The European Union's prosperity and security notably depends on a stable and continuous energy supply system. The trend of  increasing import dependency has reached more than 50% in recent years, according to the in depth study of European energy security published in July 2014 by the European Commission.

Due to the evolution in the geopolitical context and in order to prevent potential disruptions to energy supplies, the G7 Energy Initiative agreed on core principles on the 6th of May 2014. Following the Council request for a  European strategy for energy security, on 28 May 2014 the European Commission published a communication concerning the EU Energy Security Strategy. The Commission's communication aimed at putting forward a series of short-term actions in order to both check how Europe's energy system can cope with risks to security of supply and to develop emergency plans and back-up mechanisms... In addition, the Commission’s Communication indicates areas in which “concrete actions need to be implemented in the short, medium and longer term” in order to increase energy efficiency, diversify supplier countries and routes, and  complete the internal energy market, by building missing infrastructure links and strengthening emergency, security and solidarity mechanisms.

The European Council of June 2014 also confirmed that energy security should be inherent to the 2030 policy framework on climate and energy. The appointment of a Vice President to the European Energy Union in the new European Commission poses several questions on how the EU will pursue its commitments on these domains: will the energy security issue give further momentum to the process of integration of the European energy market? Will the current 2030 energy and climate change policy effectively tackle the issue of energy security? Or is energy security the weak link of the EU energy and climate change policies?
