Abstract: The presented invention provides of hybrid thermodynamic cycle and a hybrid energy system as a method of reduction of fossil fuel consumption, maximum utilization of energy from renewable energy sources, increasing hybrid energy systems' efficiency and operating time, and transforming these systems from supplemental to primary energy producers. The hybrid thermodynamic cycle is a method of integration of incompatible types of energy, such as solar radiation, fossil fuel, kinetic energy of wind, of the ocean tide and wave, and of the river water. The integration process involves collection, conversion, operation, storage, and transmitting of incompatible energies using kinetic energy collectors, compressors, solar and air heat energy exchangers, air and thermal storages, piston and gas turbine heat engines, electrical generators, and air and electrical transmission lines. Surrounding air is used as an intermediate working substance in the hybrid thermodynamic cycle.
