This document summarizes a presentation given by Prof Karen Henwood on insights from studying energy biographies and everyday energy use. It discusses the Energy Biographies project which used qualitative longitudinal interviews and visual methods to understand dynamics of everyday energy use. Key findings included enhancing reflections on practices and meaning through participant photos and videos. The project prompted reflections on usually intangible energy use and emotional attachments to practices and infrastructure that influence potential for change. While lifecycle transitions are seen as opportunities for intervention, thicker analysis of disruption is needed to understand how identities are negotiated through such changes.
