A system for generating energy is disclosed. The system (100) combines an organic rankine cycle and a vapor compression cycle to generate energy. A turbine (114) expands high pressure primary refrigerant vapors to generate energy. The low pressure primary refrigerant vapors obtained in the turbine (114) are used to evaporate a secondary refrigerant in an evaporator (102). The system (100) eliminates water-related problems such as water-freezing, formation of water vapor plumes and water pollution issues, associated with conventional organic rankine cycles.
