Growing climate change concerns have intensified the focus on agribusiness sustainability,driving an urgent energy transition to improve production efficiency and mitigate environmental harm.The complex interplay between energy efficiency and energy consumption highlights the essential role of strategic energy policies in ensuring sustainable development.This study used the Double-Log regression model with bootstrap resampling to examine the rebound effect in the energy transition of agribusiness focusing on five Latin American countries including Brazil,Argentina,Uruguay,Colombia,and Mexico based on the agricultural sector data during 2010–2022.The findings revealed that the rebound effect significantly influences energy transition,with varying degrees of impact across agricultural sectors.This study identified partial rebound effect across all five countries,with elasticity coefficient varying from 9.63%(Colombia’s coffee sector)to 89.12%(Brazil’s livestock sector).In Brazil’s sugarcane sector,nonrenewable energy,agricultural employment,and irrigation efficiency were identified as key factors influencing energy consumption,while in livestock sector,energy consumption was affected by CH_(4)emissions,income and well-being of farmers,water consumption,and water conservation practices.In Mexico’s livestock sector,CH_(4)emissions,nonrenewable energy,and water conservation practices were the key factors affecting energy consumption.In Argentina’s sugarcane sector,pesticides,NO_(2)emissions,renewable energy,and agricultural employment were the key factors affecting energy consumption,while renewable energy,income and well-being of farmers,and water consumption were the key factors affecting energy consumption in livestock sector.In Uruguay’s livestock sector,non-renewable energy,income and well-being of farmers,and irrigation efficiency were the key factors affecting energy consumption.In Colombia’coffee sector,NO_(2)emissions and irrigation efficiency were identified as key factors influencing energy consumption.Finally,this study reinforces the importance of aligning energy transition with Sustainable Development Goals(SDGs),ensuring that energy efficiency gains do not inadvertently increase energy consumption or environmental degradation. 展开更多

Rebound effect derived from energy efficiency improvement has been widely invested.However,most of studies focus on the rebound effect of the energy composite level and neither distinguish nor compare different energy types.We compare the differences in energy saving and energy rebound between primary and secondary energy sources,and further decompose the rebound effect into production rebound part and final demand component.To do so,we add a module for rebound into a comparative state China-CGE model.We design and test two simulation scenarios using the model.In Scenario 1,all production sectors' energy efficiency of using primary energy increases by 5%.In Scenario 2,all production sectors' energy efficiency of using secondary energy increases by 5%.The results show that Scenario 2 leads to more GDP growth and more energy saving.Our scenarios show rebound effects range between 9.6% and 27.9%,and in general are higher when energy efficiency of using primary energy sources is improved.Our decomposition analysis shows that improving energy efficiency in production sectors would stimulates energy use of final demand.Indeed,the consumption side has significant contribution to rebound in secondary energy use,especially in crude oil and gas.This study reveals that improving efficiency of using secondary energy is better than improving that of primary energy,both in terms of economic impact and energy rebound.And complementary policies that prevent energy services prices from falling too much can be adopted to reduce rebound.Controlling residential energy use could also be effective in reducing rebound,this has particular implication to economies in which residential energy consumption are far from saturation. 展开更多

This study summarizes energy efficiency policy and programs in general and in Turkey. Also it gives defination of the “rebound effect” concept. The rebound effect is related to consumer’s tendency to consume more energy due to economic benefit from efficiency improvement. The ‘rebound effect’ is the focus of a long-running dispute of energy economics but it is very new concept in the most developing countries. In literature according to some economist gains in energy efficiency will also reduce the real per unit price of energy services and hence the consumption of energy will rise and partially offset the initial reduction in the usage of energy sources. However for others size of the rebound effect is too small to take attention. The empirical literature shows that the size of rebound effect can change from country to country and sector to sector. 展开更多

The two essential terms in environmental sciences-dematerialization and decoupling-have always been controversial. This study aims to trace the evolution path on the methodologies, the evidences and the policies, and to reflect on the implications of the development. We specifically present several classical definitions so as to summarize the similarities and differences thereinafter. Several commonly used methodologies, which are employed for evaluating the levels of dematerialization and decoupling, are discussed. As expected, the empirical evidences rarely support the absolute dematerialization and decoupling, which challenge the relevant policies implemented worldwide. In this context, the rebound effect, which is regarded as the main obstacle, is necessary to be examined in the various sectors and areas. However, the results of the rebound levels are far from unanimous. This article has a further discussion on the possible direction for the inconclusive debate in a broader perspective. 展开更多

