Household air pollution is a major health risk in South Asia. One of the most promising solutions to this problem is the introduction of improved cook stoves (ICS). However, the adoption of these stoves by Indian households has met with somewhat limited success and there are significant bottlenecks that continue to curtail the scaling up of ICS and related technologies. A new SANDEE study addresses the topic and may help assist Indian policymakers in encouraging the efficient utilization of renewable energy resources.
