Fusion reactions release tremendous energy
The nuclear fusion is not used now as a source of energy; probable possible in a far future.

Nuclear fusion is the source of the sun's energy.

nuclear fusion
The sun's power source is nuclear fusion, where hydrogen atoms in the sun's core are fused together to create helium, releasing immense amounts of energy in the process. This energy sustains the sun's heat and light, making life possible on Earth.
The main source of energy of the sun is the fusion of hydrogen to helium.

It is hoped that building increased size and improved more efficient tokamaks will obtain fusion lasting for a longer time (so far less than 1 second has been achieved). The ITER apparatus is the next stage, but it will still only be an experiment with no way of harnessing the energy produced. That will be yet another stage, but I think there is little certainty yet that it will turn out to be successful, and it will certainly take many years of work before we can get energy from controlled fusion.
One significant difficulty in using fusion as an energy source is the challenge of containing and controlling the extremely high temperatures and pressures required for the fusion reaction to occur.
