Renewable energy - Essay Example energy is energy generated from resources that are naturally refilled on a human timescale such as rain, geothermal heat, waves, sun, and wind (Harvey and Brown 41). The cost of generating hydropower is low making it the most preferable source of the world’s renewable energy. Further, hydroelectric plants are said to have long economic lives with some plants having the ability to be in service for over 50 years. The cost of operation is not high since plants are automated and have few people on site during normal operations. In addition, hydro energy is more flexible source of power or electricity because plants can be ramped or inclined up and down to adapt to transforming energy needs. Once a hydropower dam is constructed, the project generates no direct waste to the ecosystem and has low production of greenhouse gases than fossil fuels (Somma 46). It is vital to note that many nations recommend energy sources such as hydropower, wind and sun because they do not emit any harmful chemicals and gases such as carbon dioxide and it is not a major contributor to global warming via carbon dioxide. Energy source such as hydropower is a renewable source of energy or power because rivers and streams are naturally available. Further, hydropower is not expensive as compared to energy produced from nuclear energy or fossil fuels. The advantage of hydroelectric reservoirs is that they are able to tackle daily, seasonal, and peak loads. For instance, when the demand of electric falls, the reservoirs or dams store water while some installed electricity generators are used to store excess energy (Harvey and Brown 33). Biofuel production revolves around the fact that biofuel is a renewable source of energy. Biofuels have a source material and unlike oil, which often takes thousands of years for the fossil fuels to be produced, the biofuels are renewable because new crops can often be grown and the waste material collected for production of oil. Biofuel production has helped

Letter to an Editor of the Campus Newspaper - Essay Example It was not so much the revision of my own thoughts but revising my expression of them. Argumentative submissions and genre interpretation is always difficult because my writing is subjective. I can distinctly recall worrying about â€Å"coming across† the right way. I think that there is a line between conveying your message and censuring it for the eyes of others so I was always careful to not cross it. I find that in the argumentative process, I become easily lost which demonstrated my total lack of discipline. Thus my first decision was to make a concerted effort to not inject myself too much into my argument. I had a problem identifying my audience for the genre translation and as a result found myself consistently revising but to what end? Ultimately I would begin again and again because I kept identifying different targets and it took quite some time before I came to the realization that the interpretation could be generally applied. 2. Describe the rhetorical situation as you see it for both your argument paper and your genre translation. Be sure to discuss both audience and purpose for both documents. A rhetorical situation is far easier to convey when it is applied to an argument because the sense of urgency is raised by the issue being argued. The audience is hopefully automatically compelled by the tone and terms of the issues presented in the argument itself. Moreover, one tends to become personally involved in their arguments which also is revealed in their writing. An argument is an attempt to convince whereas genre translation is equally subjective, but without the force or conviction behind it. I find that the audience and purpose of genre translation is far harder to convey than that of the argument. Argument is an imperative whereas genre interpretation seems to be an attempt to bridge a gap without conviction. With genre interpretation it is difficult to contemplate whom it is that
