For a while now the energetic sector that is of vital importance for the economy has become a battle field where political and economic interest collide.
Currently EU economy imports 52% of its energy, however by 2020 the enlarged EU (30 countries) are expected to import 78%. Oil and natural gas are of key importance. Growing gas consumption in Europe in the next two decades would be almost totally covered from Russian exports, which would double to EU. There are plenty of examples in history when such a heavy reliance on imports from one single country was exploited by that country as a virtual means to wield pressure or exert strategic political threats. Hence, in the last 30 years various oil crises, regional conflicts and errors in domestic energy policy have been quite illustrative of the strategic and political importance of energy source.
