interfuel substitution biomass consumption economic growth and sustainable development evidence from brazil abstract this paper examines the possibilities of substituting the fossil fuels including natural gas coal and oil for biomass consumption in brazil for the period 1980 2015 we used the ridge regression procedure to generate the parameter estimates from a second order taylor series approximation of log linear trans log specification for robustness sake we constructed an index of sustainable development sd as additional regressand alongside the conventional gross domestic product gdp overall the results show strong evidence of substitution possibilities between biomass and the fossil fuels in both the gdp and the sd models indicating that brazil can continue with its growth and sustainability agenda by using more biomass and less fossil fuels the results also show that the sd model gives a more robust output elasticity estimates as it detects the inherent negative effect of some of the fossil fuels on the economy that are not directly observable in the gdp model

bounds testing approach to analyzing the environment kuznets curve hypothesis with structural beaks the role of biomass energy consumption in the united states abstract this paper re examines the specification of the environmental kuznets curve ekc for the us economy by accounting for the presence of a major renewable energy source and trade openness over the period 1960 2016 biomass energy consumption and trade openness as well as oil prices are considered as additional determinants of economic growth and consequentially of co 2 emissions the bounds testing approach to cointegration is used to examine the long run relationship between the variables in the presence of structural breaks the causal relationship between the variables is investigated by applying the vecm granger causality test and accommodating structural breaks the results confirm the presence of cointegration between the variables moreover the relationship between economic growth and co 2 emissions is not only inverted u shaped but also n shaped in the presence of structural breaks and biomass biomass energy consumption lowers co 2 emissions exports imports and trade openness are also environment friendly the causality analysis underscores a feedback effect between biomass energy consumption and co 2 emissions economic growth still granger causes co 2 emissions in this new setup

entry stackelberg equilibrium and reasonable conjectures we show that the consideration of stackelberg equilibrium and reasonable conjecture equilibria r c e provide some foundation to the concept of limit pricing

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

overall review of the overcapacity situation of china s thermal power industry status quo policy analysis and suggestions abstract china s thermal power industry has gone through the phases of rapid development in the last decade but the excessive enthusiasm of thermal power investment is making this industry overcapacity the unbalanced demand supply relationship in electric power market greatly affects the economic benefit of most thermal power plants in this paper we give an overall review of the overcapacity situation of china s thermal power industry which is supported by latest data then policy orientation and its effect is discussed it can be found out that policies on the respect of construction scale control renewable power integration feed in tariff reduction and environmental protection were considered as the main solution to relieve the over capacity situation finally we propose three suggestions for the future development of china s thermal industry

the asymmetric granger causality analysis between energy consumption and income in the united states abstract we investigated granger causality between variants of the energy consumption sources and gross domestic product gdp for the united state of america usa to accomplish this objective we utilized a recent approach of asymmetric granger causality developed by hatemi j for the period january 1973 october 2011 our results indicated presence of asymmetric granger causality between a few variants of energy consumption sources i e coal consumption cc natural gas consumption ng primary energy consumption pe and total renewable energy consumption tre and gdp all measured in growth rates additionally when positive shocks are analyzed we found the evidence of unidirectional granger causality running from gdp growth rate to growth rate of cc and from growth rate of total electricity end use ec to gdp growth rate additionally we find significant evidence of bidirectional granger causality between ng and gdp pe and gdp and tre and gdp all measured in growth rates however in case of negative shocks we find that the null hypothesis that growth rates in cc and tre do not granger cause gdp growth rate is rejected at 5 level of significance these results have important implications for research analysts as well as policy makers of the usa economy

decoupling economic growth from carbon dioxide emissions in china a sectoral factor decomposition analysis china is facing the dilemma of how to coordinate economic development and carbon dioxide co2 emissions reduction this paper investigates the decoupling effect of economic growth from co2 emissions in china during the period 1992 2012 using the logarithmic mean divisia index lmdi method we decompose the driving forces of the decoupling of economic growth from co2 emissions in china s five major economic sectors into several factors and measure the contribution of each factor to the decoupling of china s overall economy from co2 emissions the results show that china performed the weak decoupling of economic growth from co2 emissions during 1992 2012 and so did all its five major sectors such a state did not occur smoothly and presented five different stages energy intensity and economic activity level were the most important factors affecting the decoupling in china energy intensity decreased in all sectors indicating a large acceleration for the sectoral decoupling states this finding is applicable to process carbon intensity in industrial sector and energy emission factor in agricultural industrial construction and service sectors in terms of sectoral effects on the decoupling in china industrial sector played a dominant role while construction sector had the most marginal influence the economic activity level and economic share of industrial sector exerted the most negative effects on the decoupling the energy intensity of industrial sector played a key role in promoting the national decoupling state while the energy emission factor of agricultural sector contributed the least

