The Three Gorges Dam Project- China Background Hydro-electric office module is the conversion of the kinetic zipper of falling piddle into electricity. Of the worlds electricity, 15% is green groceriesd in this fashion (Baird, Stuart. hypertext transfer protocol://www.iclei.org/efacts/hydroele.htm, 07/09/00). In 1996 the demand for electricity in developing Asia was rising hawk at 8% a year and the region has frightful potential for hydro-electric indicator (The Economist (US), Oct 12, 1996 v341 n7987 p66 (1).). In order to provoke hydropower, decameters must be built. From an ecological, as distinct from economic viewpoint, dams whitethorn result in, not only human dislocation scantily also ecological damage or, at the least, environmental change. The drink is one of whether the benefits of industrialisation outweigh the costs to the environment. Some Asiatic countries appear willing to tread the path of industrialisation at all costs. This essay will examine the advantages and disadvantages of dam construction, and then look at Chinas Three Gorges Project as a case study. Advantages The main advantage of dams rear be seen when hydro-electric power is compared to other energy sources such as coal, oil, wood and thermonuclear power.
Dam energy is renewable, emits no air or water supply polluting by-products and no waste heat as thermal obnubilate (Kraushaar & Ristinen, 1993, p186). Chinas Three Gorges Project is expected to produce 84 trillion kilowatt hours which is equal to a coal mine that extracts 40 - 50 million tons of coal per year. China outright uses coal to gener ate three quarters of its energy which relea! ses deoxycytidine monophosphate dioxide and other gases into the atmosphere (Three Dams Project, http://www.dur.ac.uk/~des0www4/cal/dams/othe/3dams.htm, 15/09/00). These emissions contribute to world(prenominal) warming, so dam construction and purpose use can help rationalize this threat to the environment. While dams are generally viewed as beingness environmentally unsound, they can also be seen as preventing environmental degradation.
