Abstract:
We used the whole life cycle theory to analyze the environmental assessment of wind power generation from 2011 to 2020, and studied the sensitivity of consumables emission coefficient and wind power installed capacity on pollutant emissions and carbon dioxide emissions. In addition, we predicted the full life cycle carbon emission intensity development trend of wind power generation by scenario simulation analysis and obtained the carbon emission reduction potential under different development scenarios. The research results show that:(1) The comparison of pollutant discharge intensity in each stage of wind power generation is: fan manufacturing stage> fan operation maintenance and transmission and distribution stage> wind farm construction stage> fan dismantling stage> fan transport stage.(2) The comparison of carbon emission intensity in each stage of wind power generation is: wind turbine manufacturing stage> wind turbine operation maintenance and transmission and distribution stage> wind farm construction stage> wind turbine transportation stage> wind turbine dismantling stage.(3) The proportion of negative carbon materials used and the metal recycling rate have a greater impact on the CO
2 emissions in the entire life cycle of wind power generation.(4) The full life cycle carbon emission intensity of wind power needs to be reduced to below 3.24 g/kW·h in order to help the power industry achieve carbon neutrality.
