Abstract
Faced with the convergence of economic, social, political and environmental crises, the importance of the public sector has been rediscovered on a global scale. The article offers a review of the evolution of political and academic debates on public ownership in general and public services provision in particular over the last decades, with emphasis on the energy sector. Taking as a temporal and analytical reference the research and advocacy work developed by the authors and other scholar-activists based at the Transnational Institute from 2006 to the present, the article summarizes the main issues currently in the spotlight and highlights gaps in knowledge and points of contention. It also suggests elements for future research and campaign agendas around public ownership in different regions of the world.
