What are the disadvantages of the energy from the sea Class 10?

Disadvantages of using Wave Energy

• Wave energy can only be used in areas where Waves are very strong.
• Since the waves are erratic, the energy produced from wave energy is unpredictable. So, it is not a reliable source of energy.
• The initial set-up costs are high.
• It can harm the marine ecosystem.

What are the disadvantages of ocean currents?

Disadvantages – Sometimes there will not be a lot of waves (which means no energy), It could interfere with ocean ecosystems in the area of the currents, and the temperature is raised wherever ocean currents are happening (which could also ruin an ecosystem).

What are the disadvantages of ocean thermal energy?

Disadvantages of an OTEC system

• Capital investment is very high.
• Conversion efficiency is very low about 3-4% due to the small temperature difference between the surface water and deep water.
• The low efficiency of these plants coupled with high capital cost and maintenance cost makes them uneconomical for small plants.
