At the moment it's not because nobody has been able to get it to work for the sort of duration necessary for power production.
There are, however a couple of nice advantages over fusion:
- No radioactive waste products (the product is helium-4)
- No radioactive raw material (need heavy hydrogen)
- Theoretically large energy gain per reaction
On the down side it is technically very challenging, requiring extremely high pressure. Getting the inital reaction to start requires a lot of energy.
In principle fusion should be better for the environment because it does not produce the active fission products. The snag is that it has not been made to work yet, and won't be for many years to come, so as a practical way of producing electricity it does not come into play, and we have to say fission is better than a non-existent fusion
Nuclear fusion produce energy 400 times more than nuclear fission for the same mass.
The difference between Fusion and Fission is that Fission is easier to do and produces more energy than fusion reactions. However fission can be dangerous and is used in Nuclear reactors. Fusion however is safer and produces less energy but safely. It is quite difficult to cause a Fusion reaction however.
Nuclear energy as we use it now is from nuclear fission. Nuclear fusion is the joining up of nuclei rather than the splitting (fission), but it is not yet available on Earth.
It could be if it can be made to work! Two reasons: 1. Fusion does not produce the very active fission products that arise in nuclear fission 2. There are inexhaustible supplies of deuterium in the oceans.

it isn't
Energy from nuclear fusion is around 400 times more than that of nuclear fission for same mass.

Nuclear fission does not produce more energy than nuclear fusion. In nuclear fusion (6.4 MeV) per nucleon is given out which is much greater than the energy given out per nucleon (1 MeV) during a nuclear fission reaction.
Fusion produces no radioactive waste, and can yield a constant flow of energy instead of in nuclear fission where a nuclear power plant must be refueled and closed for 40-100 days out of the year.

Nuclear bombs use nuclear fission of some heavy element, usually uranium or plutonium. Thermonuclear bombs use the detonation of a fission bomb to ignite the fusion of hydrogen. Such weapons are more powerful than ordinary nuclear weapons because nuclear fusion releases more energy than nuclear fission, and because the process of fusion itself can be used to ignite more fission.

Lack (or reduced) fission products. Fission products emit most of the harmful radiation in fallout.
Fission is when two particles are split to make energy while fusion combines to particles. The result of fission is usually used up radioactive material while fusion results in helium. Fusion makes more energy than fission
