The widespread use of fossil fuels in production processes, along with a heavy dependency on carbon-based materials in firms that emit substantial amounts of carbon dioxide equivalent, poses a global threat to both environmental and economic sustainability. A better understanding is needed regarding the relevance of clean energy innovation and its direct and indirect impact on lowering carbon footprints in the existing body of research. This study employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology for a systematic review, followed by an in-depth evaluation of findings. The review examined 153 scholarly articles published between 2018 and 2023, aiming to assess the evolutionary nuances of clean energy innovation in the context of global decarbonisation. Results indicate that 58.5 % of evaluated hypotheses demonstrate a positive association between corporate environmental and financial performance, whilst 31.4 % show a negative impact on profitability. The remaining 10.1 % yield mixed findings. Notably, there is a paucity of research on the potential moderating or mediating effects of clean energy innovation on this relationship. This study contributes to the scientific corpus by identifying two understudied research areas. Firstly, Scope 3 emissions have a substantial and positive effect on the major corporations' overall financial performance. Secondly, further research is warranted to determine how clean energy innovation can moderate or mediate the relationship between eco-innovation strategies and company performance. This research is vital for understanding clean energy innovation's potential as a pathway toward decarbonisation.

New technologies are necessary for energy system transition and meeting climate targets. However, obstacles to social acceptance, often linked to limited understanding and awareness, impede their integration. This article focuses on the acceptance of seasonal thermal energy storage technologies. This energy technology enables the storage of surplus heat in summer for heating in winter and the transfer of cold from winter to summer for cooling purposes. Combining theoretical insights from research on public opinion formation and social acceptance, this article constructs a model to explore how different information framings and formats influence individual opinion formation and the social acceptance of these technologies. It presents data from an experiment conducted in Switzerland through two online cross-sectional surveys (N = 1749; N = 614). The participants were given varied information framing conditions and formats. Based on independent sample t-tests, Kruskal–Wallis tests, and generalized structural equation models, the findings reveal that providing identical information in a video rather than as text increases general technology acceptance directly, as well as indirectly through reduced information complexity. Emphasizing technological readiness also positively affects general technology acceptance. However, these effects do not extend to more concrete market and community acceptance. The research highlights the significance of tailored and accessible information in facilitating information processing for unknown (energy) technologies in enhancing their social acceptance.

As Africa approaches the 2.5-billion population mark by 2050, its demand for energy and resources becomes both a challenge and an opportunity for climate change mitigation. Can the additional billion energy users help to achieve global sustainability as the lead users of timely investments in renewable energy? This study proposes investments – specifically, investments in renewable energy development in African countries – as a leverage point in the global effort to avoid the worst effects of climate change. The analysis asks how the capacity for renewable energy production can meet the rising demand for energy in the context of growth faced by African countries., and combines projections for population growth, urbanization, and economic growth. The study emphasizes how bridging Africa's renewable energy finance gap can shift the set of expected long-run scenarios for the global climate crisis.

Plant factory with artificial light is proved to be a promising technology for relieving the food crisis, especially in urban areas or arid regions endowed with abundant resources. However, lighting and heating, ventilation, and air conditioning systems of plant factory with artificial light have led to much greater energy consumption than open-field and greenhouse farming, limiting the development and global application to a wider extent. Researches in the last few years focus on the optimization of energy consumption to develop and promote the plant factory with artificial light technology with reduced energy usage. The review in this work seeks to overview energy consumption analysis as well as energy-saving technologies that can enhance the feasibility of the plant factory with artificial light. Specifically, the paper reviews various energy-saving designs and case studies, indicating that the lighting energy-saving design mainly focusing on the optimization of light intensity, light spectrum and light period can save up to 45 % energy consumption based on experiments, while heating, ventilation, and air conditioning systems optimization can save up to 50 % energy consumption mainly based on simulation. Future studies on efficient equipment, artificial intelligence technology, renewable energy integration and advanced energy material application are important for developing plant factory with artificial light. These promising improvements will provide more crop yield with lower energy consumption and carbon emissions to achieve resource sustainability and relieve the food crisis.

