The effects of rwanda's biogas program on energy expenditure and fuel use
World Development , Volume 67 p. 461- 474
Dependence on biomass to meet domestic energy needs raises several socio-environmental concerns. In contrast, cattle manure, which may be used to generate biogas, is considered a cleaner and cheaper energy source. Despite several initiatives toyears of education promote biogas, systematic analyses of its effects are limited. This paper uses data from Rwanda to examine the effects of participating in a biogas program on energy-related expenditures and consumption of traditional fuels. We find evidence of substantial reductions in firewood use and large savings. However, the attractiveness of the program is hampered by a long payback period and low rates of return.
