  • 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.

  • The purpose of this paper is to derive priorities and implications for the organic resource conservation policy in the livestock sector. We conducted a survey on the importance-performance of the organic waste resource reclamation of livestock sector using a 5-point Likert scale. The importance average for the resource recycling of livestock organic waste was 3.63 and the average of performance was 3.04. As a result of the IPA on livestock manure recycling measures, it is necessary to improve feed quality, establish a local recycling system, increase demand for compost and liquid, enhance customer linkages, and develop cost reduction technologies. It requires intensive support for promoting the spread of odor reduction technologies and integrated management of biomass. It is necessary to introduce mid- and long-term measures such as the revival of feed in tariff, promote by-product feeding, establish solid fuel process management standards, create hygiene safety standards, develop eco-beads and promotion of feed conversion. It is required to strengthen support for the development of odor reduction technologies and prepare consultative organizations among related departments, develop eco-friendly solid fuel technology, and support policies for renewable energy certification.

  • In 2008, the global photovoltaic(PV) market reached 5.6GW and the cumulative PV power installed totalled almost 15GW compared to 9GW in 2007. Due to a favourable feed-in-tariff, Korea emerged in 2008 as the 4th largest PV market worldwide. PV power installation rose 495.5 percent to 268MW in 2008 compare to 45MW in 2007. Building integrated photovoltaic(BIPV) has the potential to become a major source of renewable energy in the urban environment. BIPV has significant influenced on the reflection by rear materials such as white back sheet and the heat transfer through the building envelope because of the change of the thermal resistance by adding or replacing the building elements. In this study, to use as suitable building materials into environmentally friendly house like green home, characteristic analysis of BIPV module according to rear materials achieved. Electrical output of PV module with white back sheet is high about 10% compared to other pv module because of 83% reflectivity of white back sheet compared to 8.4% reflectivity of other PV modules with different rear materials(black back sheet and glass). In the result of outdoor experiment during a year, electrical output of four different PV module is decreased about 3.72%.

  • The Korean government is planning to introduce the Renewable Portfolio Standard (RPS) system to replace the currently used Feed-in-Tariff (FIT) system which is a subsidy-based mechanism to foster the renewable energy industry. The RPS system is a market-oriented system in which the power companies are obliged to use renewable energy sources to produce electricity by a certain ratio of their production level. They can either produce for themselves or simply purchase the REC (renewable energy certificate) in the market to implement. The objective of this article is to compare the RPS system with the current FIT system in terms of the implementing cost to achieve the policy goal to expand the share of renewable energy m the total power generation. The analysis is conducted using Linear Programming models. The results of this study imply several policy suggestions to successfully introduce the RPS system.

  • Although renewable energy sources are more environmentally friendly than fossil energy sources, they are far more costly and hard to survive in the electricity market. For a competitive renewable electricity, the government should take 'visible' actions to compensate higher production costs. Popular policies, such as Feed-In-Tariff and Renewable Portfolio Standards, are financed by an undifferentiated increase of electricity bills (a collective financing mechanism) but are occasionally confronted with the opposition of the electricity consumers. This paper discusses the consumers' willingness to pay for renewable energy in order to back up the voluntary financing mechanism, the Green Pricing. The Tobit analysis of a consumer survey shows that the consumer's WTP is positively influenced by his environmentally friendly activities under both financing mechanisms. The knowledge on renewable energy is statistically significant only under collective financing mechanism.

  • Korea has been at the forefront of green growth initiatives. In 2008, the government declared the new vision toward 'low-carbon society and green growth'. The government subsidies and Feed-in Tariff (FIT) increased domestic usage of solar power by supplying photovoltaic housing and photovoltaic generation systems. Since 2000, solar power industry has been the world's fastest growing source with the annual growth rate of 52.5%. Especially, BIPV(Building Integrated Photovoltaic) systems are capturing a growing portion of the renewable energy market due to several reasons. BIPV consists of photovoltaic cells and modules integrated into the building envelope such as a roof or facades. By avoiding the cost of conventional materials, the incremental cost of photovoltaics is reduced and its life-cycle cost is improved. When it comes to atypical building, numerous problems occur because PV modules are flat, stationary, and have its orientation determined by building surface. However, previous studies mainly focused on improving installations of solar PV technologies on ground and rooftop photovoltaic array and developing prediction model to estimate the amount of produced electricity. Consequently, this paper discusses the problem during a planning and design stage of BIPV systems and suggests the method to select optimal design of the systems by applying the national strategy and economic policies. Furthermore, the paper aims to develop BIM tool based on the engineering knowledge from experts in order for non-specialists to design photovoltaic generation systems easily.

