what is the cause of release of unusually large energies in nuclear fission reactions? How is the energy per fission calculated?

During the nuclear fission process a heavy nucleus splits to form particles. As we know that the subatomic particles are held together by strong nuclear forces and when the particle breaks it releases a tremendous amount of energy. The energy released during the fission reaction is calculated by using the famous relation:

E = mc2


Where:


E = Energy released


m = mass defect = Total Mass before the reaction – Total mass after the reaction


c = speed of light

A certain form of energy which is not sourced directly or indirectly from the sun and does not cause any pollution is very easily converted into electricity. This form of energy is however, not available everywhere. Moreover, it is technically very difficult and expensive to obtain it. Name the form of energy.
