Nuclear energy, as we all know, is the energy that is induced from the nuclear source. Many kinds of nuclear reactions are nuclear fission, nuclear fusion, and a lot more. The current energy sources that we use are either polluting the environment or causing a threat to humanity. When joined these two together, doesn’t a beautiful question strike out mind – Can nuclear energy be the replacement source. “Why not?” will be my answer to this. And the reasons for my answer are very simple which all of us would definitely have thought at some point of time.
