Question

Ocean thermal energy is 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

Answer: (B)

Ocean thermal energy is produced as a result of the temperature difference between the ocean's surface and deeper layers of water. The sun's heat energy, which causes the difference in temperature, is where the ocean thermal energy is obtained indirectly.

What is Ocean Thermal Energy?

• A technique for producing electricity uses ocean thermal energy. Ocean Thermal Energy, also known as Ocean Thermal Energy Conversion (OTEC), is the utilisation of the temperature differential between the cold and shallow sea to power a heat engine and provide meaningful work.
• Because sunlight's heat cannot get very far into the ocean, the deeper regions are colder.
• Here, the temperature difference affects how well the system works.
• The efficiency increases as the temperature difference increases.
• The tropics have the largest (20–25°C) temperature differences between the deep and shallow oceanic regions.
• Tropical regions get a lot of sunshine, which heats the ocean's surface and widens the temperature gradient.

Final Answer

Ocean thermal energy is due to temperature differences at different levels in the ocean.
