摘要：The last years have brought on Eurasia’s geopolitical scene a new concept of “hard energy”. It does not represent a new form of energy, but a new way to conduct foreign policy: natural gas against political concessions. On the one hand there is Russia, almost the sole supplier of natural gas, that has managed a spectacular transformation from a military superpower that threatened with tanks, in an energy superpower that threatens with closing the “tap”, and on the other hand there is Europe which is in the delicate situation of being dependent on Russian gas. This study aims to accomplish an introspective, exploratory and interpretative analysis of the way natural gas has become a first-hand geopolitical factor in shaping the architecture of the geopolitical relations in Eurasia, relations determined by the gas and pipeline wars. From geoeconomy, back to geopolitics.
