Although renewable energy sources are more environmentally friendly than fossil energy sources, it is far more costly, considering current technological standards. It would not present many competitive advantages in the power market. If the renewable electricity is viable in the market, the government should take 'visible' actions to compensate production costs. Popular policies, such as Feed-In-Tariff and Renewable Portfolio Standards, can help to attract investors into generators of renewable electricity. But presently, they are mainly financed through a undifferentiated increase of electricity bills and occasionally confronted with the opposition of the electricity consumers. And most policies tend to focus on increasing the supply of renewable electricity with little consideration toward elevating the motivation of consumers. This study evaluates the potential of environmentally friendly energy consumption and examines the 'green pricing' program which realize the potential.

대표적인 신$\cdot$재생에너지의 시장확대 정책으로 RPS와 기준가격의무구매제가 주요 선진국에서 실시되고 있으며 자국의 자원부존과 경제사회여건에 맞춰 적합한 정책수단을 선택하고 있음. RPS 실시국가에서 RPS는 특별법으로 제정되어 실시효과를 극대화하고 있으며, 신$\cdot$재생에너지발전 인중서의 거래를 포함시켜 시너지효과를 거두고 있음. RPS의 단일의 최적모델은 존재하지 않으며 기본설계와 세부사항은 각 국의 고유의 자원부존 여건 및 경제사회적 특징에 따라 달라짐. RPS의 국내도입이 전력시장과 국민경제에 미치는 영향은 그리 크지 않으며 외부효과를 감하면 편익을 초래함. 또한 수요조사결과 RPS에 대한 선호도가 비교적 높게 나타나며 산$\cdot$ 재생에너지발전의 시장확대 수단으로 높은 점수를 매기고 있음 그러나 RPS의 기본설계를 신중히 가져가야 할 것이며, 법제도 정비에 임해서는 기존에 실시되고 있는 기준가격우선구매제도(발전차액보전)의 고려해야 함.

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.

While the policy intervention of each country for the promotion of renewable energy is strengthened, Korea introduced Feed-in Tariff (FIT) in 2002 to directly support the development of renewable energy. But in 2012, the shift of policy instrument that from FIT to Renewable Portfolio Standard (RPS) is occurred. This is a unique background that is currently found only in Korea, and new answers that focus on the outcomes of the shift of policy instruments are needed in addition to the existing discussion of comparison of FIT and RPS. Therefore, this study analyzed the change of policy efficiency after the shift to RPS using Data Envelopment Analysis(DEA) and Malmquist Index. In the result of analysis, a difference in the improvement of policy efficiency after in shift to RPS is found among each renewable energy source. This result is because renewable energy companies voluntarily entered the market only for energy sources that have secured technology or price competitiveness, and this indicates that the performance of renewable energy after the RPS shift has been concentrated on specific energy sources. As a result of this study, considering that the goal of renewable energy policy is to expand distribution and to drive growth engines, multi-faceted analysis is required in consideration of technology and market in selecting policy instruments.

Biomass is an abundant renewable energy resource that can replace fossil fuels for the reduction of greenhouse gas (GHG). Indonesia has a large number of cheap biomass feedstocks, such as reforestation (waste wood) and palm residues (empty fruit bunch or EFB). In general, raw biomass contains more than 20% moisture and lacks calorific value, energy density, grindability, and combustion efficiency. Those properties are not acceptable fuel attributes as the conditions currently stand. Recently, torrefaction facilities, especially in European countries, have been built to upgrade raw biomass to solid fuel with high quality. In Korea, there is no significant market for torrefied solid fuel (co-firing) made of biomass residues, and only the wood pellet market presently thrives (~ 2 million ton yr-1). However, increasing demand for an upgraded solid fuel exists. In Indonesia, torrefied woody residues as co-firing fuel are economically feasible under the governmental promotion of renewable energy such as in feed-in-tariff (FIT). EFB, one of the chief palm residues, could replace coal in cement kiln when the emission trading system (ETS) and clean development mechanism (CDM) system are implemented. However, technical issues such as slagging (alkali metal) and corrosion (chlorine) should be addressed to utilize torrefied EFB at a pulverized coal boiler.

Korean government set the goal of 5.6% to use renewable energy in electricity generation by 2011 compared with the current use of 0.13%. To achieve this goal, an innovative plan for market competitiveness would be required in addition to the feed-in-tariff [FIT] which is carried out at present in Korea. As a countermeasure, Ministry of Commerce, Industry and Energy [MOCIE] has taken it into consideration to introduce a Renewable Portfolio Standard [RPS] that is a purchase obligation program as an alternative plan to the FIT. Furthermore, the active renewable energy market may result from and also reversely result in the aid of North Korea with renewable energy. In this paper, we review The RPS in several country cases. Plans, systems, markets and institutionalization for solving efficiency in the area of renewable energy are discussed.

The photovoltaic(PV) industry has been growing around the PV advanced countries such as Japan, Germany, Europe and USA. In recent years, China became a strong performer in the world PV market share, increasing solar cell production rapidly The global photovoltaic (PV) market grew by over 40% in 2007, with approximately 2.3GW of newly installed capacity. The global cumulative installed capacity has reached 9GW. The cumulative installed power of PV system in Korea tremendously increased to 74.7MW at the end of 2007. Up to Sep. 2008 The cumulative installed power of PV system in Korea is approximately 377MW. The value chain of photovoltaic in Korea is creating actively. Thus Korea is predicted to see 800MW of modules installed in 2010. Korea's renewable energy is also targeting to take 5% of the total energy consumption by 2011.

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. However many PV systems are not installed in suitable part which is concerned about geometrical factor. It is generally recognized that the actual output of PV system in field is a function of orientation, tilt angle, irradiance, temperature, soiling and various system-related losses. Thus this paper shows that a experimental result of PV modules(A group) with uniform azimuth angle and PV modules(B group) with non-uniform azimuth angle. As a result, the electrical output of B group is decreased 48.8% as compared with electrical output of A group.
