A B S T R A C T . This article offers a fresh perspective on the evolution of energy consumption in Britain from the s to the s. The twentieth century witnessed a series of energy transitions -from wood and coal to gas, electricity, and oil -that have transformed modern lives. The literature has primarily followed supply, networks, and technologies. We need to know more about people and their homes in this story, because it was here where energy was used. The article investigates the forces that shaped domestic demand by focusing on working-class households in public housing. It examines the interaction between political frameworks, public housing infrastructures, and the changing norms and practices of people's daily lives. It connects social and political history with material culture and compares the different paths taken in London, Stocksbridge, and Stevenage in the provision of gas, electricity, and heating. Evidence collected by local authorities is used to analyse the uptake, use, and resistance to changes in domestic infrastructures, such as gas-lit coke ovens and central heating. The case-studies make a more general pitch for a new historical study of energy that places people's lifestyles, their ideas of comfort, and political attempts to change them more squarely at the centre of inquiry. On March , Mr Luford wrote to the chairman of his local council in Stocksbridge, a small industrial town at the outskirts of Sheffield in south Yorkshire. He had learnt that a power cable for the Spink Hall estate would pass his council house and asked for permission to have it wired. He also wanted to know whether a tenant who wired his home but later moved out would be compensated for his investment. A week later, the council met and resolved that tenants had permission to wire their houses as long as they pledged not to remove gas pipes and restored all gas fittings if they left. Mr Luford's questions were testing the meaning of tenants' 'freedom of choice' between gas and electricity, which had been the subject of national debate a few years earlier. Mr Luford's home was one small piece in the bigger story of twentieth-century energy transitions. For Britain, the picture is clear at an aggregate level. The decline in the use of coal for domestic cooking and heating of space and water started in the interwar years and accelerated in the s and s, while the consumption of gas (first town gas then natural gas) and electricity rose. We know surprisingly little, however, about the micro-changes in demand that made up this macro-development. Electric lighting was promoted as cleaner and safer than gas, and electric fires as admittedly more expensive but flexible sources of quick, smokeless heat. Gas providers, by contrast, disputed that the future would be electric, insisting that people preferred gas for cooking. Coal interests argued for the continued use of solid fuels, especially for heating. But what did end-users think and how did they actually use these fuels? The aim of this article is...
