This paper critically examines the legal definition of waste heat and the provisions on waste heat in the European Union's Renewable Energy Directive (RED III). The legal definition is crucial for aligning waste heat with the overarching energy efficiency and renewable energy objectives and has direct implications for the efficient use of energy and national policies. The legal analysis identifies ambiguities and inconsistencies that may result in uncertainty and the non-implementation of waste heat measures. The paper concludes with recommendations to improve the clarity and derive practical applicability of the aforementioned provisions.

This study examines the relationship between energy poverty and personal time allocation using China Family Panel Studies (CFPS) data. We found that household energy poverty significantly reduces work and leisure time but increases housework time. Potential mechanisms include health status, employment type, and single status. Our results show that energy poverty reduces effective time utilization, wasting human resources and potentially hindering socio-economic development. We recommend that China's government recognize and alleviate the negative impact of household energy poverty to support socio-economic development, providing an empirical reference for other developing countries.

Common risk factors for Latin American electric utilities

Investment in electric power infrastructure is needed to ensure access to affordable, secure, and sustainable energy in Latin America by 2030. A determining factor to stimulate this type of investment is the rate of return approved by the regulatory commissions. The return expected by investors (cost of equity) depends on the risks associated with these investments. Regulatory commissions commonly use the Capital Asset Pricing Model (CAPM), for which only market risk is relevant. Market risk is low for regulated firms, ignoring other risk types, and is measured with firms and variables outside the Latin American region. This procedure, however, does not consider the risks these types of investments are exposed to in Latin America. In this analysis, six risk factors were initially proposed to explain the risk-return relationship of these types of investments; nevertheless, after an exploratory analysis of the factors, two factors were eliminated to form a four-factor model (Electric-4). Then, the CAPM model was contrasted with the Electric-4 model. Both models used Latin American firms and market variables, and both were evaluated between July 2010 and July 2022. The analysis sample comprises 28 electric utilities dedicated to transmission and distribution. Through regression analysis, we found that the Electric-4 model explains a higher percentage of the variations in the portfolio returns of electric utilities in the Latin American Integrated Market (MILA), São Paulo Stock Exchange (BM&F), and Buenos Aires Stock Exchange (BCBA). These results help to understand the risk-return relationship of electric power infrastructure investments in the Americas for investment decision-making. In addition, the proposed model aids the regulatory commissions in Latin America in establishing an adequate return on equity cost of capital that encourages investments in electric power infrastructure.

Governments worldwide are pursuing public policies to reduce greenhouse gas emissions while sustaining economic growth. Several methodologies, including the Logarithmic Mean Divisia Index (LMDI) decomposition, Tapio decoupling analysis, and the decoupling effort method, have been employed to analyze energy-related carbon dioxide emissions. These approaches have been applied across various time frames: single-period, year-by-year, and multi-period analyses. However, previous studies have often overlooked significant trend changes in the indicators. This study introduces a methodology that integrates decomposition and decoupling analysis within a multi-period time frame, explicitly accounting for major trend shifts in the carbon dioxide time series. The time frame is defined using a total mean squared error (TMSE) minimization approach. The decomposition analysis employs the additive LMDI method, while the decoupling analysis utilizes the Tapio and decoupling effort models. A case study of Portugal’s carbon dioxide emissions from 1995 to 2020, disaggregated into six energy-consuming sectors, demonstrates the effectiveness of this methodology. The results highlight the substantial impact of carbon intensity, particularly in the electricity and heat sectors. This study demonstrates that accounting for trend changes in period selection provides critical insights, enabling a more thorough and accurate analysis of carbon dioxide emissions.

This paper analyzes Nigeria's rural-urban inequality in drinking water accessibility. The paper shows that rural-urban inequality could largely be attributed to wealth status. Within each wealth group, the degree of rural-urban inequality was statistically insignificant. These findings suggest that Nigeria's issues of drinking water inaccessibility were primarily a socioeconomic challenge rather than rural-urban disparities in infrastructure and services beyond individual households. The observed inequality largely stemmed from the concentration of households with low socioeconomic status in rural Nigeria, but low-income urban residents experienced a comparable degree of water inaccessibility and derived no inherent benefit from urban residency.

The increasing pressure on corporations from their stakeholders regarding sustainability is a pivotal driver of transparency on environmental, social, and governance (ESG) topics. New policy directions and ongoing global socio-political dynamics guide the attention. In this context, the utilities sector presents fertile soil for exploring how ESG accountability shapes corporate practices. In this editorial, we discuss ESG reporting as a topic of analysis and describe the primary trends in the literature that support its development. The studies published in this Special Issue are also presented to the reader. Finally, we describe the emerging paths for research on ESG reporting in the sector, focusing on providing policymakers insights. What we learned highlights the interest of utility companies in participating in sustainable development from the scientific and practical perspectives. Insights emerge from the multiple analyses as the authors explored utilities' contribution to sustainability-oriented change.

