Abstract

This study delves into the intricate relationships among external debt, remittances, political stability, urbanization, and renewable energy consumption in the context of BIMSTEC nations for 1995-2021. Motivated by the growing significance of sustainable energy practices and the need for informed policy decisions. This research employs a comprehensive methodology, including recently introduced Cross-sectional dependency, Slope of heterogeneity test, error correction-based cointegration test, Dynamic Common Correlated Effects (DCE), and instrumental variable-adjusted DCE method. While external debt shows a positive association with renewable energy consumption, careful consideration is required, as indicated by the nuanced impact of the DCE and Instrumental Variable (DCE-IV) models. Remittances exhibit a positive nexus with renewable energy consumption, emphasizing the role of household purchasing power. Urbanization, reflecting a positive correlation with unemployment rates, surprisingly points towards an increased demand for renewable energy, highlighting the need for strategic planning. Political stability, trade openness, and foreign direct investment (FDI) also demonstrate varying impacts on renewable energy consumption. The findings underscore the intricate nature of these relationships, urging policymakers to adopt tailored approaches. Consequently, this study contributes valuable policy insights for BIMSTEC nations, emphasizing the importance of sustainable energy strategies aligned with economic and social dynamics.

Abstract

Energy poverty remains a critical developmental challenge in Least Developed Countries (LDCs). However, existing literature tends to examine renewable energy, technological innovation, and carbon emissions separately, often overlooking their interconnected impact on energy poverty. Addressing this significant research gap, the present study investigates the combined roles of renewable energy consumption (REC), technological innovation (TI), and CO₂ emissions in alleviating energy poverty in LDCs from 2000 to 2020. Specifically, the study explores: (1) how renewable energy consumption influences energy poverty reduction; (2) the extent to which technological innovation improves energy accessibility and affordability; and (3) the impact of carbon emissions on pathways to reducing energy poverty. Utilizing advanced econometric methods on an extensive panel dataset, the findings reveal that a 10% increase in REC reduces energy poverty by approximately 0.814% to 1.105%, underscoring renewable energy’s vital role in providing sustainable and affordable energy access. Similarly, technological innovation significantly mitigates energy poverty; a 10% improvement in TI results in a 1.215% to 1.564% decrease in energy deprivation, highlighting innovation’s potential to overcome infrastructural barriers in energy delivery. Furthermore, a 10% reduction in CO₂ emissions correlates with a 0.914% to 1.399% decline in energy poverty, reinforcing that low-carbon strategies effectively promote both environmental sustainability and equitable energy access. This study uniquely integrates these factors, offering novel empirical insights into their collective influence on energy poverty in low-income contexts—an area previously underexplored. The findings emphasize the urgent need for coordinated policy frameworks and targeted investments in renewable energy infrastructure and technological innovation. Such integrated strategies are essential to simultaneously address energy poverty and environmental challenges, fostering sustainable, low-carbon growth trajectories aligned with the global Sustainable Development Goals (SDGs).

Abstract

This study investigates the relationship between economic freedom, trade freedom, digitalization, and innovation on renewable energy consumption among G20 nations over the period 2000–2023. Utilizing a robust empirical framework—including Dynamic Common Correlated Effects (DCCE), Instrumental Variable-adjusted DCCE (DCCE-IV), and Dynamic Seemingly Unrelated Regression (DSUR)—the analysis reveals nuanced insights into how these economic and technological dimensions shape the transition toward sustainable energy systems. Results demonstrate that a 10% rise in economic freedom correlates with a 1.112%–1.688% increase in renewable energy consumption, while trade freedom yields a positive impact ranging from 0.904% to 1.182%. Technological innovation contributes between 0.915% and 1.571%, and environmental innovation exerts an even stronger effect, ranging from 1.273% to 1.616%. Interestingly, despite the energy intensity associated with digital technologies, digitalization also supports renewable energy adoption, showing a positive influence between 1.013% and 1.526%. These findings underscore innovation's pivotal role in mediating the effects of economic policy and digital transformation on renewable energy usage. The study advocates for integrated policy approaches that simultaneously promote market liberalization, digital infrastructure, and innovation investment. This would accelerate the transition to renewable energy and help G20 nations meet Sustainable Development Goal 7 (affordable, reliable, sustainable, and modern energy for all). The results emphasize the need for synergistic strategies that connect economic openness, technological advancement, and environmental priorities, offering a roadmap for policymakers seeking to enhance clean energy deployment in large, high-impact economies.
