In this chapter I examine a sociotechnical system deemed central to achieving global sustainability, renewable energy. Through a focus on Canadian policy, I explore carbon reduction through fuel substitution and electrification, common pathways being promoted to advance an energy transition. By combining a transformative climate justice framework with an examination of embodied energy injustices, I centre an interrogation of power and injustice to examine the existing and magnified impacts of low-carbon pathways, particularly on peoples and communities that are marginalized. I argue that the problems of injustice encountered across the energy transition are endemic to achieving sustainability overall, and that we need to ground our ambitious commitments to address climate change and global sustainability in considerations of justice and injustice if we are to make headway on addressing these crises.