decoupling co2 emissions and industrial growth in china over 1993 2013 the role of investment abstract since industrial sector is a leading energy consumer and co 2 emitter in china the degree of the decoupling of co 2 emissions and industrial growth plays a critical role in realizing the energy conservation and emission reduction goals of china this is the first study to present a specific investigation on the decoupling of co 2 emissions and industrial growth in china from 1993 to 2013 using an extended logarithmic mean divisia index lmdi model focusing on both energy related and process related co 2 emissions and introducing three novel investment factors i e investment scale investment share and investment efficiency we highlight and explore the remarkable role of investment in the mitigation and decoupling of co 2 emissions with industrial growth the results show that china s industrial sector experienced the weak decoupling during 1993 2013 the investment scale is the most important factor responsible for the increase in co 2 emissions and the inhibition of the decoupling the investment efficiency effect has a volatile trend and overall it plays the most significant role in reducing co 2 emissions followed by the energy intensity effect and process carbon intensity effect whereas the energy mix carbon coefficient and investment share have marginal effects among 36 industrial sub sectors the seven factors of rcmcp raw chemical materials and chemical products nmp nonmetal mineral products and spfm smelting and pressing of ferrous metals have significant effects on the decoupling thus the three sub sectors should be among the top concerns for abating co 2 emissions finally we provide policy recommendations considering both conventional and investment factors for china s industrial sector to realize emission reduction targets

explaining the non causality between energy and economic growth in the u s a multivariate sectoral analysis the rapidly growing literature on the relationship between energy consumption and economic growth has not univocally identified the causal relationship yet we argue that bivariate models which analyze the causality only at the macro level are eventually misleading especially in cases where both variables do not cover the same scope of economic activity after discussing appropriate pairs of variables we investigate granger causality between energy and growth in the u s for the period from 1970 to 2007 for three sectors industry commercial sector transport as well as on the macro level using the recently developed ardl bounds testing approach by pesaran and shin 1999 and pesaran et al 2001 we find evidence for unidirectional long run granger causality in the commercial sector from growth to energy as well as evidence for bi directional long run granger causality in the transport sector the dependence of causality on the level of aggregation is interpreted as evidence for simpsons paradox the choice of control variables is based on findings from the environmental kuznets curve literature we find that controlling for the increasing energy productivity of production as well as trade significantly improves the fit of the bivariate model

nuclear energy consumption and economic growth in nine developed countries this article attempts to test the causal relationship between nuclear energy consumption and real gdp for nine developed countries for the period 1971 2005 by including capital and labour as additional variables using a modified version of the granger causality test developed by toda and yamamoto 1995 we found a unidirectional causality running from nuclear energy consumption to economic growth in japan netherlands and switzerland the opposite uni directional causality running from economic growth to nuclear energy consumption in canada and sweden and a bi directional causality running between economic growth and nuclear energy consumption in france spain the united kingdom and the united states in spain the united kingdom and the usa increases in nuclear energy consumption caused increases in economic growth implying that conservation measures taken that reduce nuclear energy consumption may negatively affect economic growth in france japan netherlands and switzerland increases in nuclear energy consumption caused decreases in economic growth suggesting that energy conservation measure taken that reduce nuclear energy consumption may help to mitigate the adverse effects of nuclear energy consumption on economic growth in canada and sweden energy conservation measures affecting nuclear energy consumption may not harm economic growth

