This study evaluated the cooking energy costs and efficiencies, the air pollution impacts of cooking energy consumption and the impact of the energy policy in the cooking energy sector in Nigeria. Water boiling and cooking experiments using the common cooking energy sources (fuel wood, kerosene, liquefied petroleum gas (LPG) and electricity) and common food items (water, yam and beans) were carried out. Energy surveys were carried out to determine the cooking energy use patterns in the urban and rural areas. It was found that fuel wood is the least expensive cooking energy source and LPG is the most expensive. Energy use efficiencies for boiling water were estimated at 25%, 46%, 73%, 79%, 66% and 90% for fuel wood, kerosene, gas, electric immersion coil, electric heating coil and electric hot plate, respectively. Energy intensity was found to be a comparative measure of energy efficiency. The impacts of air pollution from household cooking suggested a possibility of significant air pollutants contribution to the ambient environment using any of the energy carriers considered except electricity. The cooking energy use patterns showed that fuel wood is the predominant energy source for cooking in the rural areas while kerosene is the predominant energy source in the urban areas, revealing that the energy policy in the country had made no impact in the cooking energy sector. Recommendations for improving the energy supply situation were given and for removing the barriers that prevent the implementation of the recommendations. © 2006 Elsevier Ltd. All rights reserved.
