Recently, top EU leaders announced the establishment of the Energy Union. This should be the creation of an integrated energy policy for the entire European Union, which is currently lost somewhere between environmental policy, competition, industry and climate change. Before us is a period when a number of important decisions will be taken in the field of energy. The Informal Energy Council scheduled for next week will also see Ministers of the Member States discuss this new initiative. Therefore, I suggest to look at some key information and basic concepts to shed some light on the matter.
