Energy On the Move: longitudinal perspectives on energy transitions among marginal populations (a comparative study) This research examines the energy practices of very poor women, men and young people living in informal settlements in peri-urban situations in Nigeria, South Sudan, Nepal and Bangladesh and how these are changing, drawing comparative lessons across the study countries. It challenges conventional approaches to energy transition research. Lack of access to clean energy limits economic development, stifles people's life chances and traps millions into extreme poverty. Sustainable Development Goal 7 makes bringing access to affordable, clean and reliable energy for the poor a necessary element in transforming the development prospects for the 1.4 million people currently without modern energy services. However, while considerable development activity is being devoted to bringing new technological products from renewable energy research centre laboratory benches into the affordable reach of the energy-poor, current approaches to energy transition are deficient, not least because they fail to take into account the specific contexts and needs of the poorest and most marginal groups in low income countries: the women, men and youth on whom we focus in this project.
