The European Union (EU) has significantly increased energy cooperation with its member countries in recent years. The resurgence of the need for clean and sustainable energy and dependence on local energy sources is driving this initiative. One of the goals is to achieve ambitious targets in reducing CO2 emissions and increasing energy security throughout the region. One of the EU’s main steps is the implementation of the European Energy Policy, which aims to create an integrated and efficient energy market. This is achieved through the development of better energy infrastructure, including electricity networks and gas pipelines. Cross-border energy projects, such as electricity interconnection between member countries, help in optimizing the use of renewable energy resources, such as wind and solar. The renewable energy sector has become the main focus of this collaboration. The European Union invests heavily in renewable energy technologies, supporting research and innovation in the sector. The Horizon Europe program, for example, provides funding for research related to renewable energy, energy efficiency and energy storage. Member countries are encouraged to participate in projects that create clean and reliable energy. Apart from that, the EU is also pushing to reduce dependence on fossil fuels. Through the Green Deal initiative, the EU has set a target to increase the use of renewable energy to 32% by 2030. This creates a huge opportunity for member countries to collaborate on the development of renewable energy projects, such as offshore wind farms and solar power plants. Cooperation on energy policy also includes energy security. The EU seeks to reduce dependence on specific energy exporting countries by diversifying sources and supply routes. By building a stronger and more integrated energy infrastructure, member countries can help each other in times of crisis, ensuring a stable and sustainable energy supply. The success of energy cooperation within the EU has also been supported by the creation of institutions such as the European Energy Agency (AEA), which oversees and promotes the implementation of energy policy at regional level. The AEA plays an important role in collecting data, conducting analysis, and providing recommendations to member countries regarding energy policy. In addition, the EU stimulates collaboration between the public and private sectors to increase investment in clean energy. Innovative financing schemes and tax incentives are promoted to attract investors into sustainable energy projects. Cooperation between member countries can create better market opportunities, reducing project costs and risks. The initiative to create an “Energy Union” is also a major focus. Through this approach, member countries are expected to work together in developing long-term strategies to face global energy challenges. Collaboration in research and development, as well as technology exchange, are key components of this vision. Interdependence in energy cooperation not only increases efficiency, but also builds solidarity among member countries. When faced with global challenges such as climate change and the energy crisis, the collective approach taken by the European Union can provide more effective and sustainable solutions. Through these initiatives, the European Union is demonstrating its commitment to be a leader in the global energy transition, creating a greener and more energy efficient future for all its member countries. The existing cooperation further strengthens the European Union’s position on the world political and economic map, while also providing a positive impact on the environment and society.
