Nuclear Energy And The Environment Essays (1000 words) -
  Nuclear Energy And The Environment    Nuclear Energy and the Environment  In our society, nuclear energy has become one of the most criticized forms  of energy by the environmentalists. Thus, a look at nuclear energy and the  environment and its impact on economic growth.  Lewis Munford, an analyst, once wrote, Too much energy is as fatal as too  little, hence the regulation of energy input and output not its unlimited  expansion, is in fact one of the main laws of life. This is true when dealing  with nuclear power. Because our societies structure and processes both depend  upon energy, man is searching for the most efficient and cheapest form of energy  that can be used on a long term basis. And because we equate power with growth,  the more energy that a country uses, - the greater their expected economic  growth. The problem is that energy is considered to have two facets or parts:  it is a major source of man-made repercussions as well as being the basis of  life support systems. Therefore, we are between two sections in which one is the  section of resource availability and waste, and the other the continuity of  life support systems pertinent to survival.  Thus, the environmentalists believe that nuclear energy should not be used  for various reasons. First of all, the waste product, i.e. plutonium, is  extremely radioactive, which may cause the people who are working or living in  or around the area of storage or use, to acquire leukemia and other cancers.  They also show how billions of dollars are spent yearly on safety devices for a  single reactor, and this still doesn't ensure the impossibility of a melt  down. Two examples were then given of Chernobyl and Three Mile Island, in 1979,  when thousands of people were killed and incapacitated. Finally, the  environmentalists claim that if society wastes less energy, and develops the  means to use the energy more efficiency, then there would be a definite decrease  in the requirement for more energy producing plants.  On the other hand, some business men and economists say that the present  conditions should be kept intact, as the other forms of energy, e.g. oil,  natural gas and coal, are only temporary, in dealing with surplus, and give off  more pollution with less economic growth. Concurrently, countries wanted a more  reliable, smokeless form of energy not controlled by OPEC, and very little  uranium was required to produce such a high amount of resultant energy. Lastly,  they said that renewable energy is (a) unreliable in that the wind, for example,  could not be depended upon to blow, nor the sun to shine, and (b) were  intermittent in that a 1,000 mega-watt solar farm may occupy about 5,000 acres  of land, compared with less than 150 acres of land for a similar capacity  nuclear power generation station.  Because the energy technology that society employs directly influences the  quantity and quality of life, the energy option that is chosen should have the  greatest cost- benefit effectiveness as well as maximizing flexibility and  purchases. However, those who believe in continuous energy consumption growth,  seem to forget that there is only a limited supply of energy in every energy  system, and to overdo any resource may provide for an unacceptable impact upon  global and regional ecology.  Thus, if the business world pushes the environment as far as it can go,  Ceribus Paribus, please refer to figure 1. Thus, to use petroleum as a  substitute for uranium, which is needed to power the nuclear system, would not  be economically or environmentally sensible. I say this because, first of all,  there is a major supply of uranium considering it was one of the last energy  sources to be found as well as only a small amount of it is required to produce  a lot of energy. Secondly, petroleum gives off carbon monoxide which is one of  the reasons for ozone depletion; whereas, the uranium does not give off  pollution except that it produces plutonium which needs to be buried for more  than fifty years to get rid of its radiation. Finally, because so much of the  petroleum will be required to power the vast area that nuclear energy can cover,  the cost to us as the consumer would be massive! This would mean slower  economic growth and/or expansion, especially when compared to nuclear energy.  Therefore: Ceribus Paribus - (a) if the cost decreases, the demand increases,  and - (b) if the cost increases, the demand decreases. Please refer to figures  #2 and #3 respectively.  Nuclear plants are now replacing coal burning plants. It will cost
