Question

What are the limitations of:
a) Solar energy?
b) Wind energy?

Answer 1

a) Limitations of Solar Energy:

1. Can be harnessed only in those places which get plenty of sunlight.
2. Cannot be harnessed beyond certain latitudes.
3. Cannot be harnessed during the night.
4. Current technologies are very costly.

b) Limitations of wind energy:

1. The wind has limited speed which lessened the resultant kinetic energy of the wind energy.
2. The speed of the wind is not constant. So the inconsistency in speed is not suitable for getting stable energy. It can not be controlled.
3. Production of wind energy is a long-term process i.e. it requires a long time to get a significant amount of energy.
4. To produce wind energy, we require a large area to make wind farms. Consuming a large place affects the surroundings.
5. It also increases the production cost.
6. If wind speed is low we can not get sufficient energy.
7. Wind energy depends on changes in season or weather. We can not always use wind energy.
