“…Their main finding was that the effect of income on energy demand for transportation was larger than the effect of energy prices. In addition, Solís and Sheinbaum [36] evaluated the trends of energy consumption and CO 2 emissions in the transportation sector in 1990-2010. They found that the increase of private vehicles and light truck transport were the main factors driving up the energy demand and emissions of the sector.…”

Abstract:The analysis of useful exergy (UE), which is the minimum amount of work required to produce a given end-use, provides insights on the relationships between structural changes and energy transitions because it focuses on what energy is used for, i.e., energy services, rather than where it comes from, i.e., energy carriers. In this paper, UE was accounted for Mexico in . It was found that UE experienced a six-fold growth, led by the increasing share of mechanical drive and electric energy uses. Structural changes such as industrialization and complete electrification mainly drove UE transitions. Technological progress, mainly driven by the industrial sector, and electricity availability caused an improvement in the aggregate final-to-useful efficiency of the economy. In addition, the trend of increasing UE economic intensity shows that Mexico became more dependent on UE per unit of economic output during industrialization. The results suggest that UE trends were more influenced by structural transitions while final exergy trends were more influenced by economic fluctuations. It is concluded that energy policy design in developing countries undergoing or starting the process of industrialization should focus on: (1) improvements in final-to-useful efficiency, especially of the transportation sector and (2) growth of the productivity of UE. Keywords: energy transitions; useful exergy; energy decoupling IntroductionEnergy transitions describe the changes in energy quantity and quality and the way in which energy carriers ("either a substance or a phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes" [1]) are used in the economy [2,3]. These transitions, especially since the 18th century, are strongly related to wealth accumulation, population growth and improvements in the standard of living beyond Malthusian limits [4,5].A fundamental characteristic of energy transitions is that they are endogenous to the economic system, which means that they are both caused and effected by structural changes in the economy, see e.g., Grubler [6], , Feng et al. [8] and Rühl et al. [9]. Therefore, broader knowledge on these transitions may lead to adequate energy and environmental policies that boost sustainable development [10,11]. However, energy transition research has so far provided little understanding of economy-wide effects [12].One reason for this little understanding is that most research studies have been mainly focused on the primary and/or final level of energy use (see Figure 1) Another reason is the predominance of energy-based analysis in the literature compared to exergy-based analysis. Energy-based analysis takes into account the thermodynamic potential of an energy carrier, e.g., enthalpy. On the other hand, exergy-based analysis focuses on the maximum work that is theoretically obtainable from an energy carrier as it approaches equilibrium with its environment, i.e., exergy [20]. The latter analysis, as opposed to the former, is directly related to ...

“…Among these measures, improvement of energy efficiency plays an essential role [17][18][19]. By using a Logarithmic Mean Divisia Index (LMDI) approach, Guo et al demonstrated that improvement of energy efficiency was the major factor in alleviating the growth of CO 2 emissions in China's transport sector during the past decade [20].…”

Abstract:Energy efficiency is one of the key factors affecting energy consumption and greenhouse gas (GHG) emissions. By focusing on China's transport sector, this study comprehensively reviews and compares the energy efficiency performance of passenger vehicles, light-duty commercial vehicles, commercial road transport, commercial water transport, aviation transport and railway transport, and identifies the opportunities for further energy efficiency improvements. It is found that railway transport exhibited the greatest improvement in energy efficiency during the past decade, which was mainly driven by progress in its electrification. Passenger vehicles have also experienced considerable energy efficiency improvements, which can be mainly attributed to the establishment of mandatory fuel consumption standards. In contrast, commercial road transport has shown the least improvement, due to insufficient policy implementations. Based on the analysis, it is recommended that, as China's present policy framework to improve energy efficiency in the transport sector is generally effective, it should be consistently maintained and successively improved. Electrification represents a major opportunity for improvement of energy efficiency in the transport sector. Such potential should be fully tapped for all transport modes. Greater effort should be put into improving the energy efficiency of commercial road transport. The policy instruments utilized to improve the energy efficiency of heavy-duty vehicles should be as intensive and effective as the policy instruments for passenger vehicles.

“…The transportation sector accounted for around 7.7% of the total use of secondary energy flows (not including residential private transportation) [8]. Moreover, all transportation energy uses (including residential uses) increased by 66% between 1990 and 2012, driven by the increased demand for private vehicles and light truck transportation [14,15]. The energy demand by the industrial sector (including primary industries) increased 8% in the decade to 2012.…”

“…Also, it contributes to the scarce literature about the trends of economy-wide energy use and supply in Mexico. Guevara et al [6] summarized most of previous energy research about Mexico and pointed out that it had been mainly focused on sectoral analysis, addressing the residential, industrial, and transport sectors or specific industries; see [10][11][12][13][14][15][48][49][50][51][52][53].…”

The Status and Evolution of Energy Supply and Use in Mexico Prior to the 2014 Energy Reform: An Input-Output Approach †

et al. 2017

Abstract:In 2014, the Mexican government approved a bold energy reform that allows private energy companies to freely participate in the energy market (something prohibited during the previous eight decades). This reform is expected to significantly restructure the energy sector and boost and diversify the energy production. Moreover, changes in the energy sector and production might lead to structural changes in the rest of the economy and ultimately generate significant economic benefits for the country. Nevertheless, the fundamental role of the energy sector in this oil producing country makes the potential impacts of the reform complex to forecast. The objective of the study is to analyze the current state, evolution, and driving factors of the total primary energy use in Mexico in 2003-2012 (prior to the implementation of the reform) as a precedent for future analyses of impacts of the energy reform. The results show three driving factors of the evolution of primary energy use: final non-energy demand, direct energy intensity, and economic structure. Also, it was found that the energy sector has been in a precarious situation regarding its structure and efficiency. However, this situation had a small effect on the evolution of primary energy use.
