This paper conducted an analysis of economic effects of offshore wind power in Korea with benefit/cost analysis. The existing feed-on tariff, which was too low to support wind power development, was recently replaced with a Renewable Portfolio Standard(RPS), effective from 2012. According to the new regulatory policy, The Korean government has announced a strategy to draw investments worth for offshore wind farms with a total capacity of 2.5 GW over the next eight years, which is expected the change of cost and benefit. After overview the offshore wind power development status, The effects on cost can be divided by economic, environmental and social factors. Each factor will be calculated and combined by both evaluating index and using Quantification methods. At the end, the implication for the evaluation of feasibility of offshore wind power of Korea will be done.

가축의 사료로서 오염 농작물의 이용에 대한 최적기간 결정 방법론을 비용-편익 분석법에 근거하여 모델링하였다. 많은 농작물의 왕성한 성장시기인 8월 15일을 방사성물질의 침적시점 (사고시점)으로 가정하여 잡식성 가축인 돼지에 대해 적용한 결과를 논의하였다. 또한 사료로서 오염 농작물의 이용에 대한 상대적 비용 효과를 고찰하기 위해 오염 농작물을 바로 폐기시켰을 경우와 순이득을 비교 논의하였다. 침적후 농작물내 방사성물질의 농도는 동적섭식경로모델 DYNACON으로부터 예측되었다. 대응행위에 의한 순이득은 피폭선량의 금전가와 수행에 소요되는 금전적 비용에 의해 정량적으로 평가하였다. 오염 농작물을 사료로 이용함에 대한 순이득은 핵종, 농작물의 공급분율, 공급기간 등에 따라 다양하게 나타났다. 사료로서 오염 농작물의 이용은 $^{137}Cs$ 침적에 비해 $^{90}Sr$ 또는 $^{131}I$ 침적의 경우에 비용측면에서 보다 효과적이었다.

Gas hydrates draw great at tent ion recently as a new clean energy resources substituting conventional oil and gas hydrate its presumed huge amount of volume reaching 10 trillion tons of gas and environmentally friendly characteristics. Gas hydrate can contribute to the rapidly increasing consumption of natural gas in Korea and achieve the self support target by 2010 which is $30\%$ of total natural gas demand. This paper shows the importance and benefit of Gas hydrate comparing with new & renewable energy in Korea

his paper develops the systematic and quantitative priority-determining method for national investment using the framework of evaluating R&D. This study proposes multi criteria for evaluating the R&D of New & Renewable Energy through analysing the attribute of 11 types of energy. The framework is constituted by 4 criteria, the political urgency, economic impact, regional constraint. and technological attribute and the each criteria has 3 or 4 sub-criteria. These sub-criteria are weighted using AHP.

This paper aims to design a policy-assessment tool liking the Environmental Impact Assessment(EIA) and the Cost Benefit Analysis (CBA). As a step towards the incorporation of environmental and economic considerations, the approach used herein takes the form of integrating quantitative information on environmental benefits and costs associated with implementing the project into the existing framework of the EIA. Our case study is an project appraisal of a solar energy plant. It is confirmed that the technique is operational, however, there are certain limitations for a complete assessment. The difficulty mainly originated from the omission of important information from each step of the valuation process. Alternatively stated, some environmental services are not identified, nor quantified, and nor monetized in the process. More case studies are warranted in the future along with elaboration in methodology of techniques. In addition, the construction of a database on environmental values will be required to accumulate reliable and systematized data. These are the necessary conditions to improving quality in application of techniques as well as providing comprehensive and balanced information to decision makers.

Purpose - This study aims to analyzing of solar power generation cost-benefit. Design/methodology/approach - We analyzed whether there is economic feasibility by selecting parking lots and idle sites located in four areas of Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang areas nationwide, and analyzing site conditions and installation capacity. Findings - According to the results of the analysis, it was found that there is low profitability in Seoul, Gyeonggi and Chungcheong regions, where the solar radiation was not excellent even if REC is selected through the contract market. However, it is necessary to analyzed the economical validity the profitable validity including environmental benefits (greenhouse gas reduction, NOx, SOx reduction effect) and social benefits (renewable power supply) that is analyzed by income and operating costs which is occurred from electricity sales and REC sales when installing solar power generation facilities. Research implications or Originality - In this study, economic feasibility was evaluated additionally in consideration of environmental and social benefits. In conclusion, it was shown that businesses are not economical when considering only simple financial aspects are also sufficiently economical when it is considering environmental and social benefits.

