  • Due to climate change, population growth, and economic development, the demand for water in the urban water system (UWS) and the energy required for water use constantly increase. Therefore, beyond the traditional method of considering only the water sector, the Nexus approach, which considers synergies and trade-offs between the water and energy sectors, has begun to draw attention. In previous researches, the Nexus methodology was used to demonstrate that the UWS is an energy-intensive system, analyze the water-energy efficiency relationship surrogated by energy intensity, and identify climate (long-term climate change, drought, type), geographic characteristics (topography, flat ratio, location), system characteristics (total supply water amount, population density, pipeline length), and operational management level (water network pressure, leakage rate, water saving) effects on the UWS. Through this, it was possible to suggest the direction of policies and institutions to UWS managers. However, there was a limit to establishing and implementing specific action plans. This study built the energy intensity matrix of the UWS, quantified the impact of city conditions, external influences, and operational management levels on the UWS using the water-energy Nexus model, and introduced water-energy efficiency criteria. With this, UWS managers will be able to derive strategies and action plans for efficient operation management of the UWS and evaluate suitability and validity after implementation.

A Study on the Night Thermal-storage Power Service : Sustainability and Energy Security (심야전력제도의 문제점과 개선 방향 : 경제성·환경성·형평성 및 에너지 안보)

  • This paper analyses the Night Thermal-storage Power Service(NTPS) from the perspective of sustainability. It investigates the economic, environmental and social aspects of NTPS, thereby reveals that NTPS triggers the inefficient use of fuel, the increase of carbon dioxide emission and the increase of cross subsidy between consumers. This paper also analyses NTPS from the perspective of energy security. It investigates how NTPS makes LNG demand volatile in winter, thus threatens our energy security. According to the analysis, NTPS directly violates two basic principles of national energy policy; Sustainability and Energy Security. To solve these problems, not only the harmonized adjustment of Heating Oil Tax and Electric Power Rates is needed to curb the rapier increase of NTPS, but also another separate policy is necessary for converting the electric heating system based on NTPS into the one based on Heating Oil.

  • This paper is to analyse a changing space of energy flows in Northeast Asia from geopolitical and geoeconomic perspectives that have been recently promoted for energy security of countries in this region. The research is based on an analytical framework in an integration of political ecology and political economy. Because of an ever-increasing input of energy resources for economic growth and of dramatically increasing price of crude oil and recent instability of oil market, South Korea, China and Japan have been deeply concerned with energy security and conducted very actively geopolitical strategies. And hence the space of energy flows in the region is now in a process of dynamic reconfiguration, in which the project for development of oil and natural gas fields in East Siberia and construction of pipelines to transport them can be seen as one of competitive issues among these countries. In spite of worrying about stagflation due to rapid increase of oil price, such geo-strategies for energy security and reconfiguration of space of energy flows seem to keep the accumulation of capital in this region continue with generation of huge privatized oil companies.

  • 에너지경제연구원에서 최근 발간한 '에너지수요전망(2001~2006)'에 따르면 우리나라 에너지수요는 향후 5년간 과거의 높은 증가세와는 뚜렷이 구별되는 안정화 추세를 나타낼 것으로 예상된다. 지난 10여년간 우리나라의 에너지소비는 낮은 수준의 에너지가격 지속과 경제성장 및 생활양식 변화를 배경으로 매우 빠른 속도로 증가해 왔다. 그러나 향후 경제성장 속도가 과거에 비해 둔화되고, 에너지안보 및 국제적 환경규제 대응 차원에서 에너지의 효율적 사용이 중요해 짐에 따라 에너지수요는 안정적인 증가추세로 접어들 것으로 전망된다.
