This paper discusses possible technical, economical and geopolitical consequences of the new energy scenario. We analyze the net zero emissions global race with an emphasis on the role renewable energies will play in this phenomenon and COP26's recent decisions on climate and energy transition. Using semiquantitative analysis method, the technological driving forces for future energy scenarios have been extrapolated. The technological developments and future scenarios regarding renewable energies are discussed comparing two different driving forces. Furthermore, there will be the discussion of possible geopolitical consequences due to fossil fuels trade depletion during energetic transition. Possible related consequences for MENA countries are investigated. In the last part there will be legal background analysis for electricity demand and renewable sources shift combined with techno-economical examples. Finally, considering all the contents, we drive our conclusions.This review comes from a team group presented during "GEM 2021-Green Energy Management, Towards a sustainable energy transition".

The actual economic system, which should "manage fairly and sustainably limited resources" 1 , can't support this population increase because it's a 'take-make-dispose' economy which uses limited available resources without considering future generations, neither the planet.The main problem is that it's generally cheaper to buy the product that has a worse impact on its environment than the equivalent product that does less harm (see Chouinard Yvon et al, 2011, [4]). The reason is that costs to planet are negative externalities of difficult computation and since firms are not held accountable for their activities, these costs will not be translated into higher prices for customers. This situation changed only in the last decades when terms like sustainability, true cost accounting, and socially responsible investing (SRI), etc… started to be used.Today, people are more conscious of sustainability relevance, industries are studying greener solutions and Governments are creating laws and setting goals to improve green-footprints. Furthermore, in the last few years a new concept, that may help, was born: the "circular economy", where products can obtain a second life at the end of their first product-lifecycle. This paper reports on the advances and efforts in action across the EU with respect to the sustainability of our production and consumption systems. By considering recent evidence, it also draws on some critical aspects, which will require urgent intervention in the near future.In 2014, Florin Bonciu 2 described the large-scale implementation of the circular economy in the European Union and which benefits can be obtained by facing the ineluctable changes.Reinier de Man and Henning Friege 3 , in 2016 described the last policy created by the European Commission entitled "Circular Economy Closing the Loop" and proposed a sustainable resource management, backed up by multiple strategies, to face the practical problems that can be found in the policy implementation,
