Ocean thermal energy conversion (OTEC) is a method to produce electricity by using the temperature differences between warm ocean surface and cool deep ocean water to run a heat engine. If temperature difference is greater, then more energy will be produced. About 70% of the earth’s surface is covered by oceans, which are continuously heated by the sun. Extracting the solar energy stored in an ocean is carried ...
