By connecting two historiographies that, with a few exceptions, have generally ignored one another-gender history and the history of energy-this introductory article for the special issue "Home and Hearth: Gender and Energies within the Domestic Space, 19th-21st Centuries" highlights the fruitfulness of this encounter. The household is a locus for energy practices and choices, where the marketing strategies of energy suppliers, public policies, and family decisions meet, all of which bring gender relations into play. We propose different avenues of analysis that open up prospects for research, especially regarding issues connected to the energy transition.
