I appreciate how van den Broek takes energy literacy as an object, rather than a mere domain of inquiry. The author uses a literature review to develop a typology of the concept. This a useful starting point, but could use a similar approach that is conducted empirically.
I also think that the concept of energy literacy would benefit by simply finding out what people know about their relationship to energy/energy culture/energy infrastructures, rather than what they know in respect to sustainability in particular. Perhaps the energy ecology concept could be a resource for broadening the concept of energy literacy, while keeping it constrained enough to be useful. For instance, would knowing that nearby fracking sites/natural gas wells are having detrimental impacts on public health count as energy literacy? Or how about knowing that a local neighborhood interprets the plethora of incoming EV charging stations as a form of displacement or of gentrification? I think so.
