Question

What are the limitations of extracting energy from
A. Wind
B. Waves
C. Tide

Answer 1

Hint: Renewable energy is generated from renewable sources like sunlight, wind and tides and so on. These energies are sustainable and eco-friendly, causing less harm to the environment. The major drawbacks include the cost of setting up the plant.

Complete step-by-step answer:
The limitations of wind energy are:

1. High speed winds are needed for generation of energy which may not be available in many places.
2. The investment costs to set up a wind farm is very high, due to expensive modern technology.
3. Large area is needed to set up the wind farms.

The limitations of wave energy are:

1. Wave farms can be setup only in the regions where the waves are strong
2. Since the strength of waves is unpredictable, the energy produced by this is also unpredictable.
3. The setup is costly as the plants need constant maintenance.

The limitation of tides are:

1. The availability of dams to construct tides is limited.
2. The tides are not enough to generate electricity on a scalable level.
3. The costs and risks of maintenance dams are high. Needs to be monitored regularly, especially during monsoons.

Additional Information:
These energy has reduced the $CO_{2}$ emissions which causes depletion of ozone layer.The most popular renewable energy sources currently are:

(a)Solar energy
(b)Wind energy
(c)Hydro energy
(d)Tidal energy
(e)Geothermal energy
(f)Biomass energy

Note: All the given options are renewable resources, which are eco-friendly in nature. The main drawback of these forms of energy is the high cost of initial set-up and maintenance. Also these resources need large areas for the construction of the plants.