economic growth and energy consumption causal nexus viewed through a bootstrap rolling window one puzzling results in the literature on energy consumption economic growth causality is the variability of results particularly across sample periods sample sizes and model specification in order overcome these issues this paper analyzes the causal links between energy consumption and economic growth for g 7 countries using bootstrap granger non causality tests with fixed size rolling subsamples the data used includes annual total energy consumption and real gross domestic product gdp series from 1960 to 2006 for g 7 countries excluding germany for which the sample period starts from 1971 using the full sample bootstrap granger causality test we find that there is predictive power from energy consumption to economic growth only for canada however parameter instability tests show that none of the estimated models have constant parameters and hence the full sample results are not reliable analogous to the full sample results the results obtained from the bootstrap rolling window estimation indicate no consistent causal links between energy consumption and economic growth we however find that causal links are present between the series in various subsamples furthermore these subsample periods correspond to significant economic events indicating that the findings are not statistical artefacts but correspond to real economic changes our results encompass previous findings and offer an explanation to varying findings

a multiscale reassessment of the environmental kuznets curve for energy and co2 emissions abstract this paper investigates the environmental kuznets curve hypothesis for total primary energy supply and co2 from fuel combustion over the period 1971 2015 our analysis has two distinguishing features firstly it adopts a robustness approach by a using both parametric and semi parametric methods and b analysing different geographical scales secondly it strictly adheres to the ekc narrative by a not using control variables and b taking energy and co2 in absolute rather than in per capita terms which is consistent with the fact that nature cares about absolute pressures we show how evidence for ekc changes depending on the model specification the sample and the used variables hence this paper contributes to explaining why the literature on the ekc gives mixed results the multiscale perspective and some theoretical considerations however tell how to perform the analysis appropriately thus we can affirm that both for co2 and energy the fragile evidence of ekc that was emerging at the end of the last century has vanished with the new wave of globalization there is only evidence of decreasing elasticities for very high income countries interestingly the great recession might have produced structural reductions in tpes and co2 in the affected countries finally the case of germany which shows ekc patterns indicates that active energy policies can reduce energy and co2 without harming the economy

the growth of income and energy consumption in six developing countries this paper reexamines the inter temporal link between energy consumption and income in six developing countries with diverse economic backgrounds and energy statistics in a production function framework we employ the generalized variance decompositions and generalized impulse response techniques to see if the growth of income and energy consumption contains considerable information to predict each other in all countries energy appears as an essential factor of production results indicate that energy may be a relatively more important input than labor and or capital in some countries hence neutrality of energy does not seem to hold

renewable energy oil prices and economic activity a granger causality in quantiles analysis this paper analyzes the causal relationship between renewable energy consumption oil prices and economic activity in the united states from july 1989 to july 2016 considering all quantiles of the distribution although the concept of granger causality is defined for the conditional distribution the majority of papers have tested granger causality using conditional mean regression models in which the causal relations are linear we apply a granger causality in quantiles analysis that evaluates causal relations in each quantile of the distribution under this approach we can discriminate between causality affecting the median and the tails of the conditional distribution we find evidence of bi directional causality between changes in renewable energy consumption and economic growth at the lowest tail of the distribution besides changes in renewable energy consumption lead economic growth at the highest tail of the distribution our results also support the unidirectional causality from fluctuations in oil prices to economic growth at the extreme quantiles of the distribution finally we find evidence of lower tail dependence from changes in oil prices to changes in renewable energy consumption our findings call for government policies aimed at developing renewable energy markets to increase energy efficiency in the u s

determinants of co2 emissions in a small open economy abstract the aim of the paper is to explore the relationship between economic development and carbon dioxide co2 emissions for a small open and industrialized country austria we test whether an environmental kuznets curve relationship also holds for a single country rather than concentrating on panel or cross section data for a set of countries a cubic i e n shaped relationship between gdp and co2 emissions is found to fit the data most appropriately for the period 1960 1999 and a structural break is identified in the mid seventies due to the oil price shock furthermore two variables are additionally significant import shares reflecting the well known pollution haven hypothesis and the share of the tertiary service sector of total production gdp accounting for structural changes in the economy emission projections derived from this single country specification support the widely held opinion that significant policy changes are asked for when implementing the kyoto protocol in order to bring about a downturn in future carbon emissions

