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.

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.
