In sub-Saharan Africa, 70% of the population is still dependent on the traditional use of solid biomass (wood, animal dung, charcoal, and coal) for cooking. Dependence on these fuels has many adverse impacts on peoples health as traditional biomass cookstoves is estimated to have caused almost 600,000 deaths in 2012; and on the environment as the emission of black carbon is contributing to global warming. Acknowledging this problem, African Clean Energy (ACE) has started to provide smokeless and sustainable cookstoves for those who need it the most.
