This chapter reviews the research literature that has aimed to formulate and estimate energy security quantitatively. Energy security is defined as an entity containing dimensions and components represented by metrics. Adopting a geopolitical perspective that is lacking, selected quantitative approaches used for the computation of energy security indexes are reviewed. Research into the role of energy markets is reviewed. Many simple (disaggregate) indicators, composite (aggregate) indicators, and complex indexes of energy security are mentioned. Complementary qualitative techniques such as interviews are discussed. Reviewed works were found to analyze energy security metrics using: numerical (scoring/ranking, weighting, organizing into a matrix); statistical (z-score approaches, correlation analysis, consumer surveys); multivariate statistical (multiple regression, Principal Component Analysis, Factor Analysis, Cluster Analysis on static of time-series data); econometric (time series approaches); multi-criteria decision making (Analytic Hierarchy Process, Fuzzy Analytical Hierarchical Process, Preference Ranking Organization Method for Enrichment Evaluations); (accident) risk assessment; complexity (time series analysis coupled with path dependency and lock-in concepts, Agent-Based Models); risk assessment (covering energy, social, institutional and political factors); game theoretic; and qualitative (e.g., interviews, expert panels) methods and techniques. Public perceptions were occasionally taken into consideration. Regarding the scope of the reviewed research, several works examine case studies of a single or a few countries; others analyze more countries, usually located in a region (such as Europe or Asia); some studies concentrate on regions or provinces. The chapter is concluded with a roundup of main points. |
