This paper explores social representations of wind energy development within reindeer herding lands among the Indigenous Southern Saami living within Norwegian borders. For this matter, the paper combines Social Representations Theory (SRT) with the analytical framework of "circuits of dispossession and privilege" and decolonial approaches within community psychology. Data consisted of seven individual semi-structured openended interviews, three collective interviews, and observation in three lawsuits, public meetings, protest actions, and reindeer herding activities. The findings suggest that for the subjects in this study, the onset of wind power represents the renewal of historical processes of dispossession through accumulation and colonialism, enabled by harmful knowledge gaps in Norwegian society and institutions, contrasting Southern Saami's values of responsibility and ecological practices. The implication of these findings suggests an urgent need of rethinking renewable energy and including indigenous knowledge in climate change agendas.
