Question

Which form of the ocean energy can be harnessed

Answer 1

The form of ocean energy that can be harnessed is the mechanical energy from the tides and the thermal energy from the sun.

• Ocean thermal energy is harnessed by transforming the difference in temperature between the surface water and deeper water into usable energy.
• Difference in sea-levels at different times of day due to tides gives tidal energy. Tidal energy is harnessed by constructing a dam over a small opening into the sea, a generator installed at the dam's opening transforms tidal energy into electricity.
