The Direct and Indirext Household Energy Requirements in Korea from 1980 to 2000

초록

With growing income the household energy consumption increases rapidly, which holds especially for a fast growing country like Korea. Often analyzed is only the direct household energy consumption, which even excludes gasoline and diesel used by private cars. And such fuel uses are considered as part of the transportation energy consumption. The Korean household energy consumption (the energy consumption caused by the private consumption expenditure according to the National Accounts) was 74.785 Mtoe (Mega tons of oil equivalent, equal to 3,131.1 PJ, or 51.3 % of the country’s primary energy consumption of 145.683 Mtoe or 6,099.4 PJ) of which 33.505 Mtoe (1,402.8 PJ) was the indirect energy consumption, calculated according to the input-output tables for 1995. This paper aims to analyze by using a 168 sector input-output model changes in the energy intensities and in the composition of goods and services consumed by the Korean households for the period 1980 to 2000. The sectors analyzed are 161 non-energy sectors and 7 energy sectors, whereby 387 original non-energy sectors and 17 original energy sectors are merged to 161 non-energy sectors and to 7 energy sectors, respectively. Five yearly I-O tables for the years 1980, 1985, 1990, 1995 and 2000 at current and constant prices are used. Information on such changes is required to project future energy requirements as well as to formulate and implement energy conservation policy measures. Moreover, information on the energy intensities of goods and services expressed in kilocalories per unit of currency (kcal/Won) will be useful for consumers in making decisions on energy conservation. Often they do not know how much energy they use in consuming goods and services, which are not fuels or electricity.
