Which one of the following is a non-renewable source of energy ?
A. Hydel Energy
B. Thermal Energy
C. Solar Energy
D. Wind Energy
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → B only
Thermal energy in this sense is the power generated by burning coal, lignite, oil or natural gas. These fossil fuels took millions of years to form and are exhausted once used, so thermal power is a non-renewable source.
Hydel, solar and wind energy all draw on flows that nature keeps replenishing — running water, sunlight and moving air — and are therefore renewable.
