The energy rebound effect threatens to realize the energy-saving effect of energy efficiency measures. The effect of the development of the digital economy on the energy rebound effect is still being determined. This paper is based on the panel data of 30 provinces in China from 2011 to 2021. A stochastic frontier model of energy demand is built to examine the influence of the digital economy on the energy rebound effect. The findings are as follows: (1) Digital economy significantly promotes the energy rebound effect. The average energy rebound impact is calculated to be 55.1%. (2) Urbanization strengthens the positive effect of the digital economy on the rebound effect. (3) Different provinces experience the rebound effect differently due to the digital economy. The digital economy has a more significant role in fostering the rebound effect in places with higher R&D intensity, lower coal share, and higher secondary sector share. This study argues that we should deepen the reform of energy prices, promote sophisticated energy-saving technology development, and promote energy structure transformation while expanding the digital economy to mitigate the negative impact of the rebound effect effectively.

能源反弹效应威胁着节能措施节能效果的实现。数字经济的发展对能源反弹效应的影响仍有待确定。本文基于 2011 年至 2021 年中国 30 个省份的面板数据。建立能源需求随机前沿模型，考察数字经济对能源反弹效应的影响。研究结果如下(1）数字经济明显促进能源反弹效应。经计算，平均能源反弹效应为 55.1%。(2）城市化加强了数字经济对能源反弹效应的积极影响。(3）不同省份因数字经济而产生的反弹效应不同。在研发强度较高、煤炭比重较低、第二产业比重较高的地方，数字经济对反弹效应的促进作用更为显著。本研究认为，在扩大数字经济规模的同时，应深化能源价格改革，推动高精尖节能技术发展，促进能源结构转型，以有效缓解反弹效应的负面影响。

Access to sustainable and reliable energy sources is a pivotal driver of economic development and improved living standards in all regions of the world. This research paper explores the policy implications of implementing residential photovoltaic (PV) solar systems in two developing regions, Jamaica, and Ghana, and emphasizes the role of policy frameworks in shaping the sustainable energy landscape. The study employs a multifaceted approach, combining System Advisor Model (SAM) analysis – which reveals promising energy production potential in both regions, with substantial economic benefits – and a risk assessment to evaluate the feasibility, economic viability, and potential barriers to residential PV solar adoption. Financial assessments indicate competitive payback periods and favorable returns on investment, suggesting that residential PV systems can offer cost-effective energy solutions. Identifying potential barriers to adoption through a comprehensive risk assessment highlights challenges related to policy instability, financing constraints, and technical limitations. Policy recommendations and strategies for mitigating these barriers are proposed to accelerate the transition to renewable energy sources in both regions. The findings underscore the potential for solar energy to address energy access challenges while advancing economic development, environmental sustainability, and energy resilience in Jamaica, and Ghana, while offering valuable lessons for similar contexts worldwide.

在世界各地，获得可持续和可靠的能源是推动经济发展和提高生活水平的关键因素。本研究论文探讨了在牙买加和加纳这两个发展中地区实施住宅光伏太阳能系统的政策影响，并强调了政策框架在塑造可持续能源景观方面的作用。该研究采用了一种多层面的方法，将系统顾问模型（SAM）分析（该模型揭示了这两个地区具有巨大经济效益的能源生产潜力）和风险评估相结合，以评估采用住宅光伏太阳能系统的可行性、经济可行性和潜在障碍。财务评估表明，投资回收期和投资回报率都很有竞争力，这表明住宅光伏系统可以提供具有成本效益的能源解决方案。通过全面的风险评估来确定采用的潜在障碍，突出了与政策不稳定性、融资限制和技术局限性有关的挑战。提出了减少这些障碍的政策建议和战略，以加快这两个地区向可再生能源的过渡。研究结果强调了太阳能在应对能源获取挑战、促进牙买加和加纳的经济发展、环境可持续性和能源恢复能力方面的潜力，同时也为全球类似情况提供了宝贵经验。

The effects of climate change are evident. Globally, there is momentum to use electric vehicles (EVs) to reduce the effects of climate change but these EVs are yet to become mainstream. Against this backdrop, the study aims to understand the behaviour of consumers to use electric vehicles. The study adopts a multi-phase qualitative research design to uncover the reasons for and reason against EVs car use. Innovation resistance theory and innovation diffusion theory are used as theoretical foundations for inquiry. The study focuses on EV cars and investigates Indian consumers. The qualitative data were collected from prospective, buyer, and non-buyers of EV car in multiple phases. The findings are presented across two broader themes of drivers and barriers. The study contributes to the theoretical advancement of EVs. It also offers implications for policymakers and manufacturers to bring EVs into the mainstream and reap their economic and ecological benefits.

