  • The reclaimed land has peculiar characteristic of nature environment unlike midtown or inland and also, in comparison with inland, has bad weather condition, such as low temperature, strong wind, excessive sunshine, and moisture involved in a salt. Therefore the case of developing water front needs understanding characteristic of weather environment mused by reclamation in detail and proper development and organized maintenance. If development which doesn't investigate topographic and climate characteristic sufficiently is drove ahead, a rise of expense for energy and maintenance is going to be mused by deteriorating weather environmental, occurring a flaw of facility and calculating inaccurate capacity of facility. We looked into the weather state and drew up the standard weather data of the newport area in Busan which is reclaiming and developing now. In this research at the base qf the standard weather data, we calculate the dynamic peak loads for commerce, business and residence and then we utilize the results of the load calculation as basic information to determine facility capacity in the rear city of the newport area.

  • Space Layout has been an issue in the facet of reducing the co2 in that the transportation sector has been to represent almost more than 20% of the total energy consumption for decades. Beside the development of the more efficient transportation systems, an efficient space layout makes it possible to reduce the amount of energy consumption in the transportation sector through allocating the sub-spaces in such an arrangement of minimizing the travel distances. In line with this thinking, this research aims at implementing a simulator which can calculate the vehicle-based travel distance upon a certain space layout. Based on the findings that the vehicle-based travels take place between the two functionally related sub-spaces, this research addresses a method of calculating the vehicle-based travel distance by multiplying the traffic volume of each sub-spaces by the travel distance to the other connected sub-spaces.

  • This paper presents a GIS-based site suitability analysis for a smart hydrogen energy plant in the Gangwon-Do region, South Korea. A GIS-based multi-criteria decision analysis (MCDA) was implemented in this study to identify the most suitable sites for the development of smart hydrogen energy plants. The study utilizes various spatial data layers, including hydrogen generation potential and climatic conditions, environmental and topographic conditions, and natural catastrophic conditions, to evaluate the suitability of potential sites for the hydrogen energy plant. The spatial data layers were then used to rank and prioritize the sites based on suitability. The findings revealed that 4.26% of the study area, or 712.14 km2, was suitable for constructing smart hydrogen energy plants. Some regions of Cheorwon-gun, Chuncheon-si, Wonju-si, Yanggu-gun, Gangneung-si, Hoengseong-gun, and near the coastal region along the east coast were found to be suitable for solar and wind energy utilization. The proposed MCDA provides a valuable tool for decision-makers and stakeholders to make informed decisions on the location of smart hydrogen energy plants and supports the transition to a sustainable and low-carbon energy system. Decision-makers can use the results of this study to select suitable sites for constructing smart hydrogen energy plants.

  • 신재생에너지의 한 분야인 소수력발전은 지형이나 기후 등 자연적인 조건과 조화를 이루며 국내 부존 잠재량이 많아 보급효과가 큰 것으로 평가되고 있다. 국내의 소수력 발전 부존량은 1,500MW 정도로 알려져 있으며 시장잠재량은 2030년까지 660MW로 예측되고 있다. 국내 부존량을 모두 개발하면 연간 70만M쪼, 약 700억원 규모인 것으로 예상되고 있다. 정부는 오는 2011년까지 소수력발전 보급목표량을 80MW로 정해 소수력발전 보급을 추진하고 있다. 최근 정부의 신재생에너지 보급정책에 따른 지역에너지 보급사업, 신재생에너지 의무공급제도(RPS)와 발전차액지원제도로 소수력 개발의 필요성이 증대되면서 공공기관에서 소규모 소수력 개발이 활발하게 추진되고 있지만 본격적인 상용화에는 한계가 많다는 지적이다. 소수력 발전의 전체 시장 매출은 매년 비슷하지만 정부의 정책적 지원 및 관련 기술개발, 인허가 절차의 획기적 개선 등을 통해 국내의 풍부한 부존량을 개발하면 새로운 시장이 열릴 것으로 전망된다. 특히 세계 최고의 소수력 보급 국가인 중국의 경우 앞으로도 지속적으로 소수력 발전소를 개발할 계획이어서 해외진출에 관심 있는 설비건설 업체라면 중국 시장을 노크해볼만 하다는 게 전문가들의 의견이다. 이번 호에서는 소수력 발전 기술 및 동향과 시공사례를 살펴보고자 한다.

