| Summary/Abstract |
Distributed energy (DE) is receiving lots of attention from the Chinese government. A number of DE projects have been constructed in China. However, there are still numerous problems with DE projects. What hinders the development of DE in China? The Huadian Jimei distributed energy project (HJDE) is a typical DE building project that was not completed successfully. This paper focuses on this DE project to explore the barriers to DE development. The research group conducted 13 semi-structured interviews with representatives of institutions and corporations involved in the HJDE project to collect information. Based on the information, three types of problems were determined, and the results indicate that these conflicts between the core stakeholders make DE projects unsuccessful. These problems result from institutional barriers to DE, rooting in the development policy and the current energy market. Moreover, several key stakeholders are not able to play an active role in the design or management of DE projects. The Chinese government will put a much greater effort into the development of future DE projects. Many national support policies and rules will be announced, which are easy to practical use. Under these conditions, 1000 DE projects will be successfully completed until 2015.

| Summary/Abstract |
Spatial variation of solar energy is crucial for the estimation of the regional potential and selection of construction location. This paper presents a case study of using high resolution grid map of solar radiation combined with the other restriction factors to evaluate the comprehensive potential analysis of solar PV generation at the regional scale, in order to present a framework of decision support tool for solar energy management in a regional area. The cost of PV generation is calculated based on the geographical distribution of technical potential. Moreover, geospatial supply curve (GSC) is employed to portray the evolution of available potential of photovoltaics (PV) generation with the increase of the generation cost. By integrating the economic evaluation variables of net present value and simple payback period, grid-based economic feasibility of PV generation project is then carried out under two feed-in-tariff scenarios. Finally, total CO2 reduction potential and its spatial distribution in the study area are calculated. The results confirm that PV technology provides high potential for roof-top application and large-scale PV stations. Additionally, determining a reasonable feed-in tariff is essential for expanding the application of solar PV energy. The findings improve understanding of regional renewable energy strategies and the supply/demand assessment.

| Summary/Abstract |
Following the announcement of the China's 2020 national target for the reduction of the intensity of carbon dioxide emissions per unit of GDP by 40-45% compared with 2005 levels, Chinese provincial governments prepared to restructure provincial energy policy and plan their contribution to realizing the State reduction target.
Focusing on Fujian and Anhui provinces as case studies, this paper reviews two contrasting policies as a means for meeting the national reduction target. That of the coastal province of Fujian proposes to do so largely through the development of nuclear power, whilst the coal-rich province of Anhui proposes to do so through its energy consumption rate rising at a lower rate than that of the rise in GDP. In both cases renewable energy makes up a small proportion of their proposed 2020 energy structures. The conclusion discusses in depth concerns about nuclear power policy, energy efficiency, energy consumption strategy and problems in developing renewable energy.
