The growth of renewable energy facilities worldwide creates new challenges for sustainable regional development. Unregulated investment flows in the green energy sector cause disparities in the deployment of various renewable energy technologies, worsen the ability to balance national energy systems, etc. This article is the first comprehensive study that offers a methodology for multifactor modeling of investment flows in regional green energy deployment considering the priorities of national, regional, and local authorities within the sustainable development concept. The proposed methodological approaches help (1) determine the types of renewable energy technologies for priority development in the region, (2) select specific green energy projects to receive budgetary support on territories, and (3) form the optimal mechanism for budget financing distribution on regional development of renewable energy technologies. The modeling factors include natural conditions and resource base of a territory; its economically feasible renewable energy potential; the territory’s energy needs; installed capacity and electricity generation of new green energy facilities; power plants’ life cycle duration, the investment amount, etc. The model approbation on the example of household solar and wind power plants in the Sumy region, Ukraine, has shown the need to significantly increase financial support for renewable energy projects, primarily due to the region’s energy deficit. Calculations revealed that the interest-free loan share for both technologies should be 2.843 and 2.844 times higher than the basic share of lending (20%). For the 30-kW solar power plant project, the indicator should be 64.67% instead of the basic one of 56.86% for home solar energy facilities. Thus, the methodological approaches presented in the article are new tools that allow territorial authorities to purposefully shape and manage investment flows in the renewable energy sector to ensure sustainable energy development of regions worldwide.

Utilization of landfill gas for electricity generation should be an attractive option for Ukraine in light of the country’s rapidly growing municipal solid waste problem, the influx of intermittent renewable electricity into the national grid, and renewable energy adoption commitments. However, the deployment of landfill gas power plants has been slow vis-à-vis other alternative energy technologies despite the existing government incentives. This article aims to help understanding this trend by investigating the economic feasibility of landfill gas power plants. The research focuses on determining the Levelized Cost of Electricity of these electricity generation facilities and comparing it to the feed-in tariff available to landfill gas electricity producers. The results show making an investment into a landfill gas-fired power plant is an appealing strategy due to a potential high and quick return on investment at 5.1 years. This leads to the ultimate conclusion that economic feasibility is not a cause for the slow adoption of landfill gas as a source of renewable electricity generation in Ukraine. In addition, the article identifies several potential barriers to landfill gas electricity generation deployment to be investigated in future research.

“…It should be noted that among the range of renewable energy technologies, the most suitable for usage by universities is solar energy, as photovoltaic panels can be placed on the walls and roofs of buildings (Kurbatova et. al., 2020;Sineviciene, et.…”

The paper considers the main components of the green university concept, the foreign experience of environmental transformation of higher education institutions, and the impact of eco-innovations implementation on strengthening universities' position in the UI GreenMetric World University Rankings. The green strategy of Sumy State University, the results of its implementation, and prospects for improvement in terms of increasing renewable energy sources usage through the solar power plant installation are analysed. The effectiveness of the solar power plant investment project and the reduction of carbon dioxide emissions into the atmosphere by replacing conventional electricity with electricity generated by the solar power plant are estimated. It is proved that in addition to economic and environmental benefits, the implementation of the solar energy project will positively impact the university's image at the national and international levels.
