Thus, the present study is intended to explore the dynamic role of energy efficiency, green energy, green technology, and environmental policy stringency for achieving carbon neutrality goals in the presence of other variables, such as economic growth. A series of advanced econometric techniques, including a cross-sectional dependence test, a second generation unit, a joint correlated effect-mean group (CCE-MG), and an augmented mean group (AMG), were adopted to assess the panel data from 1990 to 2020 empirically. The initial finding indicates the existence of cross-sectional dependence, data stationarity, slope heterogeneity, and panel co-integration among the variables. Lastly, based on the nature of the panel data as cross-section dependence in the data, CS-ARDL was preferred over traditional econometric techniques. Additionally, the CS-ARDL more efficiently tackles the unobserved elements and heterogeneity across the cross sections. Findings exhibited that energy efficiency, green energy, and environmental policy stringency are promising factors for addressing the growing carbon emission problems. Moreover, we also applied non-linear ARDL, and the finding revealed that a one percent positive change in energy efficiency, EPS, and GDP would have a negative impact on carbon emission, and vice versa. Additionally, the Dumitrescu-Hurlin causality test revealed a causal relationship between environmental policy stringency, energy efficiency, green technology, and green energy consumption in the BRICS countries. Based on the current study's findings, diverse and feasible policy options are recommended for attaining carbon neutrality goals.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"57 ","pages":"Article 101546"},"PeriodicalIF":7.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the length of purchase contracts and the FiT calculation method during the contract period were revised. However, because of the lack of experience and fast growth rate, some serious problems such as the shortage of funding and the system failures caused by the weakness of prerequisite standards and infrastructures are predicted in the future. These problems seem to be more critical, especially for PV systems that don't have a long history in Iran. For this purpose, a system dynamic approach was used to investigate the economic, social, and political aspects of this system. Monocentricity of renewable energy support policies has caused any problem to directly or indirectly cause the system to fail. For example, in this study, the lack of a reference laboratory and relevant standards for photovoltaic systems have been investigated. This study aims to investigate how the lack of reference laboratories and non-compliance with relevant standards will hinder the development of photovoltaic systems. To overcome this problem, in addition to strengthening the issues related to standards and laboratories, it is necessary to widen the range of support policies.

The production of bioethanol from food waste might result in a long-lasting method that would satisfy both the growing population's energy needs and the problem of disposing of food waste. According to estimates, one-third of the food produced worldwide, or 1.3 billion tonnes annually, is wasted. Biofuels like bioethanol reduce dependency on fossil fuels and can operate with a fleet of internal combustion engines. Using biofuels can decrease carbon dioxide emissions from internal combustion engine fleets. Typically, bioethanol production involves the microbial fermentation of fermentable carbohydrates into ethanol. Fermentation processes used in bioethanol production generally employ yeast (<em>Saccharomyces cerevisiae</em>) to convert sugars from biomass into ethanol and CO₂. Batch, fed-batch, and continuous fermentation techniques are used, with advances such as immobilized cell reactors and genetic engineering improving output and efficiency. Furthermore, combining enzymatic hydrolysis with fermentation (simultaneous saccharification and fermentation) enhances the conversion of complex carbohydrates to ethanol. Traditional feedstocks (first-generation feedstock) consist of cereal grains, sugar cane, and sugar beets. However, lignocellulosic (second-generation), microbial biomass (third-generation), and genetically modified microalgae (fourth-generation) based feedstocks have been researched due to concerns about the sustainability of food. This paper discusses available methods, such as fermentation techniques, and compares bioethanol generation from various feedstocks. The objectives of this review are to compare different generations of biofuel production. The current review also provides industrial producers with knowledge of the technologies and resources that are currently accessible and the possibilities for future innovation.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"57 ","pages":"Article 101634"},"PeriodicalIF":7.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review article provides an overview of recent literature on how electric vehicle batteries are aged during different charging strategies, such as conductive charging, inductive charging, and battery swapping. This study finds that some charging conditions, such as fast charging at low temperatures, degrade batteries faster. Battery ageing is a non-linear process and depends on, for example, temperature, charging current, and state-of-charge. The high charging rates strongly influence battery degradation. It is concluded that there is a trade-off between faster charging and a longer battery lifetime. There is an interest in vehicle-to-grid to add revenues and grid flexibility. However, the related battery degradation needs to be further investigated. A key challenge in the decision-making process is to plan for charging infrastructure suitable for electric vehicle owners while contributing to the long life of electric vehicle batteries and ensuring socially acceptable and economically viable solutions.

Conversely, renewable energy shows a negative correlation with CO2 emissions, as a 1 % increase in renewable energy use leads to a 0.32 % reduction in emissions. FDI was found to increase emissions, with a 1 % rise in FDI contributing to a 0.27 % increase in CO2 emissions, indicating a pollution haven effect.

Particularly, the humanizing energy may affect the complex links, e.g., synergy and trade-off, between the ET dimensions, e.g., energy equity, energy security, and environmental sustainability, influencing the policy pathfinding for balanced growth of ET. In this respect, the United Nations plan of action for 2030 especially goal seven, i.e., affordable and clean energy, associates with this purpose. Accordingly, this study addresses the dynamic multi-dimensional assessments to indicate how such agreement affects the complex links between the ET dimensions in the top 25 ET-performing countries, which are also recognized as leaders across the energy transition index. To do this, three analytical methods, e.g., the Markov switching regimes, spillover effects, and advanced sustainability analysis, are applied. The results show that complex links between the ET dimensions are time-varying and asymmetric pre- and post-the 2030 Agenda. Specifically, the Markov regime-switching analysis reveals that a dynamic combination of synergies and trade-offs can lead to a balanced growth of ET in response to the 2030 commitments under different regimes. Then, the spillover effects exhibit that the intensity and mode of synergy/trade-off throughout the short-term fluctuations of ET networks are affected by the 2030 commitments, which require supervising risk transmission management and regulations towards a balanced growth of ET. Last, the advanced sustainability analysis discloses causality between the ET dimensions through synergy, trade-off, or D-linking by different countries in response to the 2030 commitments. Consequently, combining these three applied methods serves actionable policy implications that can be instrumental in formulating strategies of humanizing energy towards a balanced growth of ET in top energy trilemma performers and potentially other analogous settings globally. These strategies should focus on connections between the “5 Ds”, e.g., decarbonization, digitalization, decentralization, disruption, and diversification, which navigate the uncertainties and complexities energy leaders face.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"57 ","pages":"Article 101623"},"PeriodicalIF":7.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
