Advantages of nuclear fusion process over nuclear fission to generate electricity are stated in the following points:
1. Unlike fission, during fusion tremendous amount of energy is liberated. Hence fusion of a very small mass generates large amount of energy.
2. Unlike fission the products of fusion reactions are not radio-active. Thus they are harmless and can be replaced easily.
3. Highly penetrating radiations are liberated during fission, which are highly hazardous.
