossil fuel plants, nuclear plants, and hydroelectric plants. The build-up in the atmosphere of carbon dioxide and other nursery gases produced by the burning of fossil fuels now threatens far-reaching climate change. In addition to global warming, conventional methods of electricity generation release the gases responsible for acid rain, siemens dioxide and nitrogen oxide. In order 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 switching to renewable sources of pushing, such as wind power, are crucial steps to achieving this goal of sustainability. Wind power alone has the potential to go steady 20 percent or more of the worlds electricity needs within the next four to five years, (Johansson, 157). Wind power, however, is still a developing technology, and is consequently far from reaching its full potential. How Wind Machines WorkWind is the product of sunlight heating the surface of the Earth unevenly. Warmer atmospheric state rises and cooler air tumbles in to replace it, causing everything from gentle breezes to raging tornadoes. Whatever the amount of power in the wind, it can be harnessed by a car called a wind turbine. The most common type of wind turbine has a crosswise axis, with two or more aerodynamic blades mounted on the horizontal shaft, (AccessScience, Types of Wind Machines). As the wind passes over a turbines blade, pressure forms on the downwind side, thrusting it upward like a propeller. In these... ... states consumers the choice of who supplies their electric power and how that power is produced. With the implementation of at least some of these changes, wind power will eventually become a clean source of en ergy that all people can afford to rely on.
