addressing leakage in the eu ets border adjustment or output based allocation the eu ets has been criticised for threatening the competitiveness of european industry and generating carbon leakage i e increasing foreign greenhouse gas emissions two main options have been put forward to tackle these concerns border adjustments and output based allocation i e allocation of free allowances in proportion to current production we compare various configurations of these two options as well as a scenario with full auctioning and no border adjustment against this background we develop a model of the main sectors covered by the eu ets electricity steel cement and aluminium we conclude that the most efficient way to tackle leakage is auctioning with border adjustment which generally induces a negative leakage a spillover this holds even if the border adjustment does not include indirect emissions if it is based on eu rather than foreign specific emissions or for some values of the parameters if it covers only imports another relatively efficient policy is to combine auctioning in the electricity sector and output based allocation in exposed industries especially if free allowances are given both for direct and indirect emissions i e those generated by the generation of the electricity consumed although output based allocation is generally less effective than border adjustment to tackle leakage it is more effective to mitigate production losses in the sectors affected by the ets which may ease climate policy adoption c 2011 elsevier b v all rights reserved

energy security in asean a quantitative approach for sustainable energy policy abstract we investigate energy security of the association of southeast asian nations asean under the 4 a s framework the asean economic community aec agreement launched in 2015 renewed a regional focus on energy security and sustainability we employ an analytic framework to quantitatively assess progress in different categories including availability acceptability affordability and applicability key metrics include the documentation of co 2 emissions energy access measures and energy supply reserves from 2005 2010 we identify relevant energy indicators using high quality historical data from the iea and world bank we find that asean made little progress toward establishing energy security in the previous five year planning period 2005 2010 as it regressed in most categories except applicability therefore we suggest that increased development of renewable energy and energy efficiency technologies would move asean in a positive direction toward achieving energy security and sustainable energy policy goals

the energy transition of the transition economies an empirical analysis the aggregate manufacturing energy intensity of 28 countries in eastern europe and central asia had declined by 35 percent during 1998 2008 this study reveals strong evidence of convergence less efficient countries improved more rapidly and the cross country variance in energy productivity narrowed over time an index decomposition analysis indicates that energy intensities declined largely because of more efficient energy use rather than shifts from energy intensive to less intensive manufacturing activities income growth and energy price increases were the main drivers of the convergence they dominated the impact of trade which led to specialization in energy intensive industries

dynamics and determinants of energy intensity in the service sector a cross country analysis 1980 2005 we present a detailed analysis of energy intensity developments across 23 service sectors in 18 oecd countries over the period 1980 2005 we find that the shift towards a service economy has contributed to lower overall energy intensity levels in the oecd but this contribution would have been considerably larger if the service sector had realized the same degree of energy efficiency improvements as the manufacturing sector in most oecd countries energy intensity levels in services tend to decrease relatively slow especially after 1995 if we control this trend for the impact of structural changes within the services sector by means of a decomposition analysis we find that in about one third of the oecd countries energy intensity levels in services have increased over time the impact of structural changes on aggregate energy intensity dynamics in services has increased considerably after 1995 highlighting a relatively poor energy efficiency performance within a wide range of service sectors we show that the introduction of information and communication technology ict plays a potentially important role here using panel data regression analysis we find a limited role for energy prices in explaining variation in energy productivity while climate conditions clearly impact energy productivity

energy metrics for driving competitiveness of countries energy weakness magnitude gdp per barrel and barrels per capita abstract energy metrics is the development of a whole new theoretical framework for the conception and measurement of energy and economic system performances energy efficiency and productivity improvements with important political economy implications consistent with the best use of all natural and economic resources the purpose of this research is to present some vital energy indicators based on magnitude and scale of energy weakness gdp per barrel of oil that is an indicator of energy productivity and barrels of oil per capita that is an indicator of energy efficiency energy metrics can support the monitoring of energy and economic system performances in order to design effective energy strategy and political economy interventions focused on the competitive advantage increase of countries in modern economies

