Abstract
This paper reconstructs the trajectory of energy efficiency policies in Berlin from the 1920s to today in order to illustrate how the shifting political and socioeconomic conditions of a city can shape urban energy provision and consumption. Taking a long-term perspective on the relationship between urban transitions and energy policy, it investigates how the geo-political turbulence, regime diversity and socioeconomic volatility experienced by 20th-century Berlin influenced strategies of electricity generation and use in the city. Drawing on different ways of conceptualising change to socio-technical systems in the literature, the paper’s findings present a more differentiated picture of urban energy transitions than notions of path dependency and transition pathways imply, highlighting the importance of non-linear trends, political contestation and crisis discourses in and beyond the city and their relevance for reconfiguring urban energy systems today.