an alternative analysis of apparent ekc type transitions abstract the hypothesis of the environmental kuznets curve ekc depends upon the assumption that countries pass through a similar environmental impact trajectory as they experience income growth implying that income levels determine pollution levels the authors present evidence that this is not representative of the way many individual country s pollution emission trajectories evolve and question the emphasis on income determinism by the ekc the study proposes that nonlinear dynamic systems analysis provides a more complete description of individual country pollution trajectories in the case of co 2 emissions the nonlinear time trajectories show abrupt transitions that occur contemporaneously with historical events and over a broad range of incomes

the response of the beijing carbon emissions allowance price bjc to macroeconomic and energy price indices in 2013 china opened pilot carbon emission trading markets in seven provinces where carbon emission allowances have now been traded for more than two years in this paper we employ a structural var model and the price of the beijing carbon emission allowance to study the dynamic relationships among the price of the carbon emission allowance economic development and the price of energy this paper s data cover the period from april 2 2014 to november 6 2015 this paper provides information that will be helpful to both investors and governmental policy makers the results show that 1 an increase of one standard deviation in the coal price leads to an initial increase of approximately 0 1 in the beijing carbon price after 2 days there is a decrease of less than 0 1 and the price gradually increases by approximately 0 1 after 30 days 2 the price of the beijing carbon emission allowance is mainly affected by its own historical price 3 the beijing carbon emission allowance price crude oil price natural gas price and economic development have positive albeit non significant correlations

housing wealth and residential energy consumption abstract the housing wealth effect often manifests as a positive relationship between consumption and perceived housing wealth e g the perceived value of houses when the perceived value of a property rises homeowners may feel more comfortable and secure about their wealth causing them to spend more this study adopts a behavioural approach to verify if this relationship holds true for residential energy consumption in the uk while controlling for property characteristics and a large number of demographic socioeconomic and energy use behaviour variables we identified a significant relationship between housing wealth and energy consumption our models also considered psychological biases in energy consumption behaviours such as the framing effect our findings shed light on the behavioural aspects of housing wealth effect on residential energy consumption and demonstrate the potential to nudge households towards energy conservation most importantly we provide empirical evidence on the intriguing relationship among housing wealth residential energy consumption and fuel poverty the findings of this study are particularly helpful in designing and implementing energy consumption policies that can strike a balance between social justice and economic efficiency

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

does energy price regulation benefit china s economy and environment evidence from energy price distortions abstract china s energy prices have long been regulated due to the critical role energy plays in economic growth and social development which leads to energy price distortion to some extent to figure out whether energy price regulations will benefit china s economy measured by gdp growth and environment measured by carbon emissions we conducted an in depth simulation using path analysis where five energy products natural gas gasoline fuel oil steam coal and coking coal are selected and three measurements absolute relative and moving of energy price distortions are calculated the results indicate that with a series of energy pricing policies the price distortion for a single type of energy has gradually transformed while the energy pricing system in china is not fully market oriented yet furthermore china s economy benefits from relative and moving distortions while the absolute distortions of energy prices have negative impacts on economic growth finally with regard to the environment carbon emissions call for fewer distortions

electrical energy usage over the business cycle causality from macroeconomic conditions to electrical usage overall and in the residential commercial industrial and other sectors is examined the paper shows that changes in macroeconomic conditions cause significant changes in electrical usage in the commercial and industrial sectors and overall in addition the paper shows that causality occurs at business cycle frequencies and that there are asymmetries over the business cycle an implication is that forecasts used to assess the probability of exceeding capacity constraints should incorporate forecasts of macroeconomic conditions asymmetries over the cycle and how the commercial and industrial sectors will respond to such changes

the role of renewable energy to validate dynamic interaction between co2 emissions and gdp toward sustainable development in malaysia abstract closing the gap between economy activity and environmental quality is one of the solutions for reaching sustainable development in malaysia to do so the cubic polynomial functional form of ekc is utilized by accommodating renewable energy into the base of the ekc model and validating its hypothesis between co 2 emissions and gdp growth for the 1971 2015 period the f bounds vecm granger causality cusum and cusumsq tests are utilized the estimated results consistently show that the inverted n shaped ekc hypothesis holds in malaysia ceteris paribus the co 2 emissions will be declined when the gdp reach rm2841 9 billion in 2030 which is beyond the sample period the renewable energy has a negative significant effect on co 2 emissions and the direction of causality is running from co 2 emissions to renewable energy also the gdp growth will be the remedy for environmental pollution problems and that renewable energy is one of important elements to be considered for improving environmental quality a tighter and concentrated environmental policy is needed to direct the environment economic growth nexus toward a downward trend consequently these results may help malaysian policymakers to establish an energy policy that guarantees a balance between economic growth and environmental prosperity

