풍력에너지 연구개발은 1970년대 에너지 위기 이후 시작되어 1980년대 초반까지 가격 경쟁력과 기술 부족으로 상용화에 이르지 못하였다. 그러나 1980년대 중반 미국을 시작으로 상업발전에 성공하여 100kW급 풍력발전시스템이 대량 보급되기 시작하였다. 1990대에는 덴마크, 독일, 스페인 등에서 대규모 풍력시장이 형성되었고, 2000년대 들어 대형화에 성공하여 기존 발전에 대한 시장경쟁력을 확보하게 되었다. 본 논문에서는 풍력에너지 보급 확산을 촉진하기 위해 풍력발전 시장의 동향분석과 함께 기술 특성을 분석하였으며 보급 촉진을 도모할 수 있는 확산 전략들을 제시하였다.

New & renewable energy technology development has been carrying out in 11 different areas so far. Many technologies are being applied to the required areas according to its own characteristics. Before launching the development, these technologies have been evaluated by their commercial effect and contribution to energy supply. In this paper, the impact factors enhancing the distribution of renewable energy were developed to select appropriate diffusion regulations for each technology area. In addition, AHP methodology was introduced to investigate priorities of the regulations along with weights of impact factors

AHP analysis was carried out to derive the optimum mix weight of hydrogen energy production material presented in a national vision of the hydrogen economy and the action plan and aimed to be commercialized by 2030{sim}2040 year. Six kinds of hydrogen production materials(natural gas, spare electric energy, fleeting gas, renewable energy, coal, nuclear energy) was selected as subjects of study and the perspective of optimum mix weight was derived through AHP analysis.

In this study, we studied solar cell and fuel cell. To estimate the technology competitiveness, we used patent analysis using patent information and delphi method. For patent analysis, PII indicating the impact of patent was used. Also to analysis PII, citations data of registered and published patent were used from 2001 through 2010 in the United States, Japan, South Korea and the European Patent Office. And the delphi method results of the 'International trend analysis on the Green Energy Technology and the establishment of international cooperation models(2009)' were cited to estimate the technology level. According to the analysis results, Korea's patent registration growth rate was fairly high, but the patent impact and technology levels were significantly lower than in the United States, Japan and Germany. Especially in the solar cell, United States's PII is 1.8, but Korea's PII is 0.2. And the technology level of United States is 7 to 8, but Korea's is 5 to 6. Therefore, to improve technology competitiveness, Korea need to enhance the core technology R&D, and set up the consumer-oriented R&D strategy for commercialization from R&D planning phase. In this study, we analysed competitiveness of renewable energy which is not actively discussed. But there are limitations of the study because we used the result of past research and patent data in the past 10 years. Therefore to accurate research the period of patent data should be extended. Finally diverse indicators for measuring the technology competitiveness should be researched and developed.

This paper analyses the economics of grid-connected photovoltaic systems. With the 2003 cost of photovoltaic systems, under prevailing capital market conditions, with a system lifetime of 30 years, and under the best climatic conditions, it appears that the cost of production of grid-connected electricity could be of 0.21 US /kWh, and under medium climatic conditions, European locations, Switzerland, Japan and South Korean could be of 0.28/kWh. If the lifetime if the system goes up, due to future technological improvements, to a very large value such as 50 years, these costs can be lowered by 10-20%. Competitiveness of grid-connected photovoltaic electricity, while it still cannot be taken for granted, is a possibility, especially if major technological advances further lowers the costs of photo cells and increases their lifetimes.
