An international assessment of energy security performance

Energy security has in recent years grown as a salient policy and political issue. To better understand energy security and sustainability concerns, this study's main objective is to present an energy security index which measures national performance on energy security over time. Based on three years of research involving interviews, surveys, and an international workshop, this study conceptualizes energy security as consisting of the interconnected factors of availability, affordability, efficiency, sustainability, and governance. It then matches these factors with 20 metrics comprising an energy security index, measuring international performance across 18 countries from 1990 to 2010. It offers three case studies of Japan (top performer), Laos (middle performer), and Myanmar (w]orst performer) to provide context to the index's results. It then presents four conclusions. First, a majority of countries analyzed have regressed in terms of their energy security. Second, despite the near total deterioration of energy security, a great disparity exists between countries, with some clear leaders such as Japan. Third, tradeoffs exist within different components of energy security. Fourth, creating energy security is as much a matter of domestic policy from within as it is from foreign policy without.

► Energy security consists of availability, affordability, efficiency, sustainability, and governance. ► These concepts can be matched with 20 metrics comprising an energy security index. ► Using this index, this study measures international performance across 18 countries from 1990 to 2010.
