The document summarizes key aspects of the Energy Biographies research project. The project uses longitudinal biographical interviews and participant photography to explore how people make sense of their energy use and envision sustainable energy futures. Interview discussions focus on topics like daily routines, life transitions, and views of past and present visions of technology and society. The project aims to understand how people's lived experiences and social practices shape their temporal horizons and ideas about sustainable futures. Preliminary findings suggest the interviews increase awareness of energy use and that discussions of retro-future visions critique unchecked technological optimism, while discussions of alternative futures emphasize self-sufficiency and disconnect from trajectories of endless growth.