foreign direct investment co2 emissions nexus in middle east and north african countries importance of biomass energy consumption abstract this study examines the association between foreign direct investment fdi and carbon emissions for the middle east and north african mena region in 1990 2015 including biomass energy consumption as an additional determinant of carbon emissions we apply the generalized method of moments gmm to validate the existence of the pollution haven hypothesis phh the n shaped association is also validated between fdi and carbon emissions the link between economic growth and carbon emissions is inverted u and n shaped that is it satisfies the environmental kuznets curve ekc hypotheses biomass energy use lowers carbon emissions and the causality analysis reveals that fdi causes co2 emissions clearly the results confirm the existence of a feedback effect between economic growth and carbon emissions the connection between biomass energy use and co2 emissions is also bidirectional the empirical findings suggest policy makers to design comprehensive trade and energy policies by targeting the cleaner production practices for not only to ensure environmental sustainability but also to fulfil the objectives of sustainable development goals

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

decomposition of ireland s carbon emissions from 1990 to 2010 an extended kaya identity in recent decades ireland has been an important example of a development pathway where rapid economic growth was accompanied by rising energy demand and increasing carbon emissions understanding the driving forces of carbon emissions is necessary for policy formulation and decomposition analysis is widely used for this purpose this study uses an extended kaya identity as the scheme and applies the log mean divisia index lmdi i as the decomposition technique change in carbon emissions is decomposed from 1990 to 2010 and includes a measure of the effect of renewable energy penetration results illustrate that scale effects of affluence and population growth act to increase emissions and are countered primarily by energy intensity and fossil fuel substitution renewable energy penetration has a minor effect but has been increasing in recent years policy will need to significantly reduce intensity and increase renewables if applicable targets are to be reached this requires not only a comprehensive suite of policies and measures but emphasis on the development path and non technical change for optimal outcomes

environmental degradation in france the effects of fdi financial development and energy innovations abstract this paper explores the determinants of carbon emissions in france by accounting for the significant role played by foreign direct investment fdi financial development economic growth energy consumption and energy research innovations in influencing co 2 emissions function in this endeavour we employ the novel sor shahbaz et al 2017 unit root test on french time series data over the period 1955 2016 to examine the order of integration in the presence of sharp and smooth structural breaks in the variables we also apply the bootstrapping bounds testing approach recently developed by mcnown et al 2018 to investigate the presence of cointegration and the empirical findings underscore the presence of cointegration among the time series moreover we find that fdi has a positive impact while energy research innovations have a negative impact on french carbon emissions financial development lowers carbon emissions thereby improving the french environmental quality fdi degrades the environment and thus supports the pollution haven hypothesis in france similarly financial development suggests that financial stability is a required condition for improving environmental quality so are energy research innovations contrarily energy consumption is positively linked with carbon emissions however the relationship between economic growth and co 2 emissions is an inverted u which is a validation of the environmental kuznets curve ekc

economic growth and energy consumption revisited evidence from linear and nonlinear granger causality the relationship between energy consumption and economic growth is considered as an imperative issue in energy economics previous studies have ignored the nonlinear behavior which could be caused by structural breaks in this study both linear and nonlinear granger causality tests are applied to examine the causal relationship between energy consumption and economic growth for a sample of asian newly industrialized countries as well as the u s this study finds evidence supporting a neutrality hypothesis for the united states thailand and south korea however empirical evidence on philippines and singapore reveals a unidirectional causality running from economic growth to energy consumption while energy consumption may have affected economic growth for taiwan hong kong malaysia and indonesia policy implications are also discussed

