The European Union faces significant challenges in energy policy, especially in the context of the transition towards renewable energy sources and reduced dependence on fossil fuels. The global energy crisis, triggered by various factors including geopolitical tensions and climate change, demands an appropriate and efficient response from member countries. One of the European Union’s main steps is the implementation of the European Green Deal, which aims to achieve net-zero emissions by 2050. This policy encourages investment in clean energy technology, energy efficiency and the development of green infrastructure. One important aspect of the Green Deal is the increased use of renewable energy, such as wind, solar and biomass. By strengthening the capacity of renewable energy sources, the European Union hopes to reduce dependence on natural gas and oil, most of which are imported from countries outside the EU. Apart from that, the issue of energy supply security is also a major concern. The Ukraine crisis has demonstrated the EU’s vulnerability to fluctuations in energy supplies from Russia. As a mitigation effort, the EU plans to diversify energy sources and supply channels. Cooperation with energy producing countries, such as Norway and northern African countries, is part of a long-term strategy to ensure supply security. Changes in energy policy are also leading to increased investment in energy storage technologies. The development of batteries and other storage solutions is critical to maintaining the stability of the electric grid, especially as the use of renewable energy increases. For example, innovative projects using green hydrogen technology and large battery storage aim to provide a stable energy supply and help offset the uncertainty of renewable energy production. Support for innovation and research in the energy sector has now become more urgent. The European Union launched various funding programs to support research in the energy sector. The Horizon Europe Initiative, for example, provides financial support for research and development of new technologies needed to navigate the energy transition. The role of society in energy policy is also increasingly important. Public awareness of environmental and sustainability issues has increased, creating impetus for governments to implement more environmentally friendly policies. The European Union seeks to involve citizens in energy-related decision-making, creating awareness of the importance of energy efficiency and reducing carbon emissions at the individual level. Interconnection policies are also a top priority in facing this challenge. Improved electricity networks between member countries enable more efficient energy distribution, facilitate renewable energy exchange between countries, and increase the resilience of the energy system as a whole. The implementation of an inclusive and sustainable energy policy will determine the future of the European Union in an increasingly competitive context. By facing these challenges collaboratively, member countries can create a cleaner and safer path to a sustainable energy system. This broad initiative includes the integration of renewable energy sources, the creation of a more connected grid, and community engagement, which is expected to shape new opportunities for sustainable economic growth across Europe.
