The European Union (EU) has long been a pioneer in energy cooperation among its member states. With increasing energy needs and the challenge of climate change, increasing this cooperation becomes increasingly urgent. The EU established several initiatives to encourage energy solidarity across the region, including the creation of a single energy market, reducing dependence on fossil energy sources, and transitioning to renewable energy. One of the concrete steps taken is the development of an electrical energy transmission network. Projects such as the European Supergrid are considered important for connecting renewable energy generation in the Nordic countries with energy markets in Central Europe. The continuity of this network not only helps more efficient energy distribution, but also strengthens the stability of energy supplies between member countries. European Energy Policy, including the Green Deal, focuses on managing greenhouse gas emissions. This encourages member countries to invest in technologies that are less detrimental to the environment. Initiatives such as REPowerEU aim to reduce dependence on Russian natural gas and accelerate the transition to renewable energy such as solar and wind power. Through various subsidies and innovative breakthroughs, this effort increases collaboration among member countries. In addition, the Horizon Europe program funds research and innovation in the field of clean energy. It promotes research cooperation between universities, research institutes and industrial sectors of various European countries. A focus on energy storage and energy efficiency technologies has the potential to bring innovative solutions to today’s energy challenges. The European Union also prioritizes diversification of energy sources by supporting cross-border interconnection projects. By creating infrastructure that allows energy exchange between different countries, the EU strengthens solidarity between members and reduces the risk of energy supply disruptions. Projects such as the Trans Adriatic Pipeline (TAP) gas interconnection play an important role in increasing energy supplies from non-European countries. In addition to infrastructure development, the EU encourages clean and sustainable energy policies across its member countries. These policies include regulating energy use, incentives for renewable energy users, as well as promoting energy efficiency in the industrial and domestic sectors. These efforts are in line with the EU’s overall goal of achieving carbon neutrality by 2050. International collaboration is also an important part of the EU’s energy strategy. Through dialogue with non-member countries such as Algeria and Norway, the EU seeks to secure a diverse and sustainable energy supply. Such discussions focus on cooperation in the production and distribution of alternative energy sources. As the need for clean energy increases, the EU is committed to maintaining stable energy prices. Through fair energy market regulations, to prevent speculation that is detrimental to consumers, especially during the transition to renewable energy. With these steps, the EU is demonstrating its commitment to leading the way on the global energy agenda. The European Union’s energy cooperation strategy is a model that can be adopted by other regions around the world. By harnessing innovation, research and collaboration between countries, the EU is shaping a more sustainable and secure energy future for future generations.
