The combination of high year-round sea surface temperature, relatively short distance from the shore and excellent thermal profile of the oceans represent the ideal conditions for OTEC.
Clean and renewable energy - OTEC is a pollution-free renewable energy resource utilizing the natural temperature gradient that exists in the tropical and the subtropical ocean between the warm surface layer and the deep cold water.
Indeed, besides OTEC, there are other renewable energy resources but they are either limited in the amount of energy, very costly, or available only during sunny days. Moreover, they have no direct linkage with water and food production. OTEC is the best suitable renewable energy resource for sustainable development.
