(a). Irrigation of terraced crop fields
(b). Lift irrigation of cereal crops
(c). Long duration energy storage
(d). Rainwater harvesting system
Explanation:
●
Pumped-storage hydropower is a
method of energy storage where water is pumped to a higher elevation reservoir
during periods of low electricity demand, and then released through turbines to
generate electricity during peak demand periods.
●
This process essentially stores
energy in the form of potential energy of water and then converts it back to
electrical energy when needed.
●
This makes it an ideal solution
for long duration energy storage.
