Rather than focus on household or appliance level disaggregation of energy use in domestic settings, in our recent work we have begun to explore how energy use supports the services of everyday life. Our 'service based' quantification of energy use helps explain dramatic variations in direct energy impact for similar practices, e.g. 2 orders of magnitude between the lowest and highest consuming ways of achieving 'entertainment and IT'. In this talk we reveal the hidden impacts of IT devices due to their emergent uses and increased interconnectedness, and the challenges these pose for us in creating next generation hardware and software for a lower carbon future.
