The generation of fine coal particles during mining and processing presents significant environmental and logistical challenges, particularly in coal-dependent, developing countries like South Africa (SA). This review critically evaluates the technical viability of fine coal briquetting as a sustainable waste-to-energy solution within a SA context, while drawing from global best practices and comparative benchmarks. It examines abundant feedstocks that can be used for valorization strategies, including fine coal and agricultural biomass residues. Furthermore, binder types, manufacturing parameters, and quality optimization strategies that influence briquette performance are assessed. The co-densification of fine coal with biomass offers a means to enhance combustion efficiency, reduce dust emissions, and convert low-value waste into a high-calorific, manageable fuel. Attention is also given to briquette testing standards (i.e., South African Bureau of Standards, ASTM International, and International Organization of Standardization) and end-use applications across domestic, industrial, and off-grid settings. Moreover, the review explores socio-economic implications, including rural job creation, energy poverty alleviation, and the potential role of briquetting in SA’s ‘Just Energy Transition’ (JET). This paper uniquely integrates technical analysis with policy relevance, rural energy needs, and practical challenges specific to South Africa, while offering a structured framework for bio-coal briquetting adoption in developing countries. While technical and economic barriers remain, such as binder costs and feedstock variability, the integration of briquetting into circular economy frameworks represents a promising path toward cleaner, decentralized energy and coal waste valorization.

Energy poverty, resulting from poor energy efficiency and economic and social barriers to accessing appropriate, modern, and sustainable energy services, remains a critical issue in Jordan, a country facing growing climate pressures, particularly given its history of rapid urbanization. This study examines energy poverty through a multidimensional lens, considering its spatial and socio-demographic variations across Jordan. Drawing on data from 19,475 households, we apply a novel energy poverty index and binary logistic regression to analyze key determinants of energy poverty and discuss their intersection with climate vulnerability. The energy poverty index (EPI) is structured around four pillars: housing, fuel, cooling, and wealth. The results show that 51% of households in Jordan are affected by energy poverty. Contributing factors include geographic location, gender, age, education level, dwelling type, ownership of cooling appliances, and financial stability. The results indicate that energy poverty is both a socio-economic and infrastructural issue, with the highest concentrations in the northern and southern regions of the country, areas also vulnerable to climate risks such as drought and extreme heat. Our findings emphasize the need for integrated policy approaches that simultaneously address income inequality, infrastructure deficits, and environmental stressors. Targeted strategies are needed to align social and climate policies for effective energy poverty mitigation and climate resilience planning in Jordan. Full article

Retrofitting the existing housing stock to a high level of energy efficiency will not be limited to achieving the decarbonisation of 80.3 MtCO2e residential emissions and reducing fuel poverty in 4.16 million households, but also improving the health and well-being of UK residents and their overall quality of life. The current progress of housing retrofitting is poor, at less than 1%. The UK expects to achieve net zero by 2050, and the challenge is immense as there are more than 30 million houses. The challenge is similar in other global contexts. Even if the required technology, supply chain, skilled labour, and finance could have been provided, the retrofitting would not move forward without positive engagement from the clients. Proper strategies are required to retrofit at scale. Focusing on the challenges of stakeholder engagement in housing retrofitting, this study focused on developing a hybrid one-stop shop solution through design science research. A theoretical artefact and an empirical system requirement specification document were developed to propose a one-stop shop solution. This was tested through retrofit industry stakeholders. Findings reveal that the one-stop shop model will be a good answer to retrofitting at scale, providing the resident engagement of 30.1 million households. The model can support residents with or without computer literacy due to its hybrid approach. The proposed theoretical and industrial models can be used as base models for developing one-stop shops for housing retrofitting by adapting them for context-specific requirements. Full article

