This study analyse and compare the sustainable electricity usage in 60 countries listed on the official websites of World Energy Consumption Statistics and Climate Bond Initiative. The study also analyses the impact of increased usage of sustainable electricity on the economies' dependence on non-renewable energy sources in the evaluation system. We used a standard index system based on the Pressure-State Response (PSR) model to measure global sustainable electricity usage. Model results convey that Norway is the best performer in sustainable electricity usage, while several European countries display commendable scores, confirming their commitment to sustainable electricity practices. On the other hand, despite being the leading economies in terms of GDP, major economies such as the United States, China, Japan, and India have underperformed compared to others in the evaluation system. The study employs regression techniques to explain the relationship between sustainable electricity usage and non-renewable energy dependence. Results confirm a negative relationship between the variables, indicating the role of sustainable energy practices in reducing fossil fuel consumption. It emphasizes the urgency of a balanced approach to economic growth and natural resource usage to support a green future.
本研究对世界能源消耗统计和气候债券倡议官方网站上列出的 60 个国家的可持续电力使用情况进行了分析和比较。研究还分析了可持续电力使用量的增加对评价体系中经济体对不可再生能源依赖程度的影响。我们采用了基于压力-状态响应(PSR)模型的标准指标体系来衡量全球可持续电力使用情况。模型结果表明,挪威在可持续用电方面表现最佳,而几个欧洲国家的得分也值得称赞,这证明了它们在可持续用电方面的承诺。另一方面,尽管美国、中国、日本和印度等主要经济体在国内生产总值方面处于领先地位,但在评价体系中的表现却不如其他国家。本研究采用回归技术来解释可持续用电与不可再生能源依赖性之间的关系。结果证实了变量之间的负相关关系,表明了可持续能源实践在减少化石燃料消耗方面的作用。研究强调,当务之急是平衡经济增长和自然资源使用,以支持绿色未来。

The increasing widespread utilization of renewable energy sources, especially those reliant on the weather, coupled with the effects of climate change, is making electricity markets more sensitive to weather conditions. Portugal relies heavily on hydropower for its domestic energy generation. With its robust VAR approach, this study aims to comprehend how water resource variations due to precipitation patterns or reservoir levels influence price dynamics in the wholesale electricity market. By investigating whether these price increases are associated with temperature variations and considering the impact of temperature on both electricity demand and the availability of water resources for power generation, we provide crucial insights into the vulnerability of the electricity system to hydrological uncertainties. These findings can help stakeholders, including policymakers and industry professionals, develop effective strategies to manage price fluctuations. Understanding these relationships is critical to informed decision-making regarding resource allocation, energy market regulations, and infrastructure planning to mitigate the impact of climate-induced changes on electricity prices.

可再生能源的利用越来越广泛,特别是那些依赖天气的能源,再加上气候变化的影响,使得电力市场对天气条件更加敏感。葡萄牙的国内能源生产严重依赖水力发电。本研究采用稳健的 VAR 方法,旨在了解降水模式或水库水位导致的水资源变化如何影响电力批发市场的价格动态。通过调查这些价格上涨是否与气温变化有关,并考虑气温对电力需求和用于发电的水资源可用性的影响,我们提供了电力系统易受水文不确定性影响的重要见解。这些发现可以帮助包括政策制定者和行业专业人士在内的利益相关者制定管理价格波动的有效策略。了解这些关系对于资源分配、能源市场监管和基础设施规划方面的知情决策至关重要,从而减轻气候引起的变化对电价的影响。

Energy poverty and financial literacy are two cross-cutting vital dimensions in sustainable global development. This study examines whether and how financial literacy reduces energy poverty at the household level in China. A two-way fixed regression model demonstrates the catalytic role of financial literacy in eradicating energy poverty. Furthermore, this study identifies potential mechanisms between financial literacy and energy poverty from a mediation and moderation perspective. Financial literacy indirectly and robustly mitigates energy poverty by heightening households' future expectations. However, higher financial risk weakens this facilitating effect on households’ future expectations, as increased financial risk destabilizes household finances.

能源贫困和金融扫盲是全球可持续发展中两个贯穿各领域的重要方面。本研究探讨了金融知识是否以及如何减少中国家庭层面的能源贫困。双向固定回归模型证明了金融知识在消除能源贫困中的促进作用。此外,本研究还从中介和调节的角度确定了金融知识普及与能源贫困之间的潜在机制。金融扫盲通过提高家庭对未来的预期,间接、稳健地缓解了能源贫困。然而,较高的金融风险会削弱这种对家庭未来预期的促进作用,因为金融风险的增加会破坏家庭财务的稳定性。

Water utilities face the challenge of transitioning to a low-carbon urban water cycle while reducing operational costs. This study evaluates the static and dynamic carbon efficiency of a sample of water companies from 2013 to 2018 operating in England and Wales. Each company was evaluated relative to itself and its peers using cross-efficiency Data Envelopment Analysis techniques. The results showed that the carbon performance of the water industry improved by 2.1% per year, mainly due to efficiency change. In contrast, the contribution of factors driving technical and scale change was almost negligible.

