The level and structure of rural energy consumption have been changing greatly in the developed region of China, where the economy is growing rapidly. The growth of rural industry is giving rise to a substantial increase in energy demand. The availability of reliable and secure energy supplies...

A stratification sampling method has been applied to investigate 384 households in 12 villages of four towns in Yangzhong county. Responses to a questionnaire show that the average annual energy consumption per rural household is 298.7 kgce (we use 7000 kcal/kgce), with average energy of 0.59...

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...

In order to classify regional types of rural household energy consumption (RHEC) in China, this paper selects the following as the characteristic indices for regional classification: per-capita available heat consumption for cooking and heating per day (PCAHC), annual per-capita electricity...

During the development of biogas digesters, a problem, which is how to appraise the economic benefits, always exists. This paper mainly discusses the necessity of cost-benefit analysis on biogas digesters, clearly defines some vague concepts during the analysis, tells how to quantitatively...

During the development of biogas digesters, a problem, which is how to appraise the economic benefits, always exists. This paper mainly discusses the necessity of cost-benefit analysis on biogas digesters, clearly defines some vague concepts during the analysis, tells how to quantitatively...

A basic feedback structure of rural energy-economy system is approached in this paper based on systems engineering and system dynamics (SD) principles. The dynamics simulation model in then developed and applied in analyzing the energy construction of Shouyang County, Jiangsu Province in China....

Development of household biogas digesters in rural areas and integrated use of agricultural wastes has changed the structure of rural household energy consumption and greatly increased the application of highly efficient organic fertilizer, improved soil fertility and promoted sustainable...

This article discusses biomass resources and its consumption in China's farming area. In 2000, the annual yield of crop-straw was about 6900 Mt, of which 54% could be used as a source of energy. The reasonable supply of firewood was about 150 Mt. The total consumption of biofuel in China's rural...
