Question

Which of the following sources of energy cannot be harnessed from the oceans

• A. Tidal energy
• B. Sea wave energy
• C. Ocean thermal energy
• D. Wind energy

Answer 1

The correct option is D

Wind energy

Explanation of the Correct Option-

1. Wind energy is the one that converts the wind (air) into electricity.
2. The wind turbines present to convert the kinetic energy of the wind into mechanical energy.

Explanation of the Incorrect Option-

Option (A)

Tidal energy is generated by the rise and fall of the oceanic tides.

Option (B)

1. The blowing of wind over the surface of the sea produces waves in the sea.

2. The kinetic energy which the waves possess is used to generate electricity.

Option (C)

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.

Thus, wind energy cannot be harnessed from the oceans.

Hence, option D is the correct answer.
