In the scientific literature on energy transition toward decarbonization, the learning process is often described as a preferred way to achieve change. However, despite a large number of theoretical and empirical endeavors, a systematic understanding of the process is still lacking due to the diversity of disciplines and approaches and to the multi-layered nature of the phenomenon. The aim of this systematic review is to highlight the dimensions of learning processes from a cultural psychological point of view in order to understand and assess different planes of the relation between humans and technology. We thus explore the literature following the PRISMA protocol. Through a narrative synthesis, we critically assess the theoretical and methodological advancement, the presence of cultural determinants, the value ascribed to agency, and the depoliticization risk. We found that: theories and methodologies still lack systematicity and concordance in their application; learning processes are studied with little focus on the context and are mostly treated as facilitators; agency mostly lacks a psychosocial focus, despite the exploration of multi-level problems; and the depoliticization of learning is a matter of fact. Nevertheless, positive examples are present, although they are few. Epistemological and political implications are discussed, and a psychosocial conception of agency is proposed, together with a reflective stance for researchers.