decomposition of aggregate energy intensity changes in two measures ratio and difference decomposition analysis has been popular in energy demand analysis and has been found useful in policy related studies past studies include decomposition of changes of an aggregate indicator measured in terms of either ratios or differences into several pre defined contributing factors aggregate indicators that are often studied include total national energy demand energy demand in specific consuming sectors aggregate energy intensity and energy related carbon dioxide emissions however the possible linkages between the ratio measure and the difference measure including their decomposition results have seldom been analysed this paper examines this issue using the divisia decomposition technique and a unique pair of decomposition formulae numerical examples based on singapore and taiwan industrial electricity demand data are presented

decomposition of carbon intensity in electricity production technological innovation and structural adjustment in china s power sector abstract china s power generation accounted for 24 of the world s total output ranking first in 2015 as a suitable performance indicator carbon intensity of electricity reflects a variation in the average level of carbon emissions per unit of electricity generated as the largest carbon emitter among various industries power sector is in duty bound to reduce carbon emissions and achieve sustainable development great progress has been made in china s power sector which is reflected by the effects of technological innovation and structural adjustment with logarithm transformation and integral transformation three dimensional decomposition model is proposed to quantitatively measure the changed carbon intensity of electricity due to technological innovation and structural adjustment in the context of three dimensional model the variation of carbon intensity can be decomposed into absolute changes and or relative changes furthermore accumulative decomposition results are obtained by chain linked calculation rules finally the proposed models are implemented in china s power industry to reveal its historical progress during 1980 2014 some important conclusions are also found based on the decomposition results

analysis of thermal coal pricing and the coal price distortion in china from the perspective of market forces abstract the price of thermal coal has always been the focus of the debate between coal mining industry and electric power industry the thermal coal price is always lower than other same quality coal and this phenomenon of thermal coal price distortion has been existing in china for a long time the distortion coal price can not reflect the external cost and the resource scarcity of coal which could result in environment deteriorating and inefficient resource allocation this paper studied the phenomenon of thermal coal price distortion through economic theoretical modeling and empirical cointegration analysis from the perspective of market forces the results show that thermal coal price is determined by electricity price the prediction elasticity of a electricity enterprise price elasticity of demand of electricity the input prediction elasticity of a electricity enterprise and the price elasticity of supply of thermal coal the main reason of coal price distortion is the unbalance market force of coal industry and thermal coal generation industry the distortion rate of coal price is positively related to the market force of electric power industry and negatively related to the industrial concentration of coal industry

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 consumption and economic growth in the usa evidence from renewable energy abstract recent debates about renewable energy consumption manifest two main expectations firstly renewable energy consumption should contribute to economic growth and secondly it should not cause damage on environment this study focuses on the first issue by applying toda yamamoto procedure and bootstrap corrected causality test for the us since empirical literature criticizes the toda yamamoto test which bases on asymptotic distribution the models consist of real gdp employment investment and kinds of renewable energy consumption only one causal relationship was found from biomass waste derived energy consumption to real gdp no causal relationship was found between real gdp and all of the other renewable energy kinds total renewable energy consumption geothermal energy consumption hydro electric energy consumption biomass energy consumption and biomass wood derived energy consumption that is using of energy from waste cause not only solving the dumping problems but also it contributes to real gdp for policy purpose the results of this study suggest that countries should concentrate on energy producing from waste as an alternative energy resource

the environmental kuznets curve does one size fit all abstract this paper uses a new panel data set on state level sulfur dioxide and nitrogen oxide emissions from 1929 1994 to test the appropriateness of the one size fits all reduced form regression approach commonly used in the environmental kuznets curve literature empirical results provide initial evidence that an inverted u shape characterizes the relationship between per capita emissions and per capita incomes at the state level parameter estimates suggest however that previous studies which restrict cross sections to undergo identical experiences over time may be presenting statistically biased results

hidden regimes and the demand for carbon dioxide from motor gasoline abstract perhaps the most tactile source of anthropogenic carbon dioxide co2 emissions stem from vehicle use because consumers are well aware of their price and quantity decisions it is likely that consumer demand for co2 emissions from motor gasoline are quite responsive to the overall state of the economy using a structurally identified markov switching demand model i find that co2 emissions respond asymmetrically to changes in income and the price of gasoline in expansionary and contracting states of the economy the findings of this paper indicate that flexible policy instruments have the potential to mitigate undue burden on consumers and producers compared to their static counterparts

