Motivating energy conservation in the workplace: An evaluation of the use of group-level feedback and peer education

Research suggests that curbing consumer demand for energy through behavioral interventions is an essential component of efforts to reduce greenhouse gas emissions, particularly in the short-term. Behavior within organizational settings poses a particular challenge to those wishing to promote energy conservation because employees typically have no direct financial incentive to reduce energy use and rarely have access to information regarding their level of consumption. Two relatively simple and easy-to-implement interventions were evaluated in a workplace setting during the fall of 2008. The first involved group-level feedback presented monthly to employees via e-mail. The second used peer educators to disseminate information and to encourage colleagues to reduce energy use. Both interventions were compared to an information-only control designed to educate employees about how and why to conserve energy. Results indicated that feedback and peer education resulted in a 7% and 4% reduction in energy use, respectively. Buildings that received the control increased energy use by 4%. The effect of peer education was limited by implementation failures in two buildings. The utility of these interventions will be discussed in terms of their overall potential for reducing energy use, as well as the feasibility of their being implemented in future organizational settings.
