Fuel stacking is the phenomenon of households simultaneously using a number of different fuels, often ranging from collected wood fuel, to kerosene, LPG or electricity. Fuels sticking can exist both for lighting (kerosene and electricity) and cooking (wood, LPG, kerosene, electricity). Our field studies in Lalitpur  and Rupandehi Districts of Nepal and Wayanad District of Kerala and Koraput District of Odisha in India, have shown that fuel stacking is a fairly common phenomenon.