水务公司面临着向低碳城市水循环过渡,同时降低运营成本的挑战。本研究评估了 2013 年至 2018 年在英格兰和威尔士运营的水务公司样本的静态和动态碳效率。采用交叉效率数据包络分析技术,对每家公司自身及其同行进行了评估。结果显示,水务行业的碳绩效每年提高 2.1%,这主要归功于效率变化。相比之下,技术和规模变化因素的贡献几乎可以忽略不计。

Frequency Containment Reserve (FCR) Cooperation is a European effort to integrate several countries in an integrated international electricity market platform for FCR procurement. In this market, Balancing Service Providers (BSPs) are on the supply side and Transmission System Operators (TSOs) on the demand side. This paper proposes a novel settlement scheme for sharing costs among TSOs; it proposes no changes to existing market clearing rules or to the existing settlement of the BSPs’ revenues. It is shown that the current TSO settlement scheme is an inequitable mechanism that originates negative costs for some TSOs in specific conditions, which are extensively discussed. The proposed TSO settlement scheme overcomes these inequities. In the proposed scheme, TSOs begin paying the local BSPs for the cleared bids needed locally, and the remaining imports are calculated in a subsequent step. Doing so avoids using the so-called “import/export costs”, which are demonstrated to be the source of the inequities in the current scheme. It is shown that if the proposed pricing scheme had been adopted from July 2019 to December 2022, all TSOs would have been affected. Specifically, the most negatively impacted TSO would have its accumulated costs increased by 16% and the most positively impacted TSO would have its accumulated cost decreased by 32%. The inequities of the current mechanism amount to more than 50 M€ or 7.4% of the total accumulated costs. Although the proposed mechanism is tested here under the FCR Cooperation, it can be applied to other markets where the rules allow different local settlement prices.

频率控制储备(FCR)合作是欧洲的一项努力,旨在将多个国家纳入一个一体化的国际电力市场平台,以采购频率控制储备。在这个市场中,平衡服务提供商(BSP)是供应方,输电系统运营商(TSO)是需求方。本文提出了一种在 TSO 之间分担成本的新型结算方案;该方案不改变现有的市场结算规则,也不改变现有的 BSP 收入结算方式。研究表明,现行的 TSO 结算方案是一种不公平的机制,在特定条件下会给某些 TSO 带来负成本,本文对此进行了广泛讨论。拟议的 TSO 结算方案克服了这些不公平现象。在建议的方案中,TSO 开始向本地 BSP 支付本地所需的已结算投标,剩余的进口则在随后的步骤中计算。这样做可以避免使用所谓的 "进口/出口成本",而这正是现行方案中不公平的根源所在。结果表明,如果在 2019 年 7 月至 2022 年 12 月期间采用建议的定价方案,所有 TSO 都会受到影响。具体而言,受负面影响最大的 TSO 的累计成本将增加 16%,受正面影响最大的 TSO 的累计成本将减少 32%。现行机制的不公平之处超过 5000 万欧元,占累计成本总额的 7.4%。虽然建议的机制是在 FCR 合作下进行测试的,但它也可应用于规则允许不同本地结算价格的其他市场。

This study evaluates the economic value and supports infrastructure development of constructing a circular network to improve natural gas supply stability. This study applies a double-bounded dichotomous choice model and shows that households and commercial users are willing to pay an additional 2.97% and 1.19% of their monthly gas bill, respectively. This study also shows the impact of gas supply understanding and population density on willingness to pay (WTP) for both sectors. Scenario analysis is conducted to analyze the cost-benefit ratio for a hypothetical region, which may be useful in setting up new business plans.

Nigeria's 2009 environmental regulatory policy began to restrict illegal household trash disposal, introducing trash bins in many, but far from all, areas. This paper uses national household-level data to estimate the immediate effects of the national policy and geographically heterogeneous facility improvement. The largest increase in the share of households opting for sustainable disposal occurred in “emerging areas” that historically lacked trash bins but began to introduce them under the new policy. In areas without facility improvement but were otherwise comparable to emerging areas, the policy alone failed to enhance the share of households choosing the use of contained dumpsites.

