In the context of the “dual carbon” strategy, how to leverage green finance to promote China's wind power industry is a hot topic. Unlike existing literature, this article uses a nonparametric additive model to investigate the impact and mechanism of green finance on wind power development. Research has found that green finance has an inverted U-shaped nonlinear impact on wind power development, indicating that green finance has a more prominent contribution to the wind power industry in the early stages. Further mechanism research indicates that green finance affects the wind power industry through foreign direct investment and green technology innovation. Specifically, with the relaxation of foreign direct investment conditions in the energy sector, the role of foreign direct investment in promoting the wind power industry more prominent in the later stages. In the early stages, government support was greater, and green technology patents grew rapidly, driving green technology innovation to have a more significant impact on the wind power industry. In addition, the impact of fiscal decentralization, wind power prices, and environmental regulations on the wind power industry also exhibits significant nonlinear characteristics. This article helps to comprehensively understand the mechanism and impact of green finance on wind power development, and provides a reliable basis for optimizing green finance policy and effectively promoting wind power.
在 "双碳 "战略背景下,如何利用绿色金融促进中国风电产业发展是一个热门话题。与现有文献不同,本文采用非参数加法模型研究绿色金融对风电发展的影响和机制。研究发现,绿色金融对风电发展具有倒 U 型的非线性影响,表明绿色金融在早期阶段对风电产业的贡献更为突出。进一步的机制研究表明,绿色金融通过外商直接投资和绿色技术创新对风电产业产生影响。具体而言,随着能源领域外商直接投资条件的放宽,外商直接投资对风电产业的促进作用在后期更为突出。而在早期阶段,政府支持力度较大,绿色技术专利增长迅速,推动绿色技术创新对风电产业的影响更为显著。此外,财政分权、风电价格和环保法规对风电产业的影响也呈现出显著的非线性特征。本文有助于全面了解绿色金融对风电发展的作用机制和影响,为优化绿色金融政策、有效促进风电发展提供可靠依据。

Life prediction significantly influences the reliability of LED light sources. While high-power LED light sources theoretically offer a lifespan of up to 100,000 h, irreversible damage to components leads to light failure, substantially reducing their actual lifespan. Consequently, accurate life prediction is pivotal for manufacturers to cut costs and enhance economic efficiency. This necessity aligns with the interests of communities, governments, and consumers. Currently, the most extensively employed prediction methods are based on traditional physical models and data-driven approaches. The focal point of current research lies in realizing model fusion, presenting both a hotspot and a challenge. To elucidate the relationships, advantages, and disadvantages of different algorithms and establish the groundwork for LED life prediction algorithm development, this paper first introduces material properties and the light decay model of high-power LED light sources. Subsequently, it discusses the principles and methods of the physical model concerning light source reliability. The paper also presents a review and comparison of recent domestic and foreign light source life prediction models. Finally, it provides insights into the expected future development trends in life prediction.
寿命预测在很大程度上影响着 LED 光源的可靠性。虽然大功率 LED 光源理论上可提供长达 100,000 小时的使用寿命,但元件不可逆转的损坏会导致光衰,从而大大缩短实际使用寿命。因此,准确的寿命预测对制造商降低成本和提高经济效益至关重要。这种必要性符合社区、政府和消费者的利益。目前,最广泛使用的预测方法是基于传统物理模型和数据驱动的方法。当前研究的重点在于实现模型融合,这既是热点也是难点。为了阐明不同算法之间的关系和优缺点,为 LED 寿命预测算法的开发奠定基础,本文首先介绍了大功率 LED 光源的材料特性和光衰模型。随后,本文讨论了与光源可靠性有关的物理模型的原理和方法。本文还对近期国内外光源寿命预测模型进行了回顾和比较。最后,对寿命预测的未来发展趋势进行了展望。

