The seas are throbbing with energy. The ocean swells — the up-down movement of the water — is a source of energy, as are the tides, underwater currents and the crashing of the waves. All of this is steady, base-load energy, unlike other renewable energy sources that supply intermittently.
But mankind is yet to tap this energy source, save for sporadic efforts in the UK, Brazil and Denmark, among other countries. The problem is the cost , but that is not insurmountable. Technology and scale have always tamed costs, as was seen in the case of solar equipment and electric vehicles among several instances. Besides, until recently, there was no big need to go gunning for ocean energies. But the climate crisis has changed the dynamics.
Though precious little has been attempted in India to tap oceans for energy, a report by IIT-Madras and CRISIL estimates there is 40,000 MW waiting…
