This paper identifies a normalisation of following electricity prices online during the crisis and changing practices accordingly, the aim of the paper being to learn from this normalisation theoretically as well as policy-wise. The paper is based on a quantitative survey (N = 1000) and in-depth qualitative interviews (n = 30). Results showed that among those who indicate that they have flexible electricity prices almost 70% say that they follow prices daily, and an even larger share indicate that they are more aware of the timing of their electricity use compared to one year ago. Furthermore, more than half of the households used timers on their washing machines and dishwashers to time-shift appliance-use. Through an analysis of variation in interest and practices of time-shifting, we construct a parameter that we call ‘care for the energy system’, which showed more correlations than households’ socio-economy. The qualitative interviews revealed how experiences and engagement in time-shifting of practices for some households was prompted by tight economic constraints and for other households by care for energy and interest in green energy consumption. The results suggest that variable prices coupled with media and authority communication can encourage people to care for the energy system through time-shifting. However, as economic incentives can have social consequences, price signals should be coupled with financial support for vulnerable households.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10327-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879740","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}

Energy poverty can be measured through three indicators: (i) arrears on utility bills (Arrears), (ii) ability to pay to keep the home adequately warm (Inadequately Warm), and (iii) the presence of a leaking roof, damp walls or rotten windows (Leaks). The novelty lies in quantifying energy poverty with these indicators and analyzing convergence in various regions, including the application of a robustness ordered-logit text and a slope-homogeneity test. The empirical results show that countries with the lowest Arrears scores, like Norway and Sweden, exhibit weak convergence, while those with the highest, such as Greece and Türkiye, demonstrate absolute convergence.

The total final energy consumption of the country stands at 47% for the residential sector, with an average of 31% and 7% for refrigerating and air conditioning, respectively. Improving energy efficiency in the residential sector will not only improve both local and global energy use but will also improve carbon emission reduction. Hence, to ensure that this energy efficiency is achieved, the country enacted four legislative instruments to regulate the importation of cooling appliances (refrigerating and air conditioning), lighting, and other household appliances. These legislative instruments are to ensure that these appliances meet the requirements of the minimum energy performance standards (MEPS). This study provides a quantitative performance evaluation of energy, energy savings, and carbon emissions through the adaptation of the minimum energy performance standards (MEPS), cooling appliance standardization, and labeling programs for Ghanaian households using the appliance and equipment climate impact calculator (MEPSY) modeling method. This quantitative evaluation (energy efficiency policy documents) is based on data acquired from governmental agencies responsible for the energy sector. The outcome revealed that the MEPS program in Ghana has yielded a total savings of over USD 3,100 in financial savings on electricity bills due to energy savings of 23,100KWh in the household sector from 2010 to 2020, while a total of over 12,650GWh of electricity savings was made, translating into financial savings of over USD 2 billion in electricity bill savings with a carbon reduction of 6.5 million tons within the same period at the national level.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856614","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 proposes a methodology to evaluate the effectiveness of Sustainable Energy Action Plans (SEAPs) and Sustainable Energy and Climate Action Plans (SECAPs) in terms of reducing carbon dioxide emissions in the regions of Apulia and Sicily. The CO<sub>2</sub> emissions are analyzed at the provincial level, before and after the approval of the plans by the municipal council, using homogeneous consumption data from national sources, rather than from data declared by the CoM signatories themselves. The methodology adopted combines the analysis of variance and compound annual growth rate (CAGR) of emissions, both total and per capita, with an assessment of the level of involvement of municipalities and the population in CoM plans. Through Pearson's coefficient, the correlation between the spread of plans and emissions at the provincial level was also assessed. The main results show that Apulia and Sicily, with a share of approved plans of 45.5% and 87.7%, respectively, experienced a reduction in total emissions of 12.1% and 21.2%, and per capita of 9.3% and 18.7%, in the period after municipalities submitted their SEAPs or SECAPs. A greater effectiveness of the plans is denoted in Sicilian provinces than in Apulian ones. These findings underscore the importance of emissions monitoring by signatory local governments, particularly through a uniform methodology, as well as monitoring at the provincial and regional levels, implemented by the Covenant Territorial Coordinators (CTCs), to assess the implementation of the action plans and ensure that regional and national emission reduction targets are met.</p></div>","PeriodicalId":537,"journal":{"name":"Energy Efficiency","volume":"18 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12053-025-10325-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840463","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}

The GAHP unit was installed at the Toronto and Region Conservation Authority's Archetype Sustainable Houses (ASH), and its heating and cooling capacities, Gas Utilization Efficiency (GUE), Coefficient of Performance (COP), and economic-environmental performances were analyzed. The GAHP's performance during the cooling season aligned with expectations. However, in the heating season, its effectiveness significantly declined at outdoor air temperatures below - 1.5 °C, rendering it less efficient than other natural gas-based technologies. This significant decrease in heating efficiency during extreme cold raises concerns about its practicality for use in Canadian houses. An Excel-based screen tool was created with a validated performance curve to assess the feasibility of the GAHP in five major Canadian cities (Toronto, Montreal, Halifax, Edmonton, and Vancouver). Vancouver achieved the highest GUE at 108%, while Edmonton had the lowest at 90%. Only Vancouver exceeded a GUE of 100% using a 50% Propylene Glycol (PG)/water mixture. During the cooling season, the GUE was about 58% for all chosen cities.

The baseline results for the period 2000–2021 based on dynamic panel data models indicate that more final energy consumption in households per capita reduced Gini index, but increased gender pay gap.

Given such limitations, consumption from heightened equipment use (“rebound”) and, on occasion, higher than previous consumption (“back fire”) therefore reduce or negate the welfare effects from residential EE incentive programs. EE labels and other means to provide information have been used to overcome consumer ‘inattention’, and to attempt to convert EE procurement into ‘credence purchases’ – where equipment is purchased on faith in the label. The limits to such information campaigns (“nudge initiatives”) have been exposed in recent years. On the supply side, raising tariffs across the board might be politically unsustainable, and might not always lead to lower energy consumption, given the relative inelasticity of demand, especially in the context of residential end-use.