The subtropics are affected by severe climate change, which may induce heat stress in animals. Moreover, the region is significantly seasonal; hence, mitigating climate risks and implementing climate adaptation measures are necessary. Sustainable Development Goals 1, 2, and 13 call for no poverty, zero hunger, and climate action. These are the most severe problems affecting food security in the modern world. Food security refers to a situation in which all people have physical, social, and economic access to sufficient, proper, and healthy food that satisfies their dietary requirements. Nevertheless, the projected increase in the human population implies a greater demand for employment opportunities; hence, developing countries are building more industrial areas. The burning of fossil fuels in various industries potentiates climate change and environmental pollution. It is predicted that the ecological temperature will increase by almost 2.3–4.8 °C by 2100 due to climate change. Agriculture and animal products remain vital in Africa as drivers of the economy and transformation for sustainable livelihood and development. Sheep production has long been used as a source of income and livelihood and provides jobs for people who live in rural areas. It is also sometimes used for ritual ceremonies and to pay penalties to local authorities. Nevertheless, sheep have been identified to be sensitive to heat stress, characterized by low reproductive performance, low microbiota quantities, and poor general health. There are different strategies for mitigating heat stress; however, many smallholder farmers have limited access to education and lack the financial support required to incorporate artificial shade and plant trees for shade to limit heat stress. In this review, we aim to understand the effects of environmental heat stress on sheep production and reproductive performance. Based on this review, it can be concluded that heat stress can threaten food security if not addressed, especially for farmers who depend on sheep rearing. As a result, future studies are recommended to understand different adaptation methods that can be used to mitigate the heat stress effect on sheep productivity, reproductivity, and general health.

Energy poverty focuses on energy affordability in developed nations but is most often used in the developing world in the context of a lack of access to electricity, clean cooking fuels, or technologies. About 1.2 billion people still lack access to electricity and nearly 40 per cent of the world’s population lacks access to clean cooking fuels. In addition, climate change mitigation strategies must be applied to a complex and diverse socio-technical landscape that varies across and within countries. Energy poverty is among the most pressing issues to be addressed within these strategies; however, due to the complexity of its causes, there is no commonly agreed upon evaluation approach or holistic set of indicators for its quantitative evaluation. In this study, a comprehensive literature review is undertaken on energy poverty measurement methods and definitions, and factors that cause energy poverty. Through this, exogenous and endogenous factors that are often overlooked in the assessment and prediction of energy poverty are identified. The need for an energy poverty prediction framework is identified, incorporating missing perspectives and elements needed to implement future energy poverty projections to enable proactive policy development. Missing perspectives included an increase in energy demand associated with the development of innovative technologies including artificial intelligence and automation, increasing fuel prices, and exogenous factors such as rising temperatures and increased acute disasters and endemic structural failures associated with climate change leading to employment impacts, all of which may be critical to the accurate prediction of energy poverty.

Concerns sparked by the US opioid epidemic have led to increased attempts to reduce England’s overall opioid consumption. Variations in health literacy across the country have led to differing prescribing practices, with increased chronic conditions appearing in areas of increased socioeconomic deprivation. This review investigated the relationship between increased opioid utilization and increased socioeconomic deprivation, aiming to highlight areas of England which have the highest opioid consumption. The review has investigated a range of socioeconomic factors, such as unemployment and fuel poverty, which have consequently influenced the higher frequency of opioid prescribing in areas where these factors were highest. Opioid abuse was most prevalent in areas with higher levels of deprivation. Geographically, areas with the highest levels of deprivation, and consequent opioid consumption, were situated in the North of England, with cities like London having a significantly lower consumption rate in comparison. These trends are a good starting point when designing future opioid epidemic-prevention strategies, as specific areas can be targeted to propel a reduction in opioid prescribing and addiction and thus decrease the likelihood of an opioid crisis forming. Although a longitudinal study would have strengthened the findings of this review, it was not feasible due to practical constraints. Full article

This article examines Greek households’ energy and transport poverty and vulnerability, two concepts often intertwined in policy, making use of both single and composite indicators. The methodology employed aligns with the European Social Climate Fund regulation, using household income from economically active members and the share of expenditures on fossil-based energy use in buildings and transport, as well as the required investment costs in energy efficiency improvements for dwellings or transport decarbonization measures. Through these indicators, the proportion of energy-vulnerable households in Greece ranges from 19% to 40%, while transport vulnerability varies between 22% and 43%. Notably, the analysis reveals that households in higher income categories can still be highly vulnerable, depending on household size, composition and dependency, which impact energy and transport needs. As such, the research findings reveal that the current legislative frameworks may not fully capture the vulnerability of certain demographic groups in the event of additional costs of fossil fuels due to new climate policies. Therefore, it is strongly recommended that policymakers adjust criteria to better target vulnerable households based on their unique characteristics and needs, and use improved data collection systems to monitor energy and transport poverty and vulnerability.