尼日利亚 2009 年的环境监管政策开始限制非法的家庭垃圾处理,在许多地区(但远非所有地区)引入了垃圾箱。本文利用全国家庭层面的数据来估算国家政策和地域差异化设施改善的直接影响。在 "新兴地区",选择可持续处理方式的家庭比例增幅最大,这些地区历来没有垃圾桶,但在新政策下开始引入垃圾桶。在没有进行设施改善但在其他方面与新兴地区类似的地区,仅靠政策本身无法提高选择使用封闭式垃圾场的家庭比例。

The main aim of this paper is to determine the impact of financial inclusion on energy poverty alleviation. It also interrogates whether institutional quality and climate change risk significantly influence the financial inclusion-energy poverty alleviation link using balanced panel data from 34 Sub-Saharan African countries from 2004 to 2021. Evidence from Discroll-Kraay Fixed Effects and Two-Step Instrumental Variable Generalized Method of Moments (2SIV-GMM) depicts heterogeneous energy poverty-alleviating impact of financial inclusion, demonstrating that financial inclusion is more instrumental in lower-income than lower-middle-income countries. Also, the results indicate a significant positive moderating role of institutional quality and a detrimental effect of climate change risk on financial inclusion-energy poverty alleviation nexus. Nevertheless, Dynamic Panel Threshold Regression results reveal threshold effects of financial inclusion, institutional quality, and climate change risk on energy poverty alleviation. The paper professes that financial regulations in allocating green resources would aid in alleviating energy poverty in Sub-Saharan Africa.

本文的主要目的是确定普惠金融对能源减贫的影响。本文还利用 2004 年至 2021 年 34 个撒哈拉以南非洲国家的平衡面板数据,探讨了机构质量和气候变化风险是否会显著影响普惠金融与能源减贫之间的联系。来自 Discroll-Kraay 固定效应和两步工具变量广义矩法(2SIV-GMM)的证据描绘了普惠金融对能源减贫的异质性影响,表明普惠金融在低收入国家的作用大于中低收入国家。此外,研究结果还表明,制度质量对普惠金融-能源减贫关系具有显著的积极调节作用,而气候变化风险则具有不利影响。尽管如此,动态面板阈值回归结果显示了金融包容性、制度质量和气候变化风险对能源减贫的阈值效应。本文认为,分配绿色资源的金融法规将有助于减轻撒哈拉以南非洲的能源贫困。

The efficient management of assets delivers value and is essential for achieving service objectives, managing risks, and reducing costs. This paper proposes decision-support methods to help capital-intensive industries manage their assets and optimise their life cycle. Optimisation approaches were developed to support long-term investment planning by maximising the value created and minimising the budget used. Also, the trade-off for both objectives was analysed. Using the proposed models will lead to efficient management of available capital and excellent service delivery. Thus, water companies will fulfil the regulator’s requirements and present well-founded decision-making. This study was applied to a Portuguese water utility.

高效的资产管理能够带来价值,对于实现服务目标、管理风险和降低成本至关重要。本文提出了决策支持方法,以帮助资本密集型行业管理资产并优化其生命周期。优化方法通过最大限度地提高所创造的价值和最小化所使用的预算来支持长期投资规划。此外,还对这两个目标的权衡进行了分析。使用建议的模型可以有效管理可用资金,并提供优质服务。因此,自来水公司将满足监管机构的要求,并提出有理有据的决策。这项研究适用于葡萄牙的一家自来水公司。

Effective planning and regulatory processes ensure orderly energy systems. Often, decisions are not made within mandated timeframes and discrete approval processes are infrequent. A given delay may be compounded where multiple approval processes exist in sequence. These factors can negatively affect system costs and, ultimately, consumer welfare. We show that delays have meaningful impacts on electricity prices, system emissions, infrastructure investment and system operating costs. Our numerical simulation of data from Ireland shows that wholesale electricity prices are up to 10% higher and CO2 emissions up to 4% higher, attributable to delays associated with planning and regulatory approvals.

有效的规划和监管程序可确保能源系统有序运行。通常情况下,决策并不是在规定的时限内做出的,离散的审批程序也不常见。如果多个审批程序依次进行,则可能会加剧特定的延迟。这些因素会对系统成本产生负面影响,并最终影响消费者福利。我们的研究表明,延迟会对电价、系统排放、基础设施投资和系统运营成本产生重大影响。我们对爱尔兰的数据进行了数值模拟,结果显示,由于规划和监管审批的延误,批发电价最高会上涨 10%,二氧化碳排放量最高会增加 4%。
