The huge diffusion and rapid growth of the Data Centers industry not only increases the availability and quality of cloud and data services, but also the demand for electricity and water by the digital services industry. The decarbonization process requires the deployment of non-programmable renewable energy sources in power systems, requiring unprecedented attention to grid flexibility and securityIn this context, Data Centers can provide balancing services by Demand Response strategies, modifying or temporarily reducing their electrical consumptions during specific times. Thereby, this research first presents the energy consumption derived from an experimental survey carried out in an existent Data Center. On this basis, a numerical energy model developed using TRNSYS software has been calibrated and validated. Finally, the possibility for DC to participate in the electricity flexibility market a novel demand response strategy that exploits the fluctuations of indoor air temperature and humidity has been investigated. As a result, the proposed flexibility scenario gives rise to a reduction of the electricity needs of about 30% of the cooling load.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10357-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161739","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}

Modifying consumer behavior, particularly within the residential sector, which accounts for a substantial share of global energy consumption and carbon emissions, is crucial for reducing consumption and achieving sustainable development. Aiming to integrate the concepts of Responsible consumption (RC) and behavioral interventions within the Theory of Planned Behavior (TPB) theoretical framework, this research seeks to develop a conceptual model to explain and promote responsible energy consumption behavior. Research data were collected through questionnaires and expert interviews. Data analysis was conducted using the Fuzzy Delphi Method, Structural Equation Modeling (SEM) in SmartPLS4 software, and scenario writing employing the Cross-Impact Balance (CIB) method. In this study, Behavioral interventions (individual or combined) designed based on the principles of responsible innovation (RI) alongside TPB variables play a key role. The results indicated that combined interventions significantly impact the intention and behavior of Responsible consumption and, as mediating and moderating variables, play a significant role in translating intention into behavior. In contrast, individual interventions alone exhibit weaker effectiveness. Furthermore, 8 future-oriented scenarios for reducing household energy consumption were designed, revealing that participatory and supportive scenarios focused on promoting Responsible consumption behavior have a greater impact on behavior change. By integrating RI, TPB, and behavioral interventions within an analytical and scenario-based model, this research provides a novel framework for energy policymaking in developing countries. It emphasizes the operational and policy role of behavioral interventions.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161486","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}

Over the past decades, the average floor area per person has increased steadily, resulting in higher energy demand for building materials, heating and cooling. However, the distribution of floor area is not equal across different demographic groups and household compositions. Redistributing floor area offers a significant opportunity to save resources and reduce the need for new construction by avoiding unnecessary consumption. Strategies such as moving, sharing and rearranging can facilitate this redistribution in the residential sector. In order to assess the feasibility of these strategies, this paper examines the current residents’ behaviour in the residential sector regarding space use and explores the potential for change. It draws on empirical data from an online survey conducted in Germany, Sweden, Poland and Portugal. By conducting a cluster analysis of the collected data, the paper identifies two groups with the highest potential for change in residential space use. It examines their willingness to change their space use patterns and investigates the acceptance of specific strategies that could lead to a reduction in the need for new construction in the residential sector. In order to promote more efficient use of space in the residential sector, the paper recommends encouraging space sharing, supporting structural changes in dwellings, and providing incentives for moving from under-occupied dwellings. It advocates for the implementation of tailored policies that consider the characteristics of each group, along with targeted awareness-raising efforts to increase policy acceptance.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10343-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171344","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}

