Participatory practices and social innovations are recognised as important for sustainable renewable energy projects. However, information on the significance of diverse participatory practices and social innovations for advancing inclusive and sustainable wind energy developments remains limited. To address this gap, this study aims to understand how diverse participatory practices in wind energy developments across the globe influence energy justice differently. It does so, by analysing how a fairer participation of communities is interconnected to the models of participation while investigating how participatory practices interrelate with social innovations. Drawing on the ‘ecologies of participation’ approach, the work compiles a dataset of 312 case studies of collective participatory practices in wind energy projects, of which 209 are classified as social innovation projects. Findings indicate that not all participatory practices and social innovations are equal in ensuring just processes in wind energy governance. This requires careful consideration of different aspects of participation (e.g., opportunities provided, continuity of the process) and adherence to principles of justice in wind energy governance (e.g., inclusivity, capacity to influence, transparency). Conclusions highlight that fairer participation practices are interconnected to both the models of participation and to the wider spaces of participation in which they are embedded.

参与性实践和社会创新被认为对可持续可再生能源项目非常重要。然而，有关多元化参与实践和社会创新对推进包容性和可持续风能发展的重要意义的信息仍然有限。为了弥补这一不足，本研究旨在了解全球风能开发中的各种参与性实践如何对能源公正产生不同的影响。为此，本研究分析了更公平的社区参与如何与参与模式相互关联，同时调查了参与实践与社会创新之间的相互关系。根据 "参与生态学 "方法，该研究汇编了 312 个风能项目集体参与实践的案例研究数据集，其中 209 个被归类为社会创新项目。研究结果表明，并非所有的参与实践和社会创新都能确保风能治理过程的公正性。这需要仔细考虑参与的不同方面（如提供的机会、过程的连续性），并遵守风能治理的公正原则（如包容性、影响能力、透明度）。结论强调，更公平的参与实践既与参与模式相互关联，也与它们所处的更广泛的参与空间相互关联。

Studies estimating the production cost of hydrogen-based fuels, known as e-fuels, often use renewable power profile time series obtained from open-source simulation tools that rely on meteorological reanalysis and satellite data, such as Renewables.ninja or PVGIS. These simulated time series contain errors compared to real on-site measured data, which are reflected in e-fuels cost estimates, plant design, and operational performance, increasing the risk of inaccurate plant design and business models. Focusing on solar-powered e-fuels, this study aims to quantify these errors using high-quality on-site power production data. A state-of-the-art optimization techno-economic model was used to estimate e-fuel production costs by utilizing either simulated or high-quality measured PV power profiles across four sites with different climates. The results indicate that, in cloudy climates, relying on simulated data instead of measured data can lead to an underestimation of the fuel production costs by 36 % for a hydrogen user requiring a constant supply, considering an original error of 1.2 % in the annual average capacity factor. The cost underestimation can reach 25 % for a hydrogen user operating between 40 % and 100 % load and 17.5 % for a fully flexible user. For comparison, cost differences around 20 % could also result from increasing the electrolyser or PV plant costs by around 55 %, which highlights the importance of using high-quality renewable power profiles. To support this, an open-source collaborative repository was developed to facilitate the sharing of measured renewable power profiles and provide tools for both time series analysis and green hydrogen techno-economic assessments.

估算氢基燃料（即电子燃料）生产成本的研究通常使用从开源模拟工具（如 Renewables.ninja 或 PVGIS）获得的可再生能源功率曲线时间序列，这些工具依赖于气象再分析和卫星数据。这些模拟时间序列与真实的现场测量数据相比存在误差，这些误差反映在电子燃料的成本估算、发电厂设计和运行性能中，增加了发电厂设计和商业模式不准确的风险。本研究以太阳能发电的电子燃料为重点，旨在利用高质量的现场发电数据量化这些误差。该研究采用了最先进的优化技术经济模型，利用四个不同气候条件下的模拟或高质量测量光伏发电曲线来估算电子燃料的生产成本。结果表明，在多云的气候条件下，对于需要持续供应燃料的氢气用户来说，依靠模拟数据而不是测量数据会导致燃料生产成本被低估 36%，考虑到年平均发电量系数的原始误差为 1.2%。对于在 40% 至 100% 负载之间运行的氢气用户，成本低估可达到 25%，对于完全灵活的用户，成本低估可达到 17.5%。相比之下，如果将电解槽或光伏电站的成本增加约 55%，也会造成约 20% 的成本差异，这凸显了使用高质量可再生能源的重要性。为此，我们开发了一个开源协作资源库，以促进共享测量的可再生能源功率曲线，并为时间序列分析和绿色氢能技术经济评估提供工具。

