Whereas the nuclear fission, is exactly opposite of fusion reactions; in which one big atomic nucleus of an element splits into smaller parts usually creating many lighter nuclei.

So, it is clear from the above statements that nuclear fusion and fission reactions far more energy out less amount of matter. As it uses only the atomic nucleus of the elements to generate nuclear energy from it.
