Energy rebound effect in China’s manufacturing sector: Fresh evidence from firm-level data

《工程管理前沿（英文）》页码 439-451 doi: 10.1007/s42524-022-0210-8

摘要： The rebound effect refers to the phenomenon that individuals tend to consume more energy in the face of energy efficiency improvement, which reduces the expected energy-saving effect. Previous empirical studies on the rebound effect of regions and sectors do not provide microscopic evidence. To fill this gap, we use China’s firm-level data to estimate the rebound effect in China’s manufacturing subsectors, providing a detailed picture of China’s rebound effect across different sectors and different regions in 2001–2008. Results show that a partial rebound effect robustly appears in all industries, and the disparity between sectors is quite broad, ranging from 43.2% to 96.8%. As for the dynamic rebound effect of subsectors, most subsectors present an upward trend, whereas few subsectors show a clear downward trend. As a whole, the declined trend of the rebound effect is driven by the descent of minority sectors with high energy consumption and high energy-saving potential. In addition, we find that the disparity of the rebound effect across sectors is more significant than that across regions.

Application of nanotechnologies in the energy sector: A brief and short review

Ferric CHRISTIAN, EDITH, SELLY, Dendy ADITYAWARMAN, Antonius INDARTO

《能源前沿（英文）》 2013年第7卷第1期页码 6-18 doi: 10.1007/s11708-012-0219-5

摘要： Energy is of great importance in human life because of its benefits as the main resource for human activity. According to International Energy Agency (IEA), energy demands are expected to continue increasing until 2030. Because energy demand will never decrease, it is necessary to develop modern technology, such as nano-based technology, in order to obtain a more effective and efficient process to produce more energy. The application of nano technology or nano material in the field of energy, which involves lithium-ion battery, fuel cell, light emitting diode (LED), ultra-capacitor, and solar cell (including Gr?tzel cell), is a hot topic in many scientific researches. Unfortunately, its current development is hampered by the expensive cost of production compared to conventional technologies. Therefore, priority should be given to nano technology in the energy sector order to obtain higher efficiency, lower production cost, and easier in its application.

Comparative analysis of energy use in China building sector: current status, existing problems and solutions

Shengyuan ZHANG, Xiu YANG, Yi JIANG, Qingpeng WEI,

《能源前沿（英文）》 2010年第4卷第1期页码 2-21 doi: 10.1007/s11708-010-0023-z

摘要： Energy use in buildings has attracted more and more attention due to its significant proportion in the energy pan of the world. China is the second largest energy user, yet the situation of energy use in the China building sector remains unclear, due to problems of statistics and data processing and problematic use of these data. In this paper, a series of methods is developed, in the first place, to give strict definitions of energy data and to divide energy use into 4 sub-sectors according to the unique situation of China. Then, each sub-sector is further analyzed through international comparisons. Existing problems of energy use and solutions for energy reduction in each sub-sector are also discussed. Accordingly, it is found that China uses much less energy, in terms of both per capita and unit area, in buildings than developed countries. The difference in energy use could be attributed, in large part, to lifestyles of local people, which could determine their way of energy use but is more determined by cultural concepts than by others such as income, technique and so on, especially in China. However, to fulfill the requirements of lifestyles with higher living standards and lower energy consumption, technological innovations are needed.

Water---- and nutrient and energy---- systems in urbanizing watersheds

Rodrigo VILLARROEL WALKER, Michael Bruce BECK, Jim W. HALL

《环境科学与工程前沿（英文）》 2012年第6卷第5期页码 596-611 doi: 10.1007/s11783-012-0445-4

摘要： Driven by considerations of sustainability, it has become increasingly difficult over the past 15–20 years — at least intellectually — to separate out the water infrastructure and water metabolism of cities from their intimately inter-related nutrient and energy metabolisms. Much of the focus of this difficulty settles on the wastewater component of the city’s water infrastructure and its associated fluxes of nutrients (N, P, C, and so on). Indeed, notwithstanding the massive volumes of these materials flowing into and out of the city, the notion of an urban nutrient infrastructure is conspicuous by its absence. Likewise, we do not tend to discuss, or conduct research into, “soilshed” agencies, or soilshed management, or Integrated Nutrient Resources Management (as opposed to its most familiar companion, Integrated Water Resources Management, or IWRM). The paper summarizes some of the benefits (and challenges) deriving from adopting this broader, multi-sectoral “systems” perspective on addressing water-nutrient-energy systems in city-watershed settings. Such a perspective resonates with the growing interest in broader policy circles in what is called the “water-food-energy security nexus”. The benefits and challenges of our Multi-sectoral Systems Analysis (MSA) are illustrated through computational results from two primary case studies: Atlanta, Georgia, USA; and London, UK. Since our work is part of the International Network on Cities as Forces for Good in the Environment (CFG; see www.cfgnet.org), in which other case studies are currently being initiated — for example, on Kathmandu, Nepal — we close by reflecting upon these issues of water-nutrient-energy systems in three urban settings with quite different styles and speeds of development.