Household decisions to adopt rooftop solar photovoltaics are partly driven by social influence. Previous research on solar adoption influence has focused on influence among residential peers. Here, we expand the framework of solar adoption influence by exploring the influence of non-residential installations on residential adoption decisions. We use staggered differences-in-differences to estimate non-residential influence effects using a large data sample of residential adoptions. We also critically evaluate prevailing frameworks for solar adoption influence. We find that non-residential installations are associated with accelerated residential adoption rates, on the order of 0.4 additional residential adoptions per quarter per non-residential installation. We show that non-residential systems exert a continuous, long-term influence on residential adoption decisions. We explore separate results and influence mechanisms for solar installed on commercial buildings, government buildings, and houses of worship. The results suggest that non-residential solar adopters could serve as partners in policies to “seed” residential adoption in underserved communities.
家庭采用屋顶太阳能光伏发电技术的决定部分受社会影响的驱动。以往关于太阳能应用影响的研究主要集中在住宅同行之间的影响。在这里,我们通过探讨非住宅安装对住宅采用太阳能决策的影响,扩展了太阳能采用影响的框架。我们采用交错差分法,利用大量住宅采用情况的数据样本来估算非住宅影响效应。我们还对太阳能应用影响的现有框架进行了批判性评估。我们发现,非住宅系统的安装与住宅系统采用率的加快有关,每安装一个非住宅系统,住宅系统采用率每季度就会增加 0.4 个。我们表明,非住宅系统对住宅采用太阳能的决策具有持续、长期的影响。我们对安装在商业建筑、政府建筑和宗教建筑上的太阳能系统的不同结果和影响机制进行了探讨。结果表明,非住宅太阳能采用者可以作为政策的合作伙伴,在服务不足的社区 "播下 "住宅采用太阳能的种子。

Academic literature on energy justice sits at the intersection of a complex ecosystem of technologies, geographies, disciplinary traditions, terminologies, frameworks, theories, and methods. Its recent and rapid growth suggests it is of interest to a large number of stakeholders. However, these same features make aggregation and summarization a considerable undertaking.This article uses advanced bibliometric analytics to synthesize this disparate and varied metadata to characterize trends in the treatment of energy justice in academic literature. The review covers 4,196 articles published between 1983 and 2023 with methods appropriate to the number and diversity of publications and associated subfields.We document distinct uses of similar terminologies across subfields in literature, inequitable ratios of global research compared to absolute levels of energy poverty, and the large but under-recognized contribution of cooking to the energy justice literature.In summarizing this voluminous literature and analyzing thematic changes over time, we provide scaffolding for more detailed reviews to place themselves within the larger interconnected literature network.
关于能源正义的学术文献处于技术、地理、学科传统、术语、框架、理论和方法等复杂生态系统的交叉点。它最近的快速增长表明,许多利益相关者都对它感兴趣。然而,这些相同的特性使得聚合和总结成为一项相当艰巨的任务。本文使用先进的文献计量学分析来综合这些不同的和不同的元数据,以表征学术文献中处理能源正义的趋势。该综述涵盖了1983年至2023年间发表的4196篇文章,采用的方法适合于出版物和相关子领域的数量和多样性。我们记录了文献中不同子领域对类似术语的不同使用,与能源贫困的绝对水平相比,全球研究的不公平比例,以及烹饪对能源正义文献的巨大但未被充分认识的贡献。在总结这些大量的文献和分析随时间的主题变化时,我们为更详细的评论提供了框架,以便将自己置于更大的相互关联的文献网络中。