China is in the process of constructing the world's largest scale of electric vehicle charging stations (EVCS) to promote the long-term growth of the electric vehicle (EV) market. Installing photovoltaic (PV) on the rooftops of EVCS parking areas can supply clean electricity to these stations, alleviate the strain on the electrical grid, and reduce carbon emissions. Consequently, it is essential to assess the technical, economic, and carbon reduction potential associated with the integration of PV technologies in EVCS. This study examines the potential for PV integration and energy consumption across 156 EVCS located in Wuhan, utilizing data on charging hours, solar irradiation, and geographic information. The findings indicate that the EVCS in Wuhan can accommodate PV systems with capacities of 19.91 MWp and 23.49 MWp at horizontal and optimal tilting angles, respectively, generating 23.96 GWh and 37.58 GWh of electricity. The energy consumption of the EVCS is analysed through year-round production simulations based on various operational targets. The results of the economic potential assessment reveal that the PV to EVCS exhibits superior economic efficiency. In terms of carbon reduction, the horizontal and optimal tilts can achieve reductions of 106.82 kt and 110.48 kt, respectively, contingent upon the operational target. The discussion focused on the future scenario indicators and the feasibility of achieving 100% PV energy utilization in EVCS. This study demonstrates that the integration of EVCS and PV systems serves as a significant contributor to achieving deep decarbonization in both the transportation and power sectors.

Bioenergy is a sustainable alternative that has gained prominence in recent years, primarily for enabling the reduction of greenhouse gas emissions. Currently, biomass is the most abundant raw material for bioenergy and biofuel production, with the agro-industrial sector generating large quantities of this resource. The state of Rio Grande do Sul, located in southern Brazil, stands out as the country's largest peach producer, with an estimated production of 128.6 thousand tons per year. The central objective of this study is to provide a bibliometric overview and a technical analysis of the potential for biogas and biohydrogen production from peach industry residues generated in Rio Grande do Sul, considering that this biomass is frequently discarded despite its high energy potential. The estimated potential for biogas production from peach pomace is 1 million m³/year, with a chemical energy potential of 8.63 MWh/year. The total estimated hydrogen production for the state is 247 tons of H₂. Wind and solar energy can be complemented by the generation of bioenergy from agro-industrial residues, enabling a broader energy transition in line with Sustainable Development Goal 2, 7, 12 and 13. Furthermore, bioenergy emerges as a viable solution to reduce social poverty, energy scarcity, the economic risks associated with the use of fossil fuels, and environmental degradation by reducing carbon dioxide emissions.

Offshore wind farms generate electricity at relatively low cost and are regarded as a major contributor to net zero targets, supporting United Nations Sustainable Development Goals 7 and 13. However, some seabird species are at risk of colliding with turbine blades or being displaced by offshore wind farms. The European Union and the UK have legal requirements for wind farm developers to implement compensation measures if their developments are likely to have an adverse impact on the integrity of seabird populations in Special Protection Areas. Compensation measures that have been established have carbon costs and are applicable only to a restricted group of species, reducing the overall benefits. Here we make a novel suggestion that placement of seaweed farms close to selected seabird colonies could act as compensation for mortality associated with offshore wind farms. Many seabirds construct nests from seaweed that they collect at sea. These birds may also use plastic waste in nest construction. Plastic can kill seabirds by entanglement. Increasing availability of seaweed could reduce this mortality by reducing use of plastic in nest construction. This novel approach has multiple advantages over other forms of compensation. In particular it could benefit northern gannets Morus bassanus, a species considered especially at risk from impacts of offshore wind farms but not addressed by existing compensation measures. Seaweed farming as a compensation measure could also contribute to carbon sequestration and provide other environmental benefits as well as promoting the growth of an industry not yet well established in European seas.

