Question.
What are the limitations of energy that can be obtained from the oceans ?
What are the limitations of energy that can be obtained from the oceans ?
solution:
The energy obtained from the oceans is
(1) tidal energy, for which very few suitable sites are available for construction of dams and the generation is intermittent and not very large.
(2) sea-waves energy, where power output is variable and the currently available technologies are quite expensive.
(3) ocean thermal energy, where the conversion efficiency is quite low but a lot of capital investment is required.
