Atomic Bombs Nuclear Energy
244 wordsNuclear Energy should be produced because it is an alternative to fossil fuel. Nuclear energy helps to conserve our national resources that we use as fuel such as coil, oil, and natural gas. Another pro of nuclear energy is that radiation that is given off by nuclear energy is mostly thought of a very dangerous thing but it can be used in positive ways too. For example, if you break a bone a doctor can inject a radioactive phosphorous compound, which is a compound that concentrates on active gro...
