Abstract The structural contradictions are mainly shown as the energy bottleneck in China. Based on theory of energy economics, this paper puts forward three dimensions which are social and economic development, energy development planning as well as environment, from the perspective of requirements of low-carbon economy to energy structure. By analyzing elements of the various dimensions, it identifies fifteen measurement indexes by one-sample T test with SPSS16.0, and calculates the weight of each index with Analytical Hierarchy Process (AHP). Based on this, Energy-Economy-Environment (3E) model is built to empirically analyze sanity degree of energy structure from 2002 to 2008, in China. It is found that the changing trend of sanity degree of energy structure shows “U” shape, first decreasing and then rising. The energy structure plays more and more important role in meeting social and economic development while the enforcement of energy development planning and environmental improvements is to be improved.