气候变化的影响显而易见。在全球范围内，使用电动汽车（EV）来减少气候变化影响的势头正劲，但这些电动汽车尚未成为主流。在此背景下，本研究旨在了解消费者使用电动汽车的行为。本研究采用多阶段定性研究设计，以揭示消费者使用电动汽车的原因和反对使用电动汽车的原因。创新阻力理论和创新扩散理论被用作研究的理论基础。研究重点是电动汽车，调查对象是印度消费者。研究分多个阶段从电动汽车的潜在消费者、购买者和非购买者那里收集定性数据。研究结果分为驱动因素和障碍两大主题。这项研究有助于电动汽车理论的发展。它还为政策制定者和制造商将电动汽车引入主流并获得其经济和生态效益提供了启示。

To better integrate fluctuant renewable energy sources, we investigate the local value of decentral flexibility options e.g., battery storage systems, electric vehicles and heat pumps, under nodal market design. A novel framework to depict the economic value of decentral flexibility units at different locations is presented: First, based on an energy system model, nodal as well as zonal price time series are generated. Second, flexibility values are computed based on these price time series using operation models. Our case study for 2030 for Europe demonstrates the high value of decentral flexibility provided especially by bidirectional flexibility options. The mean daily price spread is found to be a main driver for all flexibility values. We observe similar flexibility values across most nodes in both market designs. However, for a distinct subset of nodes that represent close to 10% of total demand, substantially higher values of local flexibilities are observed which indicates a markedly higher demand for flexibility. Yet, the zonal market design only provides imperfect incentives for the system-oriented operation of flexibilities at these nodes. Besides the introduction of nodal pricing as first-best option, we propose to consider tailored instruments focusing on these flexibility hot spots as second-best policies.

为了更好地整合波动性可再生能源，我们研究了节点市场设计下分散灵活性选择（如电池存储系统、电动汽车和热泵）的本地价值。我们提出了一个新颖的框架，用于描述不同地点分散灵活性单元的经济价值：首先，基于能源系统模型，生成节点和区域价格时间序列。其次，根据这些价格时间序列，利用运行模型计算灵活性价值。我们对欧洲 2030 年的案例研究表明，分散式灵活性具有很高的价值，尤其是双向灵活性选项。我们发现，日平均价差是所有灵活性值的主要驱动因素。我们观察到，在两种市场设计中，大多数节点的灵活性值相似。然而，在占总需求近 10%的一个明显的节点子集中，我们观察到的本地灵活性值要高得多，这表明对灵活性的需求明显更高。然而，分区市场设计只是为这些节点以系统为导向的灵活性运行提供了不完善的激励。除了引入节点定价作为第一最佳方案外，我们还建议考虑针对这些灵活性热点的定制工具，作为第二最佳政策。

Corporate power purchase agreements (CPPAs) have emerged as an additional instrument for accelerating renewable energy deployment. By facilitating the financing of projects, CPPAs offer numerous benefits to power producers and corporate offtakers. However, despite their growing popularity, risk allocation among these counterparties remains challenging. This study investigates risk perceptions and preferences for CPPA design based on insights from 91 corporate offtakers who made 860 hypothetical green-power-procurement decisions in the Swiss context. Our results show a strong interest in CPPAs with lower prices and shorter tenors. The latter is especially important for SMEs, who would be willing to pay considerably more for a five-year contract than a longer one. While large companies would pay hefty premiums for local power production, SMEs impute more importance to the type of technology. However, long-term commitments and the complexity of contractual obligations are major drawbacks. While our findings show that CPPAs have the potential to play an important role in complementing public support for renewables, they also point to the need to implement framework conditions that contribute to lowering risks and complexity for counterparties. Further, they highlight distinctive preferences within this consumer segment, which could inform CPPA negotiations and foster mutually beneficial agreements.

