Study on Beijing's energy utilization and forecast energy supply and demand based on grey model

摘要

Beijing is a typical city of energy resources shortage and there exists the contradiction between energy supply and demand. This paper analyzes the current situation and existing problems of Beijing's energy utilization, and then forecasts Beijing's energy supply and demand from 2011 to 2015 based on four kinds of grey forecasting models, finds out that the equilibrium of Beijing's energy supply and demand is fairly weak with higher external dependence and there is a large room for improving the proportion of quality energy and for developing and utilizing renewable energy. Finally, on the basis of the current situation of Beijing's energy utilization and the development trend in the next few years, some suggestions are proposed.
