Disadvantages of uranium:
1. Uranium is a possible polluting agent of the natural environment.
2. Uranium is a toxic and a radioactive chemical element.
3. Uranium release radium and radon.
4. Radioactive wastes are dangerous and need to be isolated.
Geothermal energy uses the heat of underground rocks to generate electricity. This is a renewable resource, because the rocks continue to be heated by uranium deposits in situ.
Nuclear energy, because uranium is a nuclear fuel for nuclear power reactors.
Uranium is nuclear fuel not renewable.The source of energy is the nuclear fission.
Nuclear energy via radiation.
Energy can not be created or destroyed. Therefore, to "generate energy" you need some other kind of energy - you convert one type of energy into another.
uranium, plutonium,etc etc
Electricity.
This is the energy of nuclear fission.The energy of fission is gigantic by comparison with the energy of fossil fuels.
Uranium don't emit directly heat; under nuclear fission the kinetic energy released and the energy of radiations is converted to heat and after to electricity.
This power is the nuclear energy from the nuclear fission.
Uranium is an element, not energy. It can be converted into energy by nuclear fission.
Nuclear energy is a type of energy that needs very little mass. Nuclear energy is used to generate electricity and heat.