企业购电协议（CPPA）已成为加快可再生能源部署的又一工具。通过促进项目融资，企业购电协议为电力生产商和企业承购商带来了诸多好处。然而，尽管它们越来越受欢迎，这些交易方之间的风险分配仍然具有挑战性。在瑞士，91 家企业承购方做出了 860 项假设的绿色电力采购决策，本研究根据这些企业承购方的意见，调查了他们对 CPPA 设计的风险认知和偏好。我们的研究结果表明，企业对价格较低、期限较短的 CPPA 非常感兴趣。后者对中小型企业尤为重要，因为与较长的合同相比，中小型企业愿意为五年期合同支付更多的费用。大公司愿意为本地发电支付高额溢价，而中小企业则更看重技术类型。然而，长期承诺和合同义务的复杂性是主要缺点。虽然我们的研究结果表明，《清洁生产者协议》有可能在补充可再生能源的公共支持方面发挥重要作用，但同时也指出，有必要实施有助于降低交易方风险和复杂性的框架条件。此外，我们还强调了这一消费群体的独特偏好，这可以为 CPPA 谈判提供参考，并促进互利协议的达成。

Appropriate consumer subsidies can effectively address energy poverty. However, in China, the continued high level of fossil energy consumer subsidies, influenced by the energy consumption structure, may impede the green, low-carbon, and high-quality development of energy production companies. This study examines coal mines in Shandong province from 2017 to 2021 to explore the effects of consumer subsidies on mine production efficiency and its mechanisms. The results show that technological advancements are essential for mine production efficiency improvement, but consumer subsidies have a significant negative effect on mine production efficiency, and the influence weight is −0.020. Additionally, the mechanism analysis reveals that consumer subsidies affect mine production efficiency through factors such as environmental governance, market competition, and management quality. It is proposed that reforms in the coal market, including optimizing the long-term cooperative pricing mechanism, could mitigate the negative effects of consumer subsidies and support energy structure adjustments.

适当的消费补贴可以有效解决能源贫困问题。然而，在中国，受能源消费结构的影响，化石能源消费补贴水平居高不下，可能会阻碍能源生产企业的绿色、低碳、高质量发展。本研究以山东省 2017 年至 2021 年煤矿为研究对象，探讨消费补贴对煤矿生产效率的影响及其机制。结果表明，技术进步对煤矿生产效率提升至关重要，但消费补贴对煤矿生产效率有显著负向影响，影响权重为-0.020。此外，机理分析表明，消费补贴通过环境治理、市场竞争和管理质量等因素影响煤矿生产效率。建议通过煤炭市场改革，包括优化长期合作定价机制，缓解消费补贴的负面影响，支持能源结构调整。

This paper systematically analyzes the effect of energy efficiency on transacted rental and capital values of Dutch retail property assets from 2015–2021. Prior research on Energy Performance Certification (EPC) and energy premiums consistently showed a pricing effect, but recent investigations reveal inconclusive results, particularly when considering non-residential properties. Leveraging a unique dataset of 1015 lease transactions and 478 sale transactions, this study provides one of the first estimates of how EPC labels impact retail value. We utilize ordinary least squares (OLS) regression, considering characteristic retail determinants such as footfall, catchment area type, and retail type, among others. This study finds a premium of 11 percent for rental transactions with Label C or higher on a price per square meter basis. Capital premiums for energy-efficient transactions are more marginal and complex, particularly when accounting for data limitations such as geographic distribution. The nexus between sustainability and financial benefits incentivizes investors and policymakers to embrace energy-efficient measures. Pioneering spatial analyses of EPCs in the retail sector, this paper offers insights for informed policy-making amid geographic variations. In the era of transparency, this research provides empirical evidence to drive responsible investments in energy-efficient retail, shifting from risk management to stakeholder benefits and improved capital efficiency.

本文系统分析了 2015-2021 年间能源效率对荷兰零售物业资产交易租金和资本价值的影响。之前关于能源性能认证（EPC）和能源溢价的研究一直显示出定价效应，但最近的调查却显示出不确定的结果，尤其是在考虑非住宅物业时。本研究利用包含 1015 项租赁交易和 478 项销售交易的独特数据集，首次估算了 EPC 标签对零售价值的影响。我们利用普通最小二乘法（OLS）回归，考虑了人流量、集聚区类型和零售类型等零售特征决定因素。研究发现，按每平方米价格计算，标签 C 或更高的租赁交易溢价 11%。高能效交易的资本溢价更为微小和复杂，特别是在考虑到地理分布等数据限制的情况下。可持续发展与经济效益之间的联系激励投资者和政策制定者采用节能措施。本文开创性地对零售行业的 EPC 进行了空间分析，为在地域差异中做出明智决策提供了启示。在透明时代，这项研究提供了经验证据，以推动对节能零售业进行负责任的投资，从风险管理转向利益相关者的利益和资本效率的提高。

