The European Union (EU) said on Friday it would reduce Europe's high gas dependency rates to the external markets, notably on Russia, said a conclusion adopted by the EU summit. "Reducing our energy dependency, especially with Russia, was a key topic in our deliberations,"European Council President Herman Van Rompuy told the press conference following the summit. The European Council called on the Commission to conduct an in-depth study of EU energy security and to present by June 2014 a comprehensive plan for the reduction of EU energy dependence. It requests the plan should reflect the fact that the EU needs to accelerate further diversification of its energy supply, increase its bargaining power and energy efficiency, continue to develop renewable and other indigenous energy sources and coordinate the development of the infrastructure to support this diversification in a sustainable manner, including through the development of interconnections. It also requests the member states to show solidarity in case of "sudden disruptions" of energy supply in one or several member states.
