Question

Which of the following is not a form of oceanic energy?

• A. Energy from biomass
• B. Tidal energy
• C. Ocean thermal energy
• D. Solar energy

Answer 1

Answer: (A), (D)

The correct options are
A Energy from biomass
D Solar energy

There are different kind of energies produced from sea. They are:

• Tidal energy: Tidal energy is harnessed by constructing a dam across a narrow opening to the sea. A turbine fixed at the opening of the dam converts tidal energy to electricity.
• Wave energy: electric power generated from waves
• Ocean current energy: ocean surface is comparable to wind which rotates the turbine to generate electricity.
• Ocean thermal energy: the warm surface-water is used to boil a volatile liquid like ammonia. The vapours of the liquid are then used to run the turbine of generator.

But energy from biomass, solar energy are not produced from seas. Hence they are not forms of oceanic energy.

Answer: option A and D.
