  • 요즈음 국제 에너지 회의 등에서 에너지가 더 이상 공공재가 아니며, 소비재로서 적정한 서비스 대가를 받아야 한다는 지적이 자주 거론된다. 그동안 경제성장 과정에서 우리 제품의 해외 가격경쟁력을 높이기 위해 정부가 에너지 가격을 인위적으로 낮게 추진해온 바 있다. 이 같은 저에너지 가격정책이 에너지 과소비와 비효율적 사용을 부추긴 원인의 하나였다고 볼 수 있다. 최근 국제 경제위기가 촉발된 '97년 말부터 에너지 가격이 폭등하였는데, 이것이 비록 정책적인 원인에 의한 것이라기보다는 환율 급등에 따른 것이었지만, 그 여파로 에너지 소비가 줄어드는 현상이 나타나게 된 것이 이점을 증명해준다 하겠다.

  • In order to obtain practical information for efficient energy usage in sterilization, energy consumption was monitored for various processing variables, i.e. heat transfer type (conduction and convection), can size (No. 202-2, No. 301-3, No. 301-7, and No. 603-2), retorting temperature $(110^{\circ}C-121^{\circ}C\;and\;130^{\circ}C)$, and sterilization method (steam, and hot water sterilization). Less energy was consumed for smaller can size and higher temperature, and this trend was more distinguished in conductive food than convective food. Hot water sterilization could lower energy consumption in conductive food, but not in convective food. Energy consumption data of this work was reasonable when compared with energy consumption of sterilization in canneries, and therefore thought to be able to be used for estimation, design and optimization of energy consumption in sterilization.

  • The amount of energy consumed by a transportation system in a city is influenced not just by a transportation system itself but also by city's spatial character. Yet there have been very limited studies on this subject. This study investigates the factors that influence the energy consumption by a transportation system and city's spatial character. The model of an urban area confined within a definite boundary is assumed in order to develop the relationships between the energy consumption and the transportation system. Various assumptions on the character of a city and activities are made. An equation for computation of the energy consumption is derived with such factors as modal split, densities of residents and workers, as well as technological development. Using the equation, sensitivity analyses are performed in order to identify the relationships between energy consumption and influencing factors. It is found that the modal split is the most powerful factor that determines the energy consumption by the transportation system. Yet it is also found that the densities of residents and workers and the technological factors are very important in determining the amount of energy consumption as well.

  • Although energy demand management policy attracts attention internationally and domestically, the importance of local government in this policy is not so much as central government. But local government can do a role with regard to this policy because it is close to energy consumers not like central government. So local energy plan should be based on the understanding local energy consumption characteristics to activate local energy demand management policy. This paper tries to analyze energy characteristics of 16 local governments by decomposing energy consumption into population, production and intensity factors. The result of index decomposition analysis shows that energy intensity improvement has offset the increase of energy consumption caused by economic growth in the metropolitan cities, while it couldn't offset in the other provinces because of industrialization based on the manufacturing. In conclusion, this paper suggests that it will be necessary to switch to low energy society by carrying out concrete energy efficiency improvement projects in the metropolitan cities while it will be helpful to make a local development plan for low energy intensive industrialization in the other provinces.

  • 전기는 생산 공급하는 전력회사와 사용, 소비하는 수용가 사이에 전기사용량을 계량하여 요금을 부과하는 장치로서 전력량계를 수용가에 부설하여 소비하는 전기에너지를 측정하고있다. 전력량계는 수요가가 부하에서 소비하는 전기에너지를 사용시간에 따라 전력을 적산하여 전기요금을 계산하는 계량장치로 기계식과 전자식으로 구분되어 있으며 이들두방식을 혼용한 반전자식이 있다.

  • The purpose of this paper is to analyze of the home energy consumption and conservation awareness, usage patterns and policy directions for housing energy-saving house by three types of houses tenure. The results of analysis is : First, there is existed to the difference in average by each housing tenure types. Second, the residents of sales apartment and tenants of private and public rental apartment are practices in the energy consumption and conservation Third, the behavior between residents of sale-housing and the tenants of private and rental housing on the energy-saving behavior items is existed with behavioral differences. Finally, the consumer-oriented incentives method in the future housing energy' policy direction might be used more efficient and effective than others
