Highlights • Randomized field trial focusing on nudging and residential electricity consumption. • Examined nudges include energy saving tips and peer comparisons. • Interest in monitoring electricity consumption is linked with nudge efficacy. • Email delivered energy saving tips reduce electricity consumption in wintertime.

This article evaluates the impacts of information nudges on residential electricity consumption with a randomized field experiment. This opt-in experiment was conducted in Finland. Information was administered via monthly email newsletters and an online energy service platform. The aim is to find out whether i) energy saving tips combined with and without online energy service platform providing electricity consumption information, and ii) peer comparisons (i.e., social norm) influence households’ electricity consumption. The results show a high seasonal variation in the treatment effects within the groups who were registered users of the online energy service platform. Those with access to usage feedback and versatile energy savings tips (without the social norm comparisons) reduced their electricity consumption around 10% in wintertime. The results imply challenges in encouraging energy saving behavior among households less interested in following their electricity consumption.
