5) Discuss the significance of Ocean energy as a potential renewable energy in India. (250 words)
Why this question:
The Ministry of New and Renewable Energy has declared Ocean Energy as renewable energy. Thus, it is important from the point of view of GS paper III to examine the merits of ocean energy and its potential.
Key demand of the question:
The answer must write a short note on ocean energy as a potential renewable energy.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
Begin with brief introduction on ocean energy.
The question is straightforward and nothing much to deliberate. One must categorically discuss ocean energy as the renewable energy.
Discuss the significance of such an energy – vastness, ease of use etc. Oceans cover more than 70% of Earth’s surface, making them the world’s largest solar collectors.
The sun’s heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world.
Ocean energy is currently under-utilized and as on date, India does not have any installed ocean energy capacity. It is mostly exploited through a few technologies including wave, tidal, current energy and ocean thermal energy.
Conclude with way forward.
