Otto HahnNuclear energy is a non-renewable energy source that is generated by splitting atoms. It is used to generate electricity and is one of the most efficient sources of energy.Nuclear energy is the energy released during a nuclear reaction, either through nuclear fission or nuclear fusion. In nuclear fission, the nucleus of an atom is split into two smaller nuclei, releasing a significant amount of energy. Nuclear fusion, on the other hand, involves the combining of two atomic nuclei to form a heavier nucleus, also releasing a vast amount of energy. Nuclear energy is known for its immense power potential and its ability to generate electricity on a large scale.- Energy Output: High
- Fuel: Uranium, Plutonium
- Radioactive Waste: Produced
- Greenhouse Gas Emissions: Low
- Operational Cost: High Initial Cost, Low Fuel Cost
