A New Approach to Pumped Storage Hydropower

Pumped-storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized as open

Pumped-storage hydroelectricity

OverviewHistoryMethodsApplicationsUse casesCapacityEconomicsResearch

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. En

Is it possible to generate electricity using a water tower?

The quick and dirty answer to your question is yes. You could create electricity using the potential energy of the water stored in the water tower of height (h meters). HOWEVER, you would also have to consider the amount of energy that would be needed to pump the same volume of water to a height of h meters.
