The study investigated Maputo citizens’ decision to switch to clean energy. To measure residents’ intention and behavior, the study used Ajzen’s theory, suggesting that attitude, subjective norm, and perceived behavioral control influence intention and behavior. About 300 responses were analyzed using structural equation modeling. The survey revealed that perceived behavioral control was the best predictor of intention and behavior, and suggested that to encourage a widespread transition to sustainable cooking energy, policymakers should focus on increasing awareness of the benefits of this transition, making these energy sources financially accessible and providing education on the safe use of associated equipment.
