In considering of high proportion of renewable energy supply in 2050, the accelerating of energy\nconsumption gross, source and environment can affect the energy system restrict affection are\nstronger. Add wind and solar to electricity energy with large amount of energy source exploitation.\nThe energy source amount per person is lower. Considering the renewable energy amount and\nsupply, primary energy storage and structure problem is standing out. Before the wide spread of\nrenewable energy, Using the high-carbon energy in China can pollute seriously. Chinese energy\nsupply and demand problem is research key point. This paper researches Chinese energy supply\nand demand pattern system and evaluation methodology, gives out the inner and outer influencing\nelements. And evaluate Chinese energy supply and demand pattern from energy gross, structure,\ndistribution and transportation. Use energy supply synthesize radar comparison chart in\ncertain time period. From energy security, economy, clean and efficiency, analyze the benefit\ncomparisons of Chinese energy supply and demand pattern. This energy supply and demand pattern\nmodel will give one certain theoretical analysis and practice reference to the further high\nproportion of renewable energy.
