Final answer:
Nuclear energy is a nonrenewable energy source produced through fission reactions in a nuclear power plant. It is not a fossil fuel but still has finite reserves as it relies on uranium as a fuel source.
Step-by-step explanation:
Nuclear energy is a type of nonrenewable energy that is produced in a nuclear power plant through the process of fission reactions in a radioactive fuel, usually uranium.
Unlike fossil fuels such as coal, petroleum, and natural gas, nuclear energy is not derived from the remains of ancient plants and animals. Instead, it harnesses the energy released from nuclear reactions in the nucleus of an atom.
Although nuclear energy is not classified as a fossil fuel, it is also considered non-renewable because its fuel source, uranium, is finite and will eventually run out. Furthermore, nuclear energy presents its own set of environmental challenges, such as the safe disposal of nuclear waste.
