Some countries on the continent are officially leading the way in achieving SDG7, thanks to this type of energy. As of 2020, some African nations had a relatively high proportion of renewable energy (RE) in their primary energy supply, contributing to their enhanced energy self-sufficiency. In this study, 15 low- and lower-middle-income African countries are selected, and the elements that statistically significantly affect high shares of RE supply from 2000 to 2022 are scrutinized. For this purpose, second-generation panel data methods, CS-ARDL, are used to assess the effects of sustainability, economic growth, and energy equity indicators on the share of renewables in primary energy supply. The study shows that in the short term, RE supply is significantly but adversely affected by the total primary energy use. Energy intensity and access to renewable fuels contribute to an increased supply of RE. Moreover, RE supply experiences a strong and favourable influence from both economic expansion and lower interest rates. This study contributes to the body of knowledge on renewable-based energy systems in African countries by underlining the impact of interest rates and other factors that influence RE share in the entire primary energy supply, going beyond the power sector. The findings could serve as an evidence base for decision-makers in drafting evidence-based investment, sustainable development, and development assistance strategies.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"97 ","pages":"Article 102068"},"PeriodicalIF":4.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is influenced by various determinants, including the inputs of its operational facilities and numerous urban economic and social development factors. In addition, urban transport infrastructure encompasses multiple categories of transportation modes, and their environmental performances may differ; however, they are typically influenced by similar factors. Therefore, it is necessary to use a scientific method to analyze their determinants jointly. This paper examines the environmental performance of different categories of urban transport infrastructure and their determinants, taking six megacities in China as examples. Their EPUTIs are evaluated by the entropy method. The seemingly unrelated regression models are employed to analyze the determinants of the environmental performance across different categories of urban transport infrastructure. The results display that 1) the improvement of environmental performance of urban bus was not significantly relied on the increase of its operational vehicles; 2) the improvement of environmental performance of urban rail transit was mainly relied on the enlargement of scales of their operational vehicles and environmental performance of urban road was significantly negatively affected by the scale of civilian car ownership; 3) urban economic and population scales were still the important determinants of environmental performance of urban transport infrastructure; 4) the investment intensity of urban transport infrastructure and urban technological level have weaker impacts on environmental performance of urban transport infrastructure.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"97 ","pages":"Article 102037"},"PeriodicalIF":4.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
