The work is devoted working out of scientific bases, creation of methods of the analysis of efficiency cogeneration schemes and installations on the basis of piston thermal engines. In work the basic advantages of application decentralised cogeneration sources of power supply and their lacks are stated. On the basis of power, ecological and technological indicators of efficiency the comparative analysis has been made and schemes and the equipment in a range of elec-tric and-or thermal capacity to 20 MW are offered. There is offered thermophysics model that describes thermo- and hydrodynamics processes in an underground permeable to water collector at festering in its cold heat carrier and numeral decision method of model equalizations by the applied CFD package. There are executed numerical calculations and conducted analysis of parameters change of filtration stream, cooling permeable collector kinetics and surrounding mountain range, distributing dynamics of pumping cold heat carrier in a collector on the example of the real operating geothermal circulation system. There is conducted analysis of experimental block of the geothermal setting exploitation with the separate receipt of thermal and electric energy on the basis of gas saturated geothermal ectoplasm the use. There are shown considerable backlogs of its economic and power efficiency increase. The possibility of using landfill biogas for production of electricity and heat, and an overview of biogas technology collection with solid waste landfills. Presented environmental and economic indicator in technology production and use of biogas landfill solid household of local waste. An overview of technologies collect biogas from MSW.The proposed environmental performance settings extraction and use of biogas landfill. An economic performance technology of generating and using biogas landfill. Consider using biogas obtained in the process of anaerobic fermentation of organic substances such as agricultural drifts away virgins to produce electricity and heat. The results of energy and economic efficiency of the implementation of station energy conservation on biogas. Consider the circuit decision on biogas energy plant. Installed biogas energy potential. An assessment of economic feasibility of cogeneration plant for biogas energy. Considered the motivation and need to build biogas plants. Indicate that barriers to the creation of biogas cogeneration plants in Ukraine.
