We still have plenty of coal, though oil and natural gas are becoming less widely found and more expensive. We could go on using more and more coal for electricity, but it is not considered desirable because of the pollution it causes, which nuclear avoids
What it needs is energy. Nuclear energy is just one of many options to get energy.
Yes
Nuclear power plants are expensive to build and need highly trained engineers to operate. Fear of a nuclear accident and fear of nuclear waste mean many people don't want nuclear plants to be built near them.
One non-medical use of nuclear energy is power generation in nuclear power plants to produce electricity for homes and industries. Another example is the use of nuclear energy in research to study fundamental particles and phenomena in physics.
This seems very unlikely. Nuclear reactors need a lot of heavy shielding so are not suitable for transport purposes
Nuclear fusion produces nuclear energy
The energy released is nuclear energy.
Nuclear fission is a type of nuclear reaction that converts nuclear energy into thermal energy (heat), which can then be used to generate mechanical energy (such as electricity). So, fission nuclear energy originates as nuclear energy and can be converted into mechanical energy.
The energy stored in an atom's nucleus is nuclear energy. This energy is released through processes like nuclear fusion or fission, which involve manipulating the nucleus of an atom to release large amounts of energy.
Nuclear energy is already very usable - 104 reactors in the US alone.
