Biomass as the source of cooking fuel is one of the causes of indoor air pollution, desertification, soil erosion and other visual problems. The main aim of this study is to carry out a feasibility analysis in order to ascertain the possibility of conducting a study on the factors influencing household cooking fuel choice in Bauchi State. A total of 30 households were chosen systematically from the study area. A logit regression model was used to analyse the data. Cronbach's alpha value of 0.71 shows good reliability and acceptability as a valid study. Therefore, a study to analyse the determinants of household cooking fuel choice in Bauchi State is feasible and may provide conclusions relevant for policy making. Logit results show that income, number of rooms and nature of the home building are the variables that are positively related to the odds of adopting modern cooking fuel sources. Age of household head, gender of household head and home appliances are negatively related to the odds of adopting modern cooking fuel sources. Therefore, appropriate relevant policies will encourage households to adopt modern sources of cooking fuels.

Purpose The primary purpose of this study is to assess the factors that influence households’ choice of cooking fuel in Bauchi State, Nigeria. Design/methodology/approach In total, 750 samples were selected using multistage area cluster sampling, of which 539 responses were analysed. Multinomial logit model was used to estimate the factors that determine a household’s main cooking fuel choice in Bauchi State, Nigeria. Findings The result has shown that income, location, price of firewood, hours of electricity supply and home ownership are among the factors that have a significant impact on influencing the type of cooking fuel to be adopted by households. Research limitations/implications The study cannot offer any explanation about the influence of time dimension on the pattern of household cooking fuel choice in the study area. Practical implications Implementation of policies to increase the income of households, ensuring the availability of clean cooking fuel source and the increase in the price of firewood will encourage households to switch from using firewood to using cleaner fuel sources such as kerosene, electricity and gas. Originality/value This study has contributed to the existing literature on household energy choice by conducting a micro-level analysis of households’ cooking fuel choice in Bauchi State where a similar study has not been conducted. The study developed approximately 13 hypotheses (out of which two were found to be irrelevant) and added one new variable to test the impact of the neighbourhood’s source of cooking fuel on households’ cooking fuel choice.

The objective of this study is to describe the important factors affecting Malaysian palm oil industry especially biodiesel demand. To that end a market model representing palm oil production, import, world excess demand, domestic consumption, export demand, rest of the world excess supply and palm oil prices is formulated. A system of equations of eight structural equations and four identities is estimated by two stage least squares method using annual data for the period 1976-2008. The domestic price equation is formed to investigate the link between biodiesel demand and the Malaysian palm oil market. The domestic price is significantly affected by Malaysian ending stock, world palm oil price, biodiesel demand and lagged domestic price. The elasticity of Malaysian palm oil domestic price with respect to biodiesel demand is then obtained. Results suggest that biodiesel demand has a positive impact on the Malaysian palm oil domestic price. Thus, significant growth in biodiesel demand is important in explaining Malaysian palm oil price determination.
