Choose the false statement from the following statements on 'Energy Resources'.

  • A.Biogas causes greenhouse effect.
  • B.Solar energy is renewable energy.
  • C.Tidal energy is exhaustible.
  • D.Wind energy is non-polluting.

Answer: C

The false statement is Tidal energy is exhaustible.

Tidal energy comes from the rise and fall of the tides, which are caused by the gravitational pull of the moon and the sun. The tides continue indefinitely, so tidal energy is a renewable, inexhaustible resource.

The other statements can be accepted. Solar energy is renewable, and wind energy produces no pollution while generating power. Biogas is mostly methane, itself a greenhouse gas, and burning it releases carbon dioxide, so it does contribute to the greenhouse effect even though it is a cleaner fuel than wood or dung cakes.
