We examine how technical characteristics influence firms' decisions to adopt natural gas as an alternative fuel in their production processes. Using firm-level data, we first identify key drivers of adoption through probit models, highlighting the roles of heating equipment, cost competitiveness, and prior knowledge of natural gas. To extend the analysis, we apply LASSO regression to incorporate a wider set of predictors, including infrastructure access, retrofitting costs, electricity source, environmental awareness, and firm characteristics. Our results show that proximity to fueling or regasification stations is strongly associated with a higher probability of adoption, while high retrofitting costs show a robust negative correlation. Firms reliant on major grid-based electricity providers or familiar with renewable energy sources are less open to switching, suggesting perceived reliability of existing energy sources or a preference for technologies more directly aligned with renewable commitments. Conversely, firm-level familiarity with natural gas consistently exhibits a positive and significant association with adoption. We observe moderate heterogeneity in openness to switch to natural gas across firm types, with the highest propensity among those using heating equipment in core operations. These findings emphasize the importance of infrastructure access, technical knowledge, and financial constraints in shaping the transition to cleaner fuels in industrial sectors. We highlight the “renewable energy commitment effect,” which is the reluctance to switch to a fuel less committed to renewables.

我们研究了技术特征如何影响企业在生产过程中采用天然气作为替代燃料的决策。利用公司层面的数据，我们首先通过probit模型确定了采用该技术的关键驱动因素，强调了供暖设备、成本竞争力和天然气先验知识的作用。为了扩展分析，我们应用LASSO回归来纳入更广泛的预测因素，包括基础设施获取、改造成本、电力来源、环境意识和企业特征。我们的研究结果表明，靠近加氢站或再气化站与更高的采用概率密切相关，而高改造成本则表现出强烈的负相关。依赖主要电网供电供应商或熟悉可再生能源的公司不太愿意转换，这表明现有能源的可靠性或对更直接符合可再生能源承诺的技术的偏好。相反，公司层面对天然气的熟悉程度始终与采用率呈显著正相关。我们观察到，不同类型的公司在转向天然气的开放程度上存在适度的异质性，在核心业务中使用加热设备的公司中，倾向程度最高。这些研究结果强调了基础设施获取、技术知识和资金限制对工业部门向清洁燃料过渡的重要性。我们强调了“可再生能源承诺效应”，即不愿转向可再生能源承诺较少的燃料。

Transitioning public bus fleets to electric mobility requires large-scale deployment of electric bus charging stations (EBCSs) in depots. While essential for decarbonization, such infrastructure entails substantial upfront investments and grid reinforcement costs. Photovoltaic (PV) integration and smart charging strategies can help mitigate these challenges by lowering charging costs and smoothing charging demand. Another opportunity arises from idle chargers during the day, as most electric buses (EBs) rely on overnight charging. Making these chargers available to private electric vehicles (EVs) can transform depots into multifunctional charging hubs that both generate revenue and address the growing urban demand for fast charging.

This study develops an optimal configuration of a PV-assisted and charger-sharing EBCS for a bus depot in Istanbul, Türkiye. Simulations estimate the 25-year net present cost (NPC) at $24.5 million for the base case with depot-only overnight charging. Adding 2333 kW of PV with charging management reduces the NPC to $21.5 million. Expanding PV capacity to 4000 kW and enabling charger sharing with 250 private EVs per day further reduces the NPC to $10.1 million, a 58.8 % reduction. Notably, despite the addition of 250 EVs/day, peak demand remains stable (3488 kW versus 3467 kW), demonstrating that PV integration and charging management can prevent costly grid reinforcements even with added EV loads.

A cross-country comparison extends the analysis to Spain, Greece, Bulgaria, and Portugal, which have similar solar resources and electricity prices but higher EV charging fees. In these contexts, the proposed system can offset the full costs of PV and charging infrastructure, along with 25-year EB charging expenses.

The findings demonstrate that PV-assisted and charger-sharing bus depots can serve as dual-purpose infrastructure, simultaneously supporting sustainable fleet electrification and expanding urban fast-charging capacity. Given that high upfront costs remain the primary barrier to bus fleet electrification, these results offer valuable guidance for policymakers, operators, and energy planners. Furthermore, the proposed methodology is adaptable to different cities and depot configurations.

