Simulation Of Renewable Energy Exploitation In Rural Areas Based On System Dynamics (SD)--A Case Study In Rugao County In China

In a long time, the living fuel of Chinese rural was mainly depended on non-commercial energy resources such as straw and firewood etc. In recent years, with the rapid development of rural economy, great changes have taken place in the level and strucmre of the energy usage in rural family. And especially in economy-developed Jiangsu province, the demand for commercial energy resources increase rapidly, and it is accelerating to substitute for non-commercial energy resources such as straw etc. The substituted straw find no new usage way and they are causing new pollution. Based on the view of rural sustainable development, exploiting of renewable energy resources, optimizing of the consumption structure of rural living energy usage , efficiently utilizing of mineral energy and reasonably utilizing of a great deal of surplus agricultural waste have become a new subject of construction of rural energy resources at present.The paper took the example of Rugao county and based on the systematical analysis of the relationship among energy resources, economy and environments during the rural development and the sufficient survey of the supply and consumption of rural living energy usage, it built up the system dynamical model of the exploiting of rural renewable energy resources and the coordinated development of economical ecological environment. Through repeatedly simulating trials, it simulated in the condition of market economy the coordinated development trends of the exploiting of rural renewable energy resources, economy and ecological environment in future 30 years and analyzed the simulated results. The simulated results showed that in the view of optimization of energy resources structure and protection of ecological environment the renewable energy resources could not only provide clean and high quality energy resources, reduce the consumption of electrical power and liquid gas , but also reduce the exhaust of harmful gases such as greenhouse gases etc, and protect ecological environments . In the view of accelerating the development of ruraleconomy, the exploiting of renewable energy resources not only increase the food yield , but also promote the development of stockbreeding.