Understanding the efficiency dynamics of green innovations is essential for advancing sustainable economic systems. This study evaluates the efficiency of forty-two countries in producing and utilizing green innovations for clean energy production and in achieving sustainable development goals from 2000 to 2020. Employing a network bias-corrected data envelopment analysis (DEA) and Malmquist productivity analysis, this study explores the adoption of green technology and its effects on economic and environmental efficiency. Findings reveal limited progress in clean energy efficiency across most countries, indicating suboptimal use of green innovations for the goals of affordable and clean energy and climate action). The results show that the efficiency pattern of green innovations follows a U-shaped curve, with initial inefficiencies followed by long-term gains. South American nations and the European Union demonstrate strong performance in integrating green technologies. However, green innovations alone appear insufficient; supportive policies, such as green taxes on emissions and renewable energy initiatives, are crucial for enhancing impact and achieving environmental sustainability.

了解绿色创新的效率动态对于推进可持续经济体系至关重要。本研究评估了 42 个国家从 2000 年到 2020 年在生产和利用绿色创新技术生产清洁能源以及实现可持续发展目标方面的效率。本研究采用网络偏差校正数据包络分析法（DEA）和 Malmquist 生产率分析法，探讨了绿色技术的采用及其对经济和环境效率的影响。研究结果表明，大多数国家在清洁能源效率方面取得的进展有限，这表明在实现负担得起的清洁能源和气候行动的目标方面，对绿色创新的利用还不够理想。）研究结果表明，绿色创新的效率模式呈 U 型曲线，最初效率低下，随后长期收益。南美国家和欧盟在整合绿色技术方面表现突出。然而，仅有绿色创新似乎还不够；支持性政策，如绿色排放税和可再生能源倡议，对于增强影响和实现环境可持续性至关重要。

The rapid growth of fast fashion has led to a thriving secondhand clothing market over the past decade, presenting both challenges and opportunities for sustainable energy practices in the fashion industry. However, the diverse stances adopted by developing countries on importing secondhand clothing, due to potential environmental threats and impacts on local garment manufacturing, have made international trade relationships increasingly sensitive and fragile. This study employs complex trade network analysis and temporal exponential random graph model to comprehensively analyze the dynamic evolution and driving factors of the global secondhand clothing trade network (GSCTN) from 1995 to 2022, with a focus on its implications for energy consumption and sustainability. The findings reveal consistent growth and significant expansion in the GSCTN, with developed countries like the United States, United Kingdom, and Germany remaining major exporters, while African countries such as Ghana and Kenya have become primary importers. Notably, Africa's import sources have gradually shifted from Europe to Asia, underscoring a trend of regionalization that may impact transportation-related energy consumption. The formation and evolution of the GSCTN are shaped by its endogenous structure, including delayed reciprocity, transitivity, and stability, as well as factors like environmental regulations, industrialization levels, and the fast fashion industry. Moreover, countries with colonial ties or regional trade agreements are more likely to engage in secondhand clothing trade. These findings provide valuable insights for policymakers to develop effective strategies that promote sustainable trade practices, support the transition towards a circular economy, and enhance energy efficiency in the fashion industry.

在过去十年中，快速时尚的快速增长带动了二手服装市场的蓬勃发展，为时尚产业的可持续能源实践带来了挑战和机遇。然而，由于潜在的环境威胁和对当地服装制造业的影响，发展中国家对进口二手服装采取了不同的立场，这使得国际贸易关系变得越来越敏感和脆弱。本研究采用复杂贸易网络分析和时间指数随机图模型，全面分析了 1995 年至 2022 年全球二手服装贸易网络（GSCTN）的动态演变和驱动因素，重点分析了其对能源消耗和可持续发展的影响。研究结果显示，全球二手服装贸易网络持续增长并大幅扩张，美国、英国和德国等发达国家仍是主要出口国，而加纳和肯尼亚等非洲国家已成为主要进口国。值得注意的是，非洲的进口来源已逐渐从欧洲转向亚洲，这表明区域化趋势可能会影响与运输相关的能源消耗。全球运输网络的形成和演变受其内生结构的影响，包括延迟互惠性、传递性和稳定性，以及环境法规、工业化水平和快速时尚产业等因素。此外，与殖民地有联系或签订了区域贸易协定的国家更有可能从事二手服装贸易。这些发现为政策制定者提供了宝贵的见解，有助于他们制定有效的战略，促进可持续贸易实践，支持向循环经济转型，提高时尚产业的能源效率。

