Which of the following is not a renewable energy resource ?

  • A.Solar energy
  • B.Wind energy
  • C.Fossil fuel
  • D.Hydel power.

Answer: C

The resource that is not renewable is fossil fuel.

Coal, oil and natural gas formed from the remains of plants and animals over millions of years. Once burnt they cannot be replaced on any human time scale, so they are non-renewable, and burning them also releases carbon dioxide.

Solar energy, wind energy and hydel (hydroelectric) power come from sunlight, moving air and flowing water, which nature renews continuously, so all three are renewable.
