Question

What are the limitations of the energy that can be obtained from the oceans ?​

Answer 1

Answer:

The variable intensity of sea wavesHigh 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 formsLimits 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.
