Imagine a life without lights, televisions, computers, trains, washing machine, refrigerators and microwaves. Imagine a planet so polluted that smog is in the air so bad that one cannot see very far, lakes and streams are poisoned, and land so badly scarred from people trying to find more energy sources. This may become reality in nearly future as a result of abuse of our energy resources. That reveals that energy is most important in our life, while a planet where we live is important too, a planet which effected by both generate the energy to meet our demands, and our use of energy.
As it can be seen that, there is relationship between generate electricity which is one type of our energy and pollution of environment.
In fact, environment crisis could solve by considering two important aspects, environment crisis occurred due to emissions of carbon dioxide, which caused by processes of generate electricity in order to meet the increase of demand for it. So the two important aspects are: to avoid abuse of energy consumption and to obtain environmentally friend electricity generation. This essay concentrates on the second aspect in order to offer some solutions of this problem.
There are two types of resources using to produce electricity, non-renewable energy resources and renewable energy resources. Non-renewable energy resources or known by fossil fuel such as wood, oil, gas and coal can be defined as solid, liquid or gaseous fuels formed in the ground after millions of years by chemical and physical changes in plants and animal residues under high temperature and pressure.
According to Franchi (2005:72) “renewable energy is energy obtained from sources at a rate that is less than or equal to the rate at which the source is replenished”, such as solar energy, nuclear power, wind power, bio fuel, geothermal, etc
Because of the increase of demand for electricity all over the world particularly in industrial revolution in developed countries, fossil fuels covered significant percentage of the demand for the electricity. Non-renewable energy resources need to change chemically the sources in order to obtain usable energy, for example by burn them. The obtaining of these resources, shipping them and converting them into usable energy cost high. Also burning them resulted in carbon dioxide CO2 and caused pollution to environment. In addition, non-renewable energy resources caused to reduce the forest, trees and green areas which consider the main source to feed the environment by Oxygen. (Harrison & Hester 2003)
Renewable energy resources which come in variety types have similarity in reducing of carbon footprint, and are much safer to the environment.
Nuclear Power is being promoted as the preeminent substitute for fossil fuel and considered as the future of energy needs. Nuclear is achieved by two processes, fission and fusion of nuclei of atoms. This process releases a huge amount of heat energy, which is then converted into...
