The findings of estimation revealed a positive and statistically significant effect of financial development and income on CO2 emissions in Kazakhstan. Numerically, a 1% increase in financial development is associated with a 0.17% rise in CO2 emissions. The positive impact of financial development on CO2 emissions can be seen as an advanced financial system can boost funding accessibility for energy and carbon-intensive sectors, such as manufacturing and large-scale infrastructure projects, potentially resulting in increased output and economic growth, often accompanied by elevated emission levels. In addition, exports have a negative influence on CO2, whereas the impacts of renewable energy consumption are insignificant. Our findings suggest that Kazakhstan’s policymakers should prioritize channeling financial resources towards eco-friendly technologies, facilitating energy transitions, and promoting sustainable economic activities.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140008983","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 paper studies a representative sample of 1,468 Danish households to investigate SHT diffusion, social differences in SHT adoption, and correlations between SHT and energy consumption, divided into appliance use and heating. The results indicate that entertainment and home security are the most popular SHT services in Denmark and that SHT is more widespread among younger households, especially for entertainment and robotic help. In contrast, smart heating systems are more widespread among older households. Living in a detached house seems to increase the likelihood of having SHT, while the highest income group appears more likely to have security systems, and technical education seems associated with the adoption of SHT for heating management. Finally, smart security systems were associated with higher electricity consumption, and SHT for electricity management was associated with higher heating consumption and to a lesser extent higher electricity consumption, but there was no significant correlation between having smart heating control and heating consumption.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10202-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140009205","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}

To tackle this challenge, interventions such as feedback and social comparison are increasingly applied in combination with persuasive technologies. We report the results from a field experiment conducted in a Swiss energy-efficient district where two consecutive behavioural interventions involving persuasive technologies were tested: (1) real-time hot water consumption feedback while showering and (2) a weekly newsletter with social comparison feedback regarding overall hot water consumption, including hot water saving tips, in addition to real-time feedback. Based on the data from 33 households, we found that, compared with the baseline consumption, hot water consumption was 12.4% lower immediately after the real-time feedback intervention and 16.1% lower after the combined intervention. Hot water consumption increased again after the intervention phase, but it was still 9.7% lower than the baseline consumption 2 months after the combined intervention and 8.6% lower 4.5 months after the combined intervention.

The above solution is developed for a real frozen food factory operating in Lazio region (Italy) introducing a sewage sludge dryer and a gasifier to produce syngas. The software Aspen Plus is adopted to numerically simulate the gasification process, using a literature validated model, while the dryer and the already present combined heat and power (CHP) plant are dynamically modelled in TRNSYS environment.

This paper theoretically estimates the 2022 burden of energy bills on Spanish households, with a particular focus on vulnerable ones. This assessment is carried out by simulating alternative scenarios to evaluate the consequences of the energy prices rise and the effect of the national emergency measures implemented to counteract the energy crisis impact. A disproportionate expenditure indicator is also applied to the vulnerable consumer group that benefitted from the social tariffs to provide a first proxy of the 2022 energy poverty situation in Spain. The results show that these policies significantly reduced regulated market consumers’ bills, the vulnerable ones being the most protected by them. However, the high energy burden estimated for the latter category of customers reflects the insufficient ‘energy efficiency preparation’ of these households to react to energy price shocks.

In order to achieve the targeted climate goals for the building sector, it is necessary to make the best possible use of refurbishment opportunities for energy retrofits. Furthermore, it must be considered that the younger the building, the lower the potential for energy savings. The most challenging, yet required, energy retrofits are all yet to come. Given the importance of the refurbishment cycle, the question arises as to what the theoretical refurbishment rate is, what the actual energy retrofit rate is, and what it needs to be in order to meet the climate targets for the residential building stock. The aim of this paper is to model the evolution of the size and retrofit status of national building stocks. This is to be done against the background of the deviation from the actual and theoretical refurbishment cycle. Using current statistics and the past development of the German residential building stock, central parameters like living space, new construction, deconstruction, and the retrofit rate are modeled endogenously. For the latter, influences of economic conditions are implemented through an exogenously set black box variable. The retrofit rate represents a deep energy retrofit and thus allows an easy connection of the model with energy parameters for building classes defined in the web database TABULA for 20 European countries. The results are of relevance for modeling the energy efficiency status of the building stock and deriving suitable conditions for increasing retrofit rates also in other countries. The results show that increasing the energy retrofit rates to 2%/a or more is largely unrealistic. Instead, the focus should be on weak points, especially where short-term savings are concerned. This applies in particular to facades, basement ceilings, and heating systems as well as the efficient use of energy in buildings.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"17 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-024-10189-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139754099","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}
