This energy store comprises a vessel in which drinking water and air are located under pressure. This vessel is located in an impounding reservoir or is installed underground. The pressure energy of the fluids is obtained by converting solar energy and wind energy. The stored energy offers a community an emergency supply of electric energy, and an emergency supply of air and water in the event of a disaster, particularly in the event of a nuclear explosion. By virtue of its simplicity, this structure offers a high degree of operational reliability.
