UPSC CAPF – 2021
Solar energy, wind energy, and hydroelectric energy are all derived from natural processes that are continuously replenished (sunlight, wind currents, water cycles) and are thus considered renewable. Nuclear energy typically relies on the fission of heavy radioactive elements like uranium or plutonium, which are mined from the Earth and exist in finite quantities. While nuclear fuel sources are substantial, they are not naturally replenished at a rate comparable to their consumption, making nuclear energy generally classified as non-renewable, although it is a low-carbon energy source.