  • Recently, photovoltaic inverter is received attention in photovoltaic with introduction of feed-in tariff. However, this inverter has problems such as inability to respond flexible at climate change due to its opening, and decrease of efficiency and lifetime due to its abnormal operation. To solve the problem, we desire to develop the eco-inverter which has a temperature control to respond easily on the change of temperature, and use the sealed structure not to affect the environment. In addition, we derive the optimal position of cooling system which is placed inside of inverter to minimize the power consumption, and proposed the effective measure to improve the efficient of inverter by deciding the number of cooling system.

  • Korea also plans to introduce Renewable Portfolio Standard (RPS) for strengthening market functions after 2012 as United States and several members of EU countries did. Through the introduction of RPS, it requires energy industry to supply new and renewable energy at fixed rate. Therefore, it will contribute to the distribution of new and renewable energy. This paper analyzed the economic effect of the introduction of RPS using CGE. The summary of the paper on the analysis of the economic effect based on endogenous growth theory under imperfect market competition by using CGE is as follows; Since RPS possibly regulates the amount of new and renewable energy, it can achieve the target amount of new and renewable energy without fail. As achieving the target amount accurately, the distribution of more advanced skills can be expected. However, GDP reduction can occur because investment cost increases due to the requirement of new and renewable energy supply. Therefore, in the long run, it is appropriate to introduce RPS because it contributes to the distribution of new and renewable energy and can be utilized as a new growth engine to encourage economic growth.

  • 신 재생에너지 정책이 발전차액지원제도(Feed In Tariff; FIT)에서 신 재생에너지 의무할당제(Renewable Portfolio Standard; RPS)로 변화하면서 원별 경쟁이 가속화되고 있다. 태양광 산업 역시 이러한 환경 변화에 대처해야 하며, 그를 위한 정책 구성이 필요하다. 이에 태양광 산업 정책은 크게 두 부분으로 구분하여 진행해야 한다. 첫째, 폴리실리콘(Poly silicon)을 활용하는 다결정실리콘 태양광에너지에 초점을 맞춘 정책이며, 둘째, 미래에 상용화될 차세대 태양광 에너지에 대한 대비를 위한 연구 개발(R&D) 정책이다. 먼저 다결정실리콘 태양광에너지에 초점에서의 산업 정책은 산업육성정책과 수출정책, 인프라 구성 등으로 나눌 수 있다. 현재 과도한 국가부채로 인한 세계경제 악화로 태양광에너지 업체들의 경제성이 악화하고 있다. 더욱 빨리 그리드 패리티(Grid Parity)를 달성하기 위해 수직통합 등의 필요성이 대두하고 있다. 이에 본 연구는 그리드 패리티 달성시기를 위해 태양광 산업 내 세대 변화를 하는 경우와 하지 않는 경우를 비교하기 위해 고려할 요소를 분석하였다. 현재 신 재생에너지 가운데 태양광에너지는 타에너지원 대비 가격경쟁력을 갖추지 못한 상황이다. 그러나 수출을 고려했을 때의 향후 한국의 차세대 성장동력으로의 발전가능성이 존재한다. 따라서 가격경쟁력이 가장 중요한 영향을 미칠 신 재생에너지 의무할당제 정책 하에서 태양광에너지가 전혀 채택되지 않는 상황을 막기 위한 정책이 필요하다. 그를 위해 필요한 정책적 요소들을 알아보았다. 마지막으로 인프라 구성을 위해 태양광 산업의 가치사슬(Value Chain) 상에서의 기업 분포와 경쟁력에 대한 조사를 시행하였다. 이는 태양광 산업 내의 경쟁력을 갖춘 부문과 그렇지 못한 부문을 구별하기 위함이다. 미래에 상용화될 차세대 태양광 에너지를 준비하는 과정에서는 연구개발 관련 정책이 가장 중요하게 다뤄야 할 부분이며, 그를 위해 정부 차원에서 지원하고자 하는 기술로드맵 등에 대해서 정리하였다.

  • In line with the international community's movement to reduce greenhouse gas emission, Korea implemented FIT(Feed in Tariff) in 2002 as part of its renewable energy development project. Although the policy had shifted to full-scale RPS(Renewable Portfolio Standards) in 2012, policymakers are still seeking changes due to policy ineffectiveness. While previous studies explain sudden policy changes through external factors, recent research sheds light on internal factors in the process of policy transition. The purpose of this study is to investigate the factors that are responsible for rapidly changing policies in latecomer nations. In order to find this, we look at the case of transition from the FIT to the RPS in Korea's expansion of renewable energy policy. As a result of the research, it is confirmed that the Top-Down decision making system of Korea and the external regulatory change cause rapid policy transition. By looking at these variables, we propose useful implications for policymakers to minimize the policy failure in future policy design and evolution.
