Reasonable usage methods of energy resources, which are limited for human beings to use, consists of new & renewable energy (NRE) and demand side management (DSM). All technologies and policies for energy resources are classified into two fields, methods for using new energy resources and methods for using conventional fuel energy resources. Various development activities for these fileds have been implemented and various subsidy programs have been operated to penetrate into markets rapidly. These subsidy programs have various types of subsidy by energy resources and programs and the budget are funded by government, which is called Electric Power Industry Basis Fund and is managed considering technology level, economic analysis, global environment, etc. These subsidy programs are managed by Korea Energy Management Corporation (KEMCO) for NRE and by Korea Electric Power Corporation (KEPCO) for DSM, the management are different among two corporations because the purposes and features of establishment are different though these are all public organization. KEMCO is managing the NRE subsidy programs according to the government will, while the management of KEPCO subjects to power system operations though the government will for DSM is considered. NRE which is on the initial phase of diffusion would not affect on power system seriously but the affects could be grown when the diffusion and importance are expanded. Hence some integrated affection analyses considering NRE and DSM are required and this paper shows the concept of integrated operation strategies with ground source heat pump systems which are related with two fields simultaneously.

The photovoltaic (PV) industry, which occupies about 80% share of domestic new and renewable energy (NRE) sales, has played an important role in the development of the Korean NRE industry. This was made possible by the government's implementation of the 3rd Basic New and Renewable Energy Plan, which promoted strategic PV R&D, infrastructure building, and a variety of PV deployment programs. For instance, 'One Million Green Homes', 'Feed in Tariff', and 'Renewable Portfolio Standards' programs contributed greatly to the dissemination of PV systems in the country. Furthermore, these programs were supported with more than 380 billion Won over 6 year period (2007~2012). The strategic PV R&D contributed to the fast follow-up in commercial technologies. Because of the recent, sharp decline in PV prices caused by oversupply and economic crisis in European countries, both foreign and domestic PV companies are going through painful restructuring. Under these circumstances, the Korean PV industry needs to find a new strategy for making a breakthrough, and in this sense a proactive role of the Korean government is desperately needed.

This paper presents an adaptive strategy of GENCOs for reducing the greenhouse gas by fuel mix change. Fuel mix stands for generation capacity portfolio composed of different fuel resources. Currently, the generation sector of power industry in Korea is heavily dependent on fossil fuels, therefore it is required to change the fuel mix gradually into more eco-friendly way based on renewable energies. The generation costs of renewable energies are still expensive compared to fossil fueled resources. This is why the adaptive change is more preferred at current stage and this paper proposes an optimal strategy for capacity planning based on multiple environmental scenarios on the time horizon. This study used the computer program tool named GATE-PRO (Generation And Transmission Expansion PROgram), which is a mixed-integer non-linear program developed by Hongik university and Korea Energy Economics Institute. The simulations have been carried out with the priority allocation method in the program to determine the optimal mix of NRE(New Renewable Energy). Through this process, the result proposes an economic fuel mix under emission constraints compatible with the greenhouse gas mitigation policy of the United Nations.

Nowadays the concern about development and diffusion strategies of new & renewable energy (NRE) and its technologies are getting higher globally as Kyoto Protocol has taken effect this year and oil has been rising in price tremendously. Developed countries have already commenced the study and research for this problem and are looking for various solutions. In this paper, the support Priority of NRE technologies are determined by horizontal comparison analyses.

2008년 8월 우리나라는 온실효과로 인한 기후변화 대응 역량을 강화하고, 에너지의 안정적 공급과 효율화 체계를 구축하기 위한 방안으로 '제1차 국가에너지기본계획'을 발표하였다. 이에 따르면 우리나라는 세계 10위의 에너지다소비 국가이자, 그 중 97% 이상을 해외 수입에 의존하는 나라로서 신재생에너지설비의 중요성이 크게 부각되고 있다. 본 논문은 일반적인 건물의 난방설비로 이용되고 있는 가스와 유류설비를 지열히트펌프로 대체함으로서, 전력계통의 부하율을 향상시키는 방안을 제시하였으며, 이에 따른 에너지비용 절감과 온실가스의 감축방안을 정량적으로 제시하였다.

지구온난화 문제에 대한 대책으로 녹색 사업에 대한 관심과 투자가 높아지고 있다. 국내 건설 기업들도 기존 토목 및 건축 공종에서 신재생에너지 사업으로 영역을 확대해 나가고자 한다. 그러나 신재생에너지 사업은 투자경제성이 검증되지 않고 건설 기업들은 관련 리스크에 대해 명확히 인지하지 못하고 있다. 본 연구에서는 녹색 건설 사업의 일환으로 국내에서 수행되고 청정개발체제(CDM)사업으로 등록된 신재생에너지 사업의 투자경제성에 관한 단계별 분석을 수행하였다. 1단계에서는 UNFCCC에 등록된 국내 CDM 사업을 대상으로 분석을 수행하였으며, 그 결과 평균 IRR은 -3.19%로 사업들의 수익성이 저조한 것을 파악하였다. 2단계에서는 사업별(태양광, 풍력, 수력, 매립가스)로 IRR이 가장 낮은 사업을 선정하여 국내의 발전차액지원제도(FiT)와 탄소배출권(CER)판매를 통한 추가 수입을 적용하여 수익성 향상 여부를 정량적으로 분석하였다. 그 결과 투자경제성이 있는 사업은 매립 가스 및 풍력 사업이었으며 두 보조방안에도 불구하고 태양광 및 수력 사업은 수익성이 없었다. 또한 사업별로 보조방안의 비중이 상이한 것을 볼 수 있었는데 특히 FiT는 태양광, CER판매는 매립가스 사업이 가장 혜택을 보았다. 이에 비해 풍력 및 수력 사업은 보조방안으로 인한 추가 수입이 적은 것을 파악하였다. 4개의 대상 사업 중 매립가스의 IRR이 가장 개선되었으나 풍력사업이 NPV가 가장 높고 보조방안에 대한 의존도가 낮아 투자매력도가 좋은 사업으로 드러났다. 건설 기업들은 신재생에너지 관련 기술이 성숙하면서 경쟁력이 높아짐에 따라 장기적 관점에서 관련 사업에 투자와 경험을 구축하는 것이 중요할 것으로 판단된다.

Nowadays the concern about development and diffusion strategies of new & renewable energy and its technologies is getting higher globally as Kyoto Protocol has taken effect this year and oil has been rising in price tremendously. Developed countries have already commenced the study and research for this problem and are looking for various solutions. In this paper, R&D environments and diffusion status solar thermal energy in the United States are analyzed and the probability of application into Korea case is observed. To achieve this observation, correlations between US case and Korea case is estimated and the variation of duration and amounts in R&D and the R&D contribution to national economic growth are considered.
