Which of the following is a non-renewable source of energy?
Solar
Wind
Coal
Biomass
Coal
Coal is a non-renewable fossil fuel formed over millions of years from the remains of ancient vegetation subjected to intense heat and pressure. Because its rate of consumption by human activity far exceeds the geological time required for its formation, it is classified as a finite energy resource.
Coal is a non-renewable fossil fuel formed over millions of years from the remains of ancient vegetation subjected to intense heat and pressure. Because its rate of consumption by human activity far exceeds the geological time required for its formation, it is classified as a finite energy resource.
Under Article 48A of the Indian Constitution, the state is mandated to protect and improve the environment and safeguard the forests and wildlife of the country, which influences policies regarding the transition from coal to renewable energy.
Coal is the most abundant fossil fuel used for electricity generation in India.
The primary types of coal are Anthracite (highest carbon), Bituminous, Lignite, and Peat (lowest carbon).
Non-renewable sources are finite and cannot be replenished on a human timescale.
Coal-fired thermal power plants are the largest emitters of greenhouse gases in the power sector.
Solar, wind, and biomass are classified as renewable energy because they are naturally replenished on a short timescale.
Biomass is considered renewable because it is derived from organic matter that can be regrown, provided sustainable practices are followed.
Option A (Solar) is an inexhaustible energy source derived from the Sun's radiation.
Option B (Wind) energy is harnessed using turbines and is powered by atmospheric pressure differences.
C is correct тАФ Coal is a finite fossil fuel that cannot be naturally replenished once extracted and consumed.
When studying energy, also focus on the 'Paris Agreement' and India's 'Panchamrit' targets (Net Zero by 2070), which directly involve reducing coal reliance to mitigate climate change.
