What impact will volatile energy prices have on European prosperity? What are the EU's real priorities within its energy policy, and what should they be? Does a common approach to energy policy make sense, given the structural differences between national energy markets? Is a fully integrated European energy market a necessary condition for a common European energy policy? Is it feasible at all? How far should integration of energy policies go? How economically and environmentally sustainable is Europe's energy supply? What trade-offs does EU energy policy have to reconcile? How dependent is Europe on Russian gas and oil? What is the relationship between today's geopolitical conflicts and energy supply security? What are the future spheres of conflict? Does the EU have viable choices and how costly are they?
