This Handbook examines the subject of energy security: its definition, dimensions, ways to measure and index it, and the complicating factors that are often overlooked.

The volume identifies varying definitions and dimensions of energy security, including those that prioritize security of supply and affordability alongside those that emphasize availability, energy efficiency, trade, environmental quality, and social and political stewardship.　 It also explores the various metrics that can be used to give energy security more coherence, and also to enable it to be measured, including recent attempts to measure energy security progress at the national level, with a special emphasis placed on countries within the Organization of Economic Cooperation and Development (OECD), countries within Asia, and industrialized countries worldwide.　

This Handbook:

• Broadens existing discussions of energy security that center on access to fuels, including "oil security" and "coal security."　

• Focuses not only on the supply side of energy but also the demand, taking a hard look at energy services and politics along with technologies and infrastructure;

• Investigates energy security issues such as energy poverty, equity and access, and development;

• Analyzes ways to index and measure energy security progress at the national and international level.

This book will be of much interest to students of energy security, energy policy, economics, environmental studies, and IR/Security Studies in general.
