Abstract

This paper discusses the effect of residential energy prosuming on households’ energy consumption behavior with the objective to find evidence for a “prosumer rebound effect” on energy consumption. Prosuming is the partial self-consumption of distributed energy production. We hypothesize that prosumer households are systematically different from consumer households regarding their housing situation and socio-economic characteristics. We address sample selection bias by using a quasi-experimental technique called propensity score matching as our identification strategy. We employ data from a nationwide online survey among homeowners in Germany. While the data shows a correlation of lower energy consumption and prosumer households, we find no significant difference of energy consumption behavior between prosumers and non-prosumers when controlling for sample selection bias. Instead, the lower energy consumption of prosumer households is attributed to more energy-efficient technical equipment and thus to purchasing behavior. Our results show neither evidence for negative nor positive externalities of prosuming on residential energy consumption behavior and therefore we conclude that there is no need for additional governmental measures in the form of taxation or subsidies to address behavioral changes of energy prosuming.
