An international comparative analysis aimed at perspectives on China's energy development scope is presented in this paper. By comparing the development course of the energy consumption of the United States, Canada, Europe and Japan, we find that although these countries have achieved the same level of development, they have made major differences in per capita energy consumption. Based on this, we propose the concept of "two types of developed countries", which we describe as "America and Canada model" and "Europe and Japan model "(the latter can be further broken into the "Europe model" and the "Japan model"). The reasons for the consumption differences of the different models are analyzed separately in industry, transport, residential, commercial and public services end-use sectors. In conclusion, based on the comparative analysis of those developed countries and China's actual conditions, the paper proposes that China's growth scope of per capita energy consumption is less than her per capita energy consumption in 2010, and several suggestions for the energy development are given.
