Abstract The net energy implications of the transition have so far been analysed at best final stage. Here we argue that expanding analysis to useful stage is crucial. We estimate fossil fuelsʼ useful-stage returns on investment (EROIs) over period 1971–2020, globally and nationally, disaggregate EROIs by end use. find (~3.5:1) are considerably lower than (~8.5:1), due low final-to-useful efficiencies. Further, final-stage EROI for which electricity-yielding renewable would deliver same as...
150 years ago, Stanley Jevons introduced the concept of energy rebound: that anticipated efficiency savings may be “taken back” by behavioural responses. This is an important issue today because, if rebound significant, this would hamper effectiveness policies aimed at reducing use and associated carbon emissions. However, empirical studies which estimate national are rare and, perhaps as a result, largely ignored in energy-economy models policy. A significant difficulty lies components...
The UK has been one of the few countries that successfully decoupled final energy consumption from economic growth over past 15 years. This study investigates drivers in productive sectors between 1997 and 2013 using a decomposition analysis incorporates two novel features. Firstly, it to what extent changes thermodynamic efficiency have contributed overall sectoral intensities. Secondly, analyses how much structural change economy is driven by offshoring energy-intensive production...
To meet climate change mitigation objectives, international institutions have adopted targets aimed at reducing or ending growth of primary energy consumption. Simultaneously, continued economic is forecasted to human development goals. Together, declining consumption and rising gross domestic product (GDP) called "absolute decoupling." However, absolute decoupling unprecedented for the world economy as a whole (since least 1971). Is "Mission impossible?" Given high stakes, we need clearer...
In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on efficiency. We develop a long-run, worldwide societal exergy analysis focused electricity. Our 1900–2017 world database contains carriers used in production, final end-uses, and efficiencies. find primary-to-final (i.e. conversion) efficiency increased rapidly from 1900 (6%) 1980 (39%), slowing 43% 2017 as...
The history of rail transport can offer valuable insights for future energy transitions due to its importance in promoting clean mobility. There is a complex interplay between the evolution railway network, fuel consumption, efficiency, service, and CO2 emissions that requires further exploration. We developed dataset covers use all stages transportation, as well length track, at world scale. To deal with missing data we utilized machine learning techniques first time historical...
Abstract Societal exergy analysis examines the flows of energy and through societies, from primary (e.g. oil) to final gasoline) useful propulsion) stages. By extending study stage, new insights into under-represented role in economic growth have been made. However, currently (a) country coverage is patchy incomplete, (b) available data are based on varying methods assumptions including efficiencies rather than engineering data, (c) datasets constructed using piecemeal computational...
In response to the oil crises of 1970s, energy accounting experienced a revolution and became much broader field analysis, in part by expanding along conversion chain from primary final useful services, which satisfy human needs. After evolution specialization, analysis today addresses topics entire chain, including systems, resources, carbon emissions, role services promoting well-being development. And expanded would benefit common framework that provides data structure uniformity...
<title>Abstract</title> Achieving a good life for all within planetary boundaries is essential sustainability. But analysing this goal hindered by problems of definition, measurement, and the large number potentially relevant factors. The indicator ‘years life’ (YoGL) defined as years person can expect to live above absolute poverty, enjoy physical cognitive health, experience positive satisfaction 1. YoGL has been quantified 2, but how it depends on resource requirements other potential...
Development of energy policy is often informed by economic considerations via aggregate production functions (APFs). We identify a theory-to-policy process involving APFs comprised six steps: (1) selecting theoretical energy-economy framework; (2) formulating modeling approaches; (3) econometrically fitting an APF to historical and data; (4) comparing evaluating (5) interpreting the economy; (6) policy. find that choices made in Steps 1–4 can lead very different interpretations economy (Step...
Capital–labour–energy Constant Elasticity of Substitution (CES) production functions and their estimated parameters now form a key part energy–economy models which inform energy emissions policy. However, the collation guidance as to specification estimation choices involved with such energy-extended CES is disparate. This risks poorly specified functions, knock-on implications for downstream energy–economic climate In response, first step, this paper assembles in one place major...
Physical Supply Use Tables overcome some of the main limitations commonly used Energy Extended Input Output Analysis by describing Conversion Chain in energy terms only. In this paper, we build on recent advances field to construct a Multi-Regional Table framework. We use data from International Agency and have developed open source R packages, thereby enabling easy adoption present work. The new framework enables analysts take into consideration trade products track flows across regions....
Energy flowing through societal energy conversion chains (ECCs) enables economic activity and facilitates human flourishing.To understand growth well-being, the field of analysis (Common, 1976) evaluates ECCs from primary stage (resources extracted environment, such as coal, oil, natural gas, wind, solar), to final (energy purchased by consumers, refined petroleum electricity), useful desired end user, heat, motion, light), sometimes services (such thermal comfort, transport,...
Extracting, processing, and delivering energy requires itself, which reduces the net available to society yields considerable socioeconomic implications.
Given the climate change emergency, reducing energy consumption, which is responsible for most greenhouse gases emissions worldwide, a priority. However, strong historical link between consumption and economic growth questions whether continued compatible with conservation targets. Conventional final analysis (common methods applied at stage) has provided limited insights to this nexus. In response, paper explores extent useful stage provides additional using three common methods: aggregate...
