However, detailed studies of the marginal emissions impact from a heat pump have rarely been validated against historical data. This study estimates emissions using a backcast of actuals from 2018 in New England to infer the impact of heat pump conversions. The model suggests a heat pump would have emitted 68 % more CO2 than a 90 % efficient gas furnace. But if oil and coal plants had not been activated, the model suggests heat pumps would only have emitted 3.3 % more CO2 than a gas furnace. Carbon emissions vary with the relative efficiency of the marginal electric generator and heat pump. Heat pump efficiency declines during cold weather, coinciding with peak heating load. Emissions are dominated by short periods when coal and oil generation resources operate, coinciding with low temperatures. But even with coal and oil plants on the system, a hybrid heat pump - gas furnace configuration reduces CO2 emissions 5.6 % compared to a gas furnace alone. Thus hybrid operation is preferred where fossil fuels are primarily on the margin.<span><span><sup>1</sup></span></span></div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 3","pages":"Article 107477"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We validate our framework with case studies on investments in electric mobility in China, Brazil, India, Colombia, Türkiye and Chile. We argue that developing countries with wholesale power markets, and wholesale and retail power markets could attract investment in electric mobility, albeit with a proliferation of low total cost of ownership electric mobility investment options such as two and three-electric wheelers and investments such as electric buses perceived to have notable contributions to achieving environmental/climate objectives.

The heatmap showed that there were a few topics with high correlation values. For cluster analysis, “South”, “Country”, “Eskom”, “Power” and “Energy” had positive sentiments and contents. On the contrary, “Government”, “Africa” and “People” were topics of negative sentiments and contents. Only “ANC” connected neutral sentiments and content. “ANC”, “Africa” and “country” had an 81.77 % degree of centrality in the public digital discourse on access to electricity in SSA countries.

The research evaluates five dimensions of agricultural recovery: profitability, productivity, job creation effects, investment attraction, and household expenditures. The analysis, conducted using propensity score matching, indicates that solar-powered irrigation significantly enhances agricultural profitability, with solar users earning an average of $20.42 more per acre compared to diesel users (p = 0.001). Wheat productivity showed a modest increase from 0.151 to 0.179 tons per acre, though the difference was statistically insignificant (p = 0.365). Similarly, solar-based farms generated an average of 87.42 working days per year, compared to 75.30 days for diesel-based farms, but this difference was also not statistically significant (p = 0.60). Despite these mixed outcomes, the study highlights a significant shift towards the cultivation of summer crops, such as cotton, facilitated by more reliable water supply provided by solar-powered irrigation. These findings emphasize the importance of targeted interventions, including the promotion of advanced irrigation techniques and financial support for infrastructure development. Such measures are critical for maximizing the benefits of solar-based irrigation and ensuring broader, more sustainable agricultural recovery in the region.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 2","pages":"Article 107471"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet these challenges, the DoD will have to find ways to expand the portfolio of its energy sources, continue to refine its supply chains and delivery mechanisms for energy services, improve efficiency across systems, and maintain a focus on costs. This paper will focus on the electrification of aspects of operational energy within the joint force as a means of increasing the effectiveness and efficiency of energy at all levels of warfighting.

By employing the Structural Time Series Modelling method, the short- and long-run factors of income elasticities are found as 0.20 and 0.32, while the corresponding price parameters are determined as −0.08 for the short-term and −0.14 in the long-term, respectively. These elasticity estimations are crucial for informing policy-making processes, particularly in strategizing for the residential sector in Türkiye. The inelastic nature of these estimates, being less than 1, suggests that electricity constitutes a necessary commodity within the residential sector of Türkiye. It implies a limited sensitivity of consumers to fluctuations in price and income, indicating that changes in these factors do not significantly alter residential electricity demand in Türkiye. Additionally, this study extends its insights by providing forecasts for residential electricity demand. The projections indicate that by the year 2030, the electricity demand within Türkiye’s residential sector is projected to range between 90 and 106 Terawatt-hours (TWh).

Governments, utilities, planners, and the research community are working to advance a more nuanced understanding of energy equity, involving distributive, procedural, recognitional, and restorative aspects. Complete energy equity requires a holistic understanding of all these aspects, and energy planning should attempt to address them simultaneously. In practice, this can be challenging in contexts where the available pool of human and economic resources is limited. This article presents a case study of a community within the Navajo Nation to illustrate the challenges and implications in such contexts. The first challenge is the inevitable prioritization and compartmentalization of decision making due to the constraints imposed by the planners’ primary mandates, authority, place-based contextual factors, and available resources. The second – related – challenge is the impact of the resulting decisions on realized outcomes, and its effects on the community perceptions of – and confidence in – the planning institutions. The case study also finds that equity concerns of the utility’s end-customers may not always be uniform and are influenced by the customers’ perspectives, roles, responsibilities, and expectations. Thus, a more holistic view of energy planning is necessary to 1) capture the variations of equity opinions and priorities across all stakeholders, 2) to ensure that decisions and resource allocations by utilities, elected bodies, or governmental agencies occur on multiple fronts in a coordinated and transparent manner to advance energy equity targets.</div></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"38 1","pages":"Article 107456"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
