The present invention provides methods and system for expanding a heated and pressurized stream comprising recycled CO2 across at least one turbine so as to generate power and output from the at least one turbine a turbine discharge stream comprising CO2; treating the turbine discharge stream comprising CO2 to form the recycled CO2; compressing the recycled CO2; and heating the compressed, recycled CO2 using at least two different sources of heat prior to passing the recycled CO2 into a combustor.
