This study aims to determine the energy efficiency of three-phase induction motors (TIM) powered when operated with photovoltaic systems (PVS). The environmental advantages of photovoltaic systems (PVS) are very well known. However, there are still challenges related to energy quality, electricity generation instability, failure in frequency regulation, instability in reactive power, and harmonics generation. However, the impact of PVS on TIM efficiency has not been thoroughly explored. This research compares a TIM's electromechanical characteristics and efficiency when powered by a conventional electrical grid versus a PVS. Experimental studies revealed that when powered by the PVS, the TIM experienced increased voltage and higher voltage and current harmonics compared to grid power. These electrical difficulties, attributed to the PVS inverter, resulted in a 2.7% decrease in TIM efficiency compared to grid power. Modeling conducted under actual load variation conditions demonstrated a 2.6% increase in energy consumption when powered by the PVS compared to grid power. Based on these findings, PVS installers are advised to consider the energy quality provided by these systems, as it may affect the efficient operation of TIM, leading to increased energy consumption.
本研究旨在确定使用光伏系统(PVS)供电的三相感应电动机(TIM)的能效。光伏系统(PVS)的环保优势众所周知。然而,在能源质量、发电不稳定性、频率调节故障、无功功率不稳定性和谐波产生等方面仍存在挑战。然而,光伏系统对 TIM 效率的影响尚未得到深入探讨。本研究比较了由传统电网和光伏系统供电时 TIM 的机电特性和效率。实验研究表明,与电网供电相比,光伏系统供电时,TIM 的电压升高,电压和电流谐波增大。由于 PVS 逆变器造成的这些电气困难,导致 TIM 效率比电网功率降低了 2.7%。在实际负载变化条件下进行的建模显示,与电网供电相比,由 PVS 供电时的能耗增加了 2.6%。基于这些发现,建议光伏系统安装人员考虑这些系统提供的能源质量,因为它可能会影响 TIM 的高效运行,导致能耗增加。

The main aim of this article is to comprehend the long-run relationship among sea transportation, energy use, GDP, and CO2 for USA from 1980 to 2023. In this sense, FMOLS, DOLS, CCR, and ARDL analyses are employed in order to investigate the entity of long-run linkage between the relevant variables. According to results of this manuscript, except energy use there is no both long-run relationship among variables and effects of independent variables (GDP, sea transportation) on dependent variable (CO2 emissions) from 1980 to 2023 in USA. Therefore, the sea transport-induced EKC hypothesis has not been confirmed empirically. Although the hypothesis has not been confirmed, there are some issues to consider in terms of energy consumption. Transportation energy consumption and greenhouse gas emissions are seen as an alarming threat to leaving a livable and sustainable green environment and economy to future generations. Fossil fuels used in transportation have an important place in carbon dioxide emissions. This is seen as a crucial environmental factor that all stakeholders should consider when planning energy and environmental policy decisions. In order to prevent environmental quality from being negatively affected by greenhouse gas and exhaust emissions, policy makers need to encourage more energy efficient and healthier transportation ways. Thus, the harmful effects of transportation energy consumption can be reduced as well.

Women can play an active role in determining environmental quality, and Saudi women’s share in the labor market is increasing considerably. Women's participation is still low in the labor market, and their participation might affect the aggregated environmental situation. Therefore, we explore the effect of Women's Labor Participation (WLP) on CO2 emissions in Saudi Arabia from 1990 to 2022 by employing a cointegration technique. The Environmental Kuznets Curve (EKC) is tested and substantiated in the long run, but it is not verified in the short run. WLP raises CO2 emissions. Thus, women's labor market entry has environmental consequences. Moreover, trade openness also contributes to CO2 emissions over a long period of time. Nevertheless, its short-term impact is environmentally pleasant. The study recommends checking environmental problems out of WLP by developing gender-responsive environmental policies. So, gender equality and sustainable growth would be targeted simultaneously.

Sustainable agricultural development is essential for ensuring food security, economic growth and ecological balance, which is a challenging phenomenon to achieve. This phenomenon is studied in the case of BRICS, considering agricultural value added, economic growth, openness to trade, carbon dioxide emission and net foreign direct investment. Panel unit root test, Fixed and Random Effect Model, Panel Cointegration test and Panel Causality are studied. Results of the analysis indicate that in all the BRICS countries, agricultural value added is significant to economic growth, inward foreign direct investment is reduced with agricultural growth, and inward foreign direct investment causes trade openness.

