Biography

Carmen Difiglio serves as Deputy Assistant Secretary for Policy Analysis in the Office of Policy and International Affairs, U.S. Department of Energy (DOE). He is responsible for DOE's analyses of energy policies. Highlights of his DOE career include the significant role he played in developing the Clean Air Act Amendments of 1990 and the Energy Policy Acts of 1992 and 2005. He also directed the U.S. Alternative Fuels Council and has supervised the development of a National Energy Strategy. His career achievements were recognized with a Presidential Rank Award (1997). Carmen Difiglio served 6 years (1998-2004) as Head of the Energy Technology Policy Division at the International Energy Agency (IEA). There he developed a new world energy model, supervised the development of several IEA publications and contributed to IEA's World Energy Outlook series. Urban transportation demand models were the focus of Carmen Difiglio's early work. Later he developed one of the earliest "bottom-up" engineering-economic models of the transport sector. These bottom-up models have since become commonplace in energy policy analysis. Before joining DOE, Carmen worked as an economist for the Delaware Valley Regional Planning Commission, the Transportation Studies Center of the University of Pennsylvania, and the Federal Reserve Bank of Chicago. He has chaired the Committee on Energy and Transportation (Transportation Research Board) and the IEA Energy Efficiency Working Party. Difiglio is the author of many papers on energy economics, travel forecasting, fuel economy policies and other topics. His doctorate is from the University of Pennsylvania.