Energy poverty has evolved into a topic of global concern affecting both developing and developed countries. Energy poverty deprives the potential of numerous women to participate in family, communal, and economic activities. While energy poverty is a commonly studied subject, the existing literature often overlooks its gender dimension, specifically the effects on women. This systematic review aims to fill the current research lacuna by shedding light on the multifaceted consequences faced by women due to energy poverty. To this end, numerous articles from Scopus and Web of Science are fully analysed. The findings demonstrate the impacts on multiple aspects of women’s lives, such as health, emotional well-being, income, increased workload, and the perpetuation of inequality. Though the challenges seem a bit different in the Global South and North from a boarder perspective, coherent policies that enhance women’s empowerment with economic opportunities could minimize the potential risk of energy poverty. The review underlines the urgency of integrating a gender perspective, emphasising the necessity of interdisciplinary methods that connect energy and gender studies differently in both the Global North and South. The finding also highlights the role of socio-economic conditions, cultural norms, and the division of labour in increasing women’s vulnerability. This review highlights the crucial significance of gender-inclusive approaches in understanding and tackling energy poverty. Full article

In the forthcoming decades, the energy sector will confront significant transitions related to climate change, supply stability, and energy poverty. The initial two aspects have undergone thorough scientific analysis, whilst the third has received comparatively less analysis despite its significant impact on the lives of millions. Using a systematic literature review, laws and regulations and document analysis, and based on the assumption of an energy ladder, this study provides an overview of energy poverty and its implications. The research focuses on energy poverty in developed countries and answers whether the European Union’s implemented and planned actions to reduce greenhouse gas emissions cause energy poverty. Based on the Polish case, the study shows that the EU’s scheduled actions aimed to stabilise climate change, although right in intention, require modification because they do not fully consider the significant economic and energy development diversity of the European Union Member States and may increase energy poverty affecting the European inhabitants. The findings show that due to the implementation of the EU Emission Trading System 2 in 2027, transport costs may increase by almost one-third, which will raise the prices of goods and services and affect energy poverty. This study develops the stream of research on energy poverty, modifies the concept of the energy ladder and shows threats resulting from the ETS2 implementation. The paper proposes the avenues of future research. Full article

Energy poverty is a new issue in the world and the developing nations are no exception. The West African nations exhibit serious problems on the accessibility and affordability of energy in rural areas and in urban areas. The major concern is the conventional fuels that they widely use as alternatives once faced with energy access problems. These fuels damage the surroundings and deteriorate the health systems of people. Therefore, this study is motivated in addressing the energy poverty issues in West African nations and informing vigorous mechanisms that are essential in solving this crisis. The lack of studies and the lack of robust policies to inform ways that can be adopted to lower energy poverty in this region require new contemporary studies to be presented. Thus, this study examines the interplay of green finance, income and technology in reducing energy poverty in West African nations. The fourteen West African nations are therefore examined and their data for the period 2004 to 2020 are used. Data analysis methodologies adopted ensure the employment of the “method of moments quantile regression” technique to ensure that problems of “cross-sectional dependence” and “heterogeneity” are overcome. Our findings shows that energy poverty in West African nations could be lowered with advancements in technology, utilization of green finance and improvements in the income levels in this region by magnitudes of 17 to 21 units, 0.15 to 0.82% and 0.39 to 1.47 units, respectively. The income generated from the natural resources and foreign direct investment inflows fails to reduce energy poverty and worsens it by magnitudes of 0.33 to 0.48 units and 0.12 units, respectively. Therefore, we show that improvements in institutional quality and the adoption of green technological tools are key to reducing energy poverty. Full article

Central African nations, just like other African nations, have serious energy poverty problems, both in the rural and urban settings. With increased energy-accessibility problems, citizens have resorted to the use of conventional fuels, causing severe environmental degradation and affecting the health systems due to pollution. In this study, we address how energy poverty is alleviated with technology, natural resources and improved institutional quality. The interplay between these factors in improving energy accessibility is not widely understood; hence, key policies are lacking in the field. The data of Central African nations for the time period from 2004 to 2021 are utilized. The data are also analyzed with the ‘Methods of Moments Quantile Regression’ technique, ensuring the correction of ‘cross-sectional dependence’ and ‘heterogeneity’ that exists. The key findings depict that natural resource rent, government effectiveness and technology help in lowering energy poverty in Central African nations. Economic growth increases energy poverty, while green finance and foreign direct investment do not present a significant effect on energy poverty. Therefore, natural resources are a blessing in improving the accessibility of energy in this region, and this is also made possible with advancements in sustainable technology and proper institutional quality.

