U.S. Chamber of Commerce Institute for 21st Century Energy looks mighty interesting. The term "energy security" as an American priority appeared to be largely absent from peak US Administration statements for seveal years from 2002 but other than that see the discussion of US and international energy security at http://www.energyxxi.org/energy-security-risk-index :
"Since the early 1970s, Democratic and Republican presidential administrations and other policymakers have made energy security a priority. Yet, we have lacked a tool to regularly measure our nation's progress and thus assess the impact of policy decisions on America's energy security. Indeed, energy is still recognized today as among the top challenges to our Nation's future prosperity, national security, and way of life.
In 2012, the Energy Institute launched the International Index of Energy Security Risk, a new tool designed to facilitate a better understanding of global energy markets. The International Index applies the same quantitative analysis used in the US Index to rank the top global energy users in 28 metrics."
