This paper introduces an approach to identify the total energy consumption with subsequent CO2 emissions, for both industrial and non-industrial sectors. Statistical data for 2005 were compiled in a national account system to construct an energy input-output table for investigating the influence between energy demand and supply activities. The methodological approach was applied to South Korea. Twelve types of energy and fifteen industrial and non-industrial sectors are formed as the compartments of the input-output table. The results provided quantitative details of the energy consumption and identified the significant contributions from each sector. An impact analysis on the CO2 emissions for the demand side was also conducted for comparison with the supply side.
Keywords: Decomposition analysis | Energy demand-supply | Energy structure | Input-output analysis
