Energía y bienestar: una breve historia desde la perspectiva de los límites medioambientales

Energy: vital and fatal. Vital because a certain amount of energy has become indispensable for modern individuals and societies. Fatal because energy systems have produced the largest proportion of greenhouse gases since at least the second half of the twentieth century. Thus, it is essential to analyse energy issues from the point of view of its use, trying to answer questions such as: How much energy is required to maintain or improve levels of human well-being? Which countries have managed to achieve high levels of well-being with relatively low levels of energy use, and how? What impact does our understanding of human well-being have on how we think about the relationship between this and energy? This article presents the history of the study of the relationship between energy and well-being, imperative in the fight to mitigate climate change, from the perspective of environmental limits.Energía: vital y fatal. Vital pues cierta cantidad de energía se ha convertido en un aspecto indispensable para las sociedades y personas modernas. Fatal pues los sistemas energéticos han generado la mayor parte de las emisiones de gases efecto invernadero desde por lo menos la segunda mitad del siglo veinte. Por lo tanto, es indispensable analizar las cuestiones de energía desde el punto de vista de su uso buscando responder preguntas como ¿cuánta energía se requiere para mantener o mejorar niveles de bienestar humano?, ¿qué países han logrado alcanzar niveles altos de bienestar con niveles relativamente bajos de uso de la energía y cómo lo han logrado?, ¿qué impacto tiene nuestra comprensión del bienestar humano en cómo reflexionamos sobre la relación entre energía y bienestar? Este artículo tiene como objetivo presentar la historia del estudio de las relaciones energía-bienestar imperativa en la lucha por mitigar el cambio climático, desde una perspectiva de límites medioambientales

Following the ‘golden thread: Exploring the energy dependency of economies and human well-being

Climate change –one of the greatest threats to modern civilisation- has been largely driven by an exponential growth in world energy use in the last couple of centuries. However, societies and economies are dependent on energy use to maintain themselves and change. Thus, in this thesis I compare energy to a ‘golden thread’, which weaves through climate change, economic growth and human well-being. In this context, the challenge I set out to explore in this thesis was to find alternatives for decoupling societal and economic progress from environmentally harmful levels of energy use. In order to open the possibility space for decoupling the energy dependency of the economy from climate change, I used the holistic theoretical framework of surplus energy and developed a novel methodology for calculating Energy Return On Investment (EROI) at the national level. Similarly, in order to open the possibility space for decoupling the energy dependency of society (human well-being) from climate change, I developed an original theoretical framework, integrating the concepts of energy services and human needs, and tested it using an innovative methodology. I found that a national-level EROI can contribute to accelerate a transition away from fossil fuels, by providing evidence at a scale relevant for policymakers. Additionally, I found that the energy services and human needs framework, as well as the methodology to test it, provide a way to prioritise and explore alternatives of energy service delivery. I consider that both of these contributions point towards the possibility of having climate compatible energy dependent societies and economies, as long as there is a fundamental change in the framings, understanding, priorities and methodologies used to find and assess such possibility

Are citizen juries and assemblies on climate change driving democratic climate policymaking? An exploration of two case studies in the UK

In light of increasing pressure to deliver climate action targets and the growing role of citizens in raising the importance of the issue, deliberative democratic processes (e.g. citizen juries and citizen assemblies) on climate change are increasingly being used to provide a voice to citizens in climate change decision-making. Through a comparative case study of two processes that ran in the UK in 2019 (the Leeds Climate Change Citizens’ Jury and the Oxford Citizens’ Assembly on Climate Change), this paper investigates how far citizen assemblies and juries are increasing citizen engagement on climate change and creating more citizen-centred climate policymaking. Interviews were conducted with policymakers, councillors, professional facilitators and others involved in running these processes to assess motivations for conducting these, their structure and the impact and influence they had. The findings suggest the impact of these processes is not uniform: they have an indirect impact on policy making by creating momentum around climate action and supporting the introduction of pre-planned or pre-existing policies rather than a direct impact by truly being citizen-centred policy making processes or conducive to new climate policy. We conclude with reflections on how these processes give elected representatives a public mandate on climate change, that they help to identify more nuanced and in-depth public opinions in a fair and informed way, yet it can be challenging to embed citizen juries and assemblies in wider democratic processes

Illumination as a material service:a comparison between Ancient Rome and early 19th century London

