Abstract

Energy security is one of the key sectors of security of modern states, the basis for their efficient functioning, development and economic capacity building. Before the invasion of Ukraine in 2022, the Russian Federation was one of the main suppliers of energy resources to Europe. The outbreak of war forced European states to redefine their energy policies and to diversify their sources and suppliers. The article analyses, based on academic studies, legal acts, international reports and internet sources, the impact of the war in Ukraine and the sanctions imposed on the Russian Federation on energy security in Europe.
