“Impact” is a series of design proposals that help consumers improve their residential energy efficiency by exposing and helping manage consumption in encouraging ways. Our concepts leverage Smart Grid capabilities like electricity price information and smart appliances along with knowledge of design for effective behavioral change. Our solutions would raise awareness, inform decisions as they're made, provide motivation for change, and even provide new capability without adding extra effort or inconvenience. While others have focused on the motivated minority, we have emphasized convenience and usefulness.
