C)  Uses water or steam heated by hot rocks near the surface. 
D)  Requires geysers and hot springs.

Question 10

Power generation using the Ocean Thermal Energy Conversion method

Accepted Answer

A)  Uses the temperature difference between shallow and deep ocean water to run turbines that generate electricity. 
B)  Uses the temperature difference between daytime and nighttime in tropical oceans to generate electricity.
