Abstract: Given their consequences on human health, indoor air pollution generated through domestic energy consumption is more important than outdoor pollution in the third world. The understanding, however of the intricate link between energy and health lags behind that of the linkages between water or waste management and health. The consequences of energy consumption have not been reflected in health care priorities in most countries. Apart from studies that examine the relationship between poverty and energy, studies are also scanty in the identification of both area and structural characteristics of urban population in relation to energy use. This study identifies the nature, types and sources of energy used by households for domestic purposes in Ilorin, Nigeria. The specific tasks of the study include establishing a spatial pattern of the variation in the types and quantity of energy used by households so as to obtain a gradient of the characteristics of energy consumption in cities of developing countries. This is expected to lead to a corresponding variation in the health consequences resulting from the use of such energy types. These tasks will enhance a clearer understanding of the link between energy and city wide environmental health. Multiple Regression analysis and other relevant statistics would be used to determine the relative contributions of household characteristics to the pattern of energy use. The sources of data are primary and secondary.
