Energy Systems Analysis Group

Energy Systems Analysis Group

A public symposium, “Energy for a Carbon-Constrained World,” was held April 3, 2017 in honor of Robert H. Williams, long-time head of the Energy Systems Analysis Group, on the occasion of his retirement from Princeton University. A collection of testimonials and well wishes for Robert Williams is available here. Additional contributions to this collection are welcome. Please send yours by May 1, 2017 to Eric Larson (

The Energy Systems Analysis Group (ESAG), a research unit at Princeton University since 1971 and part of the Princeton Environmental Institute since 2001, moved to the Andlinger Center for Energy and the Environment in July 2015.

Research activities focus on identifying technologies and technology strategies and policies that could facilitate solutions for the long term of major energy-related societal problems—including global climate change, urban air pollution, energy-import dependence, the risk of nuclear weapons proliferation, and poverty in developing countries.

Members of ESAG advise dissertation research of graduate students in diverse departments at Princeton, including those in the School of Engineering and Applied Science and the School of Public and International Affairs. ESAG welcomes participation in its research and training by interested faculty and students.
