Question

What are the limitations of the energy that can be obtained from the ocean 0?

Answer 1

Answer:

The limitations of the energy that can be obtained from the ocean are the following:

1) The movement of tides in the ocean is not constant, for this reason dams should be built to harness tidal energy. That's why dams are necessary.

2) The system is very costly and requires maintenance of the machine.

3) OTEC power plants have very low efficiency of utilizing ocean thermal energy.

__________________________

The different forms of energy that can be obtained from the ocean are tidal energy, wave energy and ocean thermal energy.

Following are the limitations of the energy obtained from ocean:

• The relative positioning of the earth, the sun and the moon as an impact on the tidal energy.

• For the conversion of tidal energy into electricity, high dams are required.

• To obtain electricity from wave energy, very strong waves are required.

• For trapping the ocean thermal energy, there should be a temperature difference of more than 20°C between hot surface water and the cold water at a depth.
