Correct Answer: tidal

Solution : The correct answer is tidal.

Tidal energy is the energy which is generated by converting energy from tides into electricity using different methods. The power is generated by the turbines, which work when the rise and fall of the tides occur. It is a renewable form of energy. The Gulf of Khambhat, the Gulf of Kutch and the Sundarbans regions are the ideal conditions for utilising tidal energy.
