Most online energy conservation interfaces assume that information provision is sufficient to induce behavior change and energy use reductions. A gap between behavioral theory and field practice partly explains why interfaces have not achieved this goal. In this paper, we describe a research program on human centered interactive interface design that bridges this gap with consumer based investigation of two energy reduction interfaces: Kidogo and Powerbar. Kidogo allows users to donate savings from energy conservation to public goods. In the first study, which examines Kidogo components, we investigate how alternative beneficiaries help users to connect emotionally with saving energy. In our second study, comparing Kidogo and Powerbar interventions, we investigate the ability of affectively and cognitively framed interfaces to persuade individuals to perform conservation behaviors. The first study suggests that interfaces should use negative valence images to establish an emotional connection, and the second provides evidence that affectively framed interfaces promote willingness to perform conservation behaviors.
