Out of the following which one is not a unconventional source of energy?
Tidal power
Geothermal energy
Nuclear energy
Wind power
Nuclear energy
Nuclear energy is classified as a conventional source of energy because it has been used for industrial-scale power generation for decades, similar to coal, oil, and gas. Unconventional sources (also known as renewable or non-conventional) are those that are still in developmental phases or have only recently been harnessed at scale, such as tidal, wind, and geothermal energy.

E=╬Фmc2 тАФ Einstein's mass-energy equivalence describing the energy released during nuclear fission
Q=mc╬ФT тАФ Heat energy transfer principle applied in steam generation
Nuclear power plants utilize controlled fission reactions. A heavy nucleus like 235U is bombarded by a neutron, causing it to split into lighter nuclei, releasing immense heat energy and additional neutrons. This heat is used to produce steam, which drives a turbine connected to an electrical generator.
Conventional sources are characterized by established infrastructure and widespread usage.
Nuclear energy is distinct from renewable sources; it is a non-renewable but low-carbon conventional energy source.
The International Energy Agency classifies nuclear power as a mature commercial technology.
High energy density compared to fossil fuels.
Provides stable base-load power unlike intermittent renewables.
Generates radioactive waste requiring long-term storage.
Risk of nuclear accidents and high initial capital costs.
Base-load grid electricity supply.
Nuclear-powered marine propulsion (submarines/icebreakers).
Nuclear energy is often grouped with 'Commercial' energy sources in economic textbooks.
Tidal, Geothermal, and Wind are collectively termed 'Non-conventional' because their commercial adoption started significantly later and they rely on natural phenomena that are not depletion-based.
C is correct тАФ Nuclear energy is considered a conventional source of energy due to its well-established, long-standing industrial use.
In competitive exams, always differentiate between 'Non-conventional' (Renewable/Recent) and 'Conventional' (Non-renewable/Established) based on the historical deployment of the technology.
