The European Union (EU) continues to increase energy cooperation with its member countries to face emerging challenges in the energy sector. In an increasingly diverse global context, this collaboration is crucial to ensure energy security, sustainability and the transition to renewable energy sources. Through various initiatives, the EU seeks to create an integrated energy market and improve energy infrastructure across the continent. One of the main steps is the development of Joint Energy Projects (PEB), which involve investment in energy distribution and transmission infrastructure. This allows member countries to share resources and technologies, such as the use of smart electricity grids that can optimize energy distribution. The PEB also includes interconnection projects that connect member countries to increase the stability of energy supplies. In regularly held energy summits, leaders of member countries discuss strategies to accelerate the use of renewable energy. For example, the Green Europe program (Green Deal) aims to make Europe the first carbon neutral continent by 2050. This stimulates investment in solar, wind and biomass energy, and supports technological innovations that make the transition more efficient. Cooperation in gas utilization is also a major concern, especially regarding dependence on energy imports from third countries. Projects such as the Southern Gas Corridor aim to increase diversification of gas supplies and reduce dependence on Russia. In addition, the EU encourages member states to strengthen gas distribution networks to support access to local energy markets. Digitalization of the energy sector also receives great attention in this collaboration. Member countries are invited to adopt digital technology that can increase efficiency in energy management and distribution. The use of data analytics and artificial intelligence in energy management helps member countries monitor supply and demand more accurately, reduce waste and minimize environmental impact. At the same time, the EU continues to strive to strengthen energy security policies through multilateral and bilateral cooperation. Energy dialogue with non-member countries, including large energy producing countries, is important to ensure continuity of supply and price stability in the global energy market. This initiative includes collaboration in research and innovation to find new solutions in energy development. Capacity building is also a focus, with the EU providing training and technical support to member states in designing sustainable energy policies. These programs aim to strengthen national capabilities in overcoming energy challenges, such as climate change, as well as ensuring affordable energy access for all levels of society. Through all these steps, energy cooperation in the European Union is not only about managing resources, but also creating synergies between member countries to achieve the ambitious targets that have been set. With a collaborative and innovative approach, the EU seeks to ensure that all its members can adapt to the dynamics of global energy change and lead in the transition to a more sustainable future.
