Professor Kirk R. Smith in an editorial in Science:
Along with advanced biomass combustion, biogas, liquefied petroleum gas, natural gas, and other clean fuels, electric cooking needs to be directly incorporated into modernization plans for the world’s poorest people.
For those worried about CO2 emissions from power plants, consider that modest efficiency measures that reduce 3% of electric power consumption in rich countries (which are also largely supplied by coal) would “free” enough electricity to supply half of all biomass households with induction stoves. New supplies of electricity would produce far less than a 1% increase in global CO2 emissions.* It is not the cooking of the poor that threatens the climate.
Switching from solid to clean forms of energy can bring more health benefits than nearly any other modernization, including clean water and sanitation.† It is too early to tell whether induction cooking can be successfully promoted in biomass-using rural areas, but not too early to predict that electric cooking appliances will be attractive to people as electricity becomes more reliable. Although in one sense the most mundane of energy issues, given that billions do not use modern fuels in their households and suffer great impacts on health, welfare, and the local environment as a result, finding solutions for providing electricity has important implications for global health and sustainable development.
