The International Energy Agency’s World Energy Outlook has been publishing on the number of people relying on the traditional use of biomass for cooking since WEO-2002. Here we present regional aggregate results from our WEO-2013 database*. Our database on the traditional use of biomass for cooking makes use of the World Health Organization’s (WHO) Global Health Observatory estimates of reliance on solid fuels. In line with the level of data available from most sources, it focuses on the population where solid fuels are the primary fuel for cooking. Precise numbers on stove type or quality and on secondary sources of fuel for cooking are not available for most countries.
