The rollout of smart electricity meters is gathering pace in the EU as in the US. In this video, ANDREAS GERSTER asks what information smart meters should provide to bring about an optimal reduction in energy consumption. Comparing the effectiveness of aggregate data and appliance specific feedback, Gerster shows that more detailed information can help households to significantly limit their electricity use. Highlighting potential savings for German households of some €500-600M per annum, the research also develops a novel method of cost benefit analysis that can be used in settings where consumer misperceptions are an issue.


Andreas Gerster is the Acting Chair of Quantitative Economics at the University of Mannheim. Having completed his doctoral research at the Ruhr Graduate School of Economics, Gerster previously worked as a researcher at the RWI - Leibniz Institute for Economic Research. Gerster’s main research interests include environmental economics and public economics. He was joint recipient of the 2020 IIPF Young Economist Award.
