Everyday life practices are one of the focuses of interest for so-called ‘sustainable transitions’. Efforts in making daily life more ecological have ranged from awareness-raising and behaviour change strategies to socio-technical innovations, but have produced limited results so far. In a present characterised by a prolonged and multifaceted crisis it is imperative that, as social scientists, we interrogate the (un)sustainability of everyday practices from a more critical angle, linking them to reflections about capitalism's ecological destructiveness. One fruitful way of doing (...) so is to interrogate the dimension of subjectivity as a space where collective discourses, practices and desires are embodied in concrete experience and actions. Drawing on ethnographic material on everyday energy use, I suggest that contemporary ways of living certainly contribute to the overall reproduction of capitalism and yet, in the (dis)juncture of the crisis, more sustainable livelihoods can be experimented with and prefigured. Subjectivity is one crucial dimension in which this process unravels. (shrink)
