The scientific novelty of the results presented in this article is to substantiate and expand the possibilities of using global and local geographic information systems (GIS) to assess the potential of renewable energy sources in Ukraine. GIS analysis focused on key resource parameters can help identify territories for development of renewable energy sources and assess of their possible technical potential, as well as the possibility of effective integration of technologies for the use of renewable energy sources in the energy sector of Ukraine. In this paper the possibilities for using geographic information systems to assess the potential of renewable energy sources in Ukraine are analyzed. The possibility of using the Global Atlas of the International Renewable Energy Agency (IRENA) to support planning of technologies for the use of energy from biomass is analyzed. The data can point to large-scale programs and applications in relation to key parameters (quality resources, transmission distance, population density, terrain and site protection), helping identify additional areas for development of renewable energy sources and give an approximate assessment of technical potential. It is determined that the software products of IRENA are able to support national and regional planning of renewable energy technologies, help establish the viability of future renewable energy facilities and help project developers identify and analyze promising facilities for the implementation of technologies using renewable energy. The application of geographic information systems of Ukrainian web resources (“UA MAP”) for assessing the potential of renewable energy sources and energy efficiency in Ukraine is been analyzed. The scientific novelty of the results lies in applying global and local GIS for comprehensive assessment of the potential and effectiveness of the use of regional non-traditional and renewable energy resources on the territory of Ukraine. This makes it possible to assess the possibilities of generating additional electric and thermal power for the needs of the regions of Ukraine using non-traditional and renewable energy sources. A comprehensive methodology for the use of GIS is proposed for assessing the potential of non-traditional and renewable energy sources at the regional level in Ukraine, taking into account energy, environmental and socio-economic factors affecting the placement of non-traditional and renewable energy facilities.

Accelerating the transition of the energy sector to ecologically clean energetics using renewable energy technologies will ensure the security of the energy sector of the European Union based on highly energy-efficient and cost-effective technologies for generating heat and electricity. The aim of the study is to assess the economic and ecological aspects of the implementation of renewable energy technologies in Ukraine based on the analysis of trends in the transformation of both the global and the European energy sector. The approach proposed in this article makes it possible to reasonably determine the prospects for the use of environmentally safe energy-saving technologies using renewable energy sources. The analysis of the economic and environmental aspects of energy production based on renewable energy technologies, the condition of development and directions of transformation of the European energy sector is illustrated on the basis of a comprehensive assessment of the efficiency of the use of energy-and resource-saving, environmentally safe and cost-effective innovative technologies of non-traditional and renewable energy sources. This is achieved through the use of a comprehensive generalized dimensionless criterion of energy-ecological-economic efficiency of innovative technologies with the aim of increasing the level of energy-economic efficiency and environmental safety of the energy sector. According to this approach, it is determined that the effective integration of a certain energy-and resource-saving, environmentally safe and economically efficient innovative technology using renewable sources in Ukraine is possible.

The study analyzes the indicators of the efficiency of cogeneration heat pump installation (CHPI) in the thermal scheme of heating boiler house. It is determined that the application of CHPI in the thermal scheme of heating boiler house will provide high
