Question

Which of the following statements is NOT related to Ocean Energy?

A) Ocean Thermal Energy Conversion generates electricity due to the temperature difference between warm air above the sea surface and cold ocean water.

B) Tidal barrage systems are dam-like structures across ocean inlets.

C) Tidal stream systems use underwater turbines in moving tidal currents.

D) Wave energy systems convert the mechanical motion of ocean waves into electrical energy.

1. A. OTEC generates electricity due to the temperature difference between warm air above the sea surface and cold ocean water (Correct answer)
2. B. Tidal barrage systems are dam-like structures across ocean inlets that use tidal flow through turbines
3. C. Tidal stream systems use underwater turbines placed in moving tidal currents
4. D. Wave energy systems convert the mechanical motion of ocean waves into electrical energy

Correct Answer

Option A — OTEC generates electricity due to the temperature difference between warm air above the sea surface and cold ocean water

Detailed Solution & Explanation

The correct answer is OTEC generates electricity due to the temperature difference between warm air above the sea surface and cold ocean water.

Key Points

• OTEC uses the temperature difference between warm surface WATER and cold deep ocean water - not warm air.
• The statement incorrectly says warm air above the sea surface. Hence A is NOT correct.