Real prospects for the development of power technologies based on renewable energy sources in Poland

Sławomir DYKAS, Artur SZYMAŃSKI, Xiaoshu CAI

《能源前沿（英文）》 2017年第11卷第2期页码 168-174 doi: 10.1007/s11708-017-0474-6

摘要： In Poland more than 40% of the power units have been operating for over 40 years now and more than 10% are over 50 years old, which indicates a high degree of decrease in the value of the energy sector. An analysis of the energy market shows that every year a new power plant should be built with a capacity of 1000 MW to ensure the national energy security. An energy market research indicates that in Poland the structure of energy production is changing in recent years—the share of fossil (solid) fuels in electricity and heat production was approximately 88% in 2009, while in 2004 it reached 93%. According to the analysis of the market, it can be seen that conventional energy, mainly based on coal and lignite, has been the most important segment of the sector for a long time.?In this paper the prospects for the development of power technologies based on renewable energy sources (RES) in Poland are presented.

Fidelis I. ABAM,Olayinka S. OHUNAKIN,Bethrand N. NWANKWOJIKE,Ekwe B. EKWE

《能源前沿（英文）》 2014年第8卷第3期页码 322-334 doi: 10.1007/s11708-014-0329-3

摘要： In this paper, the end-use efficiencies of the different energy carriers and the overall energy efficiency in the Nigerian residential sector (NRS) were estimated using energy and exergy analysis. The energy and exergy flows were considered from 2006 to 2011. The overall energy efficiency ranges from 19.15% in 2006 to 20.19% in 2011 with a mean of (19.96±0.23)% while the overall exergy efficiency ranges from 4.34% in 2006 to 4.40% in 2011 with a mean of (4.31±0.059)%. The energy and exergy efficiency margin was 15.58% with a marginal improvement of 0.07% and 0.02%, respectively when compared with previous results. The contribution of the energy carriers to the total energy and exergy inputs were 1.45% and 1.43% for electricity, 1.95% and 3% for fossil fuel and 96.6% and 95.57% for bio-fuel. The result shows that approximately 65% of the residence use wood and biomass for domestic cooking and heating, and only a fraction of the residence have access to electricity. LPG was found to be the most efficient while kerosene, charcoal, wood and other biomass the least in this order. Electricity utilization exergy efficiency is affected by vapor-compression air conditioning application apart from low potential energy applications. In addition, this paper has suggested alternatives in the end-use application and has demonstrated the relevance of exergy analysis in enhancing sustainable energy policies and management and improved integration techniques.

State versus private sector provision of water services in Armenia

Naira HARUTYUNYAN

《环境科学与工程前沿（英文）》 2012年第6卷第5期页码 620-630 doi: 10.1007/s11783-012-0425-8

摘要： Despite increasing advocacy and adaptation of public-private model of water governance worldwide since the 1990s, today only 5% of the world’s population is served by water utilities with private involvement. The present article examines the experience of the water sector in Armenia with private sector participation. The study describes the process of the introduction of public-private partnerships in the water sector and focuses on analyzing the impact of privatization on water utility performance. The analysis employs the partial indicator method for evaluating the impacts in relation to operational, finance, and environmental performance, done by drawing on the database for the five water companies in Armenia. The empirical evidence shows that private participation in general led to improved overall performance. In particular, private involvement resulted in increased operational efficiency in terms of labor productivity, water metering, continuity of service, and revenue collection efficiency. There were mixed improvements in the operating cost coverage ratio. As for environmental performance, there were gains in the reduction of residential water consumption, accompanied, however, by an increase in non-revenue water.