Can environmentally conscious consumers become a driving force in the uptake of energy-use automation? To help answer this question, we collect survey data from samples drawn from the general population in Germany and Spain (combined N = 2864). Self-reported rates of energy-use automation adoption reach 30.0% in the German sample and 41.0% in the Spanish sample. Environmental self-identity, environmental norms, and one's tendency toward environmentally friendly consumer behavior influence preferences for energy-use automation in Germany but not in Spain. We discuss the possibility that this difference could be attributed to energy-use automation becoming so normalized in Spain that psychological characteristics cease to play a significant role in adoption decisions. Certain other individual characteristics and structural conditions are associated with automation technology preferences, particularly age, gender, income, education, and dwelling type.
有环保意识的消费者能否成为采用能源使用自动化的推动力?为了帮助回答这个问题,我们从德国和西班牙的普通人群中收集样本的调查数据(合计N = 2864)。自我报告的能源使用自动化采用率在德国样本中达到30.0%,在西班牙样本中达到41.0%。环境自我认同、环境规范和一个人对环境友好型消费者行为的倾向影响了德国对能源使用自动化的偏好,但在西班牙没有影响。我们讨论了这种差异可能归因于能源使用自动化在西班牙变得如此正常化,以至于心理特征在采用决策中不再发挥重要作用的可能性。某些其他个人特征和结构条件与自动化技术偏好有关,特别是年龄、性别、收入、教育程度和居住类型。

Drivers of district heating's dominance in Sweden's urban areas: A historical perspective 区域供热在瑞典城市地区占主导地位的驱动因素:历史视角

District heating systems are common in the Northern Hemisphere, but their extent and position in heating markets vary. In Sweden, district heating currently supplies more than half of the demand for heating in Swedish buildings, significantly more in urban areas, with most of the district heating systems built between 1970 and 1990, motivated by the possibility of combining heat production with efficient generation of power. This analysis explains why so many district heating systems were built through an analysis of historical policy documents, statistical data, and interviews. The conclusion is that interrelated drivers can explain this expansion. In particular, the energy crises of the 1970s led to concerns about oil dependency. The parallel reduction in oil use and imported fuels also improved air quality. A national referendum in 1980 also began the phase-out of nuclear power, with combined heat and power playing a pivotal role in its replacement. Favourable governmental loans and grants, combined with more coercive regulations and a general sense that building district heating systems was a “sign of the times”, encouraged even smaller and mid-sized cities to build district heating systems. Thus, the foundation was laid to support the strong current position of district heating in Sweden.
区域供热系统在北半球很常见,但其范围和在供热市场中的地位各不相同。在瑞典,区域供热目前满足了瑞典建筑物供热需求的一半以上,城市地区的供热需求明显更多,大多数区域供热系统建于1970年至1990年之间,其动机是将热力生产与有效发电结合起来的可能性。本分析通过对历史政策文件、统计数据和访谈的分析,解释了为什么建立了如此多的区域供热系统。结论是,相互关联的驱动因素可以解释这种扩张。特别是,20世纪70年代的能源危机引发了人们对石油依赖的担忧。同时减少石油使用和进口燃料也改善了空气质量。1980年的全民公投也开始逐步淘汰核电,热电联产在取代核电方面发挥了关键作用。优惠的政府贷款和赠款,加上更加强制性的规定和建立区域供热系统是“时代标志”的普遍感觉,甚至鼓励中小型城市建立区域供热系统。因此,奠定了基础,以支持当前瑞典区域供热的强势地位。

This analysis considers the effects of past and present renewable support mechanisms on solar energy investment in Turkey based on economic conditions. Changes in the costs of solar energy plants due to inflation over time, the effects of the formula coefficients presented, and the advantages/disadvantages compared to the previous program are presented. Due to current high interest rates and inflationary pressures, annual earnings from solar energy investments have been calculated to range from US$ 70,946 to US$ 138,893. The investment payback period varies between 6.2 and 12 years, while the total support amount is 122.59 cents (US$/kWh). We find that the economic policies have negatively affected the predictability and sustainability of solar energy investments. The results are relevant to policymakers and investors. Optimum energy policies are needed for sustainable energy development in Turkey and developing countries like Turkey.
该分析考虑了过去和现在的可再生能源支持机制对土耳其太阳能投资的影响,基于经济条件。随着时间的推移,由于通货膨胀导致的太阳能发电厂成本的变化,所呈现的公式系数的影响,以及与之前的方案相比的优点/缺点。由于目前的高利率和通货膨胀压力,太阳能投资的年收益估计在70 946美元至138 893美元之间。投资回收期为6.2 ~ 12年,总支持金额为122.59美分(US$/kWh)。我们发现,经济政策对太阳能投资的可预测性和可持续性产生了负面影响。研究结果与政策制定者和投资者息息相关。土耳其和像土耳其这样的发展中国家的可持续能源发展需要最佳的能源政策。

This paper investigates the impact of energy poverty eradication on carbon inequality mitigation in China. First, we find that energy poverty positively correlates with carbon inequality, indicating that alleviating energy poverty narrows the inequality of carbon emissions. Second, alleviating energy poverty is especially crucial in regions facing a more deteriorated situation characterized by energy poverty and carbon inequality. Third, environmental protection expenditures are a mediator and can also directly tackle carbon inequality. Fourth, energy poverty inhibits technological innovation and leads to more traditional energy consumption, undermining the energy transition.
本文研究了消除能源贫困对中国碳不平等缓解的影响。首先,我们发现能源贫困与碳不平等呈正相关,说明缓解能源贫困缩小了碳排放的不平等。其次,在能源贫困和碳不平等状况进一步恶化的地区,缓解能源贫困尤为重要。第三,环保支出是一个中介,也可以直接解决碳不平等问题。第四,能源贫困抑制了技术创新,导致传统能源消费增加,不利于能源转型。