Energy insecurity poses a global challenge with far-reaching social equity and health implications. This paper provides a comprehensive perspective on the relationship between energy insecurity and health outcomes in developed countries. Existing research has identified associations between energy insecurity and various physical and mental health outcomes. Moreover, climate change can exacerbate the adverse health consequences of energy insecurity, disproportionately affecting vulnerable populations. Based on a review of existing literature, this paper identifies several knowledge gaps, proposes future research directions, and discusses data challenges faced by researchers in measuring energy insecurity and assessing the health impacts of existing programs that tackle energy insecurity. Furthermore, the paper highlights the importance of fostering collaboration among different governmental agencies and other sectors to enhance energy insecurity program management and data collection for program evaluation.
能源不安全是一项全球性挑战,具有深远的社会公平和健康影响。本文对发达国家能源不安全与健康结果之间的关系提供了一个全面的视角。现有的研究已经确定了能源不安全与各种身心健康结果之间的联系。此外,气候变化可能加剧能源不安全对健康造成的不利后果,对弱势群体造成不成比例的影响。在回顾现有文献的基础上,本文确定了几个知识缺口,提出了未来的研究方向,并讨论了研究人员在测量能源不安全和评估现有能源不安全项目对健康影响方面面临的数据挑战。此外,本文强调了促进不同政府机构和其他部门之间合作的重要性,以加强能源不安全项目管理和项目评估数据收集。

Numerous recent calls have been made for policy design research to embed itself throughout the policy process and explore avenues for matching tools and targets. These calls have argued that policy design research, while emphasizing the content and the choice of design, has been under-leveraged, particularly in exploring rationales for effectiveness. In this paper, we conduct a comparative case study to explore variation in participation rates for two similarly categorized solar policies across two mid-sized cities. In this regard, three contextual factors are examined, including the population characteristics, the existing configuration of policies, and the physical environment, which all contribute to shaping policy effectiveness. We argue that policy design is situated within an explicit context and that without capturing the context, the effectiveness of policies may not translate if diffused.
最近有许多人呼吁将政策设计研究嵌入到整个政策过程中,并探索匹配工具和目标的途径。这些呼吁认为,政策设计研究虽然强调设计的内容和选择,但杠杆作用不足,特别是在探索有效性的基本原理方面。在本文中,我们进行了一个比较案例研究,以探讨两个中等城市中两种类似分类的太阳能政策的参与率变化。在这方面,研究了三个背景因素,包括人口特征、现有政策结构和自然环境,它们都有助于形成政策的有效性。我们认为,政策设计是在一个明确的背景下进行的,如果没有捕捉到背景,政策的有效性可能不会在扩散的情况下转化。

The target of universal access to affordable, reliable, and modern energy services—key for individual, social, and economic well-being—is unlikely to be achieved by 2030 based on the current trend. Public policy will likely need to play a key role in accelerating progress in this regard. Although perspectives from the field of policy studies can support this effort, to what extent they have been employed in the literature on energy access remains unclear.This study analyzed nearly 7,500 publications on energy access through a combination of bibliometric review and computational text analysis of their titles and abstracts to examine whether and how they have engaged with public policy perspectives, specifically, policy process research, policy design studies, and the literature on policy evaluation.We discovered 27 themes in the literature on energy access, but public policy was not among them. Subsequently, we identified 23 themes in a new analysis of the 1,751 publications in our original dataset, mentioning “policy” in their title or abstract. However, few of them engaged with public policy, and even those that did comprised a rather small share of the literature. Finally, we extracted phrases pertaining to public policy in this reduced dataset, but found limited mention of terms related to the policy process, policy design, or policy evaluation.While to some extent this might reflect the multidisciplinary nature of the research on energy access, a manual review of the abstracts of select publications corroborated this finding. Also, it shed light on how the literature has engaged with public policy and helped identify opportunities for broadening and deepening policy relevant research on energy access. We conclude that, despite their relevance to energy access, public policy perspectives have infrequently and unevenly informed existing research on the topic, and call on scholars in both communities to address this gap in the future.
普遍获得负担得起的、可靠的、现代的能源服务——这是个人、社会和经济福祉的关键——的目标,根据目前的趋势,到2030年不太可能实现。公共政策可能需要在加速这方面的进展方面发挥关键作用。尽管政策研究领域的观点可以支持这一努力,但它们在能源获取文献中的应用程度尚不清楚。本研究通过文献计量回顾和对标题和摘要的计算文本分析相结合,分析了近7500份关于能源获取的出版物,以检查它们是否以及如何参与公共政策视角,特别是政策过程研究、政策设计研究和政策评估文献。我们在有关能源获取的文献中发现了27个主题,但公共政策并不在其中。随后,我们对原始数据集中的1751份出版物进行了新的分析,确定了23个主题,在标题或摘要中提到了“政策”。然而,他们中很少有人涉及公共政策,即使是那些涉及公共政策的人,也只占文学作品的一小部分。最后,我们在这个简化的数据集中提取了与公共政策相关的短语,但发现与政策过程、政策设计或政策评估相关的术语提及有限。虽然这在某种程度上可能反映了能源获取研究的多学科性质,但对选定出版物摘要的人工审查证实了这一发现。此外,它还揭示了文献如何与公共政策相结合,并帮助确定了扩大和深化与能源获取相关的政策研究的机会。我们的结论是,尽管公共政策观点与能源获取相关,但它们对该主题的现有研究的影响很少且不均衡,并呼吁两个社区的学者在未来解决这一差距。

