Biomass Utilization.

 

The end of 2006 the country has been building in rural areas 18.7 million household biogas digesters, sewage purification digesters 140,000, livestock farms and industrial waste biogas 2,000 locations with an annual output of methane about 90 billion cubic meters, nearly 80 million rural population provides a better quality of life fuel.

 

China has developed a variety of fixed bed and fluidized bed gasifier, to straw, sawdust, rice hull, branch gas as raw materials.

 

In 2006 for drying wood and agricultural products more than 800, village-level straw gasification gas system near 600, the annual production of 2,000 million cubic meters of gas from biomass.

 

Geothermal energy. Earth's interior heat source can be different from the gravitational tidal friction, chemical reactions and the energy released by radioactive decay and so on.

 

The main heat source of radioactive energy is the Earth.

 

Rich in geothermal resources in China, widely distributed in hot spots have been 5500, 45 geothermal field, geothermal resources, total about 320 megawatts.
