In a method for generating energy in an energy generating installation ( 10 ) having a gas turbine ( 12 ), in a first step, an oxygen-containing gas is compressed in a compressor ( 13, 14 ) of the gas turbine ( 12 ), in a second step the compressed gas is supplied, with the addition of fuel, for combustion in a combustion chamber ( 15 ), in a third step the hot flue gas from the combustion chamber ( 15 ) is expanded in a turbine ( 16 ) of the gas turbine ( 12 ) so as to perform work, and, in a fourth step, a branched-off part stream of the expanded flue gas is recirculated into a part of the gas turbine ( 12 ) lying upstream of the combustion chamber ( 15 ) and is compressed. A reduction in the CO<SUB>2 </SUB>emission, along with minimal losses of efficiency, is achieved in that carbon dioxide (CO<SUB>2</SUB>) is separated from the circulating gas in a CO<SUB>2 </SUB>separator ( 19 ), and in that measures are taken to compensate for the efficiency losses in the gas turbine cyclic process which are associated with the CO<SUB>2 </SUB>separation.
