Due to a spatial turn in the socio-Technical transition literature, the geography of energy transitions has recently been taken increasingly seriously, leading to burgeoning research output on regional energy transitions since early 2010. Amidst this wealth of publications, however, it can be difficult to keep track of its diverse and constantly evolving landscape. This editorial therefore aims at developing a framework that allows for bringing multiple approaches to regional energy transitions into conversation with each other and that helps to understand and explain the complexity of these interdependencies in ways that go beyond observing regional variety in energy transitions.
