Three main ways of how renewable energy is currently used in rural China are described in detail: biomass energy, solar energy and small hydro-power. The difficulties faced in their promotion are analyzed, such as lack of policy, lack of technical personnel, single financing channels and inadequate research efforts. Some constructive suggestions are provided, which have important theoretical significance and practical value for developing renewable energy in rural China.

Biomass energy as a renewable energy increasingly attracts global attention. An in-depth applied research was made on biomass energy for cooking in China's rural areas in this paper. And a novel biomass semi-gasification technology was proposed. This technology does not produce tar which causes serious environmental pollution compared with the biomass gasification technology, and has higher efficiency than the biomass direct combustion technology. This technology has a strong theoretical and practical significance in optimizing the rural energy structure, improving the rural ecological environment, and improving the production and living quality of the farmers in China.