This paper proposes the cost analysis on the energy efficient equipment when this equipment is participated in the demand-side bidding. Conventional demand-side bidding is exercised through load re-distribution. However if this load reduction is exercised by the use of high efficient equipment, its effect will be assumed to be more economical. This paper analyses this cost-benefit effect of high efficient equipment in the demand-side bidding.

This study analyzes the economic feasibility of agrivoltaics in South Korea. The key findings are as follows. It was ascertained that an amendment to the Farmland Act, which currently has an 8-year permit period, is necessary to ensure the economic feasibility of agrivoltaic projects. Furthermore, economic feasibility improves when agrivoltaic projects are financed, as against cases without financing. Furthermore, the availability of low-interest loans through financial support programs significantly enhances economic feasibility. Scaling up projects leads to cost savings due to economies of scale, while community-based agrivoltaic initiatives generate higher revenue through the acquisition of additional Renewable Energy Certificates. These factors can help improve the economic feasibility of agrivoltaic projects. These incentives are emphasized as they can serve as a source of funding to foster community acceptance of agrivoltaic projects.

에너지 IT 사업을 보다 효율적으로 수행하기 위해서 뿐만 아니라 전력선 통신망을 기반으로 한 서비스 구현을 효과적으로 추진하기 위해 제시되는 개념이 HSA(Home Service Aggregator)이다. 전력선 통신망 기반의 HSA 사업 모델 개발은 새로운 에너지 분야 사업 영역의 확대와 소비자 중심의 서비스를 통한 신수요 창출의 기회를 제공할 것으로 기대를 모으기에 충분하다고 할 수 있다. 따라서 본 연구에서는 보다 효율적이고 성공적인 HSA사업 모델 개발을 위해 가장 우선적으로 행해져야할 경제성 평가를 에너지 사업자 입장에서 면밀히 분석해 정책 의사 결정에 도움을 주고자 하였다. 분석을 위한 기본 데이터 수집을 위해 총 사업 기간은 2009년도부터 2020년까지로 하였으며, HSA사업 비용의 범위로 장비 비용, 장비 설치 비용, 그리고 운영비용으로 나누어 살펴보았다. 이중 장비 비용 및 장비 설치비용은 MGW와 RMS에 대한 것이고, 운영비용은 인건비, 회선운용비 및 설비 유지 비용으로 구성하였다. 그리고, 투자 대상의 범위는 주거 밀도가 높은 도심지를 대상으로 한 약 900만 수용가로 삼았다. HSA사업을 통해서 얻을 수 있는 중요 편익 원천으로는 원격검침서비스(AMR : Automatic Meter Reading), 인터넷통합빌링 서비스, 통합과금서비스, 인터넷 서비스, 그리고 방범 서비스에 대한 편익을 분석 범주로 설정하여 경제성 평가를 수행하였다. 그리고 전기 안전 편익은 사회적 편익으로 별도로 살펴보아 HSA사업의 정책 결정에 도움을 주고자 하였다. 연구 분석 방법론으로써는 경제성평가 방법론 중 가장 많이 쓰이고 있는 현금흐름할인법을 활용한 순현재가치법을 이용하였다. 연구결과 HSA 사업의 총 투자비는 1조 400여억원으로 산출되었고, 사회적편익을 제외한 총편익은 1조 20여억원이 산출되었다고 2015년까지 투자비를 회수한다고 가정하였을때 각가구로부터 얻어야 할 편익은 월간 가구당 513원으로 분석되었다. HSA의 사업에 대한 ROI는 1에 약간 못미치는 0.954값이 나왔으나, 사회편익 요소인 전기안전 편익이 크기에 이를 모두 편익에 포함한다면 HSA사업의 경제성은 1을 넘게 됨을 확인할 수 있었다.

The unequivocal risk of climate change, the weakness of energy security, and the problem of air quality will be possibly accelerated by the same reason, the enhanced fossil fuel dependancy in the future. It is obvious that greenhouse gases and air pollutants are mainly emitted from same sources. Moreover, greenhouse gases and air pollutants have their adversed impacts on same socio-economical, and environmental sectors. With these regards, several but limited studies have emphasized on the importance of the integrated management of climate change and air quality problem. In this study, we address the current trend of energy consumption and the change of air quality condition. Also the related policies are checked out in order to reduce emissions of greenhouse gases and air pollutants in Korea. By surveying previous studies, it is shown that the cost of climate change actions can be reduced by air quality co-benefits and vis-a-versa. Also the integrated strategy for climate change and air quality is introduced in term of cost-effectiveness and co-benefit.
