自改革開放後經濟發展突飛猛進的中國，面臨傳統化石能源日益短缺以及環境生態污染轉趨嚴重，不僅需承受減排溫室氣體之國際壓力。能源、環境與經濟三者間之矛盾，更將嚴重制約其經濟與社會之發展。是故，藉由開發再生能源確保能源安全，以維持經濟穩健成長、緩解潛在之能源危機及有效保護環境生態已是中國的必然選擇。本文係針對2005 年《可再生能源法》及2010 年新版《可再生能源法》作初步分析。闡述本法所建立的總量目標制度、強制上網制度、分類電價制度、費用分攤制度及專項資金制度作整體性之淺介；並就修正前後所造成的制度性差異，作一評析。本文希望能拋磚引玉，藉由本文之研究成果提供政府於未來推動與擬訂綠色能源政策或法制措施之參考。 Along with the further progress of the China’s reform and opening-up, this not only brings economical value for China, but it also makes China to face growing shortage of traditional fossil energy sources. The environmental pollution of China also becomes increasingly serious. Moreover, it has to take the international pressure of reducing greenhouse gas emissions. China has to ensure energy security, in order to maintain the steady economic development, to alleviate the potential of the energy crisis, and to protect the environment effectively. This article focuses on the analysis of 2005 “Renewable Energy Law” and the 2010 version of “Renewable Energy Law”. It gives overall analysis of the Renewable Energy Target Policy, Feed-in Law, Classified Electricity Price Regulation, the Cost Allocation Policy, and the Special Funds Institution; it also describes and assesses the system differences before amending the act. This paper hopes the study results of this article can provide references for the government to promote and develop green energy policy or legal measures in the future.

Paraffin phase change composite material (PPCCM) has attracted increasing attention and research from scholars at home and abroad because of its excellent latent heat value and high energy storage density. As an important class of medium and low temperature phase change materials, PPCCM is the first choice to prepare room temperature and low-temperature composite phase change materials. However, the risk of low thermal conductivity and some defects are obstacles for the industrialization of PPCCM. Due to the unique structure of carbon nanotubes (CNTs) with complex coils and excellent thermal conductivity, CNTs is considered as one of the important candidate materials that are expected to improve the thermal performance of PPCCM significantly. Therefore, the combination of CNTs and paraffin has become a hot issue. In this review, according to the current research status of CNTs and PPCCM in the past few years, the preparation, microencapsulation and practical application were systematically summarized. The challenges(complex preparation process, poor stability, few actual evaluation, etc.) and possible research priorities(doping ratio, wettability, economy, etc.) were also discussed.

Based on the energy storage problems for solar energy utilization and the advantages of spiral groove tube heat exchanger, spiral groove tubes are used in the solar energy phase change heat storage, with numerical simulation of the thermal storage process of heat reservoir. Firstly, the simulation method and the reliability of the used model are verified experimentally with smooth tube. Using spiral groove tube as water flow pipe and phase change material as heat storage medium, building the three-dimensional model by Gambit software and meshing by ICEM, the heat storage process in the spiral groove tube and smooth tube heat storage are numerically simulated while the heat transfer enhancing effect is investigated. The influence of structural parameters such as groove pitch and groove depth on the heat storage process is simulated numerically and the influence rules are analyzed. The results show that the convective heat transfer intensity and heat transfer capability are enhanced when the smooth tubes are substituted by spiral groove tubes in the phase change heat storage and the heat storage time become shorter. In the range of simulation, the optimal structural parameters of spiral groove tube is that the groove pitch p=7 mm and groove depth e=0.4 mm. The further improved design of phase change thermal storage can be realized in later research in-depth.

This work studies the effective multicast of data from base station to multiple devices in a small area, and proposes a fixed-relay based multicast scheme and a dynamic-relay based multicast scheme. Furthermore, aiming to minimize the total energy consumption of all devices, this work analyzes and obtains the optimum relay and its transmit power. Compared to the traditional multicast scheme, the proposed two schemes greatly reduce the total energy consumption in a multicast cluster.

Vegetation phenology is one of the sensitive indicators reflecting global climate change and vegetation growth. Inner Mongolia is an important ecological security barrier in the north of China, and a key area for resource development, environmental protection and ecological security in China. Studying its vegetation phenological changes can know its vegetation growth status, which is of great significance for understanding the characteristics of climate change and extreme climate events in the region. Based on the normalized differential vegetation index (NDVI) data product in MOD13Q1 product, this study use Google Earth Engine platform to process MODIS-NDVI raw data for format conversion, projection conversion and clipping, and exports NDVI long time series data from 2000 to 2021, and dynamic threshold method was used to obtain Inner Mongolia vegetation phenology data set from 2001 to 2020.

To improve the utilization rate of clean energy, reduce carbon emissions, and alleviate the global energy crisis and greenhouse effect, a low-carbon economic dispatch model of multi-energy park considering high proportion of new energy consumption is proposed. First, after introducing the gas storage and heat storage equipment to the park, the potential of energy coupled devices is further tapped, and the impact of electric vehicle charging mode is explored. Then, based on the stepwise price curve, a price-based integrated thermo-electric demand response model is established. Moreover, considering the low-carbon operation of the integrated energy system, a carbon capture and storage equipment model is built. Furthermore, a mixed integer linear programming model for low-carbon economic dispatch before the day of the multi-energy park is proposed. The example analysis shows that the proposed model can improve the energy utilization rate and the scheduling flexibility of the park, effectively reduce the carbon emissions of the park, increase the income of the park, and promote the consumption of high proportion of new energy.

In order to improve the compatibility between inorganic semiconductor and organic polymer semiconductor, and optimize the photoelectric performance of the battery, a hybrid solar cell of TiO2/PCPDTBT based on one dimensional inorganic TiO2 nanorods ordered arrays and organic polymer PCPDTBT is constructed. The heterojunction interface properties between the inorganic and organic materials are controlled by amphiphilic organic triphenylamine-type molecules. The properties of the hybrid films are characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), energy dispersive spectrometer (EDS), UV-vis spectra (UV-vis), photoluminescence spectroscopy (PL), etc.. The battery performance tests demonstrate that the photovoltaic performance of the modified cell is improved, and the power conversion efficiency η is of 0.81%. Open circuit voltage decay tests demonstrate that the electron lifetime is increased after heterojunction surface/interfacial modification. These results indicate that the amelioration of morphology and structure of the active layer plays an important role on solar cell performance, by means of modification of the heterojunction surface/interface.
