BACKGROUND AND OBJECTIVES: The new wave of the Covid-19 pandemic has complicated the working conditions of higher education institutions in Ukraine. In this regard, saving energy resources of the university offers an opportunity to get out of the crisis. The purpose of the study is to develop a management system for energy complexes with non-conventional renewable energy sources in the context of preventing a new outbreak of Covid-19 pandemic.METHODS: The method of Deutsche Gesellschaft für Nachhaltiges Bauen was used to conduct energy audits, construct energy profiles of university offices. The cluster analysis was used to perform energy certification of university offices according to the indicators of integral energy efficiency potential and the level of annual specific energy consumption. Fuzzy methods made it possible to classify all the buildings into 3 categories (A, B, C) to prioritize their use in the light of Covid-19 pandemic. The system for monitoring the attained level of energy efficiency is based on the use of discriminant analysis.FINDINGS: Implementation of the weighted strategy has proved that the classes will be given online, 23% of all offices. Category A (administrative, technical, service buildings; laboratories with unique equipment with 24-hour service) will be used in a pessimistic scenario (continuation of Covid-19 pandemic). In the optimistic scenario (end of Covid-19 pandemic), by means of the suggested energy efficiency monitoring system, the probability of using category A offices makes 100%, B offices- 50% and C offices - 13%.CONCLUSION: Implementation of the developed energy efficiency action plan will offer the opportunity for the University to use reasonably the common connection point of knowledge management of energy complexes with non-conventional renewable energy sources in the context of preventing a new outbreak of the Covid-19 pandemic. The profitability of implementing a weighted energy efficiency strategy is 15%, with a payback period of 6.7 years for the purchase and installation of non-conventional renewable energy equipment. In the future, it would be advisable to convert gradually all of the remaining 14 university buildings to the autonomous use of non-conventional renewable energy sources, using a common connection point for the knowledge management of the energy complexes.

BACKGROUND AND OBJECTIVES: Environmental guidelines and principles of sustainable development are becoming increasingly popular and are a priority for most business areas. One of the widely developing eco-destinations is green tourism, which is gaining a profitable and priority status, especially for lower middle-income countries. The purpose of the article is to determine the strategic marketing support for the development of green tourism on the example of Ukraine and its regions based on an approach to its assessment in terms of environmental and tourism competitiveness.METHODS: The authors used general scientific and specific methods: comparative, critical and system analysis, synthesis to search and group indicators of ecological and tourism competitiveness. Distance method, ranking, economic and statistical analysis were implemented to analyze the green tourism potential in each region in Ukraine and reveal the leaders and outsiders among them. For the accumulation, processing, visualization of data and forming the matrix of green tourism, based on data for 2015-2019, potential Microsoft Excel, Figma and Canva tools, Harrington scale were applied.FINDINGS: The approach to estimate the green tourism potential based on the ecological and tourism regional competitiveness according to the author’s list of 37 indicators were proposed, the matrixes of green tourism potential of Ukrainian regions in 2019 and 2020 were developed, and strategic marketing support according to sustainable development for green tourism business were proposed. Strategic marketing support of green tourism development in Ukrainian regions was defined based on ecological and marketing strategies.CONCLUSION: The author's approach makes it possible to systematically assess the potential of green tourism using up-to-date statistical information. According to the tourism and environmental competitiveness rating, the regions with the most significant and worst potential were found. The positive dynamics of the development of green tourism in 2019-2020 were revealed. The results are the basis for providing comprehensive environmental and marketing support to ensure sustainable development and gain additional competitive advantages in the green tourism business.

This study provides a comprehensive scientific analysis of contemporary problems resulted from the forced migration of the Ukrainian population and its impact on the sustainable development of 47 host communities of Poltava region. By means of cluster analysis 4 clusters of 26 rural territories were identified. They differ in the size of local budgets and the involvement level of forcedly displaced population into the local economy. Factor analysis showed that the involvement level of forcedly displaced population in the region's economy is determined by 2 groups according to 10 indicators. 8 indicators of the first factor determine 2/3 of the dispersion of refugees' impact on rural economy. The first factor reduces the gross regional product by 61.75%. The indicators of the second factor shows a positive impact and determines 15% of the dispersion. The use of game theory to identify conflicts of interest between refugees and host communities was justified. The reasonability to use the taxonomy method to construct a map of positioning rural areas according to the size of local budgets and the degree of integration of refugees is justified. The use of the created map identified the “growth points” in particular clusters. As a result of the implementation of the proposed conflict resolution mechanism between refugees and host communities, the budget of the rural areas of the first cluster increased by 18%, the second cluster by 14.5%, the third cluster by 13%, the fourth by 8%, refugee participation by 30%.

The study highlights the importance to develop the national economy through assuring energy security. The study aims to analyze how to develop renewable energy sources, determine the main priorities of Ukraine’s national security policy and discover novel ways of assuring energy security due to developing the industry of renewable energy in the light of environmental safety, energy conservation, and efficiency. The following scientific methods were employed: synthesis and analysis – to determine the essence and significance of RES in order to assure energy security; theoretical generalization – to single out the main stages of renewable energy development; classification – to classify the main advantages of introduction of RES, as well as the obstacles to their implementation; logical generalization – to justify the relevance, aim and objectives of the study; the method of rising from the abstract to the concrete – to develop and justify the ways of assuring energy security provided that renewable production is developed. The following results are obtained: the main conditions for developing RE are determined; some relevant issues of energy efficiency and assurance of Ukraine’s energy security are justified; significant potential of Ukraine’s renewable energy industry is discovered and analyzed; target values Ukraine seeks to achieve with the help of the energy generated from RES in final energy consumption are analyzed; the main criteria for developing Ukraine’s fuel and energy complex are revealed and the key branch ratio values of the state’s energy balance are determined.