Under the emerging trend of the new power systems,enhancing the energy flexibility of air conditioning loads to promote electricity demand response is crucial for regulating the real-time balance.As a typical temperature-controlled loads,air conditioning loads can generate rebound effect when participating in demand response,resulting in sudden load increases and posing risks to grid security.However,the existing research mainly focuses on the energy flexibility,which leads to an imperfect demand response mechanism and thus affects the optimal scheduling strategy.Therefore,the study proposes a comprehensive quantification method in view of rebound effect for the demand response performance of air conditioning loads,by using probability distribution,Latin hypercube sampling,Monte Carlo simulation,and scenario analysis methods.The demand response event was divided into response phase and recovery phase,and by considering energy flexibility during the response phase and rebound effect during the recovery phase,three dimensionless evaluation indexes for comprehensive demand response performance were constructed.Using this quantification method,the impact patterns of three types of random variables were compared,including meteorological,design variables,and control variables.Additionally,considering the differences in building types(office and hotel buildings)and building capacities(small,medium,and large),the effectiveness of air conditioning load participation in demand response measures in different building application scenarios was explored.The results show that the influence of the design variables on the response performance is less than that of the control variables,but significant,reaching 45%compared to the control variables.Moreover,the influence varies with building type,capacity and climate zone,and building demand response design has more potential in the following scenarios:the cold climate,the hot summer and cold winter climate,the medium building and the hotel building. 展开更多

Following the Paris Agreement,economic development demands energy services while reducing emissions.This study focuses on non-residential natural gas consumption,which plays a crucial role in the energy transition;however,market-based mechanisms are still in the early stages and have not yet been explored.Based on the analysis of data collected from 2000 to 2020 in China,this study constructs a simultaneous equation model to analyze the rebound and induced effects of non-residential natural gas consumption.This paper finds that industrial economic growth has a significant promoting effect on nonresidential gas consumption.In addition,implementing and promoting natural gas utilization policies and increases in natural gas price can significantly reduce gas consumption intensity.This article innovatively calculates the rebound and induced effects of nonresidential gas consumption,providing a decision-making reference for accelerating the realization of the dual-carbon goal. 展开更多

Energy use is becoming more efficient due to technological innovations.We focused on the transportation sector in China to develop a national multisector computable general equilibrium(CGE)model for analyzing the rebound effect from an improvement of 10%in the energy efficiency.We compared the size of the energy rebound effect at both the macroeconomic and sectoral levels in different transportation modal subsectors,namely rail,road,water,and air travel.The findings showed that the magnitude of the rebound effect varies across the transportation modes.This is particularly true for the air transportation sector,which has an economy-wide rebound effect of 30.1%and an own-sector rebound effect of 74.6%because of a sharp increase in the export demand for air transport services.We also quantitatively evaluated the contribution of energy efficiency improvement in the transportation sector to China’s economic growth and carbon reductions and found a positive dividend effect on the economy as well as the environment.The modeling results suggest that improving overall transportation energy efficiency by 10%generates an economy-wide welfare gain of approximately 29 billion yuan,while 19 billion yuan are attributable to a more efficient road transportation subsector.Furthermore,to offset the effects of these mode-specific rebound effects,we simulated the effectiveness of different policies and solutions.These included economic instruments in the form of energy,environmental,and carbon taxes,household transport consumption structure adjustments,and energy structure adjustments.This study revealed that combining these sustainable development policies offers opportunities for economy-wide multisectoral improvements in energy savings,emissions reduction,and economic benefits. 展开更多

The enhancement of energy efficiency stands as the principal avenue for attaining energy conservation and emissions reduction objectives within the realm of road transportation.Nevertheless,it is imperative to acknowledge that these objectives may,in part or in entirety,be offset by the phenomenon known as the energy rebound effect(ERE).To quantify the long-term EREs and short-term EREs specific to China’s road transportation,this study employed panel cointegration and panel error correction models,accounting for asymmetric price effects.The findings reveal the following:The long-term EREs observed in road passenger transportation and road freight transportation range from 13%to 25%and 14%to 48%,respectively;in contrast,the short-term EREs in road passenger transportation and road freight transportation span from 36%to 41%and 3.9%to 32%,respectively.It is noteworthy that the EREs associated with road passenger transportation and road freight transportation represent a partial rebound effect,falling short of reaching the magnitude of a counterproductive backfire effect.This leads to the inference that the upsurge in energy consumption within the road transportation sector cannot be solely attributed to advancements in energy efficiency.Instead,various factors,including income levels,the scale of commodity trade,and industrial structure,exert more substantial facilitating influences.Furthermore,the escalation of fuel prices fails to dampen the demand for energy services,whether in the domain of road passenger transportation or road freight transportation.In light of these conclusions,recommendations are proffered for the formulation of energy efficiency policies pertinent to road transportation. 展开更多

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