Greenhouse Gas Emission Mitigation of Global Automotive Manufacturing through Clean Energy Supply

摘要

Automotive manufacturing is energy-intensive. The consumed energy contributes to generation of significant amount of greenhouse gas (GHG) emissions from automotive manufacturing industry. In this paper, a study is conducted on assessing the application potential of such clean energy power systems as solar PV, wind and fuel cells in reducing the GHG emissions of global auto manufacturing industry. The study is conducted on those representative clean energy systems available on the commercial market at six global locations. The results demonstrate that wind power is superior to other two clean energy technologies in the economic performance of the mitigation effect. Among these six selected countries, the highest mitigation potential of GHG emissions is in China, through wind power supply. The maximum GHG reduction can be made up to 60 tons per $ 1000 economic cost investment on wind energy supply in China. The application of wind power systems in the United States and Germany may also obtain a maximum of GHG reduction between 40-50 tons per $1000 economic input. When compared with the wind energy supply, applications of solar and fuel cell power systems have much less potential for GHG mitigation in the selected six countries. The median values of GHG mitigation range resulting from solar and wind power supply are almost at the same level.
