With the increase in awareness of environmental issues, companies and governments try to review their environmental policies. One of the most important policies for protecting the environment is the use of energy sources, which cause less or no harm to the environment. In this study, we examine the effect of institutional quality and the components of this institutional quality on green investments for G-20 countries. For this purpose, we employ static panel data analysis, as a main analysis, and dynamic panel data analysis as a robustness check. According to the main findings, institutional quality positively affects green investments and military spending reduces green investments. Also, robustness checks indicate that the effect of institutional quality and military expenditure of G20 countries on green investments is robust.

Inexhaustible energy sources are the focus of the energy industry for meeting the increased need for energy and reducing carbon emissions. Among various alternatives, harnessing solar energy has become a promising choice around the world. Parabolic trough collectors (PTCs) are an effective way to transform radiant energy into thermal energy, as well as electricity. However, these collectors can be improved by refining their design and tweaking the parameters related to thermal behavior. This may be done either by enhancing the surface area or improving the heat transfer coefficient of the heat carrying medium. These kinds of improvements could be achieved by making the use of nanofluids and by using inserts or fins within the collector tube. The current study provides an extensive review of PTCs from the points of view of their design, along with their thermal characteristics. Different types of nanofluids as the working liquid are investigated and discussed to achieve better PTC performance. Inserts within the collector tube and various design approaches, including fins, twisted tubes, U-shaped tubes, coiled wire inserts, and porous twisted tape inserts, are reviewed and discussed in detail. Finally, based on this review, challenges of PTC applications are described and future research recommendations are proposed.

Political competition is reflected in the strategic interaction of regional government's behavioral motivation driven by “official tournament.” Especially since environmental protection was officially included in the official performance appraisal system in 2005, the interactive trend of local governments’ economic development and environmental protection is more obvious. The policy uncertainty caused by this interaction is a major challenge for the government to promote regional sustainable development. Different from previous studies that only focus on the impact of political competition on environmental governance, this paper studies the impact of political competition on the low-carbon technology innovation from the perspective of sustainable development. Combined with the characteristics of Provincial Party Secretaries and Provincial Governors, the influence mechanism of political competition on low-carbon technology innovation is analyzed based on the method of spatial dubin model. Firstly, it finds that political competition has a significant negative impact on low-carbon technology innovation in the region and its adjacent regions, which is mainly caused by the political competition of Provincial Governors, while the political competition of Provincial Party Secretaries has no significant impact on low-carbon technology innovation. Secondly, the results of the mediation effect test show that reducing the intensity of environmental regulation in exchange for economic growth and political promotion opportunities is one of the reasons why the political competition of Provincial Governors inhibits low-carbon technology innovation. Thirdly, the results of the heterogeneity test of official characteristics show that the age of Provincial Governors is less and the tenure is longer, the stronger the inhibiting effect of Provincial Governors’ political competition on low-carbon technology innovation is. These conclusions provide policy suggestions for enterprises to make environmental investment decisions under different political environments.

The Paris climate agreement aims to achieve carbon neutrality by reducing carbon emissions all over the world. This can be accomplished by encouraging all stakeholders to switch to more carbon-free production methods, such as renewables, which cannot be achieved without high-level subsidies and financial aid. Therefore, the financial sector is inextricably linked to the renewable energy transition. The entire world is watching India, the world's second-largest importer of fossil fuels and the world's fourth-largest emitter of greenhouse gases. In this context, this work employs a financial development index in three dimensions: the overall financial development, the market-based financial development, and the bank-based financial development. We used the asymmetric nonlinear autoregressive distributed lags econometric model on data from 1980Q1 to 2020Q4 to investigate the effect of financial development on renewable energy consumption (REC) in India. As control variables, the model included real gross domestic product (GDP), trade openness, and oil prices. The empirical evidence shows that negative changes in overall and market-based financial developments (shocks) have a significant impact on REC. Changes in the development of bank-based finance have no immediate impact on REC. In the instantaneous and one-lagged periods, the later effect is both positive and negative. The asymmetric long-run effect of negative and positive changes (shocks) in all three dimensions of financial development has a significant impact on REC. As control variables, the model included real GDP, trade openness, and oil prices. Our empirical findings have significant policy implications.

To promote low-carbon development of the construction industry and popularize green buildings (GBs), considering the influence of marketing efforts and innovation capability on GB market demand, this paper constructs multiple incentive decision models based on contract theory, analyzes developers’ decision-making behaviors for incentivizing contractors’ green technology innovation (GTI) under different incentive decision models; and explores the impacts of greenness preference and service quality preference on contract prices, sales prices, innovation levels and marketing effort levels. In addition, the impacts of marketing effort cost coefficient and innovation capability on innovation levels, marketing effort levels and developers’ profits are simulated through parameter assignment and computer software. The results show that greenness preference and service quality preference have positive impacts on developers’ and contractors’ decisions and profits; under the decision model based on innovation level, the developers maximize profits, but the developers’ marketing effort levels and contractors’ innovation levels are lower at this time; under the decision model based on cost-sharing, the contractors have the highest innovation levels and achieve optimal profits, while the innovation capability can promote innovative activities. The results of the study have guiding significance for enhancing the levels of GTI and promoting the development of GBs.

This study looks at the impact of green economy activities on marine mineral conservation, emphasizing the critical significance of circular processes in building a sustainable blue economy. The research assesses the long-term viability of European blue economies using six indicators, including the value provided by the extraction of petroleum and natural gas and support activities for mining and quarrying projects. Municipal trash generation per capita and the amount of biowaste in recycling are used to determine circular effectiveness. According to the findings, a robust green economy performance is critical for increasing the sustainability of Europe's blue economy between 2012 and 2019. The link between the green and blue economies is nonlinear, with positive benefits shown when the green economy exceeds a particular threshold. Furthermore, the study validates these findings by investigating the impact of the green economy on ocean energy and marine minerals. These empirical findings have important significances for European authorities and policymakers aiming to effectively implement green programs in order to advance toward a sustainable blue economy and preserve marine mineral levels.

