International targets for emissions reduction are encouraging increasingly more households to become energy producers. We present analysis of Mumsnet, a UK online discussion forum (19 million visits/month), to explore unsolicited accounts of these energy prosumers to understand their motivation and experience of installing and living with one type of microgeneration technology: solar thermal panels for hot water. In so doing, we challenge research and policy approaches that assume financial and environmental motivations as dominant in householder uptake of microgeneration technology. We draw attention to the wider reality within which energy prosumption practices are performed, how they coincide with other home improvements, and how they relate to expectations about modern lifestyles. To conclude, we discuss the implications of this for policy.
