StepGreen is an umbrella project that brings together faculty and research from several disciplines including behavioral science, environmental engineering, and computer science. Our ultimate goal is to understand and address the problems inherent in changing energy consumption behavior. An important goal of the project is to deploy widely, reach critical mass, and study these factors in the field. Our main website, stepgreen.org, is designed to encourage individuals to reduce their energy consumption by leveraging online social networks. Some of the other projects we are working on include an exploration of how to structure our messaging to support a diverse body of users, a polar bear tamagotchi, and sensors that can automate the reporting of popular actions.
