Energy and geopolitics are directly connected and shape each other. A very small, almost negligible number of countries can meet all their needs with their own energy sources, and depend on imports from other countries to achieve this goal. Natural resources are not only a driver of economies and an important factor in political decision-making, they are also a source of potential conflicts. This is where the scientific contribution of this paper lies, namely in order to be ready to face potential challenges, it is important to be well acquainted with the real state of energy supply in order to identify weak points and work on correcting them in time. The initial goal of the paper is just that, to show the current state of energy supply in the territory of EU member states. First, the EU's competences in the field of energy policy, energy security and the state of energy in the Union will be presented through a review of current literature. Then, two geopolitical narratives derived from the Study on Security of Energy Supply and Geopolitics will be presented. The third part will discuss double diversification, followed by a presentation of each individual member state. Finally, the question of the presence of both geopolitical discourses in the EU will be answered through the presentation of two specific projects.