将公共巴士车队转变为电动交通需要在车站大规模部署电动巴士充电站（EBCSs）。虽然对脱碳至关重要，但这种基础设施需要大量的前期投资和电网加固成本。光伏（PV）集成和智能充电策略可以通过降低充电成本和平滑充电需求来帮助缓解这些挑战。另一个机会来自于白天空闲的充电器，因为大多数电动公交车（EBs）依赖于夜间充电。将这些充电器提供给私人电动汽车（ev）可以将仓库转变为多功能充电中心，既能产生收入，又能满足城市对快速充电日益增长的需求。本研究为土耳其伊斯坦布尔的一个公交车站开发了一个pv辅助和充电器共享的EBCS的最佳配置。模拟结果显示，仅在车场过夜充电的基本情况下，25年的净现值成本（NPC）为2450万美元。增加2333千瓦的光伏和充电管理将使NPC减少到2150万美元。将光伏发电容量扩大到4000千瓦，并允许每天250辆私人电动汽车共享充电器，进一步将NPC减少到1010万美元，减少58.8%。值得注意的是，尽管每天增加了250辆电动汽车，但峰值需求保持稳定（3488千瓦对3467千瓦），这表明即使增加了电动汽车负荷，光伏集成和充电管理也可以防止昂贵的电网加固。一项跨国比较将分析扩展到西班牙、希腊、保加利亚和葡萄牙，这些国家的太阳能资源和电价相似，但电动汽车充电费用更高。在这种情况下，拟议的系统可以抵消光伏和充电基础设施的全部成本，以及25年的电动汽车充电费用。研究结果表明，光伏辅助和充电器共享的公交车站可以作为双重用途的基础设施，同时支持可持续的车队电气化和扩大城市快速充电容量。鉴于高昂的前期成本仍然是公交车队电气化的主要障碍，这些研究结果为政策制定者、运营商和能源规划者提供了有价值的指导。此外，所提出的方法适用于不同的城市和仓库配置。

Hydrokinetic energy offers significant potential to support India's goal of achieving net zero carbon emissions by 2070, as outlined at COP26. The study evaluates techno-economic viability of deploying a hydrokinetic farm along a 1 km canal in Uttarakhand, India, using helical Savonius turbines with diameters (D) of 0.25 m (case 1), 0.50 m (case 2), 0.75 m (case 3), and 1.0 m (case 4). Numerical model used in the investigation has been validated experimentally. The developed model evaluates power generation capacity and key financial indicators, including Net present value (NPV), Internal rate of return (IRR), Payback period (PP), and Levelized cost of energy (LCOE). Sensitivity analyses have been conducted using varying capital expenditure (CapEx), operation and maintenance (O&M) costs, discount rate, and electricity selling price. The optimal turbine spacing is estimated as 39D to 41D longitudinally and 6D laterally, at a flow velocity of 2.5 m/s and tip speed ratio of 0.9 for 0.25 m to 1.0 m diameter turbine. The estimated farm installed capacities are 0.40 MW, 0.42 MW, 0.41 MW, and 0.39 MW for cases 1 through 4, respectively, with larger turbines demonstrating superior economic feasibility. Case 4 emerges as the most favourable, with NPV: US$ 0.136 million, IRR: 14.16 %, PP: 6.64 years, LCOE: US$ 0.060/kWh. Sensitivity analysis highlights that CapEx and electricity price are the most influential parameters, whereas O&M cost has minimal impact. The findings suggest that with technological advancements, favourable policies, and large-scale deployment, hydrokinetic technology will become less risky and more competitive with established renewable energy technologies.

正如COP26所概述的那样，水动能为支持印度到2070年实现净零碳排放的目标提供了巨大的潜力。该研究评估了在印度北阿坎德邦沿1公里运河部署水动力农场的技术经济可行性，使用直径(D)为0.25米（案例1）、0.50米（案例2）、0.75米（案例3）和1.0米（案例4）的螺旋Savonius涡轮机。所采用的数值模型已得到实验验证。该模型评估了发电能力和主要财务指标，包括净现值（NPV）、内部收益率（IRR）、投资回收期（PP）和能源平准化成本（LCOE）。使用不同的资本支出（CapEx）、运营和维护（O&；M）成本、贴现率和电力销售价格进行了敏感性分析。对于直径为0.25 m ~ 1.0 m的涡轮，在流速为2.5 m/s，叶尖速比为0.9的条件下，涡轮纵向间距为39D ~ 41D，横向间距为6D。案例1至案例4的装机容量分别为0.40兆瓦、0.42兆瓦、0.41兆瓦和0.39兆瓦，其中较大的涡轮机显示出更好的经济可行性。案例4是最有利的，NPV: 13.6万美元，IRR: 14.16%, PP: 6.64年，LCOE: 0.060美元/千瓦时。敏感性分析表明，资本支出和电价是影响最大的参数，而运营管理成本的影响最小。研究结果表明，随着技术的进步、有利的政策和大规模部署，水动力技术将变得风险更小，与现有的可再生能源技术相比更具竞争力。

