Ocean Thermal Energy Conversion (OTEC) is a sustainable ocean energy conversion system with the potential to tap extraordinarily large amounts of energy from the oceans. Every day, more than 3 GWh of energy is absorbed by each square kilometer of equatorial ocean water. OTEC plants operating in this region of the open ocean could produce sufficient energy to create enough anhydrous ammonia to fuel all the automobiles in the world. We have the capability to replace the Middle East as the source of the worlds transportation fuel while at the same time eliminating the billions of tonnes of carbon dioxide emissions from transportation that are exhausted into the atmosphere each year.
