Setting up a contest is a popular means to promote pro-environmental behaviors. Yet, research on contest-based interventions is scarce while norm-based interventions have gained much attention. In two field experiments, we randomly assigned 79 apartments to either a contest-based or a norm-based electricity conservation intervention and measured kWh usage for 2 and 4 weeks, respectively. Results from both studies showed that contest-based interventions promote intensive but short-lived electricity saving. In Study 1 apartments assigned to a norm-based intervention showed more stable electricity saving (low intensity and long-lasting). Study 2 did not replicate this finding, but supported that participants in the norm-based intervention also engaged in non-targeted behaviors. These results emphasize the importance of identifying how different intervention techniques may activate different goals, framing both how people think about and act upon targeted pro-environmental behaviors.
