A Study on the construction and application of fossil energy Input-Output table (in Korean)

Whether domestic or foreign, 'Energy Input-Output Table' prepared and used currently has a limitation of having not eliminated the portion of primary energy used as materials, so called embodied energy. If embodied energy is not eliminated, energy consumption by industry will appear to be excessively bigger or smaller than the actual consumption. In this study, we have presented an alternative solution to overcome such a limitation and constructed '2005 Fossil Energy Input-Output Table' of Korea. We have also analyzed fossil energy consuming structure of Korean industries from the table. When we compared the improved method of eliminating fossil energy used as materials from fuel consumption to the conventional methods, it showed a difference of about 3.8 times in petroleum/coal industry and also showed considerable differences in non-metal, electricity/gas/water service industry and so on. Meanwhile, when we calculated the intensity of fossil energy using 'Energy Input-Output Table' prepared by the improved method, it appeared that 5.6 TOE of fossil energy on average has been consumed to produce products or service worth 100 million KRW in 2005 in Korea. By industry, 78.5 TOE was consumed to produce 100 million KRW in electricity/gas/water service industries which include thermal power generation and 24.5 TOE was consumed for transport/storage industry. And the result of analyzing direct and indirect energy consumption through inter-industry analysis showed that, while the industries of cement and electric power industries mostly use energy directly, those of construction, automobile and machinery industries usually use energy indirectly.
