Nuclear energy is renewable resources
Nuclear fission energy is not renewable fuel, its uranium reserves are limited, Pi
Non renewable, but the new energy, a huge amount, at least, people do not have to worry about
The fusion of deuterium or tritium, deuterium can be extracted from the ocean, almost inexhaustible. At present, humans have uncontrolled nuclear fusion can be achieved, but to energy can be effectively used by human beings, must be able to reasonably control the speed and scale of nuclear fusion, the scientists are trying to study how to control nuclear fusion.
