Aspen Policy Books is a series devoted to developing critical new thinking on U.S. national security policy. This book is a collection of papers prepared for the 2007 summer Aspen Strategy Group conference on The Global Politics of Energy. This cross-disciplinary and high-level examination of policy strategies for addressing the challenges posed by the soaring demand for oil, the rise of petro-powes, and the implications of climate change makes energy security issues urgently relevant to the American and global policy communities.
