 Biomass fermentation and gasification are two types of biomass utilization technologies for residential households. Government plays an essential role in the diffusion of improved technologies. Cost-effectiveness analysis can provide the cost and abatement potentials of each alternative under a single abatement strategy
  however, it is difficult for policy-makers to make an integrated assessment when multiple objectives are involved. This paper evaluates the performance of three distributed alternatives and two centralized alternatives for residential biomass use in rural China, including centralized biogas and centralized gasifier systems. An integrated assessment approach is built, which combines cost-benefit analysis, an entropy-weighting method, and a preference-ranking organization method for enrichment evaluations using the PROMETHEE approach. A total of 686 sample households in three regions of China were surveyed in this study. The centralized gasifier system and distributed household biogas were the top two alternatives for further development to meet the government?s 2020 development goal for biogas technology. The overall biomass utilization amount in the prioritized scenario is about three times that of the business-as-usual scenario by 2020. Furthermore, this study can provide significant insights for China?s policy-makers to draft strategic policies and countermeasures that will promote the development of renewable energy in China.
