General Science question from Laboratory Attendant exam, 2026 by JKSSB
Which of the following statements is NOT related to Ocean Energy?
Last updated Jun 18, 2026
Correct Answer:
Option A —
Ocean Thermal Energy Conversion generates electricity due to the temperature difference between warm air above the sea surface and cold ocean water to drive a turbine.
Why is this statement incorrect?
Ocean Thermal Energy Conversion (OTEC) does not use the temperature difference between the air and the water. Instead, it works by exploiting the temperature difference between warm surface seawater and cold deep ocean water (typically from around 800–1,000 meters deep) to run a heat engine and generate electricity.
All the other options (B, C, and D) accurately describe genuine methods of capturing ocean energy (Tidal Barrages, Tidal Streams, and Wave Energy).
