Abstract: The issue of energy security and energy independence of the EU is one of the key factors in ensuring the stable development of the association. The subject of the study is the energy concepts of the European Union. The object of the study is the modern energy policy of the EU countries. The countries of the European Union are among the world's largest importers and exporters of energy resources, and therefore one of the criteria for EU energy security is the creation of secure logistics chains for uninterrupted energy supplies, since this factor has always been one of the most important problems in energy security. However, despite all the data that the European Union has, this area is a source of numerous problems for ensuring energy security that the EU faces at the current stage of its development. The methodological basis of the study is a systematic analysis and a geo-economic approach. The systematic approach was used in the work to identify the reasons for the transformation of EU energy concepts in the context of the energy crisis. The geo-economic approach allows us to qualitatively consider this issue from the point of view of economics and geopolitics of the countries of Eastern and Western Europe in the context of energy transition. The novelty of the research lies in the comprehensive analysis of the concept of energy security in the complex in the context of energy transfer. The authors pay special attention to the analysis of the energy policy of the European Union, numerous new initiatives and documents related to this area, as well as the development of the concept of green energy. The authors highlight the challenges that the EU will face on the way to building a stable and safe energy sector. The paper also examines the impact of the EU's energy policy on the concept of European unity. Attention is being paid to the EU's attempts to diversify energy supplies, which plays an important role in the context of the Ukrainian crisis and complications from the loss of Russian supplies. The authors conclude that the lack of internal unity within the EU does not allow for an effective and sustainable energy policy, since the European Union does not have a common energy legislation, and infrastructure development between the countries of Western and Eastern Europe is overly diversified, which does not allow us to talk about the transformation of energy policy in the EU countries at the present stage.

Abstract: The subject of the study is the migration situation in EU. Against the background of global socio-economic transformations, the EU is facing multifaceted problems in managing migration processes, acting as one of the most attractive areas of modern migration. Mass migration flows are a natural companion of globalization and the policy of openness promoted by many States. The purpose of this article is a comprehensive analysis of migration processes in the EU, focusing on the theoretical foundations, dynamics and current issues. Special attention is paid to the transformation of migration legislation in the EU member states in the period 2020-2023. The revealed data on new migration projects in the EU countries make it possible to trace the dynamics of changes in official EU legislation on this issue and formulate proposals for resolving the crisis situation. The methodological basis of the research is a systematic approach and the theory of multilevel management. The systematic approach was used in the work to identify the causes and consequences of the transformation of EU migration legislation within the framework of an integrated set of migration processes. The theory of multilevel management considers the issue both at the national level and at the level of the European Union. The novelty of the research lies in the development of scientific discourse on migration processes in the European Union. An in-depth analysis of migration dynamics in the EU, and as a result, the reasons for the transformation of migration legislation, expands the understanding of migration control mechanisms, and also evaluates the participation of EU member states in the formation of migration policy. The research contributes to the awareness of the interactions between migration and other socio-economic processes, which is significant for the academic community and the creation of educational programs. The practical significance of the study lies in its contribution to the formation and improvement of the EU migration policy. Based on the collected data and analytical conclusions, recommendations can be made to improve the current mechanisms of migration management, strengthen integration processes and maintain social balance.
