In her May 23 news story, "In Africa, Lifting the Pall of Smoke From Cooking," Susan P. Williams emphasized the severity of indoor air pollution in developing-world households. Charcoal has been suggested as a remedy because it burns more cleanly than nonprocessed biomass fuels. However, the appetite for charcoal has also been a major cause of deforestation across Africa.
Alcohol fuels can respond to the scope and scale of the household energy problem in Africa while creating a market for agricultural waste and flared (and noncommercial) natural gas. Both ethanol and methanol can be locally procured in Africa and are affordable, clean-burning and safe.
