Renovating the European Union energy system and reducing excessive dependency on Russian imports requires a commitment to saving, diversifying supplies, and the use of renewable sources.The European Union is facing one of its biggest energy challenges in 2023. In a crisis context caused by the war in Ukraine, with price increases and limitations in supplies caused by the conflict, it is essential to make adjustments to the European Union’s energy system in order to solve some of its most pressing shortcomings. In particular, its heavy dependence on imports of gas, oil, and coal from Russia, a supply with few guarantees due to the current situation, and which leaves many member countries facing a complicated supply situation in the short term.  To solve these matters and mitigate the negative effects of the war on energy, the European Commission launched an ambitious contingency plan in May 2022 called REPowerEU. An agreement that includes different measures aimed at ensuring the supply of energy to all citizens, as well as starting the transition towards an energy system in Europe, not only more independent and stable, but also more sustainable.  REPowerEU Plan The main aim of the plan is to reduce the reliance of states on Russian fossil fuels, such as oil, coal, and gas. This agreement seeks to completely renovate the traditional energy system of the Union, incorporating reforms from the ground up and seeking to achieve a twofold objective. On the one hand, to no longer depend on supplies from Russia — currently at risk due to the sanctions imposed on the country — and on the other hand, to seize the moment to accelerate the transition to clean and sustainable energy. In this way, not only would it end Russian trade relations regarding fossil fuels, but it would also be essential to replace this supply with renewable energy alternatives that help to meet the climate-neutrality objectives set.  In order to achieve this twofold objective, it is important to bear in mind that not all member countries are in the same energy situation. It depends on their degree of dependence on Russia, their possibilities to access other energy options, or the interconnections and infrastructures they have in place for this purpose. Taking these factors into account, the measures proposed in the REPowerEU plan are always based on the principles of solidarity and equity among countries, favoring cooperation among them to avoid inequalities that may arise during the transition period.  Areas of action The REPowerEU Plan is based on the Fit for 55 packet of measures presented in 2021, adapting them to the current energy situation and emphasizing decision-making on four basic pillars. Energy saving. Diversifying supplies. Replacement of fossil fuels with renewable energies. Intelligent combination of investments and reforms.