《能源前沿（英文）》 2021年第15卷第2期页码 473-486 doi: 10.1007/s11708-021-0738-z

摘要： Low-carbon energy technology (LC) innovation contributes to both environmental protection and economic development. Using the panel data of 30 provinces/autonomous regions/municipalities in China from 1998 to 2017, this paper constructs a two-layer logarithmic mean Divisia index (LMDI) model to uncover the factors influencing the variation of the innovation of LC in China’s industrial sectors, including the alternative energy production technology (AEPT) and the energy conversation technology (ECT). The results show that China’s industrial LC patent applications rapidly increased after 2005 and AEPT patent applications outweighed ECT patent applications all the time with a gradually narrowing gap. Low-carbon degree played the dominant role in promoting the increase in China’s industrial LC patent applications, followed by the economic scale, R&D (research and development) efficiency, and R&D share. Economic structure contributed to the increases in LC patent applications in the central and the western regions, while led to the decreases in the eastern region, the north-eastern region, and Chinese mainland . Low-carbon degree and economic scale were two main contributors to the growths of both industrial AEPT patent applications and ECT patent applications in Chinese mainland and the four regions. Several policy recommendations are made to further promote industrial innovation in China.

《能源前沿（英文）》 2018年第12卷第3期页码 400-410 doi: 10.1007/s11708-018-0565-z

摘要：

Waste management is becoming a crucial issue in modern society owing to rapid urbanization and the increasing generation of municipal solid waste (MSW). This paper evaluates the carbon footprint of the waste management sector to identify direct and indirect carbon emissions, waste recycling carbon emission using a hybrid life cycle assessment and input-output analysis. China and Japan was selected as case study areas to highlight the effects of different industries on waste management. The results show that the life cycle carbon footprints for waste treatment are 59.01 million tons in China and 7.01 million tons in Japan. The gap between these footprints is caused by the different waste management systems and treatment processes used in the two countries. For indirect carbon footprints, China’s material carbon footprint and depreciation carbon footprint are much higher than those of Japan, whereas the purchased electricity and heat carbon footprint in China is half that of Japan. China and Japan have similar direct energy consumption carbon footprints. However, CO₂emissions from MSW treatment processes in China (46.46 million tons) is significantly higher than that in Japan (2.72 million tons). The corresponding effects of waste recycling on CO₂ emission reductions are considerable, up to 181.37 million tons for China and 96.76 million tons for Japan. Besides, measures were further proposed for optimizing waste management systems in the two countries. In addition, it is argued that the advanced experience that developed countries have in waste management issues can provide scientific support for waste treatment in developing countries such as China.

Will Germany move into a situation with unsecured power supply?

Harald SCHWARZ

《能源前沿（英文）》 2019年第13卷第3期页码 551-570 doi: 10.1007/s11708-019-0641-z

摘要： Together with a huge number of other countries, Germany signed the Paris Agreements in 2015 to prevent global temperature increase above 2°C. Within this agreement, all countries defined their own national contributions to CO reduction. Since that, it was visible that CO emissions in Germany decreased, but not so fast than proposed in this German nationally determined contribution to the Paris Agreement. Due to increasing traffic, CO emissions from this mobility sector increased and CO emission from German power generation is nearly constant for the past 20 years, even a renewable generation capacity of 112 GW was built up in 2017, which is much higher than the peak load of 84 GW in Germany. That is why the German National Government has implemented a commission (often called “The German Coal Commission”) to propose a time line: how Germany can move out of coal-fired power stations. This “Coal Commission” started its work in the late spring of 2018 and handed over its final report with 336 pages to the government on January 26th, 2019. Within this report the following proposals were made: ① Until 2022: Due to a former decision of the German Government, the actual remaining nuclear power generation capacity of about 10 GW has to be switched off in 2022. Besides, the “Coal Commission” proposed to switch off additionally in total 12.5 GW of both, hard coal and lignite-fired power plants, so that Germany should reduce its conventional generation capacity by 22.5 GW in 2022. ② Until 2030: Another 13 GW of German hard coal or lignite-fired power plants should be switched off. ③ Until 2038: The final 17 GW of German hard coal or lignite-fired power plants should be switched off until 2038 latest. Unfortunately the “Coal Commission” has not investigated the relevant technical parameter to ensure a secured electric power supply, based on German’s own national resources. Because German Energy Revolution mainly is based on wind energy and photovoltaic, this paper will describe the negligible contribution of these sources to the secured generation capacity, which will be needed for a reliable power supply. In addition, it will discuss several technical options to integrate wind energy and photovoltaic into a secured power supply system with an overall reduced CO emission.