Agroforestry improves the stability and productivity of agro-ecosystems and reduces environmental pressures, making it extremely flexible and useful in a variety of physical and social contexts. This practice is crucial to farmers’ livelihoods on both an ecological and economical level. Using an interview schedule, data were gathered from 170 heads of rural families who were chosen at random. Of the responders, the majority (77.5%) were young (25 to 40 years old). Of those who had completed more than five years of schooling, only 46.7% were literate, while a sizable majority (53.3%) were illiterate. For the vast majority of responders (62.4%), farming was their primary source of income. Given that over 54% of the respondents only owned up to five acres of land, small farming was extremely common. The majority (61.3%) were considered poor with a monthly income of less than PKR 18,000. “good source of fuel wood” was placed at the top (mean = 3.1%) when it came to the effect of agroforestry on the food security of rural households. One of the main obstacles was having a small land holding (mean = 2.52). The majority of respondents believed that the primary benefit of agroforestry was a reduction in soil loss. The amount of land held, income source, and educational attainment all significantly correlated with the perception of poverty. The study found that the best way of sustainably assuring food security in the study area and satisfying rural residents’ needs for food for extended periods of time is to incorporate agroforestry into the current farming system.

Although Moringa oleifera Lam. (Moringaceae) is a multipurpose tree with remarkable nutritional and therapeutic benefits, it is undervalued and neglected in Kenya, as the local people associate it with famine and poverty. The present study aims to assess and document the traditional knowledge on use and management as well as production constraints of the species among the Mijikenda community in Kilifi County, Kenya. We found that the plant is locally used as food and medicine for various ailments, including diabetes, high blood pressure, ulcers, stomach aches, and body pains. In addition, the plant is used for fencing and as a source of fuel. Watering and pruning were found to be the main management practices of the plant. Slightly more than half (51.3%) of the respondents reported pests as a constraint in growing the plant, while the bitter taste (60.5%) and small leaves (36.8%) were deterrents to its consumption and harvesting, respectively. More than half (55.3%) of the respondents had between one and five trees in their compounds, indicating a low preference for the plant compared to major crops. The plant species is undervalued compared to locally grown major crops, highlighting the need for concerted efforts to raise awareness of its potential benefits and address the production challenges.

This study investigates the multifaceted issue of energy poverty, focusing on its spatial and socioeconomic dimensions, with a particular emphasis on the case of Chile. Despite global initiatives like Sustainable Development Goal 7, which advocates for universal access to affordable and reliable energy, millions remain vulnerable to energy poverty. In Chile, this phenomenon is exacerbated by geographic and climatic variability, resulting in significant disparities in energy access, affordability, and efficiency. Using a multidimensional framework adapted from Bouzarovski and Petrova, we assessed energy poverty through factors including household income, fuel costs, energy infrastructure reliability, and regional climate needs. This analysis integrated composite indicators to map vulnerability at the regional level, highlighting high-risk areas primarily in the central and southern regions, where low incomes and dependency on biomass for heating amplified exposure occur. The findings reveal that approximately 4 million Chileans face a high risk of energy poverty, underscoring the need for regionally tailored policies that address both immediate economic constraints and structural energy inequalities. This research contributes to a comprehensive understanding of energy poverty in Chile and offers policy recommendations aimed at reducing socioeconomic disparities and achieving sustainable, equitable energy access.

This study investigates the multidimensional aspects of energy poverty in Pakistan from 2000 to 2022, specifically evaluating the direct, indirect, and total effects of socioeconomic and environmental factors. We employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the impacts of income, population, governance quality, energy intensity, fuel prices, and renewable energy consumption on energy poverty. The study further contributes by examining the mediating role of governance quality and developing the World Governance Indicators (WGI) Index. The findings indicate significant negative effects of energy intensity and renewable energy consumption on energy poverty. Conversely, population growth and income levels demonstrate positive effects, contradicting conventional economic development and energy access assumptions. Governance quality establishes direct and indirect effects that mediate most relationships between independent variables and energy poverty. Bootstrapping analysis confirms the significance of governance quality as a mediator. The model describes significant energy poverty variance with robust predictive relevance. This study emphasizes the need to adopt a comprehensive strategy to decrease Pakistan’s energy poverty by articulating socioeconomic, environmental, and governance factors. Our findings offer valuable information for policymakers to achieve UN Sustainable Development Goal 7, embarking on governance reforms, promoting sustainable growth, and enforcing investments in energy efficiency and renewable sources as Pakistan approaches the 2030 SDG 7 deadline.
