Ocean Energy & Geothermal Energy topics include: Tidal power, tidal energy, wave energy, ocean thermal energy conversion, geothermal energy, hydrothermal systems and geothermal conversion problems.  Ocean thermal energy and geothermal energy are different types of energy.  Ocean thermal energy is the energy that comes from the temperature difference between the warm surface water and the cold deep water. Ocean thermal energy converter (OTEC) power plants use this temperature difference to produce electricity.  Geothermal energy is the energy that comes from the hot rock and water deep... Show more
