The Ocean is the largest collector of the solar radiation, some have speculated that it, accumulates around 250 billion barrels of oil equivalent. The means of harnessing this amount of solar energy absorbed into the ocean and converting it to electricity is called Ocean Thermal Energy conversion (OTEC).
Exergy analysis is on the second law of thermodynamics. It stipulates that all macroscopic processes are irreversible. Every exergy loss causes a decrease in the useful effect of a given process or increased consumption of the means that drive it. The exergy analysis pinpoints places where exergy destruction takes place. Such an analysis is therefore critical to not only the improvement of thermochemical or electrical processes but also energy processes which occur in the human body and the in the environment.
