We report on a three-week field study in which participants from nine households were asked to annotate their domestic electricity consumption data using a prototype interactive visualisation. Through an analysis of the annotations and semi-structured interviews, our findings suggest that the intervention helped participants to develop a detailed and accurate understanding of their electricity consumption data. Our results suggest that energy data visualisations can be improved by having users actively manipulate and annotate their data, as doing so encourages reflection on how energy is being used, facilitating insights on how consumption can be reduced. One of the key findings from our thematic analysis was that participants went beyond the data in their reflections, talking about generational issues, upbringing, financial matters, socio-economic comparisons, environmental concern, mistrust towards utilities, convenience, comfort and self-reported waste. Reading beyond the data illustrates the importance of social practices in the context of energy feedback, embedding eco-feedback research into the relevant context of sociology and psychology research.
