Resources–environment–economy coordinated development (REECD) is important for global sustainable development goals (SDGs). Integrated assessment model (IAM) is widely applied to investigate REECD‐related issues and design policy or technology development pathways. Accordingly, this study reviews existing literatures on the REECD related IAMs in terms of nexus mechanism, classification, theoretical basis and applicability, and puts forward possible expansion dimensions for improving the models. IAMs could be categorized into top‐down ones mainly based on computable general equilibrium and optimization theories, and bottom‐up ones generally based on engineering‐technological and ecology‐environmental analysis. Top‐down and bottom‐up combined IAMs are increasingly employed to evaluate the impacts of policy implementation, technological penetration and behavior modification, in order to improve the accuracy for decision‐making. Meanwhile, IAMs for REECD are need to be further developed to increase its applicability for analyzing high‐resolution and high‐frequency inventories of resource development and pollutant emissions. Existing IAMs should also embrace key resources consumption such as heavy and strategic metals. Due to tighter carbon emission space under 1.5‐degree and carbon‐neutral climate targets, the nexus mechanism of REECD would change significantly in future, which we need to characterize these variations in the models. Furthermore, researchers and developers should pay more attention to model improvement towards the developing and emerging economies.This article is categorized under:Sustainable Development > Emerging EconomiesSustainable Development > GoalsHuman and Social Dimensions > Energy and Climate Justice

Due to the scarcity of freshwater resources in many arid regions of the world, as well as rapidly growing populations and industrialization, various desalination technologies have been developed and enhanced to improve the performance of saline water purification with high quality. Integrating solar energy technologies with desalination systems would alleviate the running out of fossil fuel sources, reduce costs, and improve energy efficiency. Solar‐powered desalination systems could be a viable and efficient method for treating highly saline water for human consumption. Obtaining reliable and accurate design parameters for such hybrid systems plays a significant role in determining the system performance of solar‐driven desalination systems. The present review provides a comprehensive review of various solar‐driven membrane‐based desalination systems to investigate the impact of design and operation parameters for solar and desalination units on the effectiveness of the hybrid solar/desalination system. Recent advancements in utilizing numerous solar energy sources for desalination are analyzed herein. The economic implications of various membrane desalination operations for different solar energy sources are also discussed. It was revealed that the solar system design parameters, desalination unit characteristics, feed water properties, and climate conditions all affect the functionality and productivity of the membrane‐based solar‐powered desalination system. The feed pressure, number and shape of membranes, and the integrated solar system, all have significant impacts on the performance of the hybrid system. This article provides a pathway for desalination researchers to select the optimal design and operation parameters for hybrid solar‐powered membrane‐based desalination systems. Notably, they are found more feasible and sustainable than traditional desalination processes.

The world is currently dealing with an energy crisis, primarily due to heavy reliance on finite fossil fuels and the associated rise in energy demand. In response to this crisis, replacing heavy reliance on finite fossil fuels with biodiesel has gained attention as an alternative solution. Sub‐Saharan African (SSA) biodiesel studies have traditionally focused on improving transesterification but overlook socio‐economic, policy, and institutional impacts on production sustainability. To address this gap, this study comprehensively reviews the sustainability of transesterification‐based biodiesel production from nonedible feedstocks in SSA. The study's incorporation of socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks reveals the complex prospects and challenges facing biodiesel production in SSA. The findings reveal that sustainability challenges in SSA stem from a lack of an integrated approach, resulting in conflicting local and global policies. The study determines that neglecting socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks weakens regional biodiesel production sustainability. Evidence from the study emphasizes the role of an integrated approach in promoting biofuel production, establishing markets, and improving the livelihoods of the region's population. Furthermore, the review shows that transesterification can yield biodiesel with comparable physical properties to conventional diesel, making it a wide region's favored option.This article is categorized under:Human and Social Dimensions > Energy and Climate JusticeSustainable Energy > BioenergySustainable Development > Goals

The energy rebound effect, characterized by increasing energy use despite enhanced efficiency, has emerged as a complex interdisciplinary topic in the literature, reflecting its significance in both production and consumption sustainability. Recognizing the pivotal role of academic research in shaping energy management strategies and policies, this study conducted a comprehensive bibliometric review, accessing 530 articles from major citation indexes. This analysis provides insights into the evolution of the energy rebound field and potential future directions. Understanding the existing literature on the rebound effect serves as a valuable foundation for forthcoming research endeavors, addressing the intricate challenge of reconciling energy efficiency with sustainable energy consumption and production. The review explores the extensive literature on the energy rebound effect, highlighting a predominant focus on residential (e.g., cooling, heating, lighting, transportation) and industrial energy consumption in the majority of studies. Empirical applications primarily emphasize the measurement of the energy rebound effect, with a notable trend of increasing research concentration in China in recent years. Additionally, there is a growing body of economy‐wide analyses in this field. However, the literature exhibits complexity in both the analyses conducted and the methods employed for measuring the rebound effect. Research gaps are apparent, numerous studies tend to concentrate solely on the rebound effect at the overall energy consumption level, neglecting variations in energy types and the behavioral patterns of economic actors. Furthermore, despite consistent findings of a higher rebound effect in developing nations, there is a noticeable lack of scholarly literature addressing this issue about these countries.This article is categorized under:Sustainable Energy > Energy EfficiencyHuman and Social Dimensions > Behavioral SciencePolicy and Economics > Governance and Regulation

