Energy intensity, which shows energy efficiency of national wide, of Korea became better in the late of 1990. However energy intensity during 2008~2011 became worse. In this paper we made decomposition analysis for the surge of energy consumption and GHG emission in industrial sector who take main role in energy consumption of Korea during 2008∼2011. There are two time period, which are 1998~2007 and 2008~2011 in decomposition analysis. Production effect decreased energy consumption but energy intensity effect increased energy consumption. Structure effect in decreasing of energy consumption was lower than the other period. Iron industry and petrochemical industry who had constructed and added new facilities. And both of industries produce more much energy used products made energy intensity worse. Decomposition analysis for GHG emission showed that energy intensity effect and energy mix effect increased GHG emission. 우리나라의 에너지원단위는 1990년대 후반 이후에 개선되는 추세를 보였지만, 2008~2011년에는 악화되었다. 이에 본 논문은 우리나라 에너지소비를 주도한 산업부문을 대상으로 요인분해분석방법을 이용하여 에너지소비의 급등 원인과 온실가스 배출 변화 원인을 분석하였다. 요인분해분석의 대상기간은 1998~2008년, 2008~2011년의 2가지이며, 기간의 구분으로 에너지소비와 온실가스 배출에 영향을 미친 요인을 시기별로 비교하였다. 에너지소비 변화 요인을 경제성장(생산효과), 산업구조 변화(구조효과), 에너지효율(원단위효과)로 나누어 분석한 결과에 따르면 2008~2011년에 산업구조변화는 에너지소비를 감소시켰지만 에너지효율효과는 에너지소비를 증가시켰다. 산업구조효과에 의한 에너지소비의 감소추세도 이전의 기간보다는 둔화된 것으로 나타났다. 각 산업의 에너지효율 악화는 에너지원단위가 높은 철강산업 및 석유화학산업에서 설비가 신․증설되면서 에너지다소비제품의 생산량이 증가한 것에서 원인을 찾을 수 있다. 온실가스 배출 변화 요인을 경제성장(생산효과), 산업구조(구조효과), 에너지효율(원단위효과), 에너지원대체(에너지믹스효과)로 나누어 분석한 결과에 따르면 에너지효율효과와 에너지믹스효과가 온실가스 배출을 증가시킨 것으로 나타났다.

본 연구는 2015년 국내 2,325가구를 대상으로 에너지 소비 실태를 조사한 ‘가구에너지 상설표본조사’ 자료를 바탕으로 연료원별 난방용 에너지의 효율성을 비교 분석하였다. 전체 에너지 소비량 중 난방용 에너지 소비량 자료를 추출하여 확률경계모형(Stochastic Frontier Analysis)을 이용해 분석한 결과, 자료 처리 과정에서 문제가 존재했던 연탄 및 프로판을 제외하면 열에너지의 효율성이 가장 높았으며, 중질중유, 도시가스, 등유 순서로 효율성이 감소하였다. 이러한 효율성의 격차는 연료원별 차이뿐 아니라 주택 종류, 건축 연도, 주택 면적, 주택 소유 형태, 도시 규모, 소득 수준, 가구원 수 및 가구주 연령 등 다양한 요인에 영향을 받는 것으로 나타났다. 평균적으로는 중질중유, 열에너지, 도시가스의 난방에너지 효율이 높았으며, 이는 향후 국가 에너지시스템의 공급효율 개선과 에너지 소비효율 향상 측면에서 열에너지 및 도시가스 보급을 확대할 필요성이 있음을 시사한다. This study investigates the energy efficiency of heating demand by energy sources based on the “Household Energy Sustainable Sampling Survey” data of 2,325 domestic households in 2015. As an analysis result for efficiency of heating demand using stochastic frontier model, the consumption efficiency of heat energy is the highest when excluding briquette and propane, which had problems in data processing. The efficiency gap of energy consumption for heating demand is affected by various factors such as the type of housing, the year of construction, the size of the house, the size of the city, the income level, the number of households. On average, the heating efficiency of heavy oil, heat energy and urban gas was high, suggesting the need to expand the supply of heat energy and urban gas in the future in terms of improving the supply efficiency of the national energy system and improving the energy consumption efficiency.
