Abstract: The researches on national energy structure are based on the simple ratio relationship and qualitative analysis for the complexity of affecting factors. The paper tries to fill the gap by studying the energy consumption structure by informational entropy theory and the principle of Maximum Informational Entropy. It introduces informational entropy theory briefly first, and then introduces it into the energy consumption structure research and designs the indicators of equilibrium and dominance degree to describe energy consumption structure quantitatively. In the end, the paper provides a simple demonstration that takes proved reserves into consideration to analyze the feasibility of the method. The demonstration analyzes the changes of the entropy indicators of China energy consumption between 2001 and 2006, and finds that much coal consumption is not the controlling matter. So it is important to research on improving coal efficiency and clean utility in energy planning and development on this condition.
