It is not used on earth
That is called nuclear energy.
The energy used for sublimation and fusion is thermal energy. Sublimation requires the input of heat energy to convert a solid directly into a gas, while fusion involves the heat energy required to overcome the electrostatic repulsion between atomic nuclei to combine them into a new nucleus.
The nuclear fusion is not used now as a source of energy; probable possible in a far future.

Nuclear fusion releases huge amounts of energy. It occurs when the nuclei of elements are fused together at high temperatures and high pressure. Fusion energy is used to produce energy for some of the Earth's cities.
0% No country gets any of its energy from fusion as nobody has figured out how to build a controlled fusion reactor.
Nuclear fusion.
Nuclear fusion produces energy from the changes in the nuclear composition of the fuel, which is a mixture of deuterium and tritium. Essentially what happens is that some of the mass of the nuclei is destroyed and this releases energy
Fusion occurs when two atomic nuclei collide. The reaction that is produce by the collision can be used to provide energy. Fusion is the reaction that powers most active stars in the universe.
hydrogen fusion
Nuclear fusion produces nuclear energy
The Sun energy is from hydrogen fusion.
