Abstract: In correlated consideration of the extra generating variables such as the resources of rural energy, the development of rural economy and the supply of rural energy, the paper presents the rural energy development strategy in PRC. The paper suggests to establish a stereoscopic rural energy engineering system of open type. This syetem will be made up of rural interregional energy supply net work and government energy supply network. The mainstay of the energy supply in the rural area of China will be the small hydro-power, small-scale coal mine and biogas.The idea of the mainstay of energy supply does not mean the only energy supply by these three energy resources to solve the rural energy shortage problem in China. The real meaning of the mainstay is that these three energy resources are reliable, easy to obtain and exploited in a short period. Surely the solar energy, wind energy, geothermal energy and those energies supplied by State commercial commoditiesare also the energy resources for rural area area but the productivity of State commercial commodities and the level of technical development of new energies impossible to reach the required proportion of the rural energy supply at the end of this century To develop these three energy resources as the three mainstays will benefit the ecological balance and tne development of ecological energy indirectly.
