Energy Diversification and Security in the EU: Comparative Assessment in Different EU Regions

Abstract

Various methods and tools have been developed to quantify energy supply security; however, there is no ideal framework to measure energy security, as the concept is multifaceted and context dependent. Energy supply security has always been an extremely important issue for European Union (EU) countries due to high import dependency, and recent events linked to the COVID-19 pandemic and the Russian invasion of Ukraine have made it exceptionally important to reconsider this problem to identify the crucial issues and address contemporary policy needs. This study endeavours to systematise the primary energy security indicators in terms of policy relevance and develop an energy security assessment framework to examine energy import dependency and diversification for the EU in view of recent problems. This study introduces an energy import diversification and security index which enables measurement of a country’s energy security level for comparison with other countries and identifies primary areas for improvement. The proposed framework is then applied to a case study of selected EU countries to examine regional differences and identify potential improvements.