account for sector heterogeneity in china s energy consumption sector price indices vs gdp deflator abstract a common practice in decomposition analyses is to deflate output indicators to purge the impact of inflation by using a general deflator this practice fails to account for sector heterogeneity and can be hazardous although the general identified patterns are largely correct the calculated magnitudes can be misleading or even wrongly signed instead it is strongly recommended that sector heterogeneity is accounted for by using individual sector price indices for all relevant sectors instead of one general gdp deflator this paper analyzes this advanced decomposition using chinese data and compares to the usual method of using only one deflator it is found that while most differences are only of quantitative quality some show even a qualitative difference furthermore the rising energy intensity in the early 2000s which has been discussed by previous studies vanishes completely

energy embodied in the international trade of china an energy input output analysis abstract growing international trade has not only positively affected the people s republic of china s china s economic development but also expanded the exportation of energy embodied in goods during their production this energy flow out will pose risks to china s rational utilization of natural resources as well as environmental protection in this paper we evaluate the energy embodied in goods produced in china during 1992 2005 and use input output structural decomposition analysis to identify five key factors causing the changes of energy embodied in exports direct primary energy efficiency primary energy consumption structure structure of intermediate inputs structure of exports and scale of exports for the three sub periods of 1992 1997 1997 2002 and 2002 2005 results show that china is a net exporter of energy and the energy embodied in exports tends to increase over time the expanding total volume of exports and increasing exports of energy intensive goods tend to enlarge the energy embodied in exports within all three sub periods but these driving forces were offset by a considerable improvement of energy efficiency and changes in primary energy consumption structure from 1992 to 2002 and the effects of structure of intermediate input only in the sub period from 1992 to 1997 from 2002 to 2005 the sharp augmentation of energy embodied in exports was driven by all the five factors our research has practical implications for the chinese economy results of this study suggest that the energy embodied in trade should receive special attentions in energy policies design to limit the energy resource out flow and pollution generation

measuring energy efficiency in the context of an emerging economy the case of indian manufacturing in recent years the indian economy has achieved a rapid growth rate however one of the challenges facing the economy is the large energy supply that would be needed to sustain this growth path hence attaining energy efficiency is crucial for the economy this paper examines the indian manufacturing sector and utilizes a variant of the directional distance function to obtain comprehensive measures of performance of the major manufacturing states given the joint goals of achieving energy conservation and output growth the results of the empirical application reveal that given the prevailing technology the average manufacturing firm across the states could reduce energy input and increase output simultaneously by an annual average of 3 84 by improving technical efficiency to accommodate a larger simultaneous increase in output and reduction in energy use india should adopt superior technologies so as to shift the efficient frontier outward

why did the energy intensity fall in china s industrial sector in the 1990s the relative importance of structural change and intensity change there have been a variety of studies investigating the relative importance of structural change and real intensity change to the change in china s energy consumption in the 1980s however no detailed analysis to date has been done to examine whether or not the increased energy efficiency trend in the 1980s still prevailed in the 1990s this article has filled this gap by investigating the change in energy consumption in china s industrial sector in the 1990s based on the data sets of value added and end use energy consumption for the 29 industrial subsectors and using the newly proposed decomposition method of giving no residual our results clearly show that the overwhelming contributor to the decline in industrial energy use in the 1990s was the decline in real energy intensity indicating that the trend of real energy intensity declines in the 1980s at the 2 digit level was still maintained in the 1990s this conclusion still holds even if we lower the growth rate dramatically in line with the belief that the growth rate of china s gdp may be overestimated

