Information and communication technology (ICT) consumes energy, but is also an important means of conserving energy. Conventionally, it has done so by optimizing the performance of energy-using systems and processes in industry and commerce. In the near future, ICT will also play a critical role in supporting the necessary paradigm shifts within the energy sector towards more sustainable electricity generation. However, with the advent of "smart" technology from the field of ubiquitous computing, further ways of reducing growing levels of domestic energy consumption are now emerging. With this in mind, we discuss how getting consumers "into the loop" can achieve energy savings on top of the efficiency gains resulting from automated systems, and we describe a prototype application aimed at inducing behavioral change by providing direct feedback on household electricity consumption.
