Why is electricity not stored for use during peak hours?
Electrical energy needs to be distributed as it is generated.
Storage of electricity is very expensive.
Storage of electricity would reduce its energy content.
We do not have the capacity to generate excess electricity for storage.
Electrical energy cannot be stored. Hence it needs to be used as it is generated.
(a) Explain how tidal energy can be used to generate electricity. (b) Why is tidal energy not likely to be a potential source of energy ?