Electricity price modeling from the perspective of start-up costs: incorporating renewable resources in non-convex markets 启动成本视角下的电价建模:在非凸市场中纳入可再生资源

This paper constructs a comprehensive electricity market model in the context of China, highlighting the deviation caused by neglecting start-up costs from an engineering perspective. The model allows for the abandonment of excess wind and solar power generation, contributing to the achievement of research objectives in scenarios with a high proportion of renewable energy. Our method innovatively integrates fuel and carbon prices, clean energy expansion, and power system marginal prices according to the carbon trading rules of the Chinese power industry, providing a more accurate representation of market dynamics. Findings reveal that neglecting start-up costs can lead to significant biases in electricity prices. We demonstrate that the marginal price sometimes deviates from the fluctuation of the real value. While fuel and CO2 prices can be transmitted downstream, the value of new energy must be transmitted through its impact on the marginal unit. This insight is crucial for understanding the “missing money” problem in electricity markets. Based on these findings, we propose policy recommendations. We suggest considering fixed and average costs as pricing benchmarks and utilizing capacity utilization as a signal for demand response to adjust power pricing. Furthermore, we recommend trading different energy types separately in the spot market with different pricing benchmarks to ensure the homogeneity of marginal units.
本文以中国为背景构建了一个全面的电力市场模型,从工程角度突出了由于忽略启动成本而产生的偏差。该模型允许放弃多余的风能和太阳能发电,有助于在可再生能源比例较高的情况下实现研究目标。我们的方法创新地将燃料和碳价格、清洁能源扩张和电力系统边际价格结合起来,根据中国电力行业的碳交易规则,更准确地反映了市场动态。研究结果表明,忽略启动成本会导致电价的显著偏差。我们证明了边际价格有时会偏离实际价值的波动。虽然燃料和二氧化碳的价格可以向下传递,但新能源的价值必须通过其对边际单位的影响来传递。这种见解对于理解电力市场的“缺钱”问题至关重要。基于这些发现,我们提出了政策建议。我们建议考虑固定成本和平均成本作为定价基准,并利用产能利用率作为需求响应的信号来调整电价。此外,我们建议在现货市场上对不同能源类型进行单独交易,并采用不同的定价基准,以确保边际单位的同质性。

