Question

Ocean thermal energy is generated due to ___.

• 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 is generated due to temperature difference at different levels in the ocean. The warm water from the surface and the cold water from the depth of the ocean are collected separately. The warm water is used to convert a low boiling liquid into steam, which is then used to rotate the axle of a generator producing electricity.The cold water is further used to cool the steam and condense it back to water.