index decomposition analysis applied to co2 emission studies index decomposition analysis ida was first extended from energy consumption to energy related co2 emission studies in 1991 since then many studies have been reported covering various countries and emission sectors however unlike the case of energy consumption studies a comprehensive literature survey that focuses specifically on emission studies has so far not been reported in this paper we attempt to fill this gap by reviewing 80 papers appearing in peer reviewed journals from 1991 to 2012 in this application area the first part of this paper deals with the developments with regard to the ida approaches used by researchers and the scope and focus of their studies in the second part the empirical results reported in the surveyed studies are analyzed consolidated and presented by emission sector the objective is to reveal the relative contributions of key effects on changes in the aggregate carbon intensity and this is done by emission sector and by country the findings of both parts are useful in understanding the development of ida in the application area of emission study as well as the key drivers of aggregate carbon intensities in the past and their possible future developments

what drives the change in china s energy intensity combining decomposition analysis and econometric analysis at the provincial level abstract we employ decomposition analysis and econometric analysis to investigate the driving forces behind china s changing energy intensity using a provincial level panel data set for the period from 1995 to 2009 the decomposition analysis indicates that a all of the provinces except for a few experienced efficiency improvement while around three fourths of the provinces economics became more energy intensive or remained unchanged b consequently the efficiency improvement accounts for more than 90 of china s energy intensity change as opposed to the economic structural change the econometric analysis shows that the rising income plays a significant role in the reduction of energy intensity while the effect of energy price is relatively limited the result may reflect the urgency of deregulating the price and establishing a market oriented pricing system in china s energy sector the implementation of the energy intensity reduction policies in the eleventh five year plan fyp has helped reverse the increasing trend of energy intensity since 2002 although the chinese government intended to change the industry led economic growth pattern it seems that most of the policy effects flow through the efficiency improvement as opposed to the economic structure adjustment more fundamental changes to the economic structure are needed to achieve more sustainable progress in energy intensity reduction

manufacturing energy use in oecd countries decomposition of long term trends abstract in this paper we examine manufacturing energy use in 13 oecd countries over the period 1971 1995 we describe changes in aggregate energy intensity using the adaptive weighting divisia decomposition method we contrast the development in the periods after the oil price shocks of 1973 and 1979 with the period of relatively stable energy prices after the oil price crash of 1986 the results show that manufacturing output grew in most countries pushing up energy use the share of electricity increased in almost every sector while there was a clear trend away from oil and coal towards natural gas changes in the structure of output drove up energy use between 1973 and 1994 in some countries and down in others changes in energy intensities had a profound and downward effect on manufacturing energy use in all countries however contrasting the period after oil prices fell in 1986 with earlier years we see that for most countries the rate of energy intensity decline slowed slightly but did not reverse with falling prices in a few countries efficiency improvements continued to have a strong effect this suggests that even without higher prices improvements of energy efficiency seems to take place

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

embedding the drivers of emission efficiency at regional level analyses of namea data abstract this paper provides new empirical evidence on regional national disparities in environmental efficiency based on analyses of namea data referring to italy and the lazio region where rome is the main city shift share analyses provide evidence on the drivers of environmental efficiency and on sector specificity our evidence shows that although the region around rome has achieved higher environmental performance compared to italy mainly thank to its being less industry based some critical points in the energy sector and in some services should be taken into account in shaping the future development of the region in addition the use of regional namea for econometric investigations of emission efficiency drivers at national level shows that though north south disparities favour northern and richer regions in accordance with development oriented dynamics environmental hot spots driven by specialisation and efficiency related issues also appear in some northern industrial regions further the role of public ad private r d is of main relevance in enhancing emission on economic value ratios environmental industrial and sector oriented policy making may derive valuable information from the evidence provided by our study that highlights how analytical exploitation of namea offers rich array of insights for regional policy making

reaping the carbon rent abatement and overallocation profits in the european cement industry insights from an lmdi decomposition analysis we analyse variations of carbon emissions in the european cement industry from 1990 to 2012 at the european level eu 27 and at the national level for six major producers germany france spain the united kingdom italy and poland we apply a log mean divisia index lmdi method cross referencing data from three databases the getting the numbers right gnr database developed by the cement sustainability initiative the european union transaction log eutl and the eurostat international trade database our decomposition method allows seven channels of emission change to be distinguished activity clinker trade clinker share alternative fuels thermal and electrical energy efficiency and electricity decarbonisation we find that apart from a slow trend of emission reductions coming from technological improvements first from a decrease in the clinker share then from an increase in alternative fuels most of the emission change can be attributed to the activity effect using counterfactual scenarios we estimate that the introduction of the eu ets brought small but positive technological abatement 2 2 1 3 between 2005 and 2012 moreover we find that the european cement industry has gained 3 5 billion euros of overallocation profits mostly due to the slowdown of production

