In 2009, ESAI Energy took over from Energy Security Analysis, Inc, the analysis of geopolitical factors that shape energy markets and influence energy security decisions. Specifically, ESAI Energy’s analytical team represents a wide range of geographic expertise and provides monthly analyses of Russia, the Caspian countries, China and the countries of Latin America and Europe. ESAI Energy collaborates with faculty members at the US Naval War College to produce the biweekly Intelligence Briefing, which covers a wide range of geopolitical issues in the Arab Gulf. In 2014, Sarah Emerson of ESAI Energy and Andrew Winner of the Naval War College published The Myth of Petroleum Independence and Foreign Policy Isolation in the Washington Quarterly.
The work of ESAI Energy builds on the legacy of Energy Security Analysis (ESAI). In 1987, ESAI published SPRO-Watch, a Guide to Strategic Stock Drawdowns in the Persian Gulf Crisis of 1987. In early 1991, ESAI published The Crude Oil Market after the Iraq Crisis, which provided a detailed analysis of the longer term implications of the Gulf War. From 1990-1995, ESAI published a quarterly journal entitled Petroleum Politics, which analyzed any kind of political development which affected petroleum. ESAI remained engaged in the energy security debate, publishing Energy Security Revisited: New Approaches for a Global Petroleum Market in 1999. Since then ESAI has conducted proprietary studies on energy security policy for the U.S., Japanese and Indian governments. In 2003, ESAI published After Saddam: Stability in the Persian Gulf, and in 2006, ESAI President, Sarah Emerson, published When Should We Use Strategic Stocks? In the journal, Energy Policy.