In response to climate change, China has set ambitious carbon neutrality targets. As the nation's capital, Beijing holds a crucial position in leading carbon reduction initiatives for other cities. Therefore, it is important to investigate Beijing's carbon emission reduction pathways. The mainstream modeling approaches that are used in existing research mostly concentrate on energy system models. Although energy system models are widely used for carbon reduction pathways purpose, existing studies often lack a systematic assessment of whether proposed pathways align with local carbon budgets under climate targets. Moreover, their reliance on low temporal resolutions, such as annual scales in long-term planning, fails to capture the essential physical characteristic of the power system: the real-time balance between generation and load. These shortcomings not only hinder the smooth achievement of climate change goals but also tend to underestimate power security risks, thereby reducing the feasibility of long-term emission reduction plans. In order to address this issue, we developed an integrated LEAP-DICE-BJ model, which combines a bottom-up energy system model with a top-down climate-economy model. Employing the LEAP-DICE-BJ model, this study conducts a cost optimization study on carbon budgets, carbon emission reduction pathways, and power generation capacity planning under the constraint of the 2 °C climate target. The conclusion reveals that Beijing must initiate the energy transition as early as possible, and no later than 2027.In terms of construction priorities, in the early stages focus should be put on the construction of transmission lines for importing green electricity and developing wind power. In the mid-stages, distributed solar PV should be emphasized. In the later stages, energy storage should be developed to achieve zero emissions while ensuring power security through natural gas plants. By 2060, Beijing's power mix will primarily consist of imported green electricity, distributed solar PV, and energy storage, complemented by biomass, wind, and hydropower. Imported thermal power and local natural gas plants will provide capacity support in a diversified energy mix. Building on these findings, specific recommendations are provided.

为应对气候变化，中国制定了雄心勃勃的碳中和目标。作为中国的首都，北京在引领其他城市的碳减排行动方面处于至关重要的地位。因此，研究北京市碳减排路径具有重要意义。现有研究中使用的主流建模方法大多集中在能源系统模型上。尽管能源系统模型被广泛用于碳减排途径的研究，但现有的研究往往缺乏对所提出的途径是否与气候目标下的地方碳预算相一致的系统评估。此外，它们对低时间分辨率的依赖，如长期规划中的年度尺度，未能捕捉到电力系统的基本物理特征：发电和负荷之间的实时平衡。这些缺点不仅阻碍了气候变化目标的顺利实现，而且容易低估电力安全风险，从而降低了长期减排计划的可行性。为了解决这个问题，我们开发了一个综合的LEAP-DICE-BJ模型，它将自下而上的能源系统模型与自上而下的气候经济模型相结合。本研究采用LEAP-DICE-BJ模型，对2°C气候目标约束下的碳预算、碳减排路径和发电容量规划进行了成本优化研究。结论表明，北京必须尽早启动能源转型，最迟不迟于2027年。从建设重点上看，前期重点建设绿色电力输电线和发展风电输电线。在中期，应强调分布式太阳能光伏。在后期阶段，应发展储能，以实现零排放，同时通过天然气发电厂确保电力安全。到2060年，北京的电力结构将主要由进口绿色电力、分布式太阳能光伏和储能组成，并辅以生物质能、风能和水力发电。进口火电和本地天然气厂将为多元化的能源结构提供产能支持。在这些调查结果的基础上，提出了具体建议。

