In Ghana, only 0.4 % of households are estimated to cook primarily with electricity as of 2023. Meanwhile, biomass fuels dominate the cooking fuel landscape of both urban and peri-urban households in Ghana, compounding the household air pollution situation, which is one of the most critical health risk factors at present. The paper seeks to unpack empirically the evidence that counters the misconceptions around e-cooking among urban and peri-urban households in the Greater Accra Region and to assess their willingness to use and pay for e-cooking technologies. Two methodological approaches were employed to achieve these objectives. Firstly, standardized semi-controlled cooking tests were carried out with four local meals prepared using 4 fuel technologies. Secondly, a mixed method (quantitative and qualitative) approach was utilised, involving the survey of 1203 households from Adenta, Ga East, and Ga West Municipalities. The results revealed that at least 70 % of the households sampled perceived e-cooking to be more expensive than cooking with charcoal and LPG. However, the cooking experiment outcomes showed e-cooking to be far cheaper compared to cooking with charcoal and LPG. Households' willingness to use e-cooking technologies increased after they saw the results of the experiment. However, most of them demonstrated a lower willingness to pay values than the market value of the Electric Pressure Cooker due to lack of affordability. The enhancement of e-cooking technologies adoption will depend on a set of transformative initiatives by all stakeholders in the energy sector.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101773"},"PeriodicalIF":4.4,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297246","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}

The model is built with manually gathered country-specific data, made available in open-source, and validated against official national statistics. The model is then applied to Nigeria and South Africa to evaluate the impact of national transmission expansion and pumped hydro energy storage (PHES) on variable renewable energy (VRE) penetration. Our results highlight that strategic combinations of storage and grid enhancements can significantly increase renewable utilization, reduce curtailment, and lower emissions. While PHES is particularly effective in solar-dominated contexts, transmission expansion plays a crucial role in overcoming regional grid constraints, as observed in South Africa. The findings emphasize the importance of country-specific strategies for VRE integration and reinforce the role of infrastructure planning in achieving Sustainable Development Goal 7 (SDG7), particularly Target 7.2 on increasing the share of renewables, and how this can potentially have beneficial indirect effects on Target 7.1, universal access, and 7.3, increased efficiency. This work introduces a novel application of the Calliope framework tailored to African countries, combining high-resolution national models with a flexible scenario-based methodology to quantify the role of PHES and grid expansion. Unlike existing studies, it leverages open-access, validated data and focuses on less-explored storage options such as PHES rather than BESS, thus filling a methodological and thematic gap in the current literature. By demonstrating how different approaches shape renewable integration outcomes, this study provides a replicable methodology for policymakers and energy planners seeking cost-effective, resilient pathways towards decarbonization.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101760"},"PeriodicalIF":4.4,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271968","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}

The energy consumption is influenced by multiple factors, including operating parameters, energy utilization methods, and energy-saving technologies in steel enterprises, with its variation levels exhibiting complexity and regularity. However, the underlying mechanisms driving energy consumption fluctuations remain unclear, and there is a lack of real-time collaborative control strategies adapted to actual production scenarios. Moreover, the energy-saving potential of existing technologies and the energy-saving effects after technological retrofit remain uncertain. To address these challenges, this study develops an energy consumption simulation and diagnostic model based on both mechanism and data-driven approaches. The model simulates the fluctuation trends of energy consumption and identifies key influencing factors, thereby providing targeted operational optimization suggestions. Taking the coking process as a case study, a hierarchical diagnostic approach is applied to evaluate the energy consumption level by selecting the minimum energy consumption value for 30 days as the benchmark. The analysis identifies that the coal composition is the most effective controllable factor. Adjusting key coal parameters is expected to reduce energy consumption by 3.60 kgce/t. Furthermore, deploying new energy-saving technologies can further decrease energy consumption by 4.27 kgce/t.

However, Indonesia still relies heavily on coal and other fossil fuels for its energy needs, presenting obstacles to achieving this target. We explore the factors influencing Indonesia's NZE-related energy policy and the associated challenges by analysing relevant literature, as well as interviews and surveys conducted with the country's energy experts. Using a political economy framework for our analysis, we find that, despite recognising the adverse effects of climate change, Indonesia's energy policy continues to focus on meeting the energy demand for national development from conventional sources rather than shifting decisively towards cleaner energy. This focus is driven not only by the government's commitment to fulfilling energy demands but also by the influence of certain actors who actively promote their agendas. Indonesia's two main challenges to achieving NZE are institutional and technical. Institutional challenges include the lack of a comprehensive policy framework, insufficient funding, and inadequate coordination among government institutions. Technical challenges include reducing energy intensity, lowering emissions from electricity generation, decreasing emissions in key economic areas (transportation, industry, and households), adopting carbon capture technologies, and reducing energy poverty. To achieve net zero by 2060, Indonesia needs a legally binding policy with clear strategies to address these challenges in the energy transition. This policy should include support for private investments in clean energy projects, the reduction of fossil fuel subsidies, promoting renewable energy development, and improving energy efficiency.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101757"},"PeriodicalIF":4.4,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184800","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}

However, most studies on renewable energy site selection focus on individual technologies, often prioritizing a single energy source and failing to account for spatial variability across regions. Here, a novel framework is presented that addresses both site and source selection for distributed renewable energy infrastructure, guided by the principle of resource sustainability. The resource sustainability of small hydropower (SHP), onshore wind power, and rooftop solar photovoltaics (PVs) was compared, and integrated preferential areas were demonstrated. Firstly, the power generation potential of these technologies was estimated, and then their resource sustainability was compared using the resources time footprint (RTF) in terms of materials, CO₂ emissions, land, and labor. The preferential areas for these technologies by applying RTF have been identified as a case study in Fujian, China.

The potential of SHP and onshore wind power to reduce CO₂ emissions is higher than that of solar PV systems. The land occupancy of SHP is greater than that of wind power. ∆RTF of labor is the largest for SHP, followed by wind power and solar PV. Wind power has the smallest average overall ∆RTF (−44.38 years), compared with SHP (−30.38 years) and solar PVs (46.38 years), indicating that wind energy is the most sustainable in the study area.

Mini-grids are a key off-grid alternative, but their implementation is hampered by early abandonment. This leads to stranded assets, ineffective use of public funds, and reduced investment in rural electrification. This study aims to identify strategies for repurposing abandoned mini-grids. Through a qualitative assessment of abandoned cases, technical failure and main grid arrival were identified as the primary reasons behind this issue. While technical failure must be addressed through preventive measures to avoid interruptions in electricity supply, repurposing strategies can enhance the use of abandoned assets after grid encroachment. An economic analysis of two case studies—a 15 kW micro-hydro power (MHP) mini-grid in Nepal and a 50 kWp solar photovoltaic (PV) mini-grid in Mali—revealed that the viability of these strategies is context-specific. This was complemented by a sensitivity analysis of key parameters. In Nepal, the current situation does not encourage the repurposing of small-scale mini-grids, having a maximum Levelized Profit of Electricity (LPOE) of 0.13 €ct/kWh for post-interconnection. In other scenarios, green hydrogen production reaches an LPOE of up to 10.32 €ct/kWh under favourable investment costs and hydrogen price conditions. In Mali, post-interconnection options are cost-effective due to the tariff levels and low interconnection costs, with a current LPOE of 5.09 €ct/kWh and a maximum value of 8.80 €ct/kWh. These findings underscore the importance of national policies and regulatory frameworks in supporting the repurposing of mini-grids.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101762"},"PeriodicalIF":4.4,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147427","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}
