To enable tractable, country-scale optimization, we adopt two complementary strategies: (i) a time-aggregated formulation assuming stable seasonal demand, and (ii) a spatial aggregation method based on agglomerative hierarchical clustering, which places retailers at distance-constrained geomedian points of rooftop clusters. We compare this clustering-based approach against a benchmark that uses village centroids for retailer siting, demonstrating cost savings and improved spatial fairness. Additionally, we assess the scalability of the system under projected demand growth and evaluate infrastructure–transportation trade-offs under fluctuating diesel prices.

Three interlinked models including life cycle carbon emission (LCCE) reduction, life cycle cost (LCC) increase, and energy consumption change were constructed, and four typical Chinese cities with distinct solar resource grades were selected for analysis. Key findings include: (1) SEVs significantly reduce the number of grid charges; for example, BEVs in Lhasa require 442 charges over 10 years, while SEVs only need 83 charges (81.2% reduction). (2) Power battery capacity reduction (20%–30%) balances environmental and economic benefits, and at 20% reduction (Lhasa) or 30% reduction (Chengdu), SEVs' LCC increase shifts from positive to negative. (3) Under similar numbers of charges, compared with BEVs, SEVs can reduce their power battery capacity by 50%–60%. (4) The LCC critical line (0 boundary) shifts upward with solar resource quality: at 25% VIPV efficiency, Lhasa tolerates an initial module cost of 500–600 CNY/m², while Chengdu only tolerates 200–300 CNY/m².

First, a diagnosis was conducted in four indigenous communities to understand the distances traveled, the types of vehicles used, and the reasons for mobility. Second, with the diagnostic data collected through household surveys and validated through experimental measurements, two future scenarios were modeled: a base scenario was projected for 2050 using consumption data to determine current and future energy, economic, and environmental impacts, and an alternative scenario was created to consider integrating hybrid and electric vehicles for public transportation, self-financing, and impact estimation. Finally, guidelines for developing transportation plans in Indigenous communities were outlined, considering a participatory approach. It was found that the activities requiring the longest distances traveled are related to entertainment, while those requiring the most frequent transfers are related to food supply, education, and work. Approximately 30% of the population in these communities needs motorized transportation daily, with average trips exceeding 18 km. The per-family energy demand for motorized mobility is below 5 GJ/year, and the inhabitants spend about 30% of their income on transportation services. Furthermore, annual emissions per community can reach up to 5000 t CO₂e. The scenarios proposed in this work could lead to significant energy and economic savings and emissions reductions of more than 20% considering hybrid vehicles, and more than 30% in the case of electric cars.

This widespread dependence underscores the urgent need for accurate measurement of biomass consumption and associated emissions. The primary objective of this study is to enhance the understanding of household biomass energy use by quantifying the contributions of woody biomass and crop residues, examining seasonal consumption patterns, and estimating the resultant CO₂e emissions. The study's novelty lies in its application of a digital, sensor-based system to continuously and accurately monitor biomass consumption across 420 households in Eastern Rwanda, conducted over three agricultural seasons. This approach generates high-resolution, region-specific data on the utilization of firewood, crop residues, and charcoal, while directly linking consumption patterns to CO₂e emissions. The findings indicate that firewood accounts for 86% of the total biomass used for cooking, followed by crop residues at 13% and charcoal at 0.8%. The estimated daily household consumption amounts to 3.1 kg of firewood, 0.47 kg of crop residues, and 0.03 kg of charcoal. The relatively high amount of crop residue suggests a chronic shortage of firewood, despite the intensive tree-planting campaigns. Firewood consumption remained stable during season A (short rainy) and season B (rainy), with a slight decrease in season C (dry). Crop residues decreased steadily from Season A to B, and further to C. The estimated annual CO_2e emission from biomass combustion is 1.32 tons per household and 0.48 tons per capita. Digital methods provide precise, time-resolved data on fuel types and consumption, offering valuable insights for energy planning and carbon financing. Future research should integrate PM₂.₅ emissions to better assess health impacts and determine the sustainable balance between using crop residues as fuel and returning them to the soil.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"92 ","pages":"Article 101951"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188742","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}

Time-resolved curves show that, under most conditions, ethanol production plateaus around 89 h, with only a small additional increase by 120 h; glucose is the main driver of early ethanol production, while xylose residue depends on specific conditions, and energy consumption increases linearly over time. Using responses at 89 h, NaOH loading emerges as the dominant pretreatment factor, and a moderate-severity region near ∼2 % NaOH, ∼120 °C, and ∼ 60 min balances solid recovery, fermentability, and energy-normalized productivity (ENP).

Carbon Capture, Utilization, and Storage (CCUS) technology is considered a key solution for such reductions. However, empirical studies on CCUS deployment in the cement industry remain limited. In order to achieve this, the study set three core target scenarios for overall emissions reductions in China's cement industry: 40%, 50%, and 60%. Following a thorough screening and evaluation of 2651 cement plants nationwide, a full-process CCUS source-sink matching optimisation model was constructed to determine the optimal deployment strategy under each emissions reduction scenario. The results indicate that meeting these targets requires a large-scale deployment, involving the retrofitting of over 400 to 500 cement plants. The model estimates the corresponding unit abatement costs to be in the range of approximately 320 to 380 CNY/t CO₂. Regional analysis revealed that the northeast has the lowest abatement costs, while the southwest incurs the highest. These findings suggest that differentiated development strategies should be formulated based on regional source-sink distribution and that cross-regional CCUS cooperation is essential to facilitate low-carbon transformation in the cement industry.

Using agricultural residues as feedstock for decentralised bioenergy systems could mitigate these impacts and help to achieve SDGs 7 (affordable and clean energy) and 13 (climate action). Using FAOSTAT and CROPGRIDS data, we mapped the spatial distribution and production volume of the most significant crop residues at high resolution. Residues were categorized by structure and composition in order to estimate biomethane yields and their compatibility with small-scale digesters or cookstoves. Deforestation priority regions were delineated using forest loss data derived from Landsat, enabling targeted analysis of bioenergy deployment in the most affected areas. Theoretical potential was calculated for small-scale digesters (5–15 m³) and household cookstoves based on local residue availability. Additional site-specific assessments were conducted for large-scale anaerobic digestion at over 50 poultry farms.
