The tenet-based approach to energy justice has seen substantial uptake over the past decade. Despite referring to philosophical terminology, energy justice scholars rarely engage rigorously with philosophical methods or ongoing debates. We argue this absence is challenging for two implicit goals that often arise in applications of the approach: to describe and capture ethical-issues surrounding energy systems and to normatively evaluate choices, actions, and events surrounding these issues in reference to justice. In this paper, we discuss these descriptive and normative challenges within the energy justice scholarship. We outline a series of measures, methodologies, and debates in philosophy that can aid in meeting these challenges. We argue that the energy justice scholarship can be strengthened by 1) explicitly justifying normative assumptions; 2) acknowledging the breadth and interpretability of tenets by distinguishing concepts and conceptions of justice; and 3) including insights from ongoing debates in moral and political philosophy, which offer conceptual tools and theories to better capture ethical energy related issues. Combined, these suggestions form a research agenda to help energy justice scholarship better articulate, rationalise, and meet its goals.@en