Africa hosts approximately 14 million refugees; nearly one-third of the global refugee population. Uganda alone hosts over 1.8 million refugees, with their settlement on small plots of land (~ 50 × 50 m), within host communities exerting pressure on natural resources and accelerating environmental degradation. This paper presents a study on the root causes and consequences of woodfuel sourcing and utilization and community priority interventions in Rhino and Imvepi Refugee Settlements in Uganda for informed decision making. Data was collected via a household survey through personal communication with 381 respondents (62 men, 319 women), key informant interviews (KIIs) and focus group discussions (FGDs). The results showed that firewood was the dominant fuel used by 96 % of hosts and 97 % of refugees, followed by charcoal (40 % and 59 %, respectively). Fuel stacking (using more than one fuel type) was reported by 48 % of hosts and 73 % of refugee households. Our study highlights that refugees presented greater reliance on charcoal and crop residues, reflecting firewood scarcity and charcoal's availability as a traded commodity. Women and children, particularly among refugees, faced greater hardships in accessing firewood. Environmental degradation from woodfuel sourcing and utilization is driven by socio-cultural norms, economic hardship, weak policy enforcement and inadequate skills and poor awareness of sustainable practices; leading to deforestation, air pollution, soil degradation, biodiversity loss and adverse impacts on livelihoods. The root causes and impacts from woodfuel sourcing and use are complex and deeply interconnected, highlighting the need for transdisciplinary, gender-responsive and context-specific approaches to promote sustainable and cleaner woodfuel systems in both host and refugee communities.

非洲收容了大约1400万难民；占全球难民人口的近三分之一。仅乌干达就收容了180多万难民，他们居住在收容社区内的小块土地上（约50 × 50米），对自然资源造成压力，加速了环境退化。本文介绍了一项关于乌干达Rhino和Imvepi难民定居点木材燃料采购和利用的根本原因和后果以及社区优先干预措施的研究，以促进知情决策。通过与381名受访者（62名男性，319名女性）的个人沟通、关键信息提供者访谈（KIIs）和焦点小组讨论（fgd）的家庭调查收集数据。结果显示，96%的收容人和97%的难民使用木柴作为主要燃料，其次是木炭（分别为40%和59%）。48%的东道国和73%的难民家庭报告了燃料堆放（使用一种以上的燃料类型）。我们的研究强调，难民对木炭和作物残留物的依赖程度更高，这反映了木柴的稀缺和木炭作为一种贸易商品的可用性。妇女和儿童，特别是难民中的妇女和儿童，在获得柴火方面面临更大的困难。社会文化规范、经济困难、政策执行不力、技能不足和对可持续做法认识不足造成木质燃料采购和利用造成的环境退化；导致森林砍伐、空气污染、土壤退化、生物多样性丧失以及对生计的不利影响。木材燃料的来源和使用的根本原因和影响是复杂和深刻相互关联的，突出表明需要采取跨学科、顾及性别和具体情况的办法，在收容社区和难民社区促进可持续和更清洁的木材燃料系统。

The rapid and widespread implementation of renewable energy (RE) systems across various sectors is vital to mitigating global warming. This study synthesizes insights from 270 peer-reviewed articles published over the past decade, examining the social, economic, and environmental impacts of RE technologies. It highlights recurring themes, challenges, opportunities, and divergences in findings shaped by regional and contextual factors. Social dimensions—particularly trust in institutions and the quality of governance—emerge as key enablers of RE adoption. The concept of place attachment also receives attention, although its role remains contested, with studies divided on whether it facilitates or obstructs RE initiatives. Economically, while the global agenda favors sustainable energy, many developed and developing countries continue to prioritize fossil fuel development for economic growth. Environmentally, much of the literature focuses on the localized negative impacts of RE projects, often underemphasizing their broader climate mitigation benefits. Additionally, there is a significant lack of research on the environmental implications of RE deployment in low-income countries. Two critical research gaps are identified: the need to further explore the benefits of co-locating RE infrastructure in developing economies and the importance of integrating First Nations perspectives and active participation in RE research and project planning.

在各个部门迅速和广泛地实施可再生能源（RE）系统对于减缓全球变暖至关重要。本研究综合了过去十年发表的270篇同行评议文章的见解，研究了可再生能源技术的社会、经济和环境影响。它强调了反复出现的主题、挑战、机遇以及受区域和背景因素影响的研究结果的差异。社会层面——特别是对机构的信任和治理质量——成为采用可再生能源的关键推动因素。地点依恋的概念也受到了关注，尽管它的作用仍然存在争议，关于它是促进还是阻碍RE倡议的研究存在分歧。在经济上，虽然全球议程支持可持续能源，但许多发达国家和发展中国家继续将化石燃料开发作为经济增长的优先事项。在环境方面，许多文献侧重于可再生能源项目的局部负面影响，往往低估了其更广泛的气候缓解效益。此外，对低收入国家部署可再生能源的环境影响的研究明显缺乏。确定了两个关键的研究缺口：需要进一步探索在发展中经济体共同安置可再生能源基础设施的好处，以及整合原住民观点和积极参与可再生能源研究和项目规划的重要性。
