Nuclear Energy
Energy consumption has become a necessity and an important part of our daily life in the past 10 years. It seems that the world is looking for an energy source that is cleaner, cheaper and more efficient and since nuclear energy has emerged it has become the forerunner for alternative energy sources. ‘As of 2004, nuclear power provided 6.5% of the world's energy and 15.7% of the world's electricity, with the U.S., France, and Japan together accounting for 57% of nuclear generated electricity’ (‘Nuclear energy facts’ 2007). Nuclear energy can be a doubled edged sword as it can be used for peaceful uses or used to manufacture weapons of mass destruction which can put the world in danger. As more countries begin to

But after all the advantages of using nuclear energy outweigh its disadvantages as nuclear plants emit less than one-hundredth of carbon dioxide gas compared to coal or gas-fired energy plants so there is a very little effect on the environment. Humans living next to coal-fired power plants are exposed to higher radiation doses than those living near nuclear plants, where the former is harmful to human health and may be responsible for acid rain. On the other hand dependence on nuclear energy is now increasing in most countries as nuclear reactors use uranium as a fuel which is found everywhere on earth. It is inexpensive and easier to transport than other fuels which makes them less dependent on oil and foreign fuel from other countries.
No doubt that most people believe that the world is a better place than it was 20 to 30 years ago. But actually, the world is becoming a very dangerous place with number of countries owning nuclear weapons increasing. ‘In all, there are approximately 27,600 nuclear weapons in existence’ (‘Weapons around the world’ 2005). They are constructed using either highly enriched uranium or plutonium, which then relies on two basic ways to release energy from an atom which are nuclear fission and nuclear fusion. Nuclear weapons are then divided into two groups, fission bombs which break apart heavy atomic nuclei and fusion bombs which fuse light nuclei. With many recent…
