신재생에너지산업의 발전은 에너지원의 문제를 해결하기 위한 필수적인 과제라 할 수 있다. 이에 따라 세계 각국에서 신재생에너지산업을 위해 적극적으로 움직이고 있다. 신재생에너지산업은 아직 산업기반이 약하고, 산업의 특성상 규모의 경제 및 기술개발을 위한 초기 투자가 필요한 경우가 많다. 따라서, 신재생에너지산업을 육성하기 위한 정책이 실행되고 있는데 우리나라 뿐만 아니라 많은 나라에서 대표적으로 실행하는 정책이 RPS와 FIT 정책이다. 신재생에너지산업은 다양한 이해관계와 경제, 사회, 환경, 국제 등의 변수를 동시에 가지고 있으므로 이를 종합적으로 고려한 정책이 필요하다. 신재생에너지산업의 경우 평가의 지표에 해당하는 부분이 많고 고려되어야 할 변수가 많으나, 이를 모두 고려하기 힘들고 고려한다 하더라도 일관된 기준이 마련되어 있지 않은 상황이다. 따라서, 본 연구에서는 신재생에너지정책을 평가하기 위한 평가지표를 개발, 제시한다.

독일은 환경 친화적이며 지구온난화현상에 직접적으로 영향을 미치는 이산화탄소 배출을 억제하는 방향으로 에너지정책을 실시하고 있다. 이를 기초로 환경 및 에너지 기술개발을 통한 지속가능한 성장정책을 실시하여 왔다. 따라서 독일의 에너지정책과 지속성장정책의 핵심을 이루는 요소는 재생에너지개발 보급제도, 생태적 에너지세, 배출권 거래제도 등이라고 할 수 있다. 특히 재생에너지 개발 및 보급을 통하여 화석연료 사용을 최소화하고 동시에 화석에너지 사용으로 인한 탄소배출비용을 지불하게 하는 탄소세 및 배출권거래 제도를 실시하여 재생에너지개발을 정책적으로 지원하고 있다. 본 논문은 재생에너지정책을 추진하면서 재생에너지 사용을 실질적으로 증가시키고 경제성장을 달성하여 환경에 미치는 부정적 영향을 최소화 하면서 지속가능한 발전이 현실적으로 가능한지에 대해 독일의 정책사례를 중심으로 한 조사 및 분석에 관한 연구이다. 실제로 경제성장을 위한 증가하는 에너지소비를 재생에너지로 대체할 수 있거나 경제성장을 달성하면서도 에너지소비가 증가하지 않는다면 환경에 부정적인 영향을 미치지 않고 지속가능한 성장을 달성할 수 있다. 이러한 전제조건을 충족시키는 모델사례가 독일의 에너지정책과 지속가능발전전략이며 이를 정책과 전략으로서 논리적으로 증명하는 것이 본 논문의 목적이다.

Temperature difference energy is a good energy source replacing the fossil fuels. In the study, we classified the temperature difference energy as 4 types by the source & using method. For the understanding economic property of temperature difference energy, we tried simle economic analysis. As the result, Pay back period of 4 case of the temperature difference energy are from 1.23 to 12.65 years. Major factors influenced economic effect are operation time and energy user distance from the temperature difference energy source. If we can select optimal capacity and look for more effient energy users, Temperature difference energy play a important role of replacing fossil energy. So, for dess emination of temperature difference energy, we suggest that temperature difference energy must be included in renewable energy. Applying the effective methods among various promotion program of renewable energy policy, utilization of temperature difference energy could be activated.

This study is to propose the quantitative methods instead of total results on New & Renewable energy R&D investments. To do that, this study used KETEP R&D investment profile, National R&D investment profile, and ISTANS industrial census results. From the analysis, this study firstly showed that the R&D investment on New&Renewable energy is higher than that of other industrial parts. And the investment increase ratio on New&Renewable energy is also very higher during past 10 years. And finally showed that the ripple effects(relatively the employee number, the amount of sales, and the amount of export) of the focus energy group including feul cell, photovoltaic, and wind power was higher than those of general manufacturing industry. This approach was firstly conducted using the poor census results, so other analysis methods will be developed and performed to exact;y show the investment ripple effect.

