​As energy is becoming one of the crucial concerns in the EU, this volume provides an in-depth analysis and interdisciplinary perspective on European energy security. Given the multidimensional nature of energy security in terms of physical availability, affordability and geopolitical security, it brings together authors from different backgrounds pursuing a distinctly multidisciplinary approach. The authors'' different perspectives correspond to the three sections of the book: international relations, which focuses on Eastern EU partners; energy economics, which highlights the current unconventional hydrocarbons revolution and its impact on EU energy and climate strategies; and public policy, which analyzes EU policies in the context.
