| Title | Assessment of energy security using social network analysis and food web analysis |
| Summary | This thesis explores the applicability of network analysis, especially food web analysis metrics to assessing energy security. It identifies two “system” indicators (Average Mutual Information and Conditional Uncertainty) and two “local” indicators (Trophic Level and Omnivory Index). The system indicators reflect vulnerability and resilience of national energy systems and are relatively easy to calculate and interpret. The system indicators do not correlate with the level of economic development but do depend upon the geographic location of the country. They also correlate with the widely used measure of energy security: the diversity of energy sources. At the same time they provide more information into potential vulnerabilities of energy systems than merely aggregate diversity. The local indicators potentially reflect the quality of energy consumed at each energy level and the variance in the energy consumption. In this thesis they are applied to primary energy systems, electricity and three end-use sectors at the national level as well as to international gas and oil trade networks. These two indicators are not independent of each other and do not correlate with existing indicators, thus making interpretation more challenging. They more accurately reflect the role division in case of gas trade network than in case of oil trade network. Further work is required to make these indicators policy relevant. |