Removing backward production capacity and clearing out zombie enterprises is crucial to realize the carbon peaking and carbon neutrality goals. However, as a command-control environmental regulation policy, whether the New Environmental Protection Law (NEPL) can guide heavy-polluting enterprises to achieve green transformation and get rid of the zombified risk remains unknown. Our article applies the difference-in-difference (DID) method to explore the impact of the stricter environmental regulation policies on the de-zombification of heavily polluting enterprises in the context of the implementation of NEPL in China. The results show that the implementation of NEPL significantly reduces the zombified risk of heavy-polluting enterprises. The results were valid by a series of robustness tests of propensity score matching, common trends test, placebos test, conducting double clustered standard errors to industry and province level, eliminating other policy interference, ruling out reverse causation, easing the potential endogeneity problems, and controlling enterprise's internal management level. Furthermore, there is a time lag in NEPL policy, which requires a long-term mechanism. Moreover, the NEPL can promote enterprise de-zombie governance through the mechanism of market competition and market allocation. The effects of the NEPL are heterogeneous due to the nature of enterprise property rights, enterprise scale, industry radiation capacity, regional development level, and internal management capacity. This article provides policy implications for developing countries to promote de-zombified governance of their economic systems and defuse risks of green transition.

This article proposes the use of hybrid technique to achieve balanced and compromised solution among the generation cost and the emission of pollutants. Microgrids (MGs) are the restricted power energy system that transmitted, generated, and distributed. The renewable energy sources (RESs) are used in their fullest extent. Advantages of MG include reducing cost and transmission losses. Operated in different modes like wind turbine (WT), microturbine (MT) and fuel cell (FC). The proposed technique used to execute the golden jackal optimization (GJO) and Mexican Axolotl optimization (MAO) named as GJO–MAO technique. The objective of the technique is to solve dissimilar optimization issues in MG reduces the computational cost and maximize performance. The objectives of economic dispatch are based on fractional scheduling and restricted environment. Three different scenarios, low-voltage MG system are investigated. GJO–MAO techniques used to optimize various issues on MG by using renewable energy. The proposed technique performance is done in the MATLAB. When the time-of-use (TOU) energy market price strategy with the fixed pricing approach, the economic dispatch is calculated by time-of-use electricity market pricing method, generating cost decreases by 18.5%, 13.5% if the FP-related combined economic emission dispatch (CEED) is examined, and 15% after evaluating the environmental-constrained-economic-dispatch (ECED). The MG producing cost targets for ECED and ECD are according to renewable energy sources. The best and most system is used for finding a fair compromise between the cost of generating and emission. The smallest values of implementation time and standard deviation of superiority and robustness are achieved.

Rice husk is an abundant agricultural biomass and a potential source of amorphous silica and porous silicon. To produce high-purity SiO 2 and Si from rice husks, multiple steps of acid leaching to remove impurities and heat treatment to reduce residual carbon are necessary. In this study, a simple mechanochemical (magnesio-milling) experiment was conducted using an attrition mill to convert rice husk ash (RHA) and gasifier-derived rice husk ash (GRHA) into porous Si under various acid leaching (hydrochloric acid and lactic acid) and heat-treatment conditions. Three noteworthy results were obtained. First, eco-friendly lactic acid can be used instead of the harmful acid (hydrochloric acid). Next, the heat-treated GRHA was converted to Si via magnesio-milling without acid leaching. Finally, the carbon content (<0.3 wt%) of RHA and GRHA is a key factor affecting the conversion of SiO2 into Si based on elemental analysis. The purities of the Si samples prepared from RHA and GRHA, analyzed using inductively coupled plasma (ICP) mass spectrometry, were 97.66% and 95.62%, respectively. Furthermore, the porous Si prepared using RHA and GRHA can be utilized as a high value-add material such as an anode material for lithium-ion batteries and nanostructured materials.

Furthermore, the porous Si prepared using RHA and GRHA can be utilized as a high value-add material such as an anode material for lithium-ion batteries and nanostructured materials.","PeriodicalId":11652,"journal":{"name":"Energy & Environment","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135198312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
China is currently the world's largest new energy vehicle market, and the development of its new energy vehicles is crucial to the sustainable development of mankind. As a leader in the new energy vehicle industry, Tesla's entry into the Chinese market has an important impact on its new energy vehicle industry, and the study of the relationship between the two is of great significance in promoting the development of China's new energy vehicle industry. Therefore, we analyzed the complex relationship between Tesla and China's new energy vehicle industry from 2013 to 2022 based on the stock market perspective using modal decomposition, Maximum mutual information coefficient, and transfer entropy. Mutual information coefficient results show that Tesla has stronger co-movements with China's New Energy Vehicle Manufacturing sector, and its strength is highest in the medium- and long-term time scales, up to 0.196 and 0.529, respectively. whereas the transfer entropy results show that Tesla has a stronger information transfer effect on the Vehicle Manufacturing sector and Charging Pile sector than on the New Energy Vehicles Battery sector and New Energy Vehicles Parts sector. However, in general, Tesla's information overflow to the whole Chinese new energy vehicle industry is on the rise. The Chinese government can appropriately give Tesla certain favorable policies and encourage Chinese enterprises to cooperate with it, giving full play to Tesla's catfish effect and technology demonstration effect, and then promoting the further development of China's new energy vehicle industry.
