Switching entirely to LPG to meet household energy needs is one way of reducing indoor air pollution. It also has the additional benefits of facilitating convenience in cooking and saving cooking time. Although there are a number of reasons why many households do not use LPG, the primary reason is that the poor cannot afford it. The Andhra Pradesh government has launched an innovative, targeted subsidy programme - the Deepam scheme - to encourage the LPG consumption among low-income households.
