Abstract
Ocean Thermal Energy Conversion (OTEC) is a clean marine renewable energy using temperature difference between the sea surface and the deep ocean to rotate a generator to produce electrical energy. As Indonesia is an equatorial country located at latitudes less than 20 degrees covered by 77 % ocean, thousand islands, strain and many difference of topography, OTEC is very compatible build in Indonesian. This paper discussed the potential areas of OTEC to be applied in Karangkelong Sulawesi Utara in Indonesia. The paper found that Karangkelong was high potential for application of OTEC. Electricity and fresh water produced by OEC are cheaper than current price market.
