Fueling Culture
How has our relation to energy changed over time? What differences do particular energy sources make to human values, politics, and imagination? How have transitions from one energy source to another-from wood to coal, or from oil to solar to whatever comes next-transformed culture and society? What are the implications of uneven access to energy in the past, present, and future? Which concepts and theories clarify our relation to energy, and which just get in the way? Fueling Culture offers a compendium of keywords written by scholars and practitioners from around the world and across the humanities and social sciences. These keywords offer new ways of thinking about energy as both the source and the limit of how we inhabit culture, with the aim of opening up new ways of understanding the seemingly irresolvable contradictions of dependence upon unsustainable energy forms. Fueling Culture brings together writing that is risk-taking and interdisciplinary, drawing on insights from literary and cultural studies, environmental history and ecocriticism, political economy and political ecology, postcolonial and globalization studies, and materialisms old and new.

Let's Talk About Dead Pool: How We Discuss the Shallows of Reservoirs
The term “dead pool” has been circulating in water resources discourse in multiple ways, prompting confusion about what it means. In this commentary, we aim to clarify the definition of dead pool (and related terms describing critical reservoir elevations) to encourage clearer conversations about reservoir storage decline going forward. We also make two arguments to animate future research about the shallows of reservoirs. First, we suggest that critical reservoir thresholds such as dead pool are better thought of as dynamic and multifaceted rather than as static and singular elevations. Second, we offer a typology that aims to distinguish among three different types of reservoir storage decline. Taken together, a shared vocabulary about reservoir levels and a more nuanced conceptualization of how reservoirs shrink can better situate water scholars and policymakers to understand and manage reservoirs in an era of water overuse and climate change.
review of life cycle assessments on wind energy systems
PURPOSE: Several life cycle assessments (LCAs) of wind energy published in recent years are reviewed to identify methodological differences and underlying assumptions. METHODS: A full comparative analysis of 12 studies were undertaken (ten peer-reviewed papers, one conference paper, and one industry report) regarding six fundamental factors (methods used, energy use accounting, quantification of energy production, energy performance and primary energy, natural resources, and recycling). Each factor is discussed in detail to highlight strengths and shortcomings of various approaches. RESULTS: Several potential issues are found concerning the way LCA methods are used for assessing energy performance and environmental impact of wind energy, as well as dealing with natural resource use and depletion. The potential to evaluate natural resource use and depletion impacts from wind energy appears to be poorly exploited or elaborated on in the reviewed studies. Estimations of energy performance and environmental impacts are critically analyzed and found to differ significantly. CONCLUSIONS AND RECOMMENDATIONS: A continued discussion and development of LCA methodology for wind energy and other energy resources are encouraged. Efforts should be made to standardize methods and calculations. Inconsistent use of terminology and concepts among the analyzed studies are found and should be remedied. Different methods are generally used and the results are presented in diverse ways, making it difficult to compare studies with each other, but also with other renewable energy sources.
FMEA Risk Assessment Method for Aircraft Power Supply System Based on Probabilistic Language-TOPSIS
The failure mode and effect analysis (FMEA) method, which estimates the risk levels of systems or components solely based on the multiplication of simple risk rating indices, faces several limitations. These include the risk of inaccurate risk level judgment and the potential for misjudgments due to human factors, both of which pose significant threats to the safe operation of aircraft. Therefore, a Probabilistic Language based on a cumulative prospect theory (Probabilistic Language, PL) risk assessment strategy was proposed, combining the technique for order preference with similarity to an ideal solution (TOPSIS). The probabilistic language term value and probability value were fused in the method through the cumulative prospect theory, and a new PL measure function was introduced. The comprehensive weights of evaluation strategies were determined by calculating the relevant weights of various indicators through the subjective expert weight and objective entropy weight synthesis. So, a weighted decision matrix was constructed to determine the ranking order close to the ideal scheme. Finally, the risk level of each failure mode was ranked according to its close degree to the ideal situation. Through case validation, the consistency of risk ranking was improved by 23.95% compared to the traditional FMEA method. The rationality of weight allocation was increased by 18.2%. Robustness was also enhanced to some extent. Compared with the traditional FMEA method, the proposed method has better rationality, application, and effectiveness. It can provide technical support for formulating a new generation of airworthiness documents for the risk level assessment of civil aircraft and its subsystem components.