Hydropower remains a crucial renewable energy source, playing a significant role in global electricity generation and the reduction of greenhouse gas emissions. However, climate change introduces substantial challenges to its sustainable development and operational resilience. This review offers a detailed analysis of the global impacts of climate change on hydropower systems, focusing on key mechanisms such as changes in precipitation patterns, temperature fluctuations, and extreme weather events. The review reveals varied regional impacts, with some regions experiencing increased water availability while others face significant reductions. It highlights the necessity for region-specific adaptive strategies, advanced forecasting methods, and technological advancements to bolster hydropower resilience. Furthermore, it stresses the importance of strong governance structures, inclusive policy frameworks, and the integration of hydropower with other renewable energy sources to establish a diverse and resilient energy portfolio. Despite progress, significant gaps remain, especially in incorporating socio-economic factors and land use changes into hydropower planning. Future research should aim to refine climate models, enhance infrastructure resilience, and explore synergies with other renewable energy sources. Addressing these issues will enable hydropower to continue contributing significantly to global renewable energy strategies, ensuring sustainable and reliable energy production amid a changing climate.

Electricity generation from wind energy is one of the main drivers of decarbonization in energy systems. However, installing wind farm facilities may have beneficial and harmful impacts on the habitat of living beings. This study reviews the literature based on economic analysis to identify the main externalities related to the installation of wind farms and the economic methodologies used to assess these externalities, filling an existent literature gap. A systematic literature review followed the Preferred Reporting Items on Systematic Reviews and Meta-analysis standards. A total of 33 studies were identified, most of them carried out in Europe. The studies cover 24 years, between 1998 and 2022. The externalities associated with wind electricity generation are classified into three categories: the impact on well-being, the impact of wind turbines, and the impacts of avoided externalities. Most studies (24 out of 33) determine economic values by stated preference methods through choice experiments, discrete choice experiments, and contingent valuation.

风能发电是能源系统去碳化的主要驱动力之一。然而，安装风电场设施可能会对生物栖息地产生有利和有害的影响。本研究在经济分析的基础上对文献进行了综述，以确定与安装风力发电场相关的主要外部效应以及用于评估这些外部效应的经济方法，从而填补现有文献空白。系统性文献综述遵循《系统性综述和元分析首选报告项目》标准。共确定了 33 项研究，其中大部分在欧洲进行。研究时间跨度为 24 年，即 1998 年至 2022 年。与风力发电相关的外部效应分为三类：对福祉的影响、风力涡轮机的影响以及避免外部效应的影响。大多数研究（33 项中的 24 项）通过选择实验、离散选择实验和或然估价等陈述偏好法确定经济价值。有 5 项研究采用了显性偏好方法，使用了对冲定价和旅行成本技术。此外，还讨论了外部性识别及其评估方面的挑战和局限性，并得出结论：由于最新的审查研究发表于 2016 年和 2017 年，因此需要更多更新的审查研究。此外，该报告还为政策制定者和学术界提供了一种更完整的评估去碳化影响的方法，除了技术视角外，该方法还考虑并估算了社会经济和环境视角。

The Fit for 55 package has significantly reduced CO₂ emissions from combustion propulsion sources. Therefore, it is considered important to maintain the efficiency of drive units at the required level. One of the main causes of changes in this area is the failure of the power system. This study focuses on the diagnosis of the gas injector, where the Gauss characteristic figure area method was used. The choice of the method was due to its analytical approach, which is different from the commonly used ones, and its easy interpretation of the results. However, the Gauss method was found to lack sensitivity in certain areas. Hence the proposal to supplement it with a trend line, which is a novelty of the study. The trend line, and in fact its indicators, allowed for improved inference relative to the original Gauss approach. This eliminated the fact of equivalent fields of figures that are rotated or distorted. The trend line indicators accurately identified the position of the characteristic figure and its shape. To confirm the expediency of using the proposed approach, tests were carried out for injectors: brand-new, in-operation, end-of-life and remanufactured, as well as those with artificially simulated deficiencies. The test results and analysis presented in the paper can be useful for further work, but also as a guideline for supplementing existing test stands with the described diagnostic functions. The proposed innovative approach was used for the case of gas injectors, but it is possible to apply it to testing injectors of other fuels.

