Research on the Assessment of China's Energy Security Risk and Grey Model Based Early Warning System

The energy safety risk early warning system was designed with the classification of primary energy structure. The energy system was divided into two levels, including a total of 37 indicators. The China's energy risk early warning system was established using the method of fuzzy comprehensive evaluation and entropy weight combination. The demonstration analysis was conducted using the data from the year of 1995 to 2008 and it was concluded that the energy security situation was relatively stable in the recent years. The entire situation of energy security of China during the year of 2009 to 2010 was predicted based on grey model and the conclusion that the energy risk early warning index was between the worthing attention and danger and only coal sub-system was in a safe state.
