I WONDER - What Is Ocean Thermal Energy Conversion?

The video explains how the temperature difference between the ocean's warm surface water and cold deep water is used to boil a working fluid with a low boiling point. This process drives a turbine to generate electricity. Ocean Thermal Energy Conversion (OTEC) plants can be constructed onshore or offshore, offering significant power generation potential while being environmentally friendly.

What causes the temperature difference in the ocean that is crucial for OTEC?

• Tidal movements

• The sun heating the ocean's surface water

• Volcanic activity under the ocean

• Wind currents over the ocean

What is the role of the working fluid in the OTEC process?

• To clean the ocean water

• To boil and drive the turbine

• To store solar energy

• To cool down the turbine

Why is a low boiling point important for the working fluid in OTEC?

• It reduces the cost of the fluid

• It increases the fluid's density

• It makes the fluid more environmentally friendly

• It allows the fluid to evaporate at lower temperatures

Where can OTEC plants be constructed?

• Only onshore

• Only offshore

• Both onshore and offshore

• In desert areas

What is a significant advantage of OTEC plants?

• They are easy to build

• They require no maintenance

• They can be built anywhere

• They provide large amounts of power and are environmentally friendly