The model allows for the abandonment of excess wind and solar power generation, contributing to the achievement of research objectives in scenarios with a high proportion of renewable energy. Our method innovatively integrates fuel and carbon prices, clean energy expansion, and power system marginal prices according to the carbon trading rules of the Chinese power industry, providing a more accurate representation of market dynamics. Findings reveal that neglecting start-up costs can lead to significant biases in electricity prices. We demonstrate that the marginal price sometimes deviates from the fluctuation of the real value. While fuel and CO2 prices can be transmitted downstream, the value of new energy must be transmitted through its impact on the marginal unit. This insight is crucial for understanding the “missing money” problem in electricity markets. Based on these findings, we propose policy recommendations. We suggest considering fixed and average costs as pricing benchmarks and utilizing capacity utilization as a signal for demand response to adjust power pricing. Furthermore, we recommend trading different energy types separately in the spot market with different pricing benchmarks to ensure the homogeneity of marginal units.","PeriodicalId":262866,"journal":{"name":"Frontiers in Sustainable Energy Policy","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130221750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global Sustainable Development Goals require meeting multiple objectives on energy, population, economics, and ecosystems. Development and economic growth as defined by current metrics requires energy inputs, yet energy growth can also increase negative impacts on natural systems. To achieve sustainable development goals, policymakers and technologists will need energy system solutions that consider not only cost and efficiency but also population, quality of life, natural ecosystems, and culture that accommodates different starting points and transition timelines of various countries. To explore possible approaches, this perspectives paper summarizes energy in the context of economic growth and population, illustrating concepts through the diverse status and direction of three countries—Japan, the United States, and Bangladesh—as potential views into a post-growth sustainable future. Four fundamental questions on long-term energy development are identified, related to optimal energy use per capita, sustainable global energy demand, managing an energy transition with stable population, and the need for generalizable approaches across countries.
全球可持续发展目标要求实现能源、人口、经济和生态系统等多个目标。当前指标所定义的发展和经济增长需要能源投入,但能源增长也会增加对自然系统的负面影响。为了实现可持续发展目标,政策制定者和技术人员将需要能源系统解决方案,不仅要考虑成本和效率,还要考虑人口、生活质量、自然生态系统和文化,以适应不同国家的不同起点和过渡时间表。为了探索可能的方法,本文总结了经济增长和人口背景下的能源问题,并通过日本、美国和孟加拉国这三个国家不同的地位和发展方向阐述了能源概念,作为对增长后可持续未来的潜在看法。确定了关于长期能源发展的四个基本问题,涉及人均最佳能源使用、可持续的全球能源需求、在人口稳定的情况下管理能源转型,以及需要在各国采用可推广的办法。

Impacts on manufacturing workers as part of a whole-system energy transition 作为整个系统能源转型的一部分,对制造业工人的影响

Providing access to good employment opportunities has become a key area of focus to ensure a just energy transition and to ensure that there is sufficient support for the technology transitions necessary for deep decarbonization. However, a societal transition to a decarbonized energy system will impact workers beyond those involved in energy resource extraction and energy production. Workers involved in manufacturing, especially those working in manufacturing industries that are energy- and emissions-intensive may face additional changes as those industries undergo technological changes. While discussions of the quality of jobs have focused on things like compensation, employment terms, and representation, other job dimensions, like the intrinsic characteristics of the work, health and safety, and work–life balance, stand to be directly impacted by technology change and are largely excluded from consideration. As these new technologies are developed and new energy sources are introduced to support manufacturing, we should also consider sociotechnical solutions that balance worker quality of life among other considerations like the utilization of new capital resources. Incorporating considerations across a wider definition of job quality dimensions will help to ensure that there is a sufficient workforce available to meet the demands of a decarbonization transition.
提供获得良好就业机会的机会已成为确保公正的能源转型和确保对深度脱碳所必需的技术转型提供足够支持的关键重点领域。然而,向脱碳能源系统的社会转型将影响到能源开采和能源生产以外的工人。从事制造业的工人,特别是那些在能源和排放密集型制造业工作的工人,可能会面临更多的变化,因为这些行业正在经历技术变革。虽然关于工作质量的讨论主要集中在薪酬、雇佣条款和代表性等方面,但其他工作方面,如工作的内在特征、健康和安全以及工作与生活的平衡,会受到技术变革的直接影响,在很大程度上被排除在考虑之外。随着这些新技术的发展和新能源的引入来支持制造业,我们还应该考虑社会技术解决方案,在新资本资源的利用等其他考虑因素中平衡工人的生活质量。在更广泛的工作质量维度定义中纳入考虑因素将有助于确保有足够的劳动力来满足脱碳转型的需求。
