What are the types of energy that can be harnessed from the oceans? What are the limitations of the energy (5) that can be obtained from the oceans?
Answers
Answer:
• The ocean can produce two types of energy: thermal energy from the sun's heat, and mechanical energy from the tides and waves.
•Limitations of harnessing Energy from Ocean are given below:
The variable intensity of sea waves
High tidal power plant construction costs. This is because they need to be incredibly sturdy to withstand the force of the sea. High dams are required to be built to convert tidal energy into electricity.
Negative influence on marine life forms
Limits arising from the location due to limited availability of sites with sufficiently high tidal ranges or flow velocities. Very strong waves are required to obtain electricity from wave energy.
Tidal energy depends on the relative positioning of the Earth, moon, and the Sun.
To harness ocean thermal energy efficiently, the difference in the temperature of surface water (hot) and the water at depth (cold) must be 20ºC or more.
