“…In some cases, we extend the IEA end energy use breakdown to more granular levels (e.g. road fuel split between transport modes) by supplementing Chinese end consumption data in three key areas: buildings [3,[44][45][46][47][48]; transport [49][50][51][52][53]; and industry [54][55][56][57][58].…”

“…Previous US-UK values [19] are modified by Chinese data as follows. For transport, local fuel economy data was used for road and rail [52,53,59,60]. For calculating Carnot efficiencies (for heat exergy efficiencies), for external temperatures we used 1971-2010 China monthly air temperature data [61], whilst indoor temperatures (for LTH efficiencies) were weighted for China's city/rural split and assume a 20 year lag in comfort levels versus UK data [62].…”

h i g h l i g h t sWe complete the first time series exergy and useful work study of China (1971China ( -2010. Novel exergy approach to understand China's past and future energy consumption. China's exergy efficiency rose from 5% to 13%, and is now above US (11%). Decomposition finds this is due to structural change not technical leapfrogging. Results suggests current models may underestimate China's future energy demand. a b s t r a c tThere are very few useful work and exergy analysis studies for China, and fewer still that consider how the results inform drivers of past and future energy consumption. This is surprising: China is the world's largest energy consumer, whilst exergy analysis provides a robust thermodynamic framework for analysing the technical efficiency of energy use. In response, we develop three novel sub-analyses. First we perform a long-term whole economy time-series exergy analysis for China . We find a 10-fold growth in China's useful work since 1971, which is supplied by a 4-fold increase in primary energy coupled to a 2.5-fold gain in aggregate exergy conversion efficiency to useful work: from 5% to 12.5%. Second, using index decomposition we expose the key driver of efficiency growth as not 'technological leapfrogging' but structural change: i.e. increasing reliance on thermodynamically efficient (but very energy intensive) heavy industrial activities. Third, we extend our useful work analysis to estimate China's future primary energy demand, and find values for 2030 that are significantly above mainstream projections.

foreign matter invasion is a disastrous hazard regarding the safety and stability of high speed railway. Considering the fact that foreign matter invasion forecast is not matured yet,development of foreign matter invasion warning system is a very important countermeasure for foreign matter invasion disaster mitigation. Basic principles of the foreign matter invasion warning system and its application to railways are presented. The state-of-the-art of the foreign matter invasion warning systems for high speed railways around the world is introduced. Main points in development of the foreign matter invasion warning system for high speed railways are discussed, including layout of monitoring stations and monitoring means selection, with particular attention paid to railway safety operations. The present review is expected to be of significance to the development of the early warning system for high-speed railways in China.