debt covenant violation and manipulation of accruals abstract this paper examines the abnormal accruals of a sample of 94 firms that reported debt covenant violations in annual reports we expect debt covenant restrictions to influence accounting choices in the year preceding and the year of violation time series and cross sectional models are used to estimate normal accruals in the year prior to violation both models indicate that abnormal total and working capital accruals are significantly positive in the year of violation there is evidence of positive abnormal working capital accruals after controlling for management changes and auditor going concern qualifications

structural change and energy efficiency in industry the change in the ratio of energy consumed to industrial production is examined over the years 1968 1980 changes in the composition of industry are analysed creating a better picture of movements in physical efficiency of energy use the medium term trends show the significance of the 1973 oil crisis the effects being contrary to those of intuition the implications of the two recessions for efficiency and industrial structure are described in detail the role of demand often relegated to an incidental consideration is brought to the fore in the years following 1973 it appears more important than ex post substitution in production and with this comes a particular implication for the use of aggregate production functions

structural change and technology choice energy use in mexican manufacturing industry 1970 1981 abstract this paper analyses industrial energy use in a country that has experienced falling instead of rising energy prices mexico subsidizes domestic energy consumption with the avowed purpose of stimulating industrialization methods are developed to distinguish the effects of technology choice from the effects of changing industrial structure and are then used to analyse the increased energy intensity of manufacturing industry 1970 1981 the increase is found to depend entirely on the adoption of more energy using technology whereas the changes in output structure have had little or no effect there has been a slight bias in favour of the less energy intensive sectors

measuring energy rebound effect in the chinese economy an economic accounting approach estimating the magnitude of china s economy wide rebound effect has attracted much attention in recent years most existing studies measure the rebound effect through the additional energy consumption from technological progress however in general technological progress is not equivalent to energy efficiency improvement consequently their estimation may be misleading to overcome the limitation this paper develops an alternative approach for estimating energy rebound effect based on the proposed approach china s economy wide energy rebound effect is revisited the empirical result shows that during the period 1981 2011 the rebound effects in china are between 30 and 40 with an average value of 34 3

what is the role of openness for china s aggregate industrial so2 emission a structural analysis based on the divisia decomposition method abstract having observed the weaknesses in previous structural analyses on the role of environmental kuznets curve ekc the author proposes a detailed analysis using a rich data set of provincial level production and so2 emission intensity of 13 industrial sectors the latter represent more than 98 of the total industrial production in each chinese province for the period 1991 2001 through the use of the log mean divisia index decomposition method the variations in province level industrial so2 emissions with regard to the 1990 baseline level are decomposed into the contribution from three components scale composition and technical effects the following analysis seeks to explain how trade openness affects aggregate industrial so2 emission through its impact on the structural determinants for these three components of region specific environmental variations

does energy efficiency promote economic growth evidence from a multicountry and multisectoral panel dataset abstract we examine the causal relationship between energy efficiency and economic growth based on panel data for 56 high and middle income economies from 1978 to 2012 using a panel vector autoregression approach we find evidence of a long run granger causality from economic growth to lower energy intensity for all economies we also find evidence of long run bidirectional causality between lower energy intensity and higher economic growth for middle income economies this finding suggests that beyond climate benefits middle income economies may also earn an extra growth dividend from energy efficiency measures

