This study proposes an econometric analysis of household fuelwood demand in France. The choice concerning the energy used for heating is modeled, stressing the combination between one type of energy used as a main source and another one used as a back-up. This endogenous decision has an impact on fuelwood consumption and is taken into account to avoid biased estimates of price and income elasticities. The results show that the choice of energy mix is determined by the income and the socio-economic characteristics of households, and that fuelwood consumption is price-sensitive in the case where wood is the main source of energy.
