We propose to work with academic partners and commercial and NGO stakeholders to (a) design compelling representations of electricity meter data, and (b) prototype innovative ways to use the Internet to present these representations to encourage more people to reduce their energy consumption. The work will be informed by prior academic research, current state-of-the-art and three workshops. The project will culminate in a conference designed to enhance knowledge and skills in using ICT to support behaviour change initiatives. All project outputs will be actively disseminated with open licences and made available online in perpetuity.
