지난 10월 14일 서울 삼성동 코엑스홀에서 공공 및 민간부문 에너지관리자, 산업체, 건물 에너지 절약업무 관계자, ESCO업체 관계자 등 100여 명이 참석한 가운데 우수 ESCO 기업으로 선정된 (주)에너지솔루션즈와 한국하니웰(주)에 대한 시상, 두 기업의 우수사례발표, ESCO 사업 활성화 방안을 발표하는 시간을 가졌다. (주)에너지솔루션즈는 국민연금 강남사옥과 서울대학교, 웅진에너지(주)의 냉난방설비 및 수축열시스템 사례를, 한국하니웰(주)은 산업체의 공정개선 및 건물에너지절약 투자사례를 발표하였다. 참석자들은 기업의 실제 우수사례 공유를 통해 유용한 정보를 획득할 수 있는 뜻깊은 시간이었다고 평가했다. 에너지관리공단 관계자는 "오늘날 에너지효율향상은 저탄소 녹색성장을 위한 핵심이자 기업의 경쟁력과도 직결되고 있다"며, "기업의 에너지절약과 경제에 도움을 주는 ESCO 사업을 널리 알려 투자를 촉진하고 에너지절감효과가 큰 설비 보급을 확대하는 좋은 계기가 될 것"이라고 말했다. 이번 행사에서 우수사례로 선정된 (주)에너지솔루션즈와 한국하니웰(주)의 ESCO투자사례를 살펴보자.

국가 에너지원의 다원화와 환경공해 저감은 정부의 저탄소 녹색성장 정책과 에너지 안보를 위해 달성해야만 하는 필수불가결한 과제로 자리 매김한지 오래이다. 또한, 화석연료의 환경문제 유발과 석유자원의 고갈위기 등으로 인해 이를 대체할 수 있는 신재생에너지 개발에 대한 관심이 고조되고 있으며 이러한 과제를 해결하기 위한 친환경 연료로써 DME(Dimethyl ether)에 대한 관심이 날로 증가하고 있는 추세이다. 특히 높은 세탄가를 지니고 물성이 LPG와 유사하여 디젤차량 및 LPG 대체 연료, 연료전지 등의 다양한 용도로 사용할 수 있고 수송 저장 수단, 인프라 구축 등의 장애가 적다는 장점이 있으며, LPG와 물리적 특성이 비슷해 기존 LPG 인프라를 개조하지 않고도 LPG와 혼합해 난방 및 취사뿐 아니라 차량 연료용으로도 시범사업이 활발히 추진되고 있는 상황이다. 그밖에도 액화상태로 저장 운송 등의 취급이 용이하다는 장점이 있다. 한국가스공사의 경제성 분석 결과, 본격 보급시 LPG대비 20~30% 저렴하게 공급가능하다고 판단되어짐에 따라 LPG사용자 부담을 완화할 수 있는 기대를 가지게 한다. 이에 우리협회는 지경부 한국가스공사등과 함께 프로판에 DME가 20%의 혼합된 DME혼합연료 소비자에게 보급하는 시범사업을 전개하고 있으며 현재까지 진행된 내용과 향후 계획등을 소개함으로써 DME에 대한 이해를 높이고자 한다.

Electric night storage heater was introduced and disseminated for power grid balancing and efficient management of power generation facility. But fuel cost for heating has been increased rapidly while the cost of electricity increased slightly. This abnormal rate system caused peak load in winter at last. To solve this problem, application of an air source heat pump was suggested. In the study, the effect of replacing night heater by heat pump and the economics were analysed. In addition the expectation of prospect of heat pump penetration was simulated based on surveyed and investigated data. As a result, fund supporting as well as institutional backing was needed for effective propagation and return of investment.

IT 업계에도 저탄소 녹색 성장을 추구하는 Green IT 시대가 찾아왔다. 이에 따라 여러 IT 기업들에서 IT 자원을 소유하지 않고 빌려 쓰는 형태의 클라우드 컴퓨팅이 큰 이슈가 되고 있다. 클라우드 컴퓨팅은 기존의 조직이 유지 보수에 사용하던 인력과 비용을 감소시킬 수 있다는 점에서 경제적 이익을 창출하고 있다. 그러나 다수의 이해당사자(Mlti-tenant)가 존재하는 공공 클라우드 환경에서는 사용자의 인증이 보안 문제로 대두되고 있다. 본 논문에서는 공공 클라우드 환경에서 신뢰할 수 있는 클라우드 서비스를 제공하기 위한 사용자 인증 방법을 제시한다. 사용자는 계약관계로 맺어진 클라우드와 조직사이에서 클라우드 서비스를 제공받으며 조직으로부터 인증 받는다. 클라우드에서는 조직에서 제공하는 인증 정보와 클라우드의 서비스 제공 정책으로 이루어진 보안연계를 통해 사용자를 확인함으로써 사용자에게 적합한 서비스를 제공한다.

