Nuclear fusion should be the future of any sane government energy policy. It is the most energy dense method of power generation that we are aware of. It's clean, and it doesn't emit any of those harmful, poisonous, carbon dioxide fumes we hear about from time to time.
Whereas nuclear fission - the type of nuclear power generation in use today - occurs when energy is released as the result of splitting an atom apart, fusion occurs when atomic nucleii fuse together to form a heavier nucleus. This is the process going on inside the Sun.
