Sumaya owns and operates a small neighborhood restaurant selling food and soft drinks. Two months after opening up shop, she bought two improved cookstoves. Before using the improved stoves, she used metallic stoves (un-improved stoves), spending 4,000 UGX (€1.04) on charcoal every day. Now, using the improved stoves, she is able to save 2,000 UGX (€0.52) daily - which adds up quickly over time! She uses her savings to improve her standard of living and support her family.