2050탄소 중립 사회 전환을 위한 저탄소 발전전략으로 정부는 '2050 탄소중립'을 선언하고 '2050 탄소중립 시나리오' 수립을 추진하고 있다. 본 논문에서는 개인이 저(低) 탄소 생활을 위한 '에코라이프(녹색습관)' 탄소량 측정과 일상생활에서 자주 먹는 음식들의 탄소량을 측정함으로써 하루 얼마나 많은 양의 탄소 소비의 비교를 통해 경제와 지구를 살리는 '저(低) 탄소 에코라이프'를 제시하고자 한다.

On the crisis of international economy, the government is making an effort to seek economic growing motivation with the method of overcoming economic crisis and 'low carbon green growth'. Furthermore, to promote maritime vessel traffic service related inefficient energy wastage was revealed and eco-friendly alternative energy was accepted because of high price of oil in the beginning of 2008. In this situation, I'm going to discuss the possibility of eco-friendly energy system in maritime vessel traffic service with the way of cutting the budget and expansion of solar power generation system which was promoted to meet governmental 'energy saving plan for high price of oil'.

The purpose of this study is to improve the operation of shopping mall by examining the effect of service characteristics of Greenanum on customer satisfaction, repurchase and recommendation intention. The hypothesis was verified with SPSS22.0 and PROCESS macro 3.5. As a result, some hypotheses were supported between satisfaction, repurchase, and recommendation for service characteristics. Second, positive effects were found between satisfaction and repurchase, and recommendation intention. Third, a mediating effect appeared. Implications include improvement of low site awareness, benchmarking, and product quality improvement. In the future, it will be necessary to study the differences in the various characteristics of the products sold rather than the differentiation of the shopping mall itself.

Recently the technology of green growth became more important role among the problems of running out of fossil fuels and global warming. To procure a new growth power combined with energy and green growth, a lot of investment for wind power, photovoltaics system, fuel cell and biofuel expanded day by day. Among these, wing power has a merit of a highly economic and no discharge of toxic substance. These days government and industrial companies actively support the development of wind power technology with lots of investment, but domestic related education and equipment still stay in research level when it is compared with foreign advanced countries which lead the wind power technology. Therefore to expand the base of basic skill required in the related industrials and to advance technology, we are in the situation to be needed a development of a new curriculum and educational equipment which is analogous with the actual industrial system. In this paper a development of a new educational equipment for the learning of turbine control is introduced. This educational equipment has been developed for students to get easy understanding for the theory of wind turbine control. And finally to demonstrate the effect of the use of the developed equipments and curriculum a questionnaire carried out.

CEPA (Comprehensive Economic Partnership Agreement) between India and Korea may vitalize Korean economy more and more. Currently most of Korean firms have entered into manufacturing industries like electronics and automobiles. But only a few Korean companies are trying to penetrate into Indian green industry so this paper suggest how to enter into Indian green industry, especially renewable energy sectors. First, Exporting main shaft, tower-flange and polysilicon products can be considered, as a first step of entry mode. Second, entry mode based on contract like technology licensing, strategic alliance and joint venture establishment can be also one of options. For example, Korean solar energy industry which show more competitiveness than that of Indians should try to make technological licensing on PV modules. In addition to this, they should also try to make joint ventures with right Indian partners and build up 'Solar City' nearby regions like Gurgaon in India where many Korean firms are located. Korean shipbuilding firms like Hyundai Engineering which keep on developing wind turbo engines can also try to make strategic alliance with Indian firms like Suzlon which has strong competitiveness. After that, they should explore Korean and Indian wind sector markets together. Third, brownfield investment can be last and final option as a entry mode as we consider the peculiar characteristics of renewable energy industry. Lastly, Korean government which are rush to indulge into green business should formulate more proper and realistic policies to give big incentives the concerned firms which are trying to open international green market so government should make Korean green firms not to lose good market opportunities related to green industry like renewable energy sectors. Renewable energy sectors are basically regarded as infrastructures so close contact to Indian central government as well as state government will be also required.