Supercapacitors have emerged as drivers for the advancement of green energy technologies in energy storage systems and energy‐efficient devices. Their ability to rapidly acquire and deliver charge at high current densities and long cycle life is key. However, their high self‐discharge rates prevent their potential use in a wide range of applications, especially when utilizing commonly available activated carbon electrodes. Addressing this bottleneck is hindered by the lack of a comprehensive understanding of the self‐discharge processes. In this article, we provide a concise overview of various types of supercapacitors, followed by an exploration of self‐discharge phenomena within electrochemical systems. Recognizing the limited understanding at a molecular level, this article focuses on characterizing self‐discharge through the nature of the gradual decline in cell potential. We then survey the use of diagnostic methods in the literature to elucidate one or more controlling mechanisms operating during self‐discharge, facilitating a rational search for mitigation. We conclude by emphasizing the need for caution when interpreting controlling mechanisms solely based on cell potential measurements over time.This article is categorized under:Emerging Technologies > Energy Storage

The climate, ecological, and energy crises require change in our political, economic, and societal systems to ensure we decouple humanity from a reliance on fossil fuels, prevent rising carbon dioxide emissions, and develop sustainable solutions for people and the planet. As well as technical processes, renewable energy transitions are processes of social, environmental, and economic change which have the potential to challenge the status quo. This status quo determines who benefits from energy, where wealth is created, and the level of inequality between stakeholders within our energy systems. The politicization of energy transitions motivates stakeholders to engage in the policymaking process to ensure any trade‐offs associated with policy changes benefit them. Bioenergy is unique amongst renewable energy sources as it is inherently linked to biomass extraction from our natural environment and because biomass is the only source of renewable carbon. However, this further politicizes its use and is a source of controversy in public debate. Polarized perspectives in the public debate on biomass policy allow stakeholders to assert themselves as experts on the topic and to make authoritative claims that further their interests to influence policy development. Therefore, political and economic drivers shape and influence the sustainability and success of proposed policies. Despite this, there is little research into the nontechnical factors influencing the design of sustainable biomass policy for net zero. This research highlights how political economy impacts the success of renewable energy technologies in replacing fossil fuels and the implications for using bioenergy.This article is categorized under:Sustainable Energy > BioenergyPolicy and Economics > Energy TransitionsClimate and Environment > Net Zero Planning and Decarbonization

Among the total 17 UN-SDGs (sustainable development goals) proposed by the United Nations, the goal 7 basically ensures easy global availability of sustainable, clean, cost effective, reliable, and modern energy. Researchers are primarily concentrating on renewable energy sources in this direction since they are sustainable, clean, and environmentally friendly. But there are numerous obstacles, such as their low reliability, irregular nature, remote availability, and so forth, that prevent them from being widely used in commercial applications. Combining these renewable energy sources with effective and affordable energy storage technologies can be a promising solution to approach concerns including rising energy consumption, reliable and consistent electric power, and better grid stability. Modern energy storage systems such as electric double layer capacitor (EDLC) and lithium-ion batteries have a great deal of potential for a wide range of applications. Carbon-derived materials are the most flexible and fundamental materials for the storage and conversion of modern energy. Since it requires the pyrolysis and activation of expensive starting materials like wood, petroleum, and coal, the commercially produced activated carbon is costly and unsustainable. Due to rapidly increasing amount of plastic waste and the requirement for sustainable development, the conversion of waste plastics into valuable yet inexpensive carbon nanomaterials have attracted significant research interest. Their outstanding capability for charge accumulation and transportation is due to their enormous surface area, high chemical stability, and electrical conductivity in combination with low density. The present article examines the necessity and the efforts undertaken to develop supercapacitors and Li-ion batteries as sustainable modern energy storage devices using recycled waste plastic.

Flexible supercapacitors with hybrid anodes have gained significant attention in energy storage research, owing to their remarkable specific capacitance, outstanding power and energy densities, rapid charging-to-discharging rates, and superior flexibility. However, bare carbonaceous anodes exhibit limited capacitive performance, resulting in low energy density. To address this issue, recent efforts focus on hybridizing carbonaceous anodes with metal-based active materials to enhance their electrochemical performance. This part of review comprehensively outlines the available options of carbonaceous materials used as substrates for constructing hybrid free-standing flexible anodes. Various persuasive approaches are discussed, highlighting their effectiveness in enhancing the electrochemical performance of carbonaceous substrates. In addition, this piece of work provides an insight into the possible configurations of such devices for real-life applications.
