To achieve the international emission reduction targets, current researches underline the need to overcome the dominant techno-centric approaches to energy transition, in favor of analyses that explore in more detail those practices and organizational assets that play a role in favoring a transition towards a low-carbon society. In this light, the article focuses on governance practices and, in particular, on the different tools and actors involved across variable scales and temporalities. Drawing on the activities of the ERASMUS+ Strategic Partnership for Higher Education LOTUS (Locally Organized Transition of Urban Sustainable Spaces), a selection of European case studies is explored and compared in light of (i) the implemented actions in terms of energy production and efficiency measures, (ii) the legal framework and the origin of the funding and (iii) the number and type of involved actors and their partnerships. On this basis, the analysis outlines, from both a theoretical and a practical stand, a number of critical issues that characterize these episodes of energy transition governance. In particular, the authors reflect upon the interaction between energy measures and urban contexts, the need for synergies among government level and the emergence of new forms of partnership among public, private and third parties’ actors.
