Interest in renewable fuel of recent has increased. Among them, From next year the government announced that it would enforce the RFS. Interest associated with it are concentrated. The RFS, for manufacturers of transportation fuels such as a vehicle, you are a renewable fuel a certain percentage of the fuel supplied. In other words, it refers to a system of mandatory to supply by mixing biofuels. Already in Europe, America and other developed countries to diversify energy sources and subjected Additionally there since ancient times for its rural development by introducing the RFS takes effect coming. Further and inspect to deal with climate change, which is performed via the RFS. Some even are represented by five axis of the sustainability of the RFS.

Currently, the RPS(Renewable Portfolio Standard) is the policy which supplies new and renewable energy. Power generation companies with large capacity should produce renewable energy or secure through the purchase of REC (Renewable Energy Certificates) as mandatory. The government has revised the REC weight several times, which weights each energy source by evaluating the economic and social value of renewable energy sources, and revised the mandatory supply ratio to gradually increase. This study helps to find the impact of policies on related industries. In this study, time-series analysis and regression analysis on the capacity of PV(Photovoltaics) facilities as a dependent variable were performed to analyze the effect of the revision of the REC weight for photovoltaic power generation and the amount of mandatory supply for renewable energy. As a result, it was statistically assessed that the revision of the REC weight and the increase in the mandatory supply has a significant effect on the increase in the amount of PV facilities.

최근 정부에서는 우리나라 전 도서에 신재생에너지와 에너지저장장치(ESS)를 결합한 마이크로그리드 구축 사업을 계획하고 있기 때문에 이에 대한 연구가 활발히 진행되고 있다. 이때 분산전원 도입 시 부적절한 용량산정은 신재생 발전제한 혹은 전력공급부족 등을 유발하며, 이는 발전효율 저하 및 계통전력수급에 문제를 야기한다. 따라서 본 논문에서는 부하의 수요전력을 고려한 분산전원의 적절한 용량산정를 도출하기 위하여 제주특별자치도의 추자도를 실증사이트로 정하여 실제 부하패턴과 기상데이터를 가지고 신재생에너지원과 ESS의 용량별 신재생발전 출력 제한률을 분석하고자 한다. 출력 제한률은 MATLAB 프로그램을 통해 분석하였으며, 그 결과를 통해 추자도의 마이크로그리드화를 위한 분산전원의 적정용량을 나타내고자 한다.

With the prospect of an increasing shortage of energy resources, there has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards resolving the problems of extracting energy from the world's oceans, as they represent a vast potential source of renewable energy. This paper summarizes the extraction and conversion techniques of the ocean's energy resources, namely, energy derived from the ocean waves, tides, thermal gradients, and currents. For each energy extraction and conversion technique, case studies are discussed.

Korean government has been investing more than 400 billion KRW in R&D on renewable energy. This paper aims to measure the R&D efficiency of national R&D program in the field of renewable energy, and to identify the sources of inefficiency. 4,213 R&D projects supported by Korean government during 2009-2011 are analyzed by using Data Envelopment Analysis and statistical tests. Results implies as follows. First, hydrogen, bio, fuel cell, photovoltaic have higher R&D efficiency than other renewable energies. Second, universities conducted national R&D program more efficiently than firms did, and small and medium sized enterprises are more efficient than large sized enterprises. Third, R&D inefficiency is mainly caused by the lacks of patent performance rather than excessive R&D investment or academic paper performance.

Recently, the energy industry is implementing renewable energy supply policy to reduce energy consumption. The purpose of this study is to build a database that can help promote the supply of geothermal energy system to prepare for the increase of renewable energy demand and to develop a method to evaluate the possibility of geothermal energy system installation by using database information. The data used in the study was reliable using open data provided by national agencies. We obtained information necessary for the possibility of geothermal energy system installation, constructed a dedicated database, and studied the method of calculating the geothermal well capacity by using the database information. In the future, this study will establish a local environmental evaluation standard and add information on other renewable energy to contribute to the activation of renewable energy supply.