This study compared and analyzed major policies and operational processes of countries that introduced the Renewable Energy Plan Site, through literature analysis of published governmet data, and previous research results. The procedures of the Renewable Energy Plan Site were classified into planned location designations, selection of power generation business operators, designation of the business' district and development and evaluating the factors derived for each procedure. Four contries were selected to be compared and analyzed, namely: Denmark, Germany, the United Kingdom and Japan. This was based on the criteria used to introduce and operate the Renewable Energy Plan Site, activate renewable energy supply and check the applicability of Korea's policies. It was analyzed that the priority of the planned location for the procedure was different for each country depending on the conditions there.

Setback regulations stand out as a primary hindrance to the widespread adoption of renewable energy in South Korea. This study analyzed the current status of domestic and international setback regulations, laying the groundwork for an in-depth discussion aimed at improving regulations related to solar photovoltaic setback distances. While setback regulations lack universal standardization across nations, regulations in the United States exhibit certain similarities to those implemented in South Korea. Notably, South Korea has seen a gradual tightening of regulations from 2018 to the present, implementing standards approximately 5 to 10 times stricter than those in the United States.

The assessment of the potential for the design of marine renewable energy systems is reviewed and the current situation for marine renewable energy is promising. The most studied forms of marine renewable energy are ocean wind energy, ocean wave energy and tidal energy. Wind turbine generators include mostly horizontal axis type and vertical axis type. But also more exotic ideas such as a kite design. Wave energy devices consist of designs converting wave oscillations in electric power via a power take off equipment. Such equipment can take multiple forms to be more efficient. Nevertheless, the technology alone cannot be the only step towards marine renewable energy. Many other steps must be overcome: policy, environment, manpower as well as consumption habits. After reviewing the current conditions of marine renewable energy development, the authors analyzed the key factors for developing a strong marine renewable energy industry and pointed out the huge potential of marine renewable energy.

With the opening of the small power brokerage business market in December 2018, the small power trading market has started in Korea. Operators must submit the day-ahead estimates of power output and receive incentives based on its accuracy. Therefore, the accuracy of power generation forecasts is directly affects profits of the operators. The forecasting process for power generation can be divided into two procedure. The first is to forecast solar irradiation and the second is to transform forecasted solar irradiation into power generation. There are two methods for transformation. One is to simulate with physical model, and another is to use regression model. In this study, we found the best-fit regression model by analyzing hourly data of PV output and solar irradiation data during three years for 242 PV plants in Korea. The best model was not a linear model, but a sigmoidal model and specifically a Gompertz model. The combined linear regression and Gompertz curve was proposed because a the curve has non-zero y-intercept. As the result, R² and RMSE between observed data and the curve was significantly reduced.

This study investigated the reference case in the UK where legality and sustainability were systematically established for forest biomass represented by wood pellets. The UK is the country that best utilizes the trade value of wood pellets based on sustainability, with bioenergy accounting for 31% of total renewable energy production. The UK imported wood pellet, estimated 8,697 thousand tons in 2019. The UK government has continuously improved the renewable generation policy system to ensure the sustainability of wood pellets. The weighted average greenhouse gas emissions of a UK biomass power plant that received a Renewable Obligation Certificate (ROC) in 2018-19 was 26.71 gCO2e/MJ. These power plants are expected to meet the upper limit of 72.2 gCO2e/MJ by 2025. To issue an ROC, the biomass power plant must demonstrate that 70% of its total biofuel usage is sustainable. The UK uses the Sustainable Biomass Program (SBP) certification system, which is gradually expanding to other European countries, to prove the sustainability of biomass energy fuels. Global wood pellet production with SBP certification in 2019 was 10.5 Mt. This trend has significant implications for introducing additional sustainability into the wood pellet policy of South Korea.
