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.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998317","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}

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.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999618","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}

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.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999504","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}

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.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141001313","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}

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.","PeriodicalId":38194,"journal":{"name":"International Journal of Energy Economics and Policy","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998747","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}

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.","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}
