South Europe: Cooperation in the Mediterranean - energy issues

U energy dependency stood at 44% in 1995; it will increase by 65% by 2025 and even by 80% for gas. Nuclear energy (mostly  in  France)  and  oil  production  in  the  North  Sea  (which  is  depleted)  less  and  less  cover  the  continent’  needs. According to the European plan on climate change adopted by the European Parliament on December 2008, Member States  should  reach  20%  renewable  energy  in  their  energy  mix  in  2020,  reduce  their  CO2 consumption  by  20%  and improve their energy efficiency by 20% (“20-20-20 targets”). However the path is unclear, because the Commission does not state exactly how binding these targets are. As a matter of fact, Member States do not agree on energy transition (in Germany the more nuclear power falls the more coal rises), nor on shale gas, nor on any common view on energy imports namely from Russia. Without a common energy policy, is it possible for EU Member States to adopt a common strategy vis-à-vis other global partners as Russia on any given matter?
