Governing a just energy transition requires detecting and anticipating energy injustices. Although much scholarly attention has been given to frameworks to analyse energy injustices, a consistent framework for policymakers and researchers to detect them is lacking. Current methods for detecting what the publics perceive as (un)just rely on explicit articulations of grievances by citizens in official participatory settings or during energy conflicts. However, it is implausible that all injustices manifest within these contexts. This study introduces a framework to understand why injustices might remain unseen and unaddressed, inspired by the concept of hidden morality as introduced by the philosopher Axel Honneth. The framework of hidden morality conceptualises several steps between an injustice and social change: (1) experience of injustices; (2) expression of injustices; (3) collective action; (4) uptake in public discourse; (5) reformulation; and (6) social change. Between each of these steps, different obstacles can arise. The paper explores the mechanisms that prevent energy injustices from surfacing and being resolved through philosophical literature and two case studies. Its contribution is twofold: it raises awareness of the fact that injustices can remain undetected, and it proposes a framework that is the first systematic tool for policymakers to detect injustices when making energy policies.
