Question

An electrical-generation utility sometimes pumps
liquid water into an elevated reservoir during periods of
low electrical consumption. This water is used to generate electricity during periods when the demand for electricity
exceeds the utility’s ability to produce electricity. Discuss
this energy-storage scheme from a conversion efficiency
perspective as compared to storing a compressed phasechanging
substance.
