It is no wonder anymore that the European Union (EU) energy norms have gained extraterritorial dimensions. Thanks to global processes on environment and climate change, ‘EU energy law and policy’ has now developed from a notion used by a small section of European society into a hot topic beyond the EU’s formal bounds. The recent Eurobarometer report reveals that nine in ten Europeans call for the EU to engage actively in foreign energy relations and ensure access to affordable energy. By the same token, the last couple of years have seen a growing interest in the Energy Community as a key legal vehicle to spread EU energy rules and principles across South East Europe. But what does it entail? This is exactly what the blogpost tries to untangle, shedding a light on the EU’s external energy competence and the role of the EnC in promoting green energy transition.
