Ocean Energy

The tidal waves and sea-waves are the main sources of ocean energy. India has a very long coastline, more than 6100 km, but the ocean energy production is limited. The suitable areas for the generation of tidal and sea-waves energy are:

(i) The Gulf of Khambat

(ii) The Gulf of Kachchh

(iii) The Estuary of Hugli

According to one estimate, the Indian coasts have the potential to generate over 40,000 MW of electricity. A plant has been established near Thiruvanantapuram (Vizhingam) which is generating about 150 MW of electricity through sea-waves.

The main problem in the exploitation of ocean energy is the high cost involved in the construction of civil works.