Fit for 55 套餐大大减少了燃烧推进源的二氧化碳排放量。因此，将驱动装置的效率保持在要求的水平上被认为是非常重要的。造成这方面变化的主要原因之一是动力系统故障。本研究侧重于燃气喷射器的诊断，其中使用了高斯特征图面积法。之所以选择这种方法，是因为它的分析方法不同于常用的方法，而且易于解释结果。然而，高斯方法在某些方面缺乏灵敏度。因此，建议用趋势线作为补充，这也是本研究的一个新颖之处。与最初的高斯方法相比，趋势线及其指标能够改进推理。这消除了旋转或扭曲图形的等效区域的事实。趋势线指标准确地确定了特征图形的位置及其形状。为了证实使用建议方法的便利性，对全新、运行中、报废和改装的喷油器以及人为模拟缺陷的喷油器进行了测试。论文中介绍的测试结果和分析有助于进一步的工作，同时也可作为指导，为现有测试台补充所描述的诊断功能。所提出的创新方法用于燃气喷射器，但也可用于其他燃料喷射器的测试。

The increased participation of variable renewable energy sources (VREs) in electrical matrices worldwide is essential for achieving several United Nations Sustainable Development Goals (SDGs), such as SDGs 7 (Affordable and Clean Energy) and 13 (Climate Action). However, it brings several challenges to the planning and operation of power systems, mainly due to the intermittency of VREs. In this context, the complementary effects between different intermittent resources have garnered growing attention in the literature since such properties offer a collective capability to capture the stochastic nature of intermittent power generation when simulating scenarios. This work proposes a stochastic simulation model of renewable energy generation that explores several complementary effects between wind and photovoltaic resources in different Brazilian locations. The approach considers calculating energy generation states to simultaneously represent the generation of multiple renewable sources and using probability transition matrices based on historical data. The synthetic time series are subsequently assessed using statistical methods that indicate good adherence of the generated scenarios to most stylized facts of the historical series.

可变可再生能源（VREs）在全球电力矩阵中的参与度不断提高，这对于实现若干联合国可持续发展目标（SDGs）至关重要，例如可持续发展目标 7（负担得起的清洁能源）和 13（气候行动）。然而，这也给电力系统的规划和运行带来了一些挑战，主要是由于可再生能源的间歇性。在这种情况下，不同间歇性资源之间的互补效应在文献中受到越来越多的关注，因为这种特性提供了一种集体能力，可以在模拟情景时捕捉间歇性发电的随机性。本研究提出了一种可再生能源发电的随机模拟模型，探讨了巴西不同地区风能和光伏资源之间的几种互补效应。该方法考虑计算能源发电状态，以同时代表多种可再生能源的发电量，并使用基于历史数据的概率转换矩阵。随后使用统计方法对合成的时间序列进行评估，结果表明生成的方案与历史序列的大多数风格化事实保持良好的一致性。

In the context of a highly uncertain global economic environment, exploring the relationship between supply chain allocation and total factor productivity (TFP) of renewable energy enterprises not only helps to optimize the support policy for renewable energy but also ensures the resilience of supply chain and promotes the micro foundation of energy transition. Based on the data of listed renewable energy enterprises in China from 2010 to 2022, this research systematically verifies the impact of the relative choice of diversification and concentration on the TFP of renewable energy enterprises from the perspective of the enterprise supply chain. The results show that: (1) Supply chain diversification can improve the TFP of renewable energy enterprises, but the impact of supply chain configuration on small and medium-sized enterprises is more significant. (2) Through mechanism analysis, it is revealed that supply chain diversification can improve the TFP of renewable energy enterprises mainly through three channels: improving the asset turnover, reducing the performance fluctuation, improving the knowledge absorptive capacity. (3) Compared with other industries, it is found that renewable energy enterprises are more vulnerable to the impact of climate change, which is the main reason for the heterogeneous impact of renewable energy supply chain configuration. Based on the above research, this study proposes policy suggestions to optimize the supply chain of renewable energy enterprises, so that renewable energy enterprises can reduce the potential fluctuation risk, by taking into account the cost reduction and efficiency increase.

在全球经济环境高度不确定的背景下，探讨供应链配置与可再生能源企业全要素生产率（TFP）之间的关系，不仅有助于优化可再生能源扶持政策，还能保证供应链的抗风险能力，促进能源转型的微观基础。本研究基于2010-2022年中国可再生能源上市企业数据，从企业供应链角度系统验证了多元化与集中化相对选择对可再生能源企业全要素生产率的影响。研究结果表明(1）供应链多元化可以提高可再生能源企业的全要素生产率，但供应链配置对中小型企业的影响更为显著。(2）通过机理分析发现，供应链多元化主要通过提高资产周转率、减少绩效波动、提高知识吸收能力三个渠道提高可再生能源企业的全要素生产率。(3）研究发现，与其他行业相比，可再生能源企业更容易受到气候变化的影响，这是造成可再生能源供应链配置异质性影响的主要原因。基于以上研究，本研究提出了优化可再生能源企业供应链的政策建议，使可再生能源企业在降低成本、提高效率的同时，降低潜在的波动风险。
