Promoting conservation in buildings: A promising route

More attention would be paid to energy conservation if the property market in the UK reflected the true benefits of energy conservation improvements on the value of buildings. The benefits extend beyond the saving in fuel bills during the investor's period of occupation to a real appreciation in property value as the saving generally continues during the lifetime of the building. When the full extent of this is recognized a free market approach to investing in these measures can be more properly effective and the potential for saving up to £6 billion and for creating up to 150 000 jobs can be realized.     

On China's energy intensity statistics: Toward a comprehensive and transparent indicator

A transparent and comprehensive statistical system in China would provide an important basis for enabling a better understanding of the country. This paper focuses on energy intensity (EI), which is one of the most important indicators of China. It firstly reviews China's GDP and energy statistics, showing that China has made great improvements in recent years. The means by which EI data are released and adjusted are then explained. It shows that EI data releases do not provide complete data for calculating EI and constant GDP, which may reduce policy transparency and comprehensiveness. This paper then conducts an EI calculation method that is based on official sources and that respects the data availability of different data release times. It finds that, in general, China's EI statistics can be considered as reliable because most of the results generated by author's calculations match the figures in the official releases. However, two data biases were identified, which may necessitate supplementary information on related constant GDP values used in the official calculation of EI data. The paper concludes by proposing short- and long-term measures for improving EI statistics to provide a transparent and comprehensive EI indicator.     

Effect of the fabrication condition of membrane electrode assemblies with carbon-supported ordered PtCo electrocatalyst on the durability of polymer electrolyte membrane fuel cells

Electrode structure improvement is one of the most promising paths for improving the durability of polymer electrolyte membrane fuel cells (PEMFCs). As strategies to prevent structural deformation and enhance the durability of membrane electrode assemblies (MEAs) with structurally ordered PtCo/C-based cathodes, we evaluated the effect of hot pressing and reinforcing the electrode's structure by increasing the ionomer content. Even though the initial performances of the hot-pressed MEA (HP) and the MEA with extra cathode ionomer (EI) were lower than that of the conventional MEA (CE) by 13.6% and 19.1%, respectively, CE degraded much more significantly than HP and EI after an accelerated degradation test. Therefore, HP and EI could deliver significantly higher single cell performances than CE (22.7% and 43.7%, respectively). The improvements in the durability of HP and EI could be correlated with the structural stability which could be evaluated by structure and electrochemical analysis including electrochemical impedance spectroscopy.     

Energy conservation policies in the OECD did they make a difference?

In 1985, homes, services, automobiles, truck freight, air passenger traffic, other transport, and manufacturing in the OECD used 47 million bbl/day of oil equivalent (mb/doe), or 105 000 PJ¹ Between 1972 and 1985, however, energy use per unit of activity in each of these sectors in the OECD fell significantly. If these energy intensities, by sector, had been frozen at their 1972 values, 1985 end-use would have been close to 64 mb/doe, or 143 000 PJ, at the rates of activity that prevailed in each sector in 1985.² The difference yields a saving of 17 mb/doe. The corresponding oil savings in this period amount to close to 12 mb/doe, including substitution by other fuels. In this paper it is suggested that most of these savings will not reverse in the near time with lower oil prices; only a small part was caused by energy conservation policies.     

典型国家工业化进程中能源强度的变化及启示

能源强度是用于比较不同国家或地区经济发展对于能源依赖程度的重要指标。通过对典型国家工业化进程中能源强度变化情况进行深入分析,发现能源强度并非简单与第二产业比重、高耗能产品产量直接关联,而是更多地和工业化的内容、主导产业相关。发展用于城市扩张、基础设施建设的传统工业化会导致能源强度快速上升,而发展高附加值、高端制造业的现代化工业又可以抵消传统工业化对能源强度的拉动作用。我国目前处于传统工业化发展迅速而工业现代化发展不足的状态,同时第三产业发展相对缓慢,因此能源强度上升压力较大。实现能源强度持续下降,有赖于工业化模式的根本性转变和结构上的根本性调整。     

Smart dispatching for energy internet with complex cyber‐physical‐social systems: A parallel dispatch perspective

Energy internet (EI) is a complex coupled multienergy system; it is essential to investigate its multienergy dispatching optimization issues. To this end, this paper first proposes a novel conception of smart dispatching for EI with a complex cyber‐physical‐social system (CPSS) network from the perspective of parallel dispatch, called parallel dispatching robot (PDR), and investigates the implementations of PDR based on smart artificial society (SAS) modeling. First, we introduce EI and describe the dispatching issues of EI. Second, we discuss several important concepts supporting the parallel dispatch conception of EI, including knowledge automation (KA), CPSS, and parallel machine learning (PML). On the basis of these, we elaborate the concept of parallel dispatch. Moreover, we construct a large closed‐loop feedback control framework of parallel dispatch for EI integrating a CPSS network based on KA and PML. Third, we establish an experimental platform for PDR research based on the proposed parallel dispatch framework. Fourth, we develop the PML‐based SAS models of a single PDR in centralized dispatching modes and group PDRs in decentralized dispatching modes to achieve crowd wisdom emergence and performance improvement in current cyber‐physical system frameworks of EI. Moreover, we design an external global closed loop for PDR to evaluate its operation stability. Lastly, we conduct a detailed discussion on PDR and offer some prospects for its engineering implementations. The biggest innovation of this paper lies in systematically proposing the smart dispatching concept and framework for complex CPSS‐based EI from the perspective of parallel dispatch and thoroughly investigating how to use SAS modeling to implement parallel dispatching and control for EI considering human and social factors, which is a major extension and theoretical improvement to existing single smart wide area robot concept and a preliminary attempt in investigating a shift from Energy 4.0 to Energy 5.0 in China.