United Nations have declared ‘responsible consumption and production’ a sustainable development goal (SDG12). Energy sustainability and reduced GHG emissions can be achieved through responsible consumption, energy efficiency, adopting energy-saving technologies and policies. The proposed research investigated the energy-saving perspectives of Indian Generation Z (aged 15–24) and Millennials (aged 25–40). A comprehensive survey involving 556 Gen Z and Millennials explored their attitudes toward energy conservation, focusing on adopting energy-saving attributes, interest in emerging energy-saving technologies and policies, perspectives on global warming, willingness to sacrifice comfort, and the societal influences shaping their views. The findings revealed that 73% of Gen Z and 85% of Millennials prioritise ‘energy conservation. An in-depth understanding of these perspectives holds significant potential for crafting effective, future-ready energy strategies and policies for sustainable development. Acceptance rate of all energy-saving technologies, except device remote control, among the Gen Z and Millennials is above 75%, which is a positive sign towards sustainability. Gen Z and Millennials share similar opinions on the perspectives towards sacrificing comfort for energy saving, influence of society on energy conservation and energy-efficient technologies. They differ in perceiving energy-saving opportunities and energy-saving policies. The findings are validated using statistical tools and ANOVA.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170588","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 energy-saving behavior of employees is intricately shaped by a confluence of psychological and organizational factors, personal norms, environmental awareness, and environmental consciousness. However, the combined impacts of organizational commitment and organizational citizenship behavior in influencing employees' energy-saving intentions and behaviors have received little attention, despite prior studies acknowledging the importance of both individual and organizational factors. This study consists of two separate research studies. Study I included a survey of 354 service employees in Adana, Türkiye, employing a convenience sampling method to quantitatively assess the impact of individual attitudes, social cognitive factors, and job attitudes, specifically organizational commitment and organizational citizenship behavior, on employees' energy-saving behaviors. The Theory of Planned Behavior and Social Exchange Theory were incorporated to create a comprehensive explanatory model. The results of structural equation modelling underscored the substantial influence of organizational citizenship behavior on energy-saving behavior. Expanding on these findings, Study II utilized an observational methodology, engaging 25 employees from the same sample, who were monitored by five trained observers to gain further insights into the actual manifestations of energy-saving behaviors in workplaces. The observational study has also confirmed the effect of organizational citizenship behavior on energy-saving behavior. In total, these complementary studies provide a comprehensive understanding of the factors affecting employees’ intentions and behaviors regarding saving energy and offer practical insights for formulating effective organizational policies and interventions to encourage sustainable energy practices among employees.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169258","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}

In Finland, these enterprises are vital for the national economy and sustainability goals but face significant barriers to energy optimization and Industry 4.0 adoption. Existing research often treats manufacturing SMEs as a homogeneous group, not addressing the diversity of barriers and drivers across micro, small, and medium-sized organizations across this sector. This paper, based on the <i>Enertelligence</i> -project conducted in Finland’s Ostrobothnia region—one of the country’s most industrialized areas—studies these differences through interviews with manufacturing SME managers, utilizing a maturity table to reveal variations in readiness and maturity across company sizes. The findings show that SMEs’ size significantly influences energy transition readiness, influenced by available resources, technological capabilities, and willingness to act. Additionally, external factors such as regulatory complexity and limited market incentives further hinder progress. The research introduces the innovation ecosystem approach as a regionally grounded theoretical framework to support manufacturing SMEs in overcoming these challenges. The insights have wider relevance for Finnish industrial policy and provide practical guidance for policymakers, stakeholders, and researchers seeking to accelerate sustainable modernization within the manufacturing SME sector.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169307","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}

However, their precise impacts are still insufficiently researched. To address this gap, this paper examines their effects on energy consumption in European Union countries from 1995 to 2022 while controlling for economic development, environmental degradation, industrialization, urbanization, and trade openness. The results, obtained using fixed effects feasible generalized least squares and two-stage least squares estimators, reveal that energy import dependence and economic policy uncertainty significantly and negatively affect final energy consumption across different model specifications and robustness analyses. This contrasts with the impact of geopolitical risk, which was positive but of lesser magnitude and only significant when tested jointly or controlling endogeneity. Additionally, the paper highlights two particularly intriguing and novel findings from the results, providing valuable implications for energy and environmental policy. First, the unexpected positive relationship between carbon dioxide emissions and energy consumption suggests that extreme weather events driven by climate change are already disrupting energy systems in Europe, resulting in higher energy consumption. Second, while geopolitical risk increases energy consumption, energy security risk and economic policy uncertainty have the opposite effect, likely due to heightened uncertainty, which discourages investment and slows technological progress.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 6","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166532","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}
