The latest issue of Nature Energy is out. There is an interesting paper that puts together a miscellaneous of concepts from different theories in political philosophy to build an "energy justice framework centred on availability, affordability, due process, transparency and accountability, sustainability, equity and responsibility".
The authors recognize eventual conflicts between these different ideas but I think they don't make it very clear how the ethical framework they propose actually overcomes such conflicts. In any case, it's a good read.
Thanks Tim Schwanen for the tip.
