This document describes a research project that examines how individual and shared meanings around energy and sustainability change over time. The project conducts longitudinal interviews with residents of eco-communities in Wales, including Lammas and Tir-y-Gafel, to understand how their practices and perspectives may transform. It finds tensions between shared goals of sustainability and more personal connections to place. Specifically, striving for self-sufficiency creates dilemmas and potential "waste" when economic dependencies remain. The project aims to capture these "quiet struggles" as local meanings interact with and potentially reshape wider sustainability meanings.