Green electricity trading is an effective means to promote the energy transition and sustainable development. The promotion of green electricity trading can strengthen the rigid requirements for specific industries, especially high-energy-consuming industries. Most previous studies have considered only the influence of individual characteristic factors on green electricity purchase intentions and have not investigated the influence of external green electricity trading mechanisms. To address these limitations, this study takes enterprises in high energy-consuming industries as the research objects and uses the choice experiment method to conduct a questionnaire survey. Using data from 200 enterprises in China's high energy-consuming industries, logit models are applied to examine the impact of changes in the design of the enterprise green electricity trading mechanism on the participation willingness of enterprises in high energy-consuming industries to purchase green power. The results show that the green electricity trading attributes that affect the participation willingness in descending order are as follows: transaction object > participating market > penalty mechanism > supplementary mechanism. In addition, an increase in the annual energy consumption of enterprises has a negative effect on their participation willingness. Finally, policy suggestions such as green electricity trading mechanism refinement and demand forecasting are proposed to improve China's green power trading market and provide a reference for the construction of green power trading in other countries.

As newer generations of electric vehicles get to market, more electric vehicles with out-of-use components will emerge. Some of these electric vehicles will have components that no longer pass automotive standards. This study establishes a method of assessing the second life potential of end-of-life traction power converters repurposed for stationary applications like solar energy conversion systems. Traction converters in electric vehicles are subject to aggressive mission profiles as the vehicle can go from idle to full power acceleration and surge power conditions within seconds. Hence, these traction converters experience electrothermal stress profiles that degrade the electrical and thermal impedance of the modules thereby reducing the efficiency. The converters are considered unusable after the electrical and thermal impedance of the module increases by at least 20 %, which ideally should occur after the vehicles useable life. However, with suitable de-rating in less stressful stationary applications, end-of-life traction converters could still be capable of high efficiency and reliable performance. Using electrothermal simulations and reliability modelling, this study demonstrates that a 300 kW traction inverter with 20 %, 40 %, 60 % higher thermal and electrical impedance (corresponding to 1.6, 3.4, 5.5 % reduced efficiency in vehicle drivetrains) is capable of higher than 98.5 % efficiency when used as a solar inverter for micro-grid applications. A method of estimating power module lifetime consumption in the second life application has been proposed indicating that demand side management is critical for maximizing the second life of the converter if vehicle charging is integrated into the photovoltaic powered micro-grid.

Using electrothermal simulations and reliability modelling, this study demonstrates that a 300 kW traction inverter with 20 %, 40 %, 60 % higher thermal and electrical impedance (corresponding to 1.6, 3.4, 5.5 % reduced efficiency in vehicle drivetrains) is capable of higher than 98.5 % efficiency when used as a solar inverter for micro-grid applications. A method of estimating power module lifetime consumption in the second life application has been proposed indicating that demand side management is critical for maximizing the second life of the converter if vehicle charging is integrated into the photovoltaic powered micro-grid.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"210 ","pages":"Article 115238"},"PeriodicalIF":16.3,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the challenges of energy transition necessary for sustainable development, incumbents must implement innovations, some of which are radical compared with their current competence-base or market solutions. This requires a thorough understanding of the prerequisites for implementing innovation. The literature on the factors influencing incumbents' implementation is vast and dispersed across multiple fields, with sometimes contradictory findings. As a result, it is difficult to get a clear picture what influences innovation implementation. This study explores the factors that condition the propensity of incumbent firms to implement radical innovations relevant to the energy transition and examines how these factors influence. A systematic literature review was conducted, covering 43 articles. The study identifies and explains the influence of 20 such factors on implementation. Nine factors are firm-external and relate to the themes of socioeconomic-political pressure, innovation conditions and industry conditions. Eleven factors are firm-internal and relate the themes of organisational properties, absorptive capacity, and internal alignment with the innovation. Causal relationships between these internal and external factors were discovered, as well as complementary influences on implementation. Potential future research venues are proposed, including scarcely recognized factors that merit further attention, factor complementarity and interdependency, and empirical gaps in terms of geographic context. It also offers policy and management implications, concluding that to gain a thorough understanding of the prerequisites for implementation, it is necessary to simultaneously consider a wide range of factors and their interconnectedness.
