Abstract
Ensuring the energy resources needed for the functioning of society as a whole is a major concern for European countries, which must identify solutions in this regard. Measures to be taken individually and collectively aim to ensure a continuous flow of energy resources and to consolidate the energy security. The energy security of European states is quite difficult to achieve due to the energy situation of all states and due to the increased dependence on energy resources outside the European space. Ensuring energy security not only creates the conditions for the development of society, but also strengthens national security, as it eliminates possible sources of tension and contradictions, which can lead to crisis or even conflict. From this perspective, it is clear that the EU is making efforts for energy sources diversification and to reduce the likelihood of malfunctions, but the evolution of the energy situation of the EU bloc shows that this is a long-term approach and concrete measures are very difficult to implement, fact easy to notice from the analysis of the energy situation of the EU between 2014 and 2018.
