A method and device for non-emission electric energy production, consisting in: generating negative pressure or vacuum inside a pressure vessel in its upper part constituting a vacuum chamber in whose space a turbine rotor is situated; setting a height of a liquid or water column in the lower part of the pressure vessel constituting a liquid or water column below the turbine rotor, wherein the vacuum chamber is directly connected with the liquid or water chamber situated below the vacuum chamber, and a conventional interface between them is determined by the upper surface of the liquid or water column; closing a first closing means and supplying a liquid or water by a means for supplying a liquid or water to the vacuum chamber.
