Given the strong dependence of many European countries on Russian gas and oil exports, the war in Ukraine has created fundamentally new conditions for the European energy policy leading to calls and first steps (such as the scrapping of the North Stream 2 pipeline) to reduce this dependence. The seminar addresses dependence issues, as well as debates on the impact of the war to the transition to renewable energy sources, the redirection of trade from Russia to other providers, and the role of nuclear power (with potential divisive effects both between and within member-states).
