What are the limitations of the energy that can be obtained from the oceans?
The various forms of energy can be obtained from the ocean these are:
a. ocean thermal energy
b. wave energy and
c. tidal energy
Limitations of Tidal Energy:
i. Limited areas around the world which are suitable for building tidal dams.
ii. During high and low tides the rise and fall of sea-water is not enough to generate electricity on a large scale.
Limitations of Wave Energy:
In the world there are limits where the waves strike the shore lines with sufficient power that is sufficient to generate electric energy from the kinetic energy of the waves.
Limitations of Ocean Thermal Energy:
Ocean thermal plant involves high cost. To convert ocean thermal energy into electricity, a great variation in temperature difference of 20°C (or more) between the surface water of the ocean and deeper water is needed for operating OTEC power plants.
i. Limited areas around the world which are suitable for building tidal dams.
ii. During high and low tides the rise and fall of sea-water is not enough to generate electricity on a large scale.
