Question

Ocean thermal energy is harnessed using the:

• A. energy stored by waves in the ocean
• B. temperature difference at different levels in the ocean
• C. pressure difference at different levels in the ocean
• D. tides arising out in the ocean

Answer 1

The correct option is B

temperature difference at different levels in the ocean

Ocean thermal energy uses the temperature difference between cooler deep and warmer surface water to run a heat engine and do useful work. This work is converted into electricity and stored for various uses.
