Globally, 1.4 billion people lack access to electricity and an estimated 2.7 billion rely on traditional biomass – wood, charcoal, animal waste and agricultural residues – for cooking and space heating. Roughly one third of this population lives in rural India. Over the past two decades, considerable efforts have been made to introduce improved cookstoves and/or cleaner cooking fuels in India, but as in other countries, these interventions have largely failed to bring about a large-scale transition towards cleaner, more “modern” cooking technologies.
