Peer-to-peer solar and social rewards: evidence from a field experiment

Working paper by Stefano Carattini, Kenneth Gillingham, Xiangyu Meng, Erez Yoeli on 9 Nov 2022

Peer-to-peer solar offers households who cannot have solar panels fixed to their own homes to access solar energy from their neighbours. But because this is an invisible form of pro-environmental behaviour, the rewards in the form of social approval are lower. This working paper finds that the ability to share reports of green behaviour online made people more likely to show interest in the scheme.
