Optimization Of Energy Structure In Tianjin From The View Of Low-Carbon Economy

Climate change and greenhouse gas emissions has become widespread concern of the international community .Energy structure adjustment and low-carbon technology development are the effective measures to address this issue.To achieve the pueposes of improvements in Tianjin coal-based energy supply structure, reduce environmental pollution, improve energy efficiency and ease pressure on energy supply, this article from low-carbon perspective analysis to the energy structure of Tianjin,and on this basis done a lot of preliminary research work for the 12th five-year-plan scheme of address climate change and low carbon economic development of Tianjin.This article not only analyze the energy structure of Tianjin use traditional gray system theory ,but also innovation from the following two aspects: First, evaluate the carbon dioxide produced by renewable energy by life cycle assessment(LCA), and computing devices running on the carbon dioxide produced during the recovery period; Second, simulate the future development of Tianjin energy structure use system dynamics approach, then compare the greenhouse gas emissions and energy consumption through non-carbon model, low-carbon model and strengthen low-carbon models to find the best model for energy structural adjustment of Tianjin.Results showed that relative to non-carbon model it can saving 15 million tons of standard coal and reduce emissions of 7.6 million tons of carbon dioxidein in strengthen low-carbon model in 2020,and the unit GDP energy consumption are significantly lower.It can achieve the target that the unit GDP carbon dioxide emissions intensity reduced to 45% to 50% by 2020.
