The European Union (EU) faces major challenges in overcoming the increasingly urgent energy crisis. For this reason, green policies are a strategic choice in creating energy security and maintaining environmental sustainability. This policy includes various initiatives and concrete steps aimed at reducing dependence on fossil energy sources and encouraging the use of renewable energy. One important step in green policy is the implementation of a sustainable energy strategy. The European Union has set an ambitious target to reduce greenhouse gas emissions by at least 55% by 2030 compared to 1990 levels. This policy does not only focus on the energy sector, but also covers transport, industry and land use. Investment in renewable energy is becoming a key component of green policy. Energy from sources such as wind, solar, and biomass is promoted as a cleaner and more sustainable alternative to fossil fuels. The European Union is committed to increasing the share of renewable energy in total energy consumption, reaching 40% by 2030. This step is complemented by financial support for member countries to build the necessary infrastructure and technology. The European Green Deal initiative is also playing an important role in confronting the energy crisis. Through this, the EU seeks to decarbonize its economy and ensure that economic growth does not harm the environment. The program includes financing projects that support innovation in green technologies and workforce training to prepare for the transition to a low-carbon economy. In addition, the EU is also focusing on improving energy efficiency. The efficiency program aims to reduce energy consumption in various sectors, including buildings and transportation, through the implementation of stricter standards. This not only reduces emissions but also reduces energy costs for consumers. The EU’s green policy also encourages international cooperation in the energy sector. For example, cooperation with neighboring countries to develop a more integrated renewable energy network can strengthen energy security. By sharing resources and technology, the EU can optimize the use of renewable energy across the region. The use of innovative technologies, such as energy storage and smart grids, is becoming an integral part of green policy strategies. This technology enables storage of volatile renewable energy and ensures efficient distribution. In addition, digitalization of the energy sector helps energy consumers and producers to manage consumption and production more effectively. Climate change and the energy crisis are interrelated, so the EU’s green policies also address the long-term impacts of fossil energy dependence. By switching towards clean and renewable energy sources, the European Union not only contributes to environmental protection but also creates new jobs and increases global competitiveness. The EU’s adoption of green policies demonstrates its commitment to creating a sustainable and resilient future. By implementing this policy, the European Union seeks to be a leader in the global energy transition, creating a model that other countries can follow in facing similar challenges.
