The scientific novelty presented in this paper is to substantiate the extension of the resource potential of renewable energy sources in the Carpathian region with the creation of a set of maps in the geographic information system “Map Info”. For each type of renewable energy (solar, wind, small hydropower) a number of technical issues and advantages, technological ecologically safe priorities are defined. The detailed regional calculation of wind, solar, hydropower potential for the Carpathian region of Ukraine has been performed. The spatial limitations and possibilities of introducing renewable energy sources in the sustainable development of the region are scientifically substantiated. Renewable energy scenarios are proposed.

The theoretical and methodological foundations of sustainable development of Geosystems were further evolved. It was grounded the new scientific direction "constructive Hydroecology" - the science that studies the Hydrosphere from the standpoint of natural and technogenic safety based on geosystematical approach. A structural separation for constructive Hydroecology based on objective, subjective, and application characteristics was set. The main object of study of the new scientific field is the hydroecological environment under which the part of Hydrosphere should be understood as a part of the multicomponent dynamic system that is influenced by engineering and economical human activities and, in turn, determines to some extent this activity.

The use of renewable energy in sustainable tourism development of the region is grounded in the paper. There are three stages of selecting areas for projects of renewable energy sources: selection of potentially suitable area; consideration of exclusion criteria, detailed assessment of potential sites or areas. The factors of impact on spatial constraints and opportunities for building wind, solar and small hydro power plants on the parameters of sustainable tourism development in the Carpathian region were determined.
