Our Keynote Speakers

Anna Alberini

Anna Alberini received her PhD in Economics from the University of California San Diego. She is currently a professor in the Department of Agricultural and Resources Economics at the University of Maryland, College Park. She teaches PhD-level econometrics courses, undergraduate statistics courses based on energy and environmental data, a course in the economics of climate change, and supervises numerous graduate and undergraduate research projects. She is an energy and environmental economist with a major focus on the economics of health and safety and non-market valuation. Her energy economics research focuses on residential energy demand, energy efficiency decisions and consequences of such decisions, policies targeted as shaping residential energy demand, and on vehicle fuel economy and driving decisions. Her work has appeared in the Energy Journal, Energy Economics, Energy Efficiency, JEEM, the Review of Economics and Statistics, the Journal of Health Economics, and other journals. Alberini has served two stints on the Science Advisory Board for Environmental Economics to the US Environmental Protection Agency and is currently the chair of the American Statistical Association committee that advises the US Energy Information Administration. She is also a member of the Editorial Board of The Energy Journal, of the International Advisory Board of Energy Policy, and an associate editor of Energy Efficiency.

His work on energy, applied econometrics, and technological change has been published in leading international journals (including Climatic Change, Energy, Technological Forecasting and Social Change, Energy Policy and Health Economics).



Gunnar Luderer

Gunnar Luderer leads the Energy Systems Group at the Potsdam Institute for Climate Impact Research and is the Lead Scientist for the REMIND Integrated Energy Economy Climate Model as well as Deputy Chair of Research Domain 3 - Transformation Pathways and Professor of Global Energy Systems Analysis at the Technische Universität Berlin. His research explores sustainable energy transformation pathways towards climate neutrality on the global, regional and national level. He was a lead author of the 2013 and 2018 UNEP Emissions Gap Reports and a contributing author to the Fifth Assessment Report, the Special Report on Renewable Energy Sources as well as the Special Report on Warming of 1.5°C of the Intergovernmental Panel on Climate Change. Gunnar Luderer has published more than 100 papers in peer-reviewed scientific journals, and was recognized as one of the World's most Highly Cited Researchers by the Web of Science Group in 2019 and 2020.



Trieu Mai

Senior Energy Researcher, National Renewable Energy Laboratory


Trieu Mai is a Distinguished Member of the Research Staff at the National Renewable Energy Laboratory (NREL) and has led and conducted research in a broad range of energy topics, including renewable grid integration, clean energy policy, technology innovation, and electrification. His research utilizes an array of power system models and energy-economic analysis tools with the primary aim to evaluate the pathways to reaching high renewable electricity systems as well as the challenges and impacts of doing so. Since joining NREL in 2009 Trieu has co-authored over 80 papers and served as the principal investigator on several visionary Department of Energy and NREL studies. Trieu holds a Ph.D. in physics from the University of California Santa Cruz.
