In recent years, debates about energy justice have become increasingly prominent. However, the question of what is at stake in claims about energy justice or injustice is a complex one. Signifying more than simply the fair distribution of quantities of energy, energy justice also implies issues of procedural justice (participation) and recognition (acknowledgement of diverse values constitutive of ways of life). It is argued that this requires an acknowledgement of the relational nature of ethical subjectivity. Data from the Energy Biographies project at Cardiff University is used to explore the connections between the relational texture of everyday life and the ethical significance of energy. In particular, the contribution of embodiment, attachment and narrative as capabilities to the everyday ethical evaluation of different ways of using energy is shown to be significant. Ethical investments in ideas of a good life are implicit in bodily comportment, emotional attachment, and biographical narratives, it is suggested. Using multimodal and biographical qualitative social science methods allows these implicit forms of evaluation to become more tangible, and the moral conflicts between some forms of energy-using practices to be exposed
