Since the first energy crisis in the s, discussions have continued involving the rising dependencies on oil within countries around the world. As a result, research has since ensued concerning alternative energy sources and their utilization. Alternative or renewable energy sources, such as wind, wave, wind power essay, and solar are a result of nature, and thus do not contaminate or pollute the environment. Unlike renewable resources, fossil fuels produce carbon dioxide: a harmful element that is detrimental to the environment. Wind energy is perhaps one of the more studied options in regards to renewable energy resources, and presents a clean and environmentally friendly source that does not pollute the atmosphere with harmful by-products.
Despite all of the technological advances through history, wind remains to be beyond control. The earliest wind machines come from the ancient Persian windmills, dating to around B, wind power essay. C, which were constructed in order to grind grain. Later, windmills were brought to the Western hemisphere in the s A, wind power essay. By the thirteenth century, windmills were regularly used throughout the larger part of Europe Richards, The uneven heating of the earth from the sun generates wind. The atmosphere, which envelops the earth, obtains solar heat close to the equator, which maintains a consistently hot temperature throughout each year.
As the air moves around the earth, it averages the temperature extremes, thus producing surface wind, which can then be harnessed for the generation of power Richards, Need A Unique Essay on "Wind Energy Essay"? As a clean and environmentally safe source, wind energy does not produce detrimental gases that harm the atmosphere. The technology of wind energy is relatively simple and straightforward. The basic elements of a wind turbine are comprised of typically 3 wind power essay, a gearbox, and a generator.
Then, the gearbox transforms the low speed shaft of the rotor to a high-speed. Consequently, mechanical energy is transformed into electrical energy Richards, In spite of the fact that offshore wind turbines may present more of an expense in regards to installing and maintaining when wind power essay to onshore wind turbines, wind power essay, offshore wind turbines have many advantages. With wind turbines being located closer to the sea, this translates to a higher production of energy. However, wind farms that are located further inland and offshore do not present any visual impact. In addition, wind turbines produce quite a bit of noise, so locating them in more rural areas is another added benefit. Wind energy presents several environmental wind power essay. As a means of renewable, clean, and also sustainable electricity generation, wind energy is certainly one of the most economically friendly and effective renewable energy alternatives.
Although wind energy presents a host of advantages in regards to its energy and environmental friendliness, there are several challenges, as well. One of the primary challenges is the fact that wind power essay does not have the same strength at all times of the year. In addition, wind is unpredictable, meaning that in certain places of the world where wind is not always reliable, there should be a back-up source on days where the wind is less strong. For example, in Denmark, wind power essay, hydroelectric power is coupled with wind power in order to ensure electricity is provided at all times reliably Richards, wind power essay, Wind energy also produces an environmental disadvantage.
However, the number of fatalities for birds wind power essay relatively small when compared to fatalities related to building collisions, along with voltage wind power essay power lines. Offshore wind energy can also be detrimental as it changes the sea depth, and may also impact the coastal and landscape safety Richards, Lastly, wind energy presents an expensive challenge, as the repairs for offshore wind farms are more extensive when compared to onshore wind farms. Offshore wind farms require crane vessels, in addition to reliably good weather, in order to reach the turbines. Wind turbines require long repair periods, wind power essay, and thus offshore wind farms result in lower production of electricity.
However, it is undeniable that wind energy presents a viable and overall environmentally friendly option, especially in comparison to fossil fuels: the predominant source for energy used today. In summary, wind energy presents a number of advantages environmentally, economically, and for the overall climate of the Earth. However, there are several challenges associated with wind energy, such as its expensive and lengthy repairs, its threat to bird mortality, and the fact that wind is not always consistent, and therefore not always reliable. In spite of these challenges, wind energy still boasts a host of benefits to the climate, and thus is a viable option for generating energy as a renewable resource.
