This study showed that socio-economic and demographic characteristics of households are important determinants of biogas adoption behaviour. Some proactive policy issues could be drawn from these results when designing programmes for promoting biogas energy. First, the negative correlation of age of household head with the adoption of biogas technology is crucial regarding the categories of households to be targeted. Those involved in technology development and dissemination have long believed that new technologies should be targeted at mature heads of household, mostly over 50 years old (Somda et al., 2002). Thus the focus is more on those who it is hoped will adopt the technologies than those who actually will do the adopting (Koppel, 1985). Our results suggest that the younger generation is central in the biogas technology transfer process and therefore the earlier they are involved in biogas planning and development, the faster and better could be the outcome of this process.