swedish co2 emissions 1993 2006 an application of decomposition analysis and some methodological insights this study undertakes a decomposition analysis to identify the drivers of carbon dioxide emissions change in the swedish business and industry sectors 1993 2006 on aggregate energy intensity decreased but this does not seem to have been very important for reducing emissions rather fuel substitution seems to have been more important which is in line with findings from the decomposition literature on sweden however at the sectoral level we find no clear pattern of the effect of fuel substitution and energy intensity on emissions we also draw some methodological conclusions decomposition analysis should be undertaken at the most disaggregate level possible assessing decomposition results by summing results over several time periods leads to biased results and decomposition analysis should not be based only on some initial and final years of a long time period furthermore we address the problem of double counting energy flows in decomposition analysis of aggregate effects when the energy sector is included and point out potential problems related to output measured in monetary terms

modeling of industrial energy consumption an introduction and context industrial energy accounts for roughly one third of total global energy consumption and is expected to continue to use a similar share in the foreseeable future however this is one of the hardest end uses to analyze model and forecast the reasons for modeling industrial energy consumption are as varied as the ways in which energy is used in production processes this has led to the application of a broad set of emperical tools from several different disciplines in this article we provide an introduction and context for a compendium or survey of the methods used in this area this special issue of energy economics is designed to provide both newcomers and accomplished researchers with an overview of the current state of development in the are of industrial energy modeling

measuring structural change and energy use decomposition of the us economy from 1997 to 2002 abstract the steadily increasing focus on energy production and consumption has led to growing research attention to patterns of energy use within economies of particular interest has been comparing the driving forces of increasing efficiency and economic structural change input output analysis ioa and decomposition analysis have become critical tools for performing such analyses this study analyzes aggregate energy use in the united states in 1997 and 2002 to discover the causes of changing energy usage and flows results show that rising population and household consumption acted to drive up energy demand but this driving force was offset by considerable structural change within the economy particularly related to a quickly increasing trade deficit in manufacturing goods thus while total energy intensity the ratio of energy use to economic output declined by approximately 12 between 1997 and 2002 changes in the structure of the economy explain this drop more than increased energy efficiency the level of aggregation at which decomposition analyses are run was identified as a crucially sensitive parameter for the determination of structural change and future studies should specifically address the amount of detail necessary to adequately measure changes in economic structure

energy efficiency in the manufacturing sector of the oecd analysis of price elasticities abstract we examine the role prices have on energy efficiency in the oecd manufacturing sector between 1980 and 2009 we employ a two step procedure first we decompose manufacturing energy intensity change into two driving effects efficiency and structural change the second step uses panel time series regression techniques to estimate the impacts of prices on the effects driving manufacturing energy intensity the advantage of using these techniques is that they account for heterogeneity and cross section dependence in the data something recent energy intensity research has emphasised the results from this decomposition support existing findings that efficiency is the major driver for observed reduction in energy intensity further the second stage results indicate that rising prices improve efficiency importantly these effects vary across countries

efficiency assessment of hydroelectric power plants in canada a multi criteria decision making approach abstract hydropower plays a major role in the canadian electricity generation industry few attempts have been made however to assess the efficiency of hydropower generation in canada this paper analyzes the overall efficiency of hydropower generation in canada from comprehensive viewpoints of electricity generating capability its profitability as well as environmental benefits and social responsibility using the topsis the technique for order preference by similarity to ideal solution method the factors that influence the efficiency of the hydropower generation are also presented to help to the sustainable hydropower production in canada the most important results of this study concern 1 the pivotal roles of energy saving and of the social responsibility in the overall efficiency of hydropower corporates and 2 the lower hydropower generation efficiency of some of the most important economic regions in canada other results reveal that the overall efficiency of hydropower generation in canada experienced an improvement in 2012 following a downtrend from 2005 to 2011 amidst these influencing factors energy saving and social responsibility are key factors in the overall efficiency scores while management defined herein by the number of employees and hydropower stations of a corporation has only a slightly negative impact on the overall efficiency score

