To fill this gap, we adopt a Middle-Out Perspective (MOP) and use rich qualitative data including in-depth interviews to study the role of craft guilds within Germany's low-carbon transition, particularly in rooftop photovoltaic and heat pump installation. Our analysis demonstrates that guilds occupy pivotal ‘upper middle actor’ positions to resolve the ‘installation bottleneck’ from the middle-out. Situated between policymaking and on-the-ground installation, guilds have unique <i>agency</i> and <i>capacity</i> qualities deriving from preferential access to the local implementers of low-carbon transitions and legal commissions with critical tasks including training, informing, and associating installers. However, we find that guilds suffer from resource constraints, membership declines, and a lack of deliberate activation. Informal power structures and deficits of change makers exacerbate guilds’ <i>propensity</i> for inertia while unstable framework conditions and the dearth of strategic engagements leave guilds inactivated. Our extended MOP framework of <i>agency, capacity</i>, and <i>propensity</i> allows researchers and policymakers to attend to potentials and trade-offs between these qualities. By recognising the contextual social sphere of installation as potential, policymakers can design more effective implementation strategies that gain people’s support by ‘meeting them where they are’.</p>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10287-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More research into the gendered impacts of smart systems in Norway is needed.

This study explores the possibility of energy savings and reduction in energy costs associated with the installation of (Variable Speed Drives) VSDs on primary ventilation fans in below-ground coal mines. According to Ventilation-on-Demand (VOD), where air volume is changed according to demand at various time intervals, a nonlinear constraint optimization model is created to reduce energy costs and achieve better energy efficiency. To achieve accurate results at the fan's operating point, this model is also constructed to adhere to the affinity law of the fan. Tellegen's theorem and Kirchhoff's law are applied to model the ventilation system of the underground mine. The ventilation network was used to investigate energy and financial savings with various airflow scenarios. Load management is accomplished by figuring out the ideal start time for the mining schedule in accordance with the Time of Use (TOU) tariffs. A critical analysis of the Tandsi underground coal mine is presented to explain the impacts of the optimization model.

It is therefore essential to assess the environmental efficiency of airlines to urge them to adjust their actions promptly to meet the desired strategic objectives. This paper focuses on assessing the environmental efficiency of airlines using a network structure and constructs a three-stage airline network structure. Then, a non-convex meta-frontier DEA model with unified natural disposability and managerial disposability is proposed to assess the overall efficiency of 85 airlines for 2018–2019, based on data from 85 airlines worldwide for 2018–2019. The new model not only automatically determines whether an airline's inputs are natural or managerial disposable, but also measures the environmental efficiency of each region, while optimizing overall efficiency. Firstly, Ryanair has the highest overall efficiency among the 85 airlines in 2018–2019, and this increased efficiency is closely related to its excellent performance in handling carbon dioxide emissions. Secondly, the airline efficiency rankings obtained from the non-convex meta-frontier model and the convex meta-frontier model proposed in this paper are largely in line with each other.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 8","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of studying sustainability practices and their dynamics grows in light of recent global crises such as the COVID-19 pandemic and the energy crisis following the Ukraine war. These events both challenge and shape individual sustainable practices, offering opportunities for fostering individual sustainable practices and enhancing societal resilience. An online survey was conducted in Germany (n = 571, May 2023) to investigate sustainable behavior dynamics (mobility, energy-saving, and shopping habits) and to identify segments reflecting behavioral shifts. We found relative stability in sustainable mobility choices compared to pre-crisis times, with a tendency towards reduction, as well as an overall increase in energy-saving and sustainable shopping habits. Factor analyses revealed that sustainable mobility behavior (SMB) and sustainable consumer practices (SCP) formed two separate domains. Cluster analyses further identified four segments within each domain, each exhibiting unique behavioral patterns compared to pre-crisis practices. Examining individual variables, adopting more sustainable mobility practices was associated with sociodemographic factors (income, education, and area of living), higher levels of environmental awareness, institutional trust, and increased risk perceptions. Sociodemographic variables had less influence on sustainable consumer practices. Here, higher levels of knowledge, climate change awareness, trust, and risk perceptions played a significant role. Our findings highlight the importance of separately considering behavioral domains in understanding crises-induced changes in sustainability practices. Moreover, it is important to consider specific individual factors and to develop tailored interventions and policies to promote sustainable practices during volatile times.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 8","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10285-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper provides evidence on the interplay between digital real-time information and regulation of self-consumption for rooftop photovoltaics (PV) in Croatia. Croatian households that produce more annual electricity than they consume are automatically re-classified as renewable traders, which means additional administrative duties and less favorable tax treatment. This creates perverse incentives to reduce PV generation or increase energy consumption by year-end. We document the behavioural reactions to this policy design, indicating that energy production and consumption are highly elastic regarding regulatory incentives, but only if these incentives are made transparent and accessible with timely information. We collected two survey waves (<i>n</i> = 54 and <i>n</i> = 80) and smart meter data (<i>n</i> = 39), which illustrate the behavioural reaction before and after year-end. According to the survey wave before year-end, almost half of the participants considered curtailing their PV output. According to the smart meter data, a sizable share did indeed take action by shutting down PV production or by powering additional devices to reduce the surplus near year-end. In a second survey wave in the new year, prosumers provide ex-post insights on the specific measures taken to reduce surplus.
