An approach to model the European Interchange Energy Network as a Small World Net

European energy policy pursues the objective of a sustainable, competitive and reliable supply of energy. In 2007, the European Commission adopted an energy policy for Europe with several documents and included an action plan to meet the major energy challenges Europe has to face. A farsighted diversified yearly mix of energies was suggested to countries, aiming at increasing security of supply and efficiency, but a wide and systemic view of energy interchanges between states are still missing. In a previous work of the same authors, energy import/export interchanges between European States were used to develop a geographic overview at one glance. In this paper, the European Interchange Energy Network (EIEN) is approached from a modelling point of view, as a Small World Net, by supposing that connections between States are characterized by a probability depending on economic/political relations between countries.
