Approaches to a new regional energy security model in the perspective of the European transition to green energy

The EU energy sector became a very important one as a result of the war in Ukraine. On the other hand, the EU started in defining and implementing new strategies regarding green economy and sustainability. Even though these strategies cover short and medium periods, they have as a main goal the decrease in the EU's dependence of energy imports. This research is focused on present challenges, risks, and uncertainties related to energy production and consumption in all EU member states. In order to achieve the research objectives, a huge statistical database, which covered 2012-2021, was used. The analysis is based on specific indicators regarding primary energy production; imports and exports; gross available energy; final energy consumption; non-energy consumption; energy dependency; and energy intensity. There are at least three research procedures used in this paper: a meta-analysis, a statistical analysis, and an econometric analysis, as well. Finally, the analysis points out the disparities between member states regarding energetic resources and energy dependency using a new model for quantifying risk factors in the European energy system. Moreover, new public policies are proposed by the authors under a cluster approach of the EU's regions.
