Question

Comment upon nuclear and oceanic energy.

Hint:

Nuclear energy offers high output with low greenhouse emissions but involves risk. Oceanic energy is renewable and abundant but needs more research and infrastructure to be widely used.

Answer 1

Nuclear Energy:
Nuclear energy is the energy released during nuclear reactions such as fission (splitting of heavy nuclei like uranium) or fusion (combining of light nuclei like hydrogen). In nuclear power plants, fission is used to produce heat, which generates electricity. It is a powerful, efficient, and clean source of energy, but it also poses risks of radiation, waste disposal, and accidents (e.g., Chernobyl, Fukushima).
Oceanic Energy:
Oceanic energy refers to energy derived from the sea, which includes:


Tidal energy – Generated by the rise and fall of ocean tides.

Wave energy – Generated from surface waves of the sea.

Ocean thermal energy – Generated from the temperature difference between surface water and deeper water.
Oceanic energy is renewable and eco-friendly but still underdeveloped due to high costs and technological limitations.