Recently, the uptake of renewable energy has surged in distribution networks, particularly due to the cost-effectiveness and modular nature of photovoltaic systems. This has paved the way to a new era of user engagement, embodied by individual and collective self-consumption, and promoted by the EU Directive 2018/2001, which advocates for the establishment of Renewable Energy Communities. However, the transposition of this directive varies across Member States, resulting in specific rules for each country. In this work, the impact that different energy sharing models have on the same community is quantitatively assessed. The policy analysis focuses on the regulation of two countries, Italy and Portugal, chosen for the specular ways in which their models operate, respectively virtually and physically. The analysis is supported by a suite of tools which includes two optimization problems for community's operations, one for each analysed regulation, and a set of consumer protection mechanisms, to ensure no member is losing money while in community. Results demonstrate that the sharing model impacts community's optimal operations, optimal battery size and configuration, and members' benefit. As these models are sensitive to different variables, personalized interventions at national level are required.

最近，可再生能源在配电网络中的使用量激增，这主要归功于光伏系统的成本效益和模块化特性。这为用户参与的新时代铺平了道路，体现为个人和集体的自我消费，欧盟第 2018/2001 号指令倡导建立可再生能源社区。然而，各成员国对该指令的执行情况不尽相同，导致每个国家都有自己的具体规则。在这项工作中，对不同能源共享模式对同一社区的影响进行了量化评估。政策分析的重点是意大利和葡萄牙这两个国家的法规，选择这两个国家是因为它们的模式分别以虚拟和物理的方式运行。分析得到了一套工具的支持，其中包括两个社区运营优化问题（每个被分析的法规都有一个优化问题）和一套消费者保护机制，以确保没有成员在社区中遭受损失。结果表明，共享模式会影响社区的最佳运营、最佳电池大小和配置以及成员的利益。由于这些模式对不同变量很敏感，因此需要在国家层面进行个性化干预。

The analysis is supported by a suite of tools which includes two optimization problems for community's operations, one for each analysed regulation, and a set of consumer protection mechanisms, to ensure no member is losing money while in community. Results demonstrate that the sharing model impacts community's optimal operations, optimal battery size and configuration, and members' benefit. As these models are sensitive to different variables, personalized interventions at national level are required.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"195 ","pages":"Article 114399"},"PeriodicalIF":9.3,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper addresses the knowledge gap concerning foreign exchange risk in energy transactions within the Regional Initiative Energy Integration System of the Southern Cone Countries (SIESUR) of the Latin American region. Focusing on the cross-border electricity, it investigates the impact of exchange rate fluctuations on the transaction model in SIESUR: US dollar-denominated cross-border energy contracts with a time lag between invoicing and payment. The objective of this paper is to estimate foreign exchange risk exposure and propose mitigation solutions. Analyzing foreign exchange risk of energy trading among SIESUR member countries reveals substantial financial costs hindering electricity integration. Energy importing countries, facing greater exposure of their local currencies and weakened bargaining power, are particularly vulnerable. A Monte Carlo simulation model, using historical exchange rate data, highlights significant currency volatility, emphasizing the substantial foreign exchange risk exposure within SIESUR. Notably, cost overruns of energy imports due to foreign exchange risk exposure can reach 12.6% of transaction value. Through a global analysis, potential strategies for risk management are explored to foster electricity exchange expansion. Efforts to mitigate foreign exchange risk are crucial for advancing electricity integration within the SIESUR region. This study underscores policy implications for enhancing regional energy security and promoting sustainable development.

本文探讨了拉丁美洲南锥体国家能源一体化区域倡议系统（SIESUR）内能源交易外汇风险方面的知识空白。本文以跨境电力为重点，研究了汇率波动对 SIESUR 交易模式的影响：以美元计价的跨境能源合同，发票开具和付款之间存在时间差。本文旨在估算外汇风险敞口，并提出缓解方案。通过分析南方市场成员国之间能源贸易的外汇风险，可以发现阻碍电力一体化的巨大金融成本。能源进口国的本币风险更大，议价能力更弱，因此尤其容易受到影响。利用历史汇率数据建立的蒙特卡罗模拟模型显示，货币的波动性很大，这凸显了南锥体共同市场内部面临的巨大外汇风险。值得注意的是，外汇风险导致的能源进口成本超支可达到交易额的 12.6%。通过全球分析，探讨了潜在的风险管理战略，以促进电力交换的扩展。努力降低外汇风险对于推进南方共同市场地区内的电力一体化至关重要。本研究强调了加强地区能源安全和促进可持续发展的政策影响。
