This project will improve understanding of the relationship between ‘energy using practices’ and ‘energy services’. Practice theory is used to understand habitual actions, but research is largely qualitative. Energy services are better understood by energy practitioners: they are quantifiable and more amenable to engineering analysis and economic models. However, the foundations in broader social science are weaker. This work will explore the links, investigate the quantification of specific energy practices (e.g. nutrition and laundry) and test whether these can lead to improved understanding of energy trends and policy impacts compared to a focus on energy using technologies. We will draw on research on practices in the DEMAND EUED Centre at University of Lancaster. Energy policy has traditionally focussed on incentives for the adoption of technology however in this project will focus on its role in influencing user actions with existing technology through a PhD studentship.