nuclear energy consumption oil prices and economic growth evidence from highly industrialized countries this study utilizes the johansen cointegration technique the granger non causality test of toda and yamamoto 1995 the generalized impulse response function and the generalized forecast error variance decomposition to examine the dynamic interrelationship among nuclear energy consumption real oil price oil consumption and real income in six highly industrialized countries for the period 1965 2008 our empirical results indicate that the relationships between nuclear energy consumption and oil are as substitutes in the u s and canada while they are complementary in france japan and the u k second the long run income elasticity of nuclear energy is larger than one indicating that nuclear energy is a luxury good third the results of the granger causality test find evidence of unidirectional causality running from real income to nuclear energy consumption in japan a bidirectional relationship appears in canada germany and the u k while no causality exists in france and the u s we also find evidence of causality running from real oil price to nuclear energy consumption except for the u s and causality running from oil consumption to nuclear energy consumption in canada japan and the u k suggesting that changes in price and consumption of oil influence nuclear energy consumption finally the results observe transitory initial impacts of innovations in real income and oil consumption on nuclear energy consumption in the long run the impact of real oil price is relatively larger compared with that of real income on nuclear energy consumption in canada germany japan and the u s

a spatial panel data approach to estimating u s state level energy emissions we take advantage of a long panel data set to estimate the relationship between u s state level carbon dioxide co2 emissions economic activity and other factors we specify a reduced form energy demand model to account for energy consumption activities that drive energy related emissions we contribute to the literature by exploring several spatial panel data models to account for spatial dependence between states estimation results and rigorous diagnostic analysis suggest that 1 economic distance plays a role in intra and inter state co2 emissions and 2 there are statistically significant positive economic spillovers and negative price spillovers to state level emissions

renewable energy policies and contradictions in causality a case of next 11 countries abstract numerous studies on the causal relationship between economic growth energy consumption and carbon dioxide co2 emissions have shown divergence in policy recommendations which arises mainly due to the choice of methodology and the period of study this inconclusiveness in policy prescriptions might turn out to be critical when the renewable energy policies of the developing nations are considered our study analyses the causal relationship between economic growth carbon emissions fossil fuel and renewable energy consumption in next 11 countries during the period of 1990 2016 along with conducting parametric and non parametric causality tests together introducing the geweke 1982 causality test in the literature of energy economics we attempt to establish a wholesome aspect of policy design by comparing and complementing results of different causality analysis and how the causality directions should comply with the context setting our empirical evidence confirms that robust renewable energy policy can be designed by complementing the various causality test results rather than focusing on one particular causality test

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems

carbon intensity of electricity in asean drivers performance and outlook abstract the association of southeast asian nations asean with its ten member countries has a total population exceeding 600 million its energy related co2 emissions have been growing and in 2013 amounted to 3 6 of total global emissions about 40 of asean s energy related co2 emissions are currently attributable to electricity production in view of this high share we study the co2 emissions of asean s electricity production sector with a focus on the aggregate emission intensity aci given by the level of co2 emissions for each unit of electricity produced drivers of aci are analysed for individual countries and spatial analysis is conducted by comparing factors contributing to differences between the acis of individual countries and that of the asean average arising from these analyses and in light of the current developments it is concluded that drastic actions need to be taken both at the national and regional levels in order to reduce growth in the region s electricity related co2 emissions two key policy issues namely overcoming national circumstances to improve electricity generation mix and improving power generation efficiency are further discussed

carbon emission intensity in electricity production a global analysis we study changes in the aggregate carbon intensity aci for electricity at the global and country levels the aci is defined as the energy related co2 emissions in electricity production divided by the electricity produced it is a performance indicator since a decrease in its value is a desirable outcome from the environmental and climate change viewpoints from 1990 to 2013 the aci computed at the global level decreased only marginally however fairly substantial decreases were observed in many countries this apparent anomaly arises from a geographical shift in global electricity production with countries having a high aci increasingly taking up a larger electricity production share it is found that globally and in most major electricity producing countries reduction in their aci was due mainly to improvements in the thermal efficiency of electricity generation rather than to fuel switching estimates of the above mentioned effects are made using lmdi decomposition analysis our study reveals several challenges in reducing global co2 emissions from the electricity production sector although technically the reduction potential for the sector is known to be great

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
