Ocean thermal energy is due to
(A) energy stored by waves in the ocean
(B) temperature difference at different levels in the ocean
(C) pressure difference at different levels in the ocean
(D) tides arising out in the ocean
Answer : (B)
Ocean thermal energy conversion is a process for producing energy by harnessing the temperature differences between ocean surface waters and deep ocean waters.
Temperature difference at different levels in the ocean is due to the availability of sunlight. As the sunlight is prevalent on the surface which increases the temperature of water but inner layers won’t get the same amount of heat which in turn creates a temperature difference.
Therefore option (B) is correct
