Clean Energy Substitution and Carbon Dioxide Emission Based on LEAP Model

The rapid economic growth and the continuous improvement of social development level not only increase energy consumption, but also lead to aggravation of environmental problems and damage the regional ecological environment. In addition, the increase in the use of fossil energy such as coal has led to more serious environmental pollution and continuous decline in air quality, making energy conservation and emission reduction work urgently needed. Since the LEAP (Long Range Energy Alternatives Planning System/Low emission analysis platform) model is suitable for analyzing the main sources of greenhouse gas emissions in the economic energy sector and the industrial non-energy economy, it can help local and regional economic sectors to analyze the emissions of air pollutants. Therefore, this paper uses this model to analyze the carbon emissions of S city. From the current status of carbon emissions in City S, it can be seen that although the carbon dioxide emissions from coal resource consumption in this city are on a downward trend, it is still necessary to find clean energy to replace coal resource consumption in S City. The study found that the natural gas reserves in City S are large, which is suitable for replacing coal consumption in industrial production in City S. The peak time of the city's total carbon emissions is between 2026 and 2036, and the peak size is between 227 and 475Mt. The city's industrial sector production process. The peak time of CO2 emissions will be earlier, and the peak size will decrease by 118Mt. In the prediction and analysis experiment of future carbon emission peaks in City S based on the LEAP model, through the application of low-carbon technology, the use of clean energy It can reduce the peak carbon emission, which is conducive to the realization of energy saving and emission reduction.
