The deployment of new energy technologies has been a driving force behind the global energy transition in recent decades. This progress reflects a broader alignment of national innovation systems with low-emission energy goals and environmental commitments. However, conventional energy innovation systems have deepened social inequalities at both national and international levels and failed to enable marginalised groups to develop solutions tailored to their specific energy needs. As a result, these groups are often forced to adopt technologies designed for affluent, grid-connected users—solutions that are not fit for purpose to address barriers related to gender, geography, poverty, education, and disability. To ensure inclusion becomes both an outcome and a defining feature of the innovation process, energy innovation systems must undergo fundamental reconfiguration. This paper proposes innovation system interventions that can deliver a just energy transition through a transformation of system actors, their modes of interaction, and the knowledge infrastructure that supports the system.
