Query: Socially Intelligent Interfaces for Increased Energy Awareness in the
  Home   This paper describes how home appliances might be enhanced to improve user
awareness of energy usage. Households wish to lead comfortable and manageable
lives. Balancing this reasonable desire with the environmental and political
goal of reducing electricity usage is a challenge that we claim is best met
through the design of interfaces that allows users better control of their
usage and unobtrusively informs them of the actions of their peers. A set of
design principles along these lines is formulated in this paper. We have built
a fully functional prototype home appliance with a socially aware interface to
signal the aggregate usage of the users peer group according to these
principles, and present the prototype in the paper.
