The article is devoted to research and comparison of approaches to ensuring energy security in the European Union (EU) and Ukraine. The article analyzes the main aspects of energy security, such as ensuring energy independence, stability and sustainability of the supply of energy resources, the development of energy efficiency and the use of renewable energy sources, integration into a single energy space, as well as the challenges faced by both sides. The article highlights similarities and differences in approaches to ensuring energy security. Among the common aspects is the recognition of the importance of energy security and the significant attention paid to it by both parties. Both sides are also working on diversifying supply sources and improving energy efficiency. At the same time, there are differences in the development of energy infrastructure and access to resources, where the EU has a developed and diversified system, and Ukraine faces challenges and limitations. The article examines the prospects for the development of the energy sector in both contexts. The EU aims to ensure a stable, stable and sustainable supply of energy resources through the development of a single energy market and cooperation with other countries. Ukraine also has the potential to develop its energy sector, particularly in the field of renewable energy, which can contribute to reducing dependence on imports and ensure a stable and sustainable energy supply. Ukraine's integration into the single energy space of the EU and support and investment from the EU for the development of Ukraine's energy sector are considered important. The article also provides the necessary steps to ensure energy security in Ukraine. Among them, it is worth highlighting the modernization of the energy system, cooperation with the EU and other countries, diversification of supply, improvement of energy infrastructure, increasing energy awareness of the population and harmonization of legislation with European standards. Different research methods were used to obtain reasonable results. The article analyzed the official documents and strategies of the EU and Ukraine related to energy security. This analysis made it possible to identify the main principles and approaches used in each of the concepts. The article is supported by a review of current scientific research and publications on energy security that relate to the EU and Ukraine. This literature review identified key aspects and trends in the field. Deduction and induction methods were used for comparative analysis. The application of the deduction method made it possible to proceed from the general provisions and principles formulated in official documents to derive specific conclusions regarding energy security. With the help of the induction method, an analysis of specific facts and data was carried out, from which generalizations and the formulation of general conclusions were made. The general conclusion of the article is that both the European Union and Ukraine strive to ensure energy security, but their approaches and priorities may differ. The challenges facing both sides require continued effort and cooperation to achieve a sustainable and sustainable energy future.
