High resource users often have the strongest response to behavioral interventions promoting conservation. Yet, litlle is known about how to motivate them. We implement a field experiment in Qatar, where residential customers have some of the highest energy use per capita in the world. Our dataset consists of 207,325 monthly electricity meter readings from a panel of 6,096 customers. We employ two normative treatments priming identity - a religious message quoting the Qur’an, and a national message reminding households that Qatar prioritizes energy conservation. The treatments reduce electricity use by 3.8% and both messages are equally effective. Using machine learning methods on supplemental survey data, we elucidate how agency, motivation, and responsibility activate conservation responses to our identity primes.
