A compilation and analysis of data on household energy in eight non-OPEC developing countries: India, Brazil, Mexico (limited to Mexico City), Republic of Korea, the Sudan, Pakistan, Malaysia, and Guatemala. The report explores the level and composition of total fuel consumption by households at different income levels within each country. Comparisons are made between urban and rural areas in the same country, as well as among countries. For Korea and Pakistan, the study further explores the effect of household size on energy consumption. In most cases, the data reflect consumption both of commercial fuels such as oil, coal, and electricity, and of so-called noncommercial fuels such as firewood, animal dung, and crop residues. The purpose is to bring the relevant data together for use in other research, to draw tentative conclusions regarding patterns of fuel use in the household sector, and to note the policy implications of those patterns.
