Survey of rural household energy consumption in China

Based on comprehensive energy surveys of 3240 households in six different regions, we present the level and structure of rural household energy consumption. There are large differences among regions which depend on locality and availability of fuels. Energy consumption per household accounts for 700–1200 kgce (we use 7000 kcal/kgce), 40–60% of which is used for cooking; 60–90% of total household energy consumption is in the form of biomass. The average energy-conversion efficiency using biomass fuels is in the range 10–20%. Where the strain of traditional patterns of biomass use on the resource base became too severe, the balance between local agricultural and hillside ecosystems has unraveled and caused accelerating destruction of limited land resources. Higher income households need more commercial energy, especially in the form of electricity. Rural household energy will continue to depend mainly on biomass.
