Exploring the Spatial Dynamics of a Just Regional Energy Transition: What If We Ask Citizens?
Environmental Policy and Governance, EarlyView.ABSTRACT The installation of wind turbines and solar parks in valued rural landscapes has led to local concerns and perceived injustices to the extent that the societal acceptance of the energy transition is at stake. Although the literature on energy justice is blooming, research into citizens' understandings of justice with regards to regional energy
