Rapid energy transition is one of the battle-cry for fighting climate change emergencies. Renewables are pushed and promoted by state and non-state actors to achieve decarbonisation and energy security. Scholars have critiqued the large, utility-scale renewable energy projects being pushed in the rural frontiers from an energy justice (distributive, procedural, and recognization-based) perspective. Against this backdrop, small-scale renewable projects are promoted as a viable alternative to utility-scale projects. Several well-intentioned developmental and environmental advocacy groups are uncritically advocating small renewable projects. This talk, using a case study method, critiques the uncritical advocacy of small renewable energy projects in the rural global south as a pathway for energy transition. We enquire whether small- and medium-scale low-carbon-based energy projects are always just (socially and environmentally) by studying a small solar park in Nawada, Bihar. The talk politicises the energy transition debate by bringing the voices of marginalised agrarian farmers (small farmers, sharecroppers, agrarian workers) from rural India. We argue that the environmentalization of the energy debate is helping the dominant actors push the market-based, neo-liberal energy transition models as “standard business models” at different scales for promoting energy transition. This trend is part of green colonialism, which is creating deprivation, dispossession and discontent among the rural masses, who are surviving on subsistence agriculture in many parts of India. The uncritical framing of the “small scale” and “environmental” solutions for fighting climate emergency through small renewable-based grids needs to be questioned. Until “small-scale”, “environmental solutions” engage with the question of social justice (largely local, regional and national debate) and energy and environmental justice (the more national and global debate), it will end up perpetuating inequities and injustices (procedural, distributional and recognization based) among the most marginalised and vulnerable populations in the global south.