measuring argentinaâ s gdp growth the main purpose of this paper is to report on the results of an exhaustive reworking of argentina s output growth by industry realized by the arklems land argentina productivity and competitiveness project the aim was to reproduce a gdp time series since 1993 using traditional argentinean national accounting methodology in order to check economic growth against official statistics produced after political intervention in the work of the national statistics institute since 2007 the reproduced arklems gdp series closely approximates to official gdp between 1993 and 2007 at macro and industry level but after 2007 official series showed a higher growth than arklems reproducible 29 4 official gdp vs 15 9 arklems gdp for 2007 2012 however the gap between the series is not related to the use of biased cpi deflators but it is due to the abandoning of traditional methodology followed by argentinean national accounts prior to its intervention the paper shows that argentina s recent growth episode of 2002 2012 was similar to the previous positive growth cycle period of 1990 1998 argentina was not the growth champion of the latin america region during the later period but it has one of the highest rates of volatility of gdp across latin america argentine official gdp data has been subject to the so called pandora s box effect as a result of the political intervention in the production of official statistics

factors shaping aggregate energy intensity trend for industry energy intensity versus product mix understanding the mechanisms of change of energy consumption in industry has attracted much attention since the 1973 world oil crisis a popular line of research has been to decompose changes in the aggregate energy intensity of industry to give the relative impacts arising from energy intensity change and product mix change using a decomposition technique many empirical studies covering a large number of countries have been reported the main objective of this paper is to put together the empirical results reported in these studies in a coherent framework and identify possible systematic features of particular interest are the basic trends in this line of research the relative importance of energy intensity change and product mix change possible variations over time and between country groups in the energy impacts of these changes and inconsistencies in findings among studies an overview of the decomposition technique including its strengths weaknesses and role in industrial energy consumption studies is also presented

residential energy consumption in urban china a decomposition analysis abstract residential energy consumption rec is the second largest energy use category 10 in china and urban residents account for 63 of the rec understanding the underlying drivers of variations of urban rec thus helps to identify challenges and opportunities and provide advices for future policy measures this paper applies the lmdi method to a decomposition of china s urban rec during the period of 1998 2007 at disaggregated product activity level using data collected from a wide range of sources our results have shown an extensive structure change towards a more energy intensive household consumption structure as well as an intensive structure change towards high quality and cleaner energy such as electricity oil and natural gas which reflects a changing lifestyle and consumption mode in pursuit of a higher level of comfort convenience and environmental protection we have also found that china s price reforms in the energy sector have contributed to a reduction of rec while scale factors including increased urban population and income levels have played a key role in the rapid growth of rec we suggest that further deregulation in energy prices and regulatory as well as voluntary energy efficiency and conservation policies in the residential sector should be promoted

attribution of changes in divisia real energy intensity index an extension to index decomposition analysis abstract in this paper we extend the methodology of index decomposition analysis ida in energy studies by quantifying the contribution of individual attributes to the percent change of factors such as the real energy intensity index and structural change index we apply the proposed method to the real energy intensity index in the multiplicative logarithmic mean divisia index m lmdi approach a major ida technique since the m lmdi is based on geometric mean type indices and chain computation we need some appropriate method to cope with the difficulties that arise we present a numerical illustration of the proposed method using the energy consumption and real value added data of the us manufacturing industry and compare the results obtained by the fisher real energy intensity index

dutch sectoral energy intensity developments in international perspective 1987 2005 this paper makes use of a new dataset to investigate energy intensity developments in the netherlands over the period 1987 2005 the dataset allows for a comparison with 18 other oecd countries a key feature of our analysis is that we combine a cross country perspective with a high level of sectoral detail covering 49 sectors particularly innovative is our evaluation of energy intensity developments in a wide range of service sectors we find that across sectors energy intensity levels in the netherlands on average decreased only marginally and increased in services this performance is in general worse than the oecd average especially between 1987 and 1995 changes in the sectoral composition of the economy play an important role in explaining aggregate trends in the manufacturing sector about half of the efficiency improvements were undone by a shift towards a more energy intensive industry structure in contrast in the service sector efficiency decreased which was undone for about one third by a shift towards a less energy intensive sector structure

