The National Programme on Improved Cookstoves (NPIC) was started by the Ministry of Non-conventional Energy Sources (MNES), Government of India, in 1985 to achieve the twin objectives of fuelwood conservation and smoke reduction in kitchens. NPIC has overseen the installation of 28 million improved cookstoves, saving nearly 20 million tons of firewood per year. These achievements, though seemingly impressive, are not realistic as they are based on certain assumptions, particularly regarding the life expectancy of stoves. This paper examines the various assumptions made in such calculations and tries to arrive at some realistic numbers regarding fuelwood savings, which can be used to evolve a policy for refining the NPIC further.
