Question

●Limitations of extracting energy from waves (or sea-water)...?​

Answer 1

$\huge\orange{\mathbb {\underline {Answer}}}$

Limitations of extracting energy from the wind:

A windmill requires wind of speed more than 15 km/h to generate electricity from wind energy also large numbers of windmills are required to get feasible output which covers a large area.

Limitations of extracting energy from waves:

Very strong ocean waves are required in order to extract energy from waves.

Limitations of extracting energy from tides:

Very high tides are required in order to extract energy from tides. Also, occurrence of tides depends on the relative positions of the Sun, moon, and the Earth.

Answer 2

Answer:

• Wave energy can only be used in areas where Waves are very strong.
• 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.
• 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.
