Accelerated deforestation and scarcity of fuelwood have, in recent years, created a need for governments of developing nations to find policy alternatives that reduce demand for fuelwood and thereby reduce pressure on forests. This study sought to examine energy consumption patterns in a cross-section of rural households in Kenya and to analyze how these use patterns relate to socioeconomic, demographic, institutional and energy market factors. The models specified were demands for fuelwood, charcoal, kerosene, commercial heat energy and aggregate energy. For fuelwood, a probit analysis was utilized to determine the conditional probability of fuelwood consumption and a least squares regression to determine quantity consumed. Ordinary regression was used to estimate demand for the other fuels. Indifference curve theory was used to show fuel choices by different income groups. High income households continue using a small amount of fuelwood because of unique attributes. The results for low and middle income households indicate that fuelwood use per household increases with more income, but, among high income households, fuelwood use declines with increase in income. The research indicates that household incomes, family size, improved ceramic stoves, other fuels, and occupation are the most influential variables on consumption of various fuels. The quantities of fuelwood, charcoal and kerosene consumed are not very responsive to changes in income. Aggregate energy is income inelastic and a ’normal’ good while woodfuel and kerosene are ’inferior’ products. The model indicates that redirection of a 10 percent increase in income so that only the low income households benefit would cause only a small, 1 percent, increase in fuelwood consumption. A program that tripled the fraction of households having improved ceramic stoves would lead to a predicted 3.8 percent reduction in the amount of fuelwood consumed. At the current rate of growth in Kenya’s population (4 percent per year), fuelwood consumption is projected to increase from 16.51 m. tons (1986) to 33 m. tons in the year 2000 for rural Kenya.
