IntroductionNuclear energy is a method of generating electricity that uses the heat released by the combination of uranium-235 and neutrons. Atomic energy was first used in 1951, which is within the last 100 years, but currently it is one of the main ways to produce electricity. This article will look at the success of atomic energy, in order to find out the reasons why nuclear energy has become a game changer that has created a great influence on our world.Game ChangerNuclear energy has given countries a new way to generate electricity efficiently, which has changed the trend of electricity generation in the world. Before the invention of atomic energy, fossil energy was probably the only source of electricity. After the discovery of nuclear energy, countries started investing in nuclear energy instead of the old one. According to “Nuclear Power Worldwide: Status and Outlook” (2007), nuclear energy provided 15% of the world's electricity in 2006. In 2008, the percentage even increased to 17%, as cited by Graham (2008). One possible reason is that atomic energy is more efficient than fossil fuels. Shah (2011) revealed that nuclear power plants in the United States can convert 87% of all heat generated into electricity, while coal plants and oil plants can only average 85%. Hence, the high generation efficiency of nuclear power plants has changed the trend of the world regarding the source of electricity. Lasting impact Nuclear reactors generate electricity at a lower cost, enticing countries to start using atomic energy. According to McDonald (2008), there are currently 30 countries that use nuclear energy as a source of electricity, some of them such as France and Belgium even use atomic energy as the main way to produce electricity.
