Abstract: In order to reasonably make good use of solar energy---a kind of typical and clean energy, especially increase the efficiency of solar energy usage in town buildings, this paper introduces and analyzes solar Thermal-arrest Technology by way of how to increase solar absorption efficiency and how to decrease collector heat loss, finds an effective way to increase the efficiency of present solar collectors. Solar Thermal-arrest Technology is good for being widely used in town buildings. Its reasonable development is helpful to reducing building energy consumption and the relief of present energy shortage in China.

Abstract: Taking one club as example, the application of the subtropical region ground source heat pump technology on indoor constant temperature swimming pool water heating load calculation and type selection of equipment is introduced. The system performance is analyzed through the experiment. The energy consumption cost of this technique is compared with electric boiler and oil-fired boiler, and the result shows ground source heat pump technique is superior and economic.

Abstract: This paper arranged as the logistic relations of the evolution history of the city and the reform of the energy technologies, Compared and analyzed the roles and the functions that the energy had played in the socialized process of the city. Point out that the explorations and applications of the new energy technologies will make the ‘Low Carbon Society’ reality, influence the words ‘City, make a better life’ deeply.

Abstract: Applying Toda and Yamamoto’s approach within a multivariate framework, this paper investigates the causal relationship between nuclear power consumption and real output. The results suggest suggest that there is presence of a positive significant Granger causality running from real output to nuclear power consumption, but there is no presence of a significant Granger causality running from nuclear power consumption to real output. The finding implies that nuclear power consumption doesn’t affect real output and policies assisting expansion of nuclear power consumption may not hinder real output, while policies promoting real output may boost nuclear power consumption.

Abstract: In the past five years, the development of wind power is always beyond expect, and keep the fastest growing energy status in the world. Considering the nuclear risk, government has suspended the audit of all the nuclear power project and conduct security clearance for the facilities of nuclear power. This situation provides wind power with broad developing prospects. In addition to its environment friendly, wind power industry also becomes necessary in economic development, and provides employment opportunities. This paper firstly presented the regional characteristics and season features of the wind energy resources in China and reviewed the national wind power development. This study provided some insights into the supply chain in wind power industry at present. Based on this, bottleneck of wind power development in China is discussed from the policy and technology aspects.

Abstract: Chinese Renewable energy Power Generation Construction (RPGC) is undergoing a rapid flourish nowadays, so a large amount of projects need to be contracted to engineer procure construct enterprises, namely EPC enterprises. However, high-level EPC enterprises always outsource specific activities to various vendors simultaneously, thus resulting in many outsourcing risks with regard to contract due to the underdeveloped Chinese RPGC outsourcing market mechanism. Based on the analysis of Chinese RPGC outsourcing market's features, an index evaluation system of vendor’s comprehensive ability is built up to help select the most suitable vendor, therefore reducing adverse choice risk. Moreover, with decrease of Chinese RPGC developing speed and gradual maturity of market, risks that EPC enterprises encounter will undoubtedly transmit and change, which are the risks requiring further research.

Abstract: The development of CdTe/CdS solar cells on flexible substrates is reviewed in this article. Photovoltaic structures on lightweight and flexible substrates have several advantages over the heavy glass based structures in both terrestrial and space applications. The cells mounted on flexible foil are not fragile, the requirements of the supporting structures are minimum and they can be wrapped onto any suitably oriented or curved structures. The specific power of the solar cells is an important factor in space applications and hence development of photovoltaic devices on light weight substrates is interesting. CdTe is one of the leading candidates for photovoltaic applications due to its optimum band gap for the efficient photo-conversion and robustness for industrial production with a variety of film preparation methods. Flexible solar cells with conversion efficiencies exceeding 11% have been developed on polyimide foils. The development of CdTe devices on metallic substrates is impeded due to the lack of a proper ohmic contact between CdTe and the substrate. The polymer substrate has the advantage that the devices can be prepared in both “superstrate” and “substrate” configurations.

Abstract: Al doped zinc oxide (AZO) as anode for bulk-heterojunction [regioregular of poly(3-hexylthiophene) (P3HT):(6,6)-phenyl C61 butyric acid methyl ester (PCBM)] organic solar cells was investigated. We got efficient flexible solar cells with a highly transparent and electrical conductive NiO film as hole-transporting layer (HTL) on optimized AZO substrate. The strcture of this kind of devices is PET/AZO/NiO/P3HT: PCBM /Al. The highest power conversion efficiency (PCE) on glass substrate is 3.15%, and 1.66% on flexible substrate. The physical and electrical properties of AZO thin film were discussed, and the device photovoltaic characteristics were investigated in detail.

Abstract: The traditional treatment methods of industrial residue are mainly landfill, compost and so on, but there are significant technical limitations. At present, with the continuous development of waste incineration technology, industrial residue incineration-power generation has become the new trend of international and domestic processing industrial residue, and achieved considerable benefits. This paper mainly introduces the current situation of waste incineration-power generation, as well as the superiority in the technology of environment and economy, and taking Shandong Chenmingxinli Thermoelectric Company Limited industrial residue reuse incineration-power generation project as an example, this paper elaborates the environmental, social and economic benefits achieved by the project. Therefore, enterprises should attach importance to the industrial waste recovery and recycling, easing the pressure on the environment, and the energy-saving reconstruct of production technology.

Abstract: Thermal design of building envelope and microclimatic conditions influence the indoor thermal comfort conditions and energy consumption of buildings. This paper presents the findings of study conducted to investigate the effect of building insulation on thermal impact and energy for cooling. The study were performed via computer simulation using a whole-building thermal energy software Integrated Environmental Solution (IES) with ApacheSim 5.9.2. The results show that pitch insulation (PITCH) was more effective to reduce the attic temperature but both pitch and wall insulation (WALL) had nominal thermal improvement for the indoor. However, compared to the BASE model, WALL model gave a significant savings of 41% for cooling
