What can feminist epistemology and methodology offer the study of regional issues? To answer this question, this chapter draws on a domestic energy project with older low-income households in the Illawarra, a region of New South Wales, Australia. The energy field is characterised by an unusual degree of transdisciplinary research. It is therefore helpful to consider what methodologies may facilitate such research. Attentive to the feminist concepts of ‘situated knowledge’ and ‘positionality’, this chapter outlines three components of thinking a methodology through feminism: (1) beyond the science/social science divide; (2) everyday knowledge of domestic energy efficiency; and (3) experimental narrative approaches to investigating energy efficiency. The chapter opens up important dimensions that might help recognise and mitigate against the imbalances of power in relationships doing transdisciplinary research.
