Answer 1

The correct answer is Nuclear Energy.

Key Points

Nuclear energy is derived from reactions involving the nucleus of an atom, typically through nuclear fission or fusion.
The process of nuclear fission involves splitting heavy atomic nuclei (e.g., uranium-235 or plutonium-239) to release a large amount of energy.
In nuclear reactors, the energy released during fission is used to generate heat, which is then converted into electricity.
Nuclear power is considered a clean energy source as it does not produce greenhouse gases during electricity generation.
Globally, nuclear energy contributes to approximately 10% of electricity production, as reported by the International Atomic Energy Agency (IAEA).

Additional Information

Radioactive Isotopes: These are unstable atoms that release radiation as they decay into more stable forms, a key component in nuclear reactions.
Nuclear Fusion: Unlike fission, fusion involves combining light nuclei (e.g., hydrogen isotopes) to form a heavier nucleus, releasing significant energy. This process powers the sun and stars.
Advantages of Nuclear Energy: High energy density, low greenhouse gas emissions, and long-term reliability make nuclear energy a sustainable alternative to fossil fuels.
Challenges of Nuclear Energy: Safe disposal of radioactive waste, high initial costs, and potential risks such as nuclear accidents (e.g., Chernobyl, Fukushima) remain significant concerns.
Common Uses: Apart from electricity generation, nuclear energy is used in medical applications (e.g., cancer treatment), space exploration (radioisotope thermoelectric generators), and industrial processes.
