Abstract

This study aims to broaden the model-theoretic and empirical knowledge on energetic geographic development processes. Therefore household surveys collected in three rural and penalized regions of China. The main focus of this survey is on the energy ladder model, postulating a higher degree of energetic sustainability when the income of population is rising. This survey tries to verify the model or rather point out parameters which cause regular deviations from the model. The model must consider regional, cultural and political characteristics coevally. The core of this survey is a data collection in 180 households. Besides demographic and microeconomic information the data collection particularly provides data on energy consumption (energy mix, energy efficiency, future energy-preferences etc.). Last but not least the environmental impacts of energetic use are determined by the appraisals of the concerned households. The descriptive and correlative data analysis provides insightful data for the following four explored sectors (1) „socio-economic situation“, (2) „energy use“, (3) „environmental awareness“ and (4) „demanded support“. The analysis allows conclusions on three different levels: a) a highly sophisticated picture of the selected regions emerges, that is presented by a multiple analogy among each other b) the overall data afford an overview of interactions between the essential parameters of the study: Those are energy use, energy efficiency, access to energy, environmental behavior, health and education c) on the basis of those two levels the following modification of the model is devised: The peripheral location, the cultural situation and the interventions from government as well as from civil society are parameters that significantly codetermine the choice for energy sources in rural areas. The analysis of demanded support in the energy sector as well as the conclusions of the families on environmental awareness establishes the basis for a row of suggestions of the author. Those suggestions shall allow a more sustainable energy use in the study areas. More participation, respectively a stronger comprehension of the rural population into the planning and development of energy supply systems is a very essential concern of the households. As an eminently sustainable technology the production of biogas is suggested within closed energy-nutrient loops (Integration of stables, toilets, green houses etc.). This can only be achieved by an intensive assistance.
