EU Energy Security Policy in the Face of the Russian-Ukrainian War

The war conflict in Ukraine highlighted the importance of energy security for the functioning of national economies and the European Economic Area, and especially the high degree of dependence of the European Union on imports of Russian energy raw materials, mainly gas and transmission infrastructure. The EU’s energy policy therefore required rethinking, revision and taking decisive and quick actions. The general aim of the article is to indicate and assess the impact of the energy crisis in the context of war conflict in Ukraine on the EU’s energy security policy. However, the specific objective is to present EU decisions and actions within the framework of the redefined energy policy assumptions and identify the short-term effects of the above decisions. It should be stated that under the revised EU energy security policy, reactive actions of the entire Community and national energy policies have led to the achievement of the assumed short-term goals, although it is not possible to achieve a complete change in the energy mix in a short time. The Community faces greater challenges in implementing medium- and long-term objectives. The article is part of the discussion on shaping the European Union’s energy security policy and assessing the effectiveness of its instruments in the short and medium term.
