A multi-objective analysis of cooking-energy alternatives

Fifteen cooking energy sources have been evaluated using nine objectives representing the energy-economy-environmental system. Scenario development and a sensitivity analysis have also been performed. While lignite, LPG, natural gas, biogas, solar thermal, and decentralized electricity generation from fuelwood gasification are preferred, the use of kerosene and fuelwood requires efficiency improvements of cook stoves. Coal, soft coke, charcoal, photovoltaics, grid electricity, and electricity generated from biogas or diesel have not been preferred due to either high costs or low efficiencies.
