[en] The answers to the world energy crisis should not be limited to the management of geopolitical factors (Iran, Nigeria, Venezuela etc.) and to the control of the offer (inciting OPEC countries to optimize their production). They involve also a change of the demand and of the consumers' behaviour. The comments caused by the recent rise of oil prices have shown that this idea, considered as marginal by policy-makers, has started to make its way. The analyses limited to macro-economical units (states, international organization), always forget that cities are the main places of energy consumption. Recent events, like the repetitive saturation of power grids at the origin of spectacular blackouts (Moscow, California, Switzerland, Italy), have led the local authorities to take into consideration part of the problem. They effectively have at their disposition some important leviers which allow them to act both on the offer and on the behaviours. It is evident that in domains like transports, urban renovation or waste treatment, the local authorities have to play a significant role by implementing policies that maximize the energy efficiency and minimize the costs at the same time. The debates which took place during this forum were based on the experiences and realizations presented by experts of several big cities, in particular of Moscow, Madrid and Nuremberg. Some remarkable examples were presented, in particular in the domain of energy auditing, mastery of energy consumptions and production of alternative resources. The usual topics were also approached: energy overview, main trends of the present day energy policy of Russia, new opportunities of new technologies, geo-energy evolutions, Russia-European Union dialogue.
