Analysis of the Relevancy between Energy Consumption and Environmental Pollution Based on Grey Theory

In order to analyze the relationship between energy consumption and environmental pollution, grey theory has been applied. By making use of the correlative statistic data, inherent grey relevancy between energy consumption and environmental pollution of China has been discussed as an example, and different impact degrees that various energies consumption have on environmental quality of China has been ascertained by calculating the grey relevancy degree. The results show that fuel oil, coal, coal oil, crude oil and gasoline are the energy varieties that have great impact on environmental quality, while natural gas has less impact on environmental quality. In the end, energy consumption development strategies that can improve environmental quality have been put forward to offer scientific gist for adjusting energy consumption structure, improving environmental quality and actualizing sustainable development between energy consumption and environment.
