Question

What is known as Ocean thermal energy?

• A. The Sun's heat warms the surface water a lot more than the deep ocean water which creates ocean's naturally available temperature gradient.
• B. The Moon's heat warms the surface water a lot more than the deep ocean water which creates ocean's naturally available temperature gradient.
• C. The Solar cell's heat warms the surface water a lot more than the deep ocean water which creates ocean's naturally available temperature gradient.
• D. None

Answer 1

Answer: (A)

The Sun's heat warms the surface water a lot more than the deep ocean water which creates ocean's naturally available temperature gradient.

Ocean thermal energy conversion (OTEC) is a process or technology for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and deep ocean waters.

Energy from the sun heats the surface water of the ocean. In tropical regions, surface water can be much warmer than deep water. This temperature difference can be used to produce electricity from ocean water.