This study explores how global airlines can achieve growth and environmental conservation using transport, financial performance, and carbon dioxide (CO₂) emissions data before, during, and after the COVID-19 pandemic from 2019 to 2022 with manually collected data for 38 leading international airlines. First, the regression analyses identify a clear range of turning points that airlines should consider in terms of Scopes 1 and 2 CO₂ emissions per employee and cargo ton-kilometers per employee (cargo ton-kilometers (CTK)/EMP) considering the environmental Kuznets Curve (EKC) hypothesis. Second, the deciding factors, including fundamental efforts by the airlines themselves, result from the interaction of three points, which have been encouraged and promoted in the airline industry in recent years. (1) Tighter emissions controls for air transport, (2) investors’ emphasis on environment, society, and governance (ESG), and (3) assessments and guidelines from ratings agencies and economic and environmental organizations. Third, increasing CTK/EMP to verified thresholds and taking an ESG-oriented approach can contribute to airlines’ combined achievement of growth and environmental conservation and related data will expand academic and policy-related research.

Climate change is an issue that is of concern to the global public and scientific community. There is a close relationship between climate change and carbon emissions, which are the primary cause of global warming. Reporting on carbon emissions is essential for corporate accountability to stakeholders when evaluating a company's financial and non-financial performance. Good management of carbon emissions will enhance the company's reputation. This study analyses the impact of company profitability and market value on the disclosure of carbon emissions, with environmental performance serving as a moderating variable in the context of Indonesian public companies. This study concludes that: (1) There is no significant impact on profitability, as measured by Return on Assets, on Carbon Emission Disclosure; (2) The study finds that there is a statistically significant positive relationship between market value, measured by Tobin's Q, and the level of carbon emission disclosure. This relationship is significant at a 5% significance level; (3) The moderating effect of environmental performance on the relationship between profitability, as measured by return on assets, and carbon emission disclosure is found to be insignificant; (4) The significance level of 10% indicates that the relationship between environmental performance, as a measure of a company's environmental practices, and market value, as represented by Tobin's Q, is strengthened concerning the disclosure of carbon emissions. This research can contribute to developing accounting knowledge to close gaps in the body of knowledge regarding the disclosure of carbon emissions in developing nations, particularly Indonesia.

This research aims to identify the relationship between non-renewable electricity (NRE), renewable electricity (RE) and government expenditures (EXPD) on environmental degradation using the ARDL model for 10 Newly Industrialized Countries (NIC) during the period 1990-2021. Our empirical findings show that the NRE increases the CO2 emissions, however the RE decrease the CO2 emissions in the long and short run. For the effect of governement expenditure on the environment, it may be classified as direct and indirect. In fact, EXPD affect positively the CO2 emissions. In contrast, The indirect effect operates through the interaction between EXPD and NRE and RE. Our results demonstrate that the interaction between EXPD and NRE affects negatively the CO2 emissions. Nevertheless, the impact of the interaction between EXPD and RE on the CO2 emissions is more important. The results show also there is a bidirectional causality between each variable and CO2 emissions. With the empirical findings as a basis, we suggest that the NI countries should reduce NRE consumption and enhance the environmental expenditures so that they may produce more RE to combat environmental issues.
本研究旨在利用 ARDL 模型,识别 1990-2021 年间 10 个新兴工业化国家的不可再生能源电力(NRE)、可再生能源电力(RE)和政府环境退化支出(EXPD)之间的关系。我们的实证研究结果表明,从长期和短期来看,新能源会增加二氧化碳排放量,而可再生能源则会减少二氧化碳排放量。政府支出对环境的影响可分为直接和间接影响。事实上,预算外支出会对二氧化碳排放产生积极影响。而间接影响则是通过预算外支出与 NRE 和 RE 之间的相互作用产生的。我们的结果表明,EXPD 和 NRE 之间的交互作用对二氧化碳排放有负面影响。然而,EXPD 和 RE 之间的相互作用对二氧化碳排放的影响更为重要。结果还显示,每个变量与二氧化碳排放量之间都存在双向因果关系。在实证研究结果的基础上,我们建议北欧国家减少净可再生能源消费,增加环保支出,从而生产更多的可再生能源来应对环境问题。

Currently, the generation of CO2 emissions into the environment has increased due to the use of fossil fuels by the transportation sector and other economic sectors, motivating governments to propose mitigation actions. As a result, the search for zero-emission transportation alternatives has gained momentum, with Hydrogen technology being one of the promising solutions due to its clean and efficient energy source. In compliance with this, the Hydrogen roadmap was developed in Colombia, which seeks to encourage the use of hydrogen as a fuel and energy generator in the country. In this study, the current composition of the vehicle fleet was characterized, then a dynamic simulation model was constructed for the replacement of fossil fuel vehicles with zero-emission vehicles, considering the particularities of the country, to finally analyze the generation of CO2 in the vehicle fleet from different scenarios related to the policies proposed by the government of Colombia and stipulated in the roadmap of hydrogen. With this, it was possible to demonstrate the positive impact of taking measures for vehicle replacement in the long term. Additionally, the model could be employed in other countries, considering the particularities of the vehicle fleet and the regulations specific to the regions.

Additionally, the model could be employed in other countries, considering the particularities of the vehicle fleet and the regulations specific to the regions.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
