Item Factor Analysis Of Energy Security: Net Import Dependency(Sumy State University, 2022) Колосок, Світлана Іванівна; Колосок, Светлана Ивановна; Kolosok, Svitlana Ivanivna; Коваленко, Євген Володимирович; Коваленко, Евгений Владимирович; Kovalenko, Yevhen VolodymyrovychThis paper analyzes various aspects of energy dependency and identifies the hidden factors behind national energy security. Based on a review of the scientific literature, the factors that reduce energy security in the consumption of natural gas, oil, and nuclear energy generation were identified. One such factor is import dependency on energy resources. Import dependency on energy is a crucial characteristic of energy security and can exacerbate the effects of external aggression, non-competitive behavior, and pressure. Given the energy crisis of 2022, most countries around the world have revised their energy security policies to reduce import dependency by diversifying supplies and reducing dependence on Russian energy resources. The factor analysis of energy dependency ratios, 1990-2020, was used to study the energy security of the EU27 countries. The factor analysis was performed for annual indices calculated using the Eurostat database of “Simplified energy balances.” The paper hypothesized the existence of latent relationships between energy security variables for the twenty-seven EU countries. The hypothesis was verified using Bartlett’s sphericity test and Kaiser-Meyer-Olkin criterion. The results of hypothesis testing showed its statistical significance (the p-value < 0.05) and the possibility of factor analysis. Correspondence indices also indicated the adequacy of possible prediction of a set of variables. The factor analysis was executed in Python using the FactorAnalyzer module (the release 0.4.0). The principal factor extraction and the varimax rotation model were used to obtain the initial solution, preserving the orthogonality of the loading matrix. The factor structure of the model was confirmed for four factors consisting of the twenty-eight elements. The received four factors model allowed us to describe around 80% of the cumulative variance. It was found that each factor separately explained 46.89%, 15.80%, 10.91%, and 6.39% of the variance, respectively.Item Regularities In The Development Of The Theory Of Energy Efficiency Management(Sumy State University, 2021) Зябіна, Євгенія Анатоліївна; Зябина, Евгения Анатольевна; Ziabina, Yevheniia Anatoliivna; Коваленко, Євген Володимирович; Коваленко, Евгений Владимирович; Kovalenko, Yevhen VolodymyrovychThis article summarizes the arguments and counterarguments within the scientific discussion on the laws of developing the theory of energy efficiency management of the national economy. The study’s primary purpose is to develop theoretical and methodological tools for analyzing the patterns of development of the theory of energy efficiency management of the national economy. Systematization of literature sources and approaches to solving the problem of developing the idea of energy efficiency management of the national economy has shown a need to update state energy policies, strategies, regulatory and legal support for the energy sector’s functioning.Item Energy Efficiency Of National Economy: Social, Economic And Ecological Indicators(Sumy State University, 2020) Зябіна, Євгенія Анатоліївна; Зябина, Евгения Анатольевна; Ziabina, Yevheniia Anatoliivna; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Старченко, Людмила Володимирівна; Старченко, Людмила Владимировна; Starchenko, Liudmyla VolodymyrivnaThe paper aimed to formalise the relationship between the level of Ukrainian energy efficiency from 30 indicators of social, ecological and economic development of the country. The main purpose of the study is to identify the impact and dependence of socio-ecological and economic indicators on the level of energy efficiency using multiple correlation-regression analysis. The systematisation of the analysed results allowed identifying the core directions to overcome the issues of the slow pace of energy efficiency improvement and the development of carbon neutrality of the country. TItem Modification of the International Energy Agency Model (the IEA Model of Short-term Energy Security) for Assessing the Energy Security of Ukraine(Sumy State University, 2017) Salihaj, T.; Pryimenko, S.Over the past decades, as a result of global environmental, energy and economic crises, the level of development of the fuel and energy complexes in the world has become one of the dominant factors determining the level of national security, the country’s competitiveness in the world market and its economic stability. At the same time, today the level of environmental and natural and technogenic safety of energy companies is extremely low in the world. Taking this into account, scientists and representatives of state authorities of various countries of the world, as well as intergovernmental as-sociations and international organizations discuss the problem of searching for innovative sources of electric power generation for obtaining new types of energy products that can change innovative sources of electricity production and the global economy as a whole, and will increase the rationality of resource use and environmental safety of the country, regions and people.Item The impact of “policy paradigms” on energy security issues in protracted conflict environments: the case of Cyprus(Sumy State University, 2017) Karakasis, V.P.The research question that this article attempts to address is: what are the main policy paradigms that guide the opinion leaders throughout energy security matters within protracted conflict environments? Using the de facto divided island of Cyprus as our single case study, we will deliberately follow grounded theory in order to create conceptual definitions out of rudimentary “working ideas” that involve “protracted conflict environment”, “energy security” and stakes in “decision making”. This research enterprise involves openended interviews with the opinion-makers on the Island and “political discourse analysis” that identifies the quintessential aspects of the recently emerged energy debate. Drawing upon the work of Correlje and van der Linde (2006), we highlight two main paradigms: “markets and institutions” and “regions and empire”. In the first one, the business logic prevails upon political expediencies and geopolitical calculations, while in the second one, national and security concerns outweigh the business logic and the potential international economic integration. Through their interaction, we seek to explore how they drive the debate on energy security within the realm of a conflict environment.
