This paper discussed three power generation technics including biomass combustion electricity production,biomass gasfication electricity production and methane electricity production,and analysed their recent advances and prospects.

Impact of biogas project on ecological animal husbandry system;

Role of biogas project on purifying living sewage in new countryside construction and some countermeasures;

Symbiosis effect of rural biogas project;

Analysis on biogas engineering mode of large & medium-scalehusbandry farms and investment results;

The benefit of the biogas engineering lies both in the input side and output side.

Biogas engineering in China has made a great progress in the past decades.

Methane electricity generation is an important measure for constructing the green environment protection engineering,with great potential for development.

The application and prospect of methane power generation technology and methane fuel cell;

As a short-term objective,biogas power generation and vehicle biogas production will be increased continuously;and as a long-term objective,biogas fuel cell technology and biogas chemical industry should be developed to improve the utility value of biogas.