Evolving Concept of Energy Communities in the European Union
In accordance with the goal approved by the Council of the European Union, a European climate-neutrality must be achieved by 2050. Namely, the European Union must significantly reduce greenhouse gas emissions and find ways to compensate for the remaining and unavoidable ones. Within the framework of the European Green Deal, which is a set of policy initiatives to achieve climate neutrality goals, energy communities are considered in the context of two initiatives: a just transition and clean and safe energy at an affordable price. Within the latter, energy community is seen as citizen-led actions in the energy sector that will help pave the way for the transition to clean energy.
Impacts of wildland fire effects on resources and assets through expert elicitation to support fire response decisions
A modelling framework to spatially score the impacts from wildland fire effects on specific resources and assets was developed for and applied to the province of Ontario, Canada. This impact model represents the potential ‘loss’, which can be used in the different decision-making methods common in fire response operations (e.g. risk assessment, decision analysis and expertise-based). Resources and assets considered include point features such as buildings, linear features such as transmission lines, and areal features such as forest management areas. Three categories of fire impacts were included: social, economic and emergency response. Category-specific scores were determined through expert elicitation and then adjusted to account for fire intensity. Expert elicitation was shown to compare favourably with other methods in terms of the complexity, time, set-up cost and operational use. When compared with historical fire data from Ontario, it was found that impact model scores were associated with the objective to suppress or monitor fires. The model framework provides a consistent pre-fire impact assessment to support individual fire response decisions. The impact assessment can also represent the total impact for areas of Ontario that do not have prescriptive response in a formal fire response plan.
Social Innovation and Nonprofit Resource Provision: A Discourse Analysis
This research adopts a resource dependency approach to support the process of social innovation application within the context of nonprofit resource procurement using a comparative sample of re- source-providing organizations (n = 8) and nonprofit resource recipients (n = 10). An organizational discourse analysis was adopted to explore concepts of power and legitimacy across groups revealing several ways that social innovation is employed and challenged by both resource recipients and providers. Further, a text coverage analysis revealed several discrepancies with the use of terminology between sub-samples. Together, these novel analytical approaches provide a narrative regarding the ways in which social innovation is co-conceptualized within nonprofit resource provision, including examining the role of language and power between stakeholder groups. Cette recherche adopte une approche de axée sur la dépendance aux envers les ressources pour soutenir examiner le processus d’application de l’innovation sociale dans le contexte de l’approvisionnement en ressources à but non lucratif. Pour réaliser cet objectif, la recherche en utilisantre-court à un échantillon comparatif d’organisations fournissant des ressources d’une part (n = 8) et\\ de bénéficiaires de ressources à but non lucratif de l’autre (n = 10). Une Par surcroît, une analyse du discours organisationnel a été adoptée pour explorer les concepts de pouvoir et de légitimité au sein de ces groupes, révélantdémontrant plusieurs façons dont l’innovation sociale est utilisée et contestée à la foisautant par les fournisseurs de ressources que par les bénéficiaires et les fournisseurs de ressources. De plus, une analyse de la couverture textuelle a révélé plusieurs divergences dans l’utilisation de la terminologie entre les sous-échantillons. Ensemble, ces diverses nouvelles approches analytiques fournissent permettent, par l’examen du rôle du langage et du pouvoir entre groupes de parties prenantes, d’élaborer une récit narration sur la manière dont l’innovation sociale est co-conceptualisée dans la fourniture de ressources à but non lucratif, notamment en examinant le rôle du langage et du pouvoir entre les groupes de parties prenantes.
Shared Understanding of Local Energy Community Terminology: A Catalyst for Interdisciplinary Collaboration and Stakeholder Engagement
Local Energy Communities (LECs) are an essential component of the clean energy transition in Europe. However, differences in terminology and interpretation across disciplines and among stakeholder groups present challenges to their effective development and operation. This paper explores three key concepts frequently encountered in LEC research and practice: prosumers and self-consumption, flexibility and demand response, and uncertainty. We provide both a Power Systems and an Operations Research (OR) perspective on each term, highlighting how varying definitions can lead to misunderstandings and misaligned decision models. By promoting greater clarity and shared understanding of these terms, we aim to support more effective interdisciplinary collaboration and the development of robust decision support tools for the design and operation of LECs.
