CAIS-Forscherin Dr. Tetiana Gorokhova ist Co-Autorin des Open-Access-Artikels „Green Economy and Energy Transition: Economic Models for Integrating Renewable Energy in Eastern European Countries“, der im ITEGAM Journal of Engineering, Technology and Industrial Applications wurde. Angesichts der Herausforderungen des Klimawandels und der Dekarbonisierung beleuchtet die Studie die strukturellen Bedingungen der Energiewende in Osteuropa. Auf Basis von Energiebilanzen aus den Jahren 2022 bis 2024 zeigen die Autorinnen, dass fossile und nukleare Energieträger zwar zur kurzfristigen Stabilität der Energieversorgung beitragen, zugleich jedoch die Integration erneuerbarer Energien und die langfristige Transformation der Energiesysteme erschweren.
Abstract
Global energy systems are currently undergoing a fundamental transformation with an active transition from fossil fuels to renewable energy sources. Fueled by the fight against climate change and emissions, the energy transition has become a major challenge for the global economy. In this context, the inclusion of renewable energy sources in the energy balance is becoming a strategic way to promote further economic transformation. The aim of this scientific article is to analyze the structural features of the energy transition and assess the degree of integration of renewable energy through digital technologies into the overall energy balance compared to fossil fuels in Eastern European countries. The article provides an empirical analysis of simplified energy balances of Eastern European countries for the period 2022–2024. For this purpose, independent and dependent variables of the analysis were calculated, which made it possible to form descriptive statistics, perform correlation analysis, and conduct multiple linear regression. Results. Model M1 has greater explanatory power (R² = 0.533; Adjusted R² = 0.471) and is statistically significant (F = 8.567, p = 0.003), unlike model M0, which explains only 1.3% of the variance in the share of renewable energy (R² = 0.013) and is statistically insignificant (F = 0.219, p = 0.646). This proves that dependence on fossil fuels or nuclear energy is associated with a smaller share of renewable energy sources in the national energy balance. Dependence on fossil fuels and a significant share of nuclear energy serve two purposes in the energy systems of Eastern European countries, among other things: they ensure short-term stability of energy supply while structurally slowing down the pace of integration of renewable energy sources, thereby limiting the possibilities for diversification and transformation of the energy balance. Therefore, a promising avenue for research is the development of integrated energy policy models that reconcile the stabilizing function of fossil and nuclear energy sources with long-term decarbonization goals.