structural change and convergence of energy intensity across oecd countries 1970 2005 abstract this paper uses new and unique data derived from a consistent framework of national accounts to compute and evaluate energy intensity developments across 18 oecd countries and 50 sectors over the period 1970 2005 we find that across countries energy intensity levels tend to decrease in most manufacturing sectors in the service sector energy intensity decreases at a relatively slow rate with diverse trends across sub sectors a decomposition analysis reveals that changes in the sectoral composition of the economy explain a considerable and increasing part of aggregate energy intensity dynamics a convergence analysis reveals that only after 1995 cross country variation in aggregate energy intensity levels clearly tends to decrease driven by a strong and robust trend break in manufacturing and enhanced convergence in services moreover we find evidence for the hypothesis that across sectors lagging countries are catching up with leading countries with rates of convergence that are on average higher in services than in manufacturing aggregate convergence patterns are almost exclusively caused by convergence of within sector energy intensity levels and not by convergence of the sectoral composition of economies

analysis and decomposition of energy consumption in the chilean industry abstract with rising energy costs and climate change concerns energy efficiency will be important in maintaining competitiveness and reducing the environmental impact of industrial activities in this paper we study the chilean industrial sector which is the largest consumer of energy within the country energy demand and co 2 emissions in chile have grown rapidly in recent years while energy supply is mostly imported and subject to disruption therefore it is important to understand energy consumption in this sector and determine which sub sectors have the greatest potential to reduce energy consumption we used the index decomposition analysis ida applying the logarithmic mean divisia index method i lmdi i to quantify the impact of diverse driving factors on energy consumption furthermore a panel data analysis was used to determine whether there are differences in energy intensity across firms with different characteristics our results show that energy intensity has risen over time although energy consumption remains stable this fact supports the idea that energy efficiency policies could play an important role for the industrial sector additionally energy consumption and energy intensity follow different patterns in each sub sector therefore we conclude that the application of differentiated sectoral policies is preferable over a single global policy

energy intensity and firm growth abstract using micro level data we attempt to identify the causal relationship between improvement decline in energy intensity and firm growth in six countries namely france germany japan korea the u k and the u s and 21 manufacturing industries during the period 1991 to 2005 we run a panel regression of firm growth using the inverse of a country and industry specific relative energy intensity rei measure with the corresponding industrial sector in the reference case the u s industry in addition to the inverse of the traditional energy intensity measure ei after controlling several firm industry and country variables we find that ei and rei may have somewhat different impacts on firm growth in terms of profits and capital accumulation when we control the heterogeneity in industrial dependence on energy firm profits in the industry club with lower rei grow faster than the six country average compared to the six country case we find that the efficient use of energy inputs has made a smaller contribution to firm growth in korea

structural change and energy use the case of the manufacturing sector in taiwan abstract this paper examines the role of sectoral shift and improvements in energy intensity of individual industries in aggregate manufacturing sector energy intensity changes in taiwan during 1971 1985 the divisia index approach is employed to decompose sectoral shift and energy intensity effects a major finding of this analysis is that changes in energy intensities of individual industries were the main influence in changes in aggregate manufacturing sector fuel and electricity intensities during the period sectoral shifts were found to contribute very little to the energy intensity changes

lmdi decomposition approach a guide for implementation since it was first used by researchers to analyze industrial electricity consumption in the early 1980s index decomposition analysis ida has been widely adopted in energy and emission studies lately its use as the analytical component of accounting frameworks for tracking economy wide energy efficiency trends has attracted considerable attention and interest among policy makers the last comprehensive literature review of ida was reported in 2000 which is some years back after giving an update and presenting the key trends in the last 15 years this study focuses on the implementation issues of the logarithmic mean divisia index lmdi decomposition methods in view of their dominance in ida in recent years eight lmdi models are presented and their origin decomposition formulae and strengths and weaknesses are summarized guidelines on the choice among these models are provided to assist users in implementation

