The study uses the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB) to investigate consumers' intentions to use energy-efficient appliances. Data were collected via online survey from 300 Indian consumers. The results show that positive consumers intention to purchase energy-efficient appliances are perceived ease of use, attitude, subjective norms, and perceived behavioral control. However, no significant relationship was found between perceived usefulness and consumer intention to adopt such appliances. The study ends with actionable recommendations for marketers, policymakers, and sustainability advocates to create pertinent educational and communication initiatives.

This short communication summarises the results of a structured analysis of the support measures to reduce the negative impacts of the energy crisis on households implemented in Austria along two criteria derived from the literature: social effectiveness, i.e. the degree to which they are targeted to vulnerable households, and energy efficiency incentives. The support measures implemented in Austria have generally lacked (social) targeting. Broad compensation measures tend to impede price signals that incentivise energy savings and entail higher fiscal costs. In the medium and long run, these measures, like tax reductions, price caps or untargeted lump-sum payments, should therefore be replaced by measures focussing on income support for the most vulnerable households. This would enable a more effective use of resources, improve social effectiveness, and contribute to increasing energy efficiency.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10296-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995083","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}

It is found that supportive policies may stimulate the willingness of residents to install residential PV. These policies are followed by negative incentives, positive incentives, and guiding policies, among which the most critical variable is perceived usefulness (PU). In Urumqi and other places where roof photovoltaic is not popular, the above conclusions can be applied to the promotion policy of roof photovoltaic.

However, the effect of such pricing schemes varies substantially across contexts and depends on the expectations that dynamic price signals integrate into everyday routines and rhythms. This paper investigates the flexibility of the everyday routines and rhythms of households. Based on visits to 11 Danish households and interviews with electricity customers new to RTP, the study provides three insights. First, households expressed confusion over terminology for dynamic pricing products and low interest in flexible energy demand. Second, everyday practices (already) appeared flexible but for reasons other than energy demand flexibility. Third, energy habits were important for providing meaning to everyday practices. The study shows that energy flexibility is not just about energy demand, but rather about all the other activities that form routines and rhythms in everyday life. We suggest (1) designing products that reflect ‘natural’ or ‘societal’ daily rhythms, (2) focusing on the engaged households, and (3) being aware that for some households, changes in pricing, including new payment schemes, might put extra pressure on already harried everyday routines.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938763","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}

This study uses fuel poverty indicators to determine household vulnerability to increase in energy price in Japan. A web questionnaire was conducted asking about household income and fuel bills in 2021 and 2022, using Kobe City, Japan, as a case study. As the result, the percentage of fuel-poor households in 2022 was 5.39%, an increase of 0.23% over 2021. This suggests that fuel-poor households are increasing in response to increasing energy prices. The 2022 fuel poverty rate for elderly households was 1.48%, and it was 3.91% for households other than the elderly. Analysis result regarding the characteristics of households determined to be fuel-poor indicated that single-parent households were more likely to fall into fuel poverty than average households. A model combining binomial logistic regression and multiple regression analyses was derived to measure the effect of fuel poverty measures based on the questionnaire survey results. The study results of measures to reduce the time spent using climatization equipment during the daytime in summer by implementing energy sharing showed that all households and single-parent households could move out of fuel poverty. However, elderly households could not move out of fuel poverty, and an additional condition for breaking out of fuel poverty was an increase in the annual household income of elderly households by 0.2 million JPY (Japanese Yen).</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10292-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939014","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}

Despite substantial energy conservation observed across sectors, research has inadequately explored the reasons behind these savings. This study bridges this gap by analyzing the discourse on energy conservation during the crisis in Germany, using Twitter data. We analyse a set of 136,837 tweets from January 2022 until May 2023. The analysis consists of two approaches based on natural language processing (NLP): First, we conduct word counts within the days with high tweet activity related to energy saving to identify specific triggers. For a broader quantitative analysis, we then use text classification to categorize the data set into different aspects as well as different stances and investigate how these evolve during the crisis. Our results show a heightened focus on energy conservation in the Twitter debate during the crisis, reflected in an increase of the average monthly tweets from 730 (before 2022) to 8,552 in 2022/2023. Regarding the motivations, ethical concerns linked to the war play a larger role in the initial months, while other factors such as energy costs, solidarity aspects, and climate change are consistently present throughout the debate. Additionally, we note significant negative discourse regarding the policy measures enacted during the crisis, indicating that policy backlash is a critical issue, at least in the realm of the Twitter debate. Given the vital role of energy efficiency in combating climate change, comprehending the motivations and de-motivations behind voluntary energy conservation during the crisis offers valuable insights. This understanding can inform future policies aiming to encourage energy savings.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912958","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}

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.