Specific combinations of energy flows, material flows and stocks are responsible for those services that support social metabolism. However, few researchers go beyond energy services to ascertain the role that materials play in socioeconomic development. In this paper, we develop the concept and accounting method for material services, which we define as “those functions that materials contribute to personal or societal activity with the purpose of obtaining or facilitating desired end goals or states, regardless of whether or not a material flow or stock is supplied by the market”. In this respect, material services act as an intermediate step that incorporates stock to bridge the gap between resource consumption, accumulation and aspects of wellbeing. We provide a material service case study, which identifies the level of lighting experienced by urban Ancient Romans relative to that enjoyed by inhabitants of 1820s London (the Georgians). Our results show that the average Roman experienced 41,102 lumen-hour, which is more lighting than the Georgian value per capita (at 35,698 lumen-hour). In terms of fuel consumption, Georgians were four times more efficient than their Roman counterparts, but there was a trade-off between materials and energy, given that stock efficiency was 53 times lower than that of the Romans. This trend of improving fuel efficiency at the expense of materials appears to have continued into the 21st century, which holds important implications for sustainable development. Further research needs to be undertaken to ascertain whether this holds true for other material services such as heating, transport and shelter

Developing an input-output based method to estimate a national-level energy return on investment (EROI)

Concerns have been raised that declining energy return on energy investment (EROI) from fossil fuels, and low levels of EROI for alternative energy sources, could constrain the ability of national economies to continue to deliver economic growth and improvements in social wellbeing while undertaking a low-carbon transition. However, in order to test these concerns on a national scale, there is a conceptual and methodological gap in relation to calculating a national-level EROI and analysing its policy implications. We address this by developing a novel application of an Input-Output methodology to calculate a national-level indirect energy investment, one of the components needed for calculating a national-level EROI. This is a mixed physical and monetary approach using Multi-Regional Input-Output data and an energy extension. We discuss some conceptual and methodological issues relating to defining EROI for a national economy, and describe in detail the methodology and data requirements for the approach. We obtain initial results for the UK for the period 1997–2012, which show that the country’s EROI has been declining since the beginning of the 21st Century. We discuss the policy relevance of measuring national-level EROI and propose avenues for future research

What are the social outcomes of climate policies? A systematic map and review of the ex-post literature

It is critical to ensure climate and energy policies are just, equitable and beneficial for communities, both to sustain public support for decarbonisation and address multifaceted societal challenges. Our objective in this article is to examine the diverse social outcomes that have resulted from climate policies, in varying contexts worldwide, over the past few decades. We review 203 ex-post climate policy assessments that analyse social outcomes in the literature. We systematically and comprehensively map out this work, identifying articles on carbon, energy and transport taxes, feed-in-tariffs, subsidies, direct procurement policies, large renewable deployment projects, and other regulatory and market-based interventions. We code each article in terms of their studied social outcomes and effects, with a focus on electricity access, energy affordability, community cohesion, employment, distributional and equity issues, livelihoods and poverty, procedural justice, subjective well-being and drudgery. Our analysis finds that climate and energy policies often fall short of delivering positive social outcomes. Nonetheless, across country contexts and policy types there are manifold examples of climate policymaking that does deliver on both social and climate goals. This requires attending to distributive and procedural justice in policy design, and making use of appropriate mechanisms to ensure that policy costs and benefits are fairly shared. We emphasize the need to further advance ex-post policy assessments and learn about what policies work for a just transition

Energy consumption-based accounts : A comparison of results using different energy extension vectors

Increasing attention has been focussed on the use of consumption-based approaches to energy accounting via input-output (IO) methods. Of particular interest is the examination of energy supply chains, given the associated risks from supply-chain issues, including availability shocks, taxes on fossil fuels and fluctuating energy prices. Using a multiregional IO (MRIO) database to calculate energy consumption-based accounts (CBA) allows analysts to both determine the quantity and source of energy embodied in products along the supply chain. However, it is recognised in the literature that there is uncertainty as to the most appropriate type of energy data that should be employed in an IO framework. Questions arise as to whether an energy extension vector should show where the energy was extracted or where it was used (burnt). In order to address this gap, we undertake the first empirical MRIO analysis of an energy CBA using both vectors. Our results show that both the energy-extracted and energy-used vectors produce similar estimates of the overall energy CBA for the UK—notably 45% higher than territorial energy requirements. However, at a more granular level, the results show that the type of vector that should be employed ultimately depends on the research question that is considered. For example, the energy-extracted vector reveals that just 20% of the UK's energy CBA includes energy extracted within the UK, an issue that is upmost importance for energy security policy. At the other end, the energy-used vector allows for the attribution of actual energy use to industry sectors, thereby enabling a better understanding of sectoral efficiency gains. These findings are crucial for users and developers of MRIO databases who undertake energy CBA calculations. Since both vectors appear useful for different energy questions, the construction of robust and consistent energy-used and energy-extracted extension vectors as part of commonly-used MRIO model databases is encouraged
