Question

The energy available due to the difference in the temperature of water at the surface of the ocean and deeper level is called

• A. Tidal energy
• B. Ocean thermal energy ($OTE$)
• C. Geothermal energy
• D. None of these

Answer 1

The correct option is B

Ocean thermal energy ($OTE$)

Explanation of the Correct Option:

1. Ocean Thermal Energy ($OTE$) is a type of energy that is caused by the temperature difference between the surface ocean water and the deep oceanic waters.
2. This principle is used in the generation of electricity by ocean thermal energy conversion plants.
3. A temperature difference of $20°$Celsius is required for its work.

Explanation of the Incorrect Option:

Option (A)

1. Tidal energy is generated by the rise and fall of the tides.
2. The gravitational interaction between the earth, the sun, and the moon causes these tides.

Option (C)

Geothermal energy is the heat that is produced by the hot rocks present deep inside the earth.

Thus, the energy available due to the difference in the temperature of water at the surface of the ocean and deeper level is called Ocean thermal energy ($OTE$).

Hence, option B is the correct answer.
