The problem is that, although there are a range of different techniques for fusion, most of them produce less energy than is required to sustain the reaction. The most promising systems are "hot" reactors. The reaction takes place under conditions of very high temperature and pressure and it is difficult to safely contain such reactions. There are plans to build a prototype reactor that will produce a net energy output for "many minutes" but, alas, we are several years (possibly many years) from commercial fusion power stations.
Sun energy is produced by the fusion of two hydrogen atoms under immense pressure and heat in the core of the sun. The chemical energy (energy stored in the bonds of atoms) is released during this fusion.
A nuclear reaction - either fusion or fission - is required to turn matter into energy.

nuclear fusion
The latent heat of evaporation
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.
The expectation is that fusion reactors will provide large amounts of energy, and that they will be relatively environmentally-friendly.
hydrogen fusion
Nuclear fusion produces nuclear energy
The Sun energy is from hydrogen fusion.
The Sun energy is from hydrogen fusion.
Yes. Fusion energy would generate helium, a useful gas which is relatively inert and can easily escape. It would not liberate carbon dioxide into our atmosphere, which results in global warming. Fusion energy would be very clean and non polluting, and we have sufficient fuel (deuterium) to run fusion reactors for many thousands of years.
Fusion Energy Foundation was created in 1974.
Fusion Energy Foundation ended in 1986.
Because it is a fission process, not fusion
Nuclear fusion, like any process of producing power, uses fuel in doing so. In the stars, where fusion is the source of their energy, hydrogen is being used in fusion, producing helium plus energy. In any star the supply of hydrogen will eventually run out and the star will die, but its lifetime will be immensely long, many billions of years. On earth, if fusion can be made to work, it will use isotopes of hydrogen which are abundant, so as a source of energy it would last for many thousands of years.