energy decomposition analysis iea model versus other methods abstract in energy decomposition analysis the international energy agency iea model which is based on the laspeyres index method is included in a recent international collaborative initiative on energy indicators for sustainable development for possible adoption iaea 2005 energy indicators for sustainable development guidelines and methodology international atomic energy agency vienna www pub iaea org mtcd publications pdf pub1222 web pdf from an empirical analysis using the data of the united states we found that the residual term given by the iea model could be significant and that the estimates of the impacts of structure and intensity changes given by the model could be quite different from those given by other decomposition methods the residual term tends to be large when changes in structure and or energy intensity variables are significant since changes in these variables over time are generally larger in the developing countries than in the iea countries there is the question about whether the iea model is an appropriate decomposition method for the developing countries

disaggregated analysis of us energy consumption in the 1990s evidence of the effects of the internet and rapid economic growth abstract this paper decomposes us energy use from 1988 to 1998 and attributes the changes in energy use to three underlying factors activity structure and intensity for this study we use a bottom up methodology by separately decomposing delivered energy use in six sectors travel freight manufacturing industries non manufacturing industries residential and services the most commonly used indicator of energy efficiency in the total economy the ratio of energy consumed to unit of gdp e gdp created can often be misleading the rapid decline in the e gdp ratio in recent years has been used to support assertions that the internet and information technologies in general have enabled improvements in energy efficiencies however our disaggregate analysis suggests that energy intensities on average are falling more slowly than ever before while actual energy use increased faster than at any time since 1970 the decline in the e gdp ratio in the mid to late 1990s owes much more to structural changes in the demand for energy services than to falling energy intensities

industry energy use and structural change a case study of the people s republic of china abstract this paper examines the effects of structural change and improvements in energy intensities of individual industries in aggregate industry energy intensity changes in china during 1980 88 the divisia index is used to decompose the energy intensity effect and structural effect a major finding of this analysis is that the main contribution to changed aggregate energy intensity was from the changes in energy intensities of individual industries during the period structural effects were found to contribute little to the aggregate energy intensity changes

toward a more reliable picture of the economic activity an application to argentina abstract we advocate a dynamic factor model to provide alternative measures of output data using indirect information from economic indicators we apply the method to show evidence of a significant gap between estimated and official measures of argentine gdp since 2007

energy use in a transitional economy the case of poland abstract this paper provides a sectoral analysis of how energy use has changed in poland since the 1970s with particular emphasis on changes since the country began its transition from a centrally planned to a market economy in 1990 total final energy use in 1991 was 25 below that in 1988 and the lowest since the mid 1970s the most important factors behind the large decline in polish energy use in 1990 were a sharp fall in industrial output and a huge drop in residential coal use driven by higher prices energy use declined by only 2 in 1991 which was less than the fall in gdp of 8 key factors that lessened the decrease in energy use after 1989 were a rise in energy intensity in many heavy industries and a shift toward greater use of cars and trucks in passenger and freight transport higher energy prices have had an evident impact on residential coal use but in industry there was relatively little sign of energy conservation in 1991

manufacturing energy use in eight oecd countries decomposing the impacts of changes in output industry structure and energy intensity this paper examines trends in manufacturing energy use in eight oecd countries decomposing the changes that occured between 1973 and 1987 into the effects of changes in aggregate manufacturing activity industry structure and energy intensities measured at the industry group level while manufacturing production grew in every country except the uk the rate of growth was variable from nation to nation structural change led to modest reductions in energy use in most countries although in norway structural change led to substantial growth in energy use the reduction in energy intensities was strikingly uniform across all nations ranging from 20 norway to 36 japan over the period of the analysis while other studies have used divisia decomposition techniques we use an alternative method based on laspeyres indices a comparison of the two techniques shows that they yield closely similar empirical results although the laspeyres approach is more easily interpreted while the interactions between changes in structure and intensity are arbitrarily assigned to the two factors by the divisia approach the lapeyres method yields interaction terms that explicitly account for such effects
