The 2009 Aspen Forum on Global Energy, Economy and Security explored “Oil and Gas in a Changing World,” reflecting the turmoil in the industry caused by the severe economic recession and highly volatile oil and gas prices. Topics included the dramatic increase in U.S. gas reserves as a result of production of gas from shale, the potential for improved efficiency to reduce demand for oil, and the prospects for various alternative fuels and automotive technologies. The Forum co-chairs were Luis Giusti, Senior Advisor to CSIS and former CEO of PDVSA, and Joseph A. Stanislaw, independent senior advisor to Deloitte LLP and CEO of The JAStanislaw Group.
