This dissertation aims to clarify how and to what extent energy can be found in the center of a war / conflict. This happens due to economic, political, and geostrategic factors; according to the aspirations of the respective states, governments, paramilitary organizations or simply conjunctures. The new era of the war is more affiliated to a possession of unconventional military equipment, strategies and unorthodox attacks. It is obvious that the conflicts between (inter)state and non-state factors are becoming more and more common and frequent, in example conflicts among global (super)powers, -which are being considered as a part of international system-, sovereign states, which try to put a lot of effort on the non-military aspects of power and security escalation. “In the modern era, conventional methods of warfare are generally complemented with techniques of insurgency, terrorism, sabotage, subversion and information warfare” (U.S. Department of the Army, 2008).
