The report analyzes the energy consumption of Tanzania's urban informal sector, focusing on subsectors such as food preparation, beer brewing, grain milling, carpentry, metal working, and auto repairs. It finds a dichotomy between subsistence-oriented activities using traditional fuels and small-scale businesses using modern energy. The study highlights that the most energy-intensive subsectors, particularly food preparation and beer brewing, are the least efficient and the least capital-intensive, often serving as employment buffers for women. Overall, the informal sector's energy use is limited by capital constraints, meaning it provides significant urban employment without substantially increasing total urban energy consumption.
