A system and method to efficiently store and convert erratic wind and solar electrical energy production to a source of reliable standard AC electrical power by means of an electric motor operatively engaged to power a pump. The pump in a sealed communication with a reservoir cavity evacuates air from the cavity to store the generated energy as potential energy in the form of a pressure differential with ambient atmosphere. Regulated air inflow into the evacuated cavity is employed to drive a generator or alternator to produce electric power which is synchronized with grid demand and communicated to the grid. |
