Energy and the Environment

Our Vision

Energy presents one of the biggest challenges we face as we seek more sustainable ways to provide society with goods and services. Energy is an essential input to nearly every human activity, but extraction and utilization of energy resources have profound effects on the environment. Society's desire to access energy resources, which are distributed unevenly, raises geopolitical issues and energy security concerns. Addressing these challenges and understanding the ramifications of various energy alternatives requires both a systemic and multidisciplinary perspective, which can be obtained through the MEM Specialization in Energy and the Environment.

Kenneth Gillingham

Kenneth Gillingham

Professor Gillingham is an associate professor of economics at Yale University, with a primary appointment at the School of the Environment and secondary appointments in the Department of Economics and School of Management. He is also a faculty research fellow at the National Bureau of Economic Research. In 2015-2016, he served as the Senior Economist for Energy and the Environment at the White House Council of Economic Advisers. His research focuses on energy markets and uses a variety of approaches ranging from structural econometric modeling to field experiments to energy-economic system modeling and economic theory. Topics of interest include energy efficiency, new energy technologies, and sustainable transportation. Recent publications have focused on the adoption of solar photovoltaic technology, market failures in household energy efficiency, and the rebound effect in transportation. On-going research includes field experiments on solar and energy efficiency adoption and econometric models of the effects of policies to reduce greenhouse gas emissions from transportation. Other research covers the modeling of energy innovation and technological change, both at the micro-level and in the large-scale energy-climate models used to examine the effects of climate change mitigation policies. His work has been published in top-tier journals such as Science, Nature, PNAS, Marketing Science, Quantitative Economics, Journal of the Association of Environmental & Resource Economists, Journal of Environmental Economics & Management, and the Review of Environmental Economics & Policy.

Prior to joining the Yale faculty, he worked at the California Air Resources Board, White House Council of Economic Advisers, Stanford Energy Modeling Forum, Resources for the Future, and Joint Global Change Research Institute of Pacific Northwest National Laboratory.  He also the recipient of a Fulbright Fellowship to New Zealand.  His Ph.D. is from Stanford University, where he studied management science & engineering and economics. Before beginning a career as an economist, he was a wilderness ranger in Wyoming and New Hampshire. See full profile →