  • 최근 지방자치단체에서는 농업용 취수보를 이용한 소수력발전에 관심을 가지고 지자체내의 유휴자원인 하천유수를 이용하여 소수력발전을 함으로써 환경친화적인 에너지를 생산하여 석유 등 에너지 수입대체 효과와 전력수요 급증시의 부하평준화에 기여하고자 하고 있다. 이는 정부의 "저탄소 녹색성장의 에너지정책"에 부응하는 것이며, 또한 하천에 소규모 인공호수를 조성함으로써 소수력발전소 인근지역의 경관개선과 관광자원화에 기여함은 물론 농업용수 공급과 하천유지수를 조정하여 안전한 하천으로서 그 기능을 하도록 계획한 것이다. 이와 병행하여 소수력발전소에서 발생한 무공해 청정에너지를 생산함으로써 전 세계적으로 관심이 높아지고 있는 '온실가스 배출 감축' 노력에 동참함으로써 선진형 기후변화 대응체계에 적응할 수 있다. 본 연구에서는 농업용 취수보를 대상으로 소수력 발전시설의 성능분석 기법을 이용하여 소수력발전시설적용 타당성을 조사 분석하였다. 그림 1은 농업용 취수보인 북평보의 유역면적도를 나타내고, 그림 2는 북평보에 소수력발전시설을 적용할 경우의 부하특성을 나타낸다.

  • The goal of impact studies (e.g., as mandated by NEPA in the USA) is to ensure that the full implications of development proposals (ecologic, economic, and social) are taken into account before decisions are made and projects are allowed to proceed. In other words, the aim is to ensure that impact assessment is integrated into planning and policy processes. Today. nearly 25 years after the enactment of NEPA, it is appropriate to inquire regarding the extent of progress toward such integration. This paper examines the role of impact assessment in planning and policy processes with specific reference to resource development projects in the Great Plains region of the USA. The author gives special attention to the socioeconomic impacts associated with energy resource extraction and conversion projects and the role of impact assessment in project evaluation, in local and regional planning, and in state policy development.

  • Research and development works on practical application of natural energy utilization systems involving solar, wind and sea wave energies are under promoting for the purpose of improving the energy consumption structure. These natural energies, made available with the use of relatively simple apparatus, are clean economically efficient and highly effective in the conservation of environment. However, these natural energies also have low energy density, randomness and regional variations. To compensate for these characteristics, hybrid utilization of solar and wind energies is currently under study. The introduction of a plural number of the natural energy hybrid utilization systems into a specific area will affect the economic efficiency, reliability and environmental conservation. Evaluation method of such effects has been examined in this study. The present method consisted of the steps described below. First, available energy was calculated from insolation distribution and wind velocity distribution in the specified area, and then the effect on the configuration of the power system load was obtained. This was followed by the determination of the optimal power dispatch over the specified period and by evaluations in light of economic efficiency, reliability and environmental indices.

  • Living in the modern age with well-developed scientific technologies, all of us are enjoying convenient lives because of 'energy'. Korea, poor in resources, is importing a large portion of its energy sources from abroad but energy consumption shows an upward tendency due to the continuing economic growth and the improvement of living conditions. The atomic energy is considered a self-reliant, alternative energy source like our country. However, it is necessary to educate the people on and publicize atomic power generation in the face of the widespread negative recognition that the atomic power plant is a hazardous facility. The study approaches to these matters with a human-friendly and environment-friendly coloring plan in the perspective of environment coloring plan. The study aims to minimize negative images of the atomic power, while highlighting its friendly and positive images so as to enhance the confidence of the people on the atomic power and to create a clean image for the atomic power. For this goal, the study examined and analyzed cases of Japanese nuclear power plants and domestic nuclear power plants, and also carried out an on-site survey in the sites in which nuclear power plants would be constructed to extract concrete colors through the analyses of their natural environment and actual conditions. The study also carried out a survey of residents in the regions to induce their participation, and reflected the survey results to the coloring plan. The study is expected to create a stable and friendly image of the nuclear power plant through materializing its environment-friendly image and remove negative recognition that the people have on the nuclear power plant. It also attempted an external environment-coloring plan a s a strategic means for positive publicity and through this, is expected to ultimately contribute to the creation of the new images of nuclear ower plants.
