The paper retraces the implementation of a biogas energy programme within the Best Ray project run in Tanzania 2008–2011. The objective of the Best Ray project was to empower rural communities by providing them with modern and renewable energy technologies to better tackle Millennium Development Goals. An important activity of the project was the construction of a biogas system in secondary school solve a sanitation problem and provide the school with a free and reliable energy supply. After a field assessment, the project directed the resources to small domestic biogas installation rather than large institutional ones as future sustainability seemed to be better granted. Best Ray merged the Tanzanian Domestic Biogas Programme. Trainings were organized and 25 biogas plants constructed. The technology is simple and the design effective, but still the cost seems high for a rural context. Final beneficiaries are appreciating the technologies for reasons that were not predictable by those who ideated the project.
