Which of the following is a non-renewable resource?
Show answer & explanation
Correct answer: A
Explanation
Correct Answer
Coal
Explanation
Coal is a non-renewable resource because it takes millions of years to form from the remains of ancient plants buried deep under the Earth's crust, and it cannot be replenished at the rate it is consumed. Once exhausted, it cannot be replaced in a human lifespan. On the other hand, wind, tidal, and solar energy are renewable resources as they are constantly replenished by nature and are virtually inexhaustible.
Key Points
Non-renewable energy resources include fossil fuels such as coal, petroleum, and natural gas, as well as nuclear fuel like uranium.
These resources have a high carbon footprint, meaning their combustion releases large amounts of greenhouse gases like carbon dioxide (CO2), contributing heavily to global warming.
Unlike renewable alternatives, the extraction and utilization of non-renewable resources often cause significant environmental degradation, including air pollution and habitat destruction.
Additional Facts
Coal is primarily classified into four main types based on its carbon content and heating value: Anthracite (highest quality), Bituminous, Sub-bituminous, and Lignite (lowest quality).
India is one of the largest producers and consumers of coal in the world, relying heavily on it for electricity generation through thermal power plants.
International agreements like the Paris Agreement encourage nations to transition from non-renewable fossil fuels to clean, renewable energy sources to limit global temperature rise.
Important Questions
