It examines the impact of policy instruments like subsidies on affordability and market competitiveness while evaluating E2Ws' practicality in supporting Vietnam's clean energy transition. This study indicates that while E-Motorcycle has the highest TCO, followed by ICE-A motorcycles, E-Bikes have the lowest TCO. The E-motorcycle's high TCO indicates that premium electric models still face financial challenges in terms of overall affordability. Reduction in sticker price emerges as the most effective incentive, offering the largest decrease in TCO. Lower cost electric two-wheelers, such as E-Bikes, which have lower performance, are currently less expensive than two-wheelers running on internal combustion engines. Mid-range electric two-wheelers, such as E-Mopeds, which offer moderate performance, are priced similarly to manual motorbikes, the most popular model in Vietnam. Within the same segment, E2Ws offer better economic performance for owners compared to their ICE counterparts over time due to its lower fuel and maintenance costs accumulate and offset the battery replacement expenses. The analysis in this study indicates that while E2Ws are cost-effective for short-range travel, their economic viability diminishes with increasing travel distance due to lower fuel and maintenance costs accumulate and offset the battery replacement expenses. This underscores the need for targeted incentives and technological advancements to make E2Ws more competitive for broader use cases. Moreover, higher battery capacity helps reduce operating costs, significantly impacting the reduction of their TCO.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101742"},"PeriodicalIF":4.4,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the exact photovoltaic potential and determining the percentage of rooftop space required to achieve solar sufficiency at a national scale are vital yet underexplored areas of research. This study evaluates the photovoltaic potential of building rooftops and inland water bodies in Pakistan, focusing on their contribution to national solar sufficiency. The research encompasses the estimation of annual rooftop solar energy potential, analysis of electricity consumption patterns, determination of the required rooftop area to achieve solar sufficiency, multicriteria decision analysis for floating PV systems, and an assessment of carbon mitigation benefits. While achieving complete self-sufficiency through rooftop PV alone may be challenging, this study provides critical data to assess its feasibility and contribution to Pakistan's energy mix. Utilizing machine learning regression and geospatial techniques, the study evaluated electricity consumption, total rooftop PV potential, the required rooftop area for solar sufficiency, and the associated carbon reduction potential at a 1 km² grid resolution. Additionally, the FPV potential was assessed at a 30-m pixel resolution. Among the evaluated models, Random Forest demonstrated the highest predictive accuracy, achieving an R-squared value of 0.92. The results reveal that Pakistan's annual electricity consumption is 132.6 TWh, while its maximum RPV and FPV potentials are 310.1 TWh and 59.23 TWh, respectively. These potentials could reduce emissions by 192.3 MtCO₂e and 36.7 MtCO₂e annually.

As EVs have gained prominence globally, the volume of research on this subject has increased. However, previous review studies have not focused on examining trends in research that estimates the TCO for all types and technologies of EVs. Thus, our study aims to fill this gap by reviewing global trends and results of TCO studies on EVs. Our review employs the method of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to systematically collect and analyse 185 articles from 2011 to 2024. The contributions of our review are fourfold. Firstly, we construct a thematic research map to understand which topics are densely connected, thereby highlighting the core themes and focal points of the research field. As a result, future research should focus on reducing the TCO to accelerate EV adoption. Secondly, we show that the most extensively analysed vehicle technologies are battery electric vehicles (BEVs), while passenger cars are the most studied vehicle type. Thirdly, we differentiate the objectives of the TCO studies, identifying motivation gaps among them. We found that the primary objectives of the reviewed studies are TCO comparisons, followed by battery size and powertrain designs, policy scenario analysis, and TCO model developments. Lastly, we provide the range of TCO estimates for different types and technologies of vehicles. The average TCO for BEVs is found to be higher than that for internal combustion engine vehicles (ICEVs) across passenger cars, buses, trucks, and cargo vans. Electric motorcycles, however, buck this trend, with their average TCO being slightly lower than that of conventional motorcycles.

These challenges stem from rigid market structures, outdated regulatory frameworks, and limited digital infrastructure, which together hinder the development of a flexible, decentralized energy model. This study assesses Panama's readiness for decentralized energy adoption using a structured five-step methodology that combines policy analysis, barrier identification, and comparative benchmarking with seven international case studies. These countries are grouped into gradual (Chile, Colombia, Mexico, Brazil) and advanced (Germany, Norway, Singapore) transition clusters. Applying evaluation criteria from IRENA and IEA, the study examines five key dimensions—regulatory framework, grid infrastructure, economic incentives, institutional coordination, and grid stability. The assessment positions Panama at Low to Medium readiness, constrained by minimal digitalization, limited demand-side flexibility, and regulatory misalignment with emerging decentralized technologies. To address these gaps, a phased policy roadmap is proposed, focusing on regulatory modernization, smart grid deployment, and stakeholder coordination. The roadmap also integrates key socioeconomic considerations—including employment generation, equitable access to prosumer models, and electricity affordability—as structural elements of a just transition. This strategy aims to facilitate the integration of electric vehicles and distributed solar generation while safeguarding grid stability and preserving Panama's carbon-negative balance. The findings offer a replicable framework for developing countries with similar market rigidities, demonstrating how phased, context-specific reforms can unlock the benefits of decentralized energy while supporting long-term sustainability, energy resilience, and inclusive development.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101747"},"PeriodicalIF":4.4,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143943285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
