Sharon Klein’s research is interdisciplinary in nature and centers on the technical, economic, environmental and social trade-offs inherent in the production, distribution, and use of energy. Dr. Klein uses engineering-economic analysis, environmental life cycle assessment, social benefit-cost analysis, and multi- criteria decision analysis to assess trade-offs in energy decision-making. She is interested in all energy options that have the potential to lead to a more sustainable energy future. Her current and near-term research interests center around grassroots community renewable energy and energy efficiency. Professor Klein is a Margaret Chase Smith Policy Center Faculty Fellow for 2016-17.
