Climate change and environmental degradation are critical global challenges, and the G-20 nations play a pivotal role in addressing these issues due to their substantial contributions to global GDP and carbon emissions. Transitioning toward renewable energy sources is imperative for mitigating CO2 emissions and achieving sustainable development. This study investigates the impact of technological innovation, gross domestic product (GDP), renewable energy consumption, economic freedom, and financial advancement on renewable energy use and environmental pollution levels in G-20 countries from 1995 to 2022. Utilizing the PMG-ARDL dynamic panel method, the research analyzes both long-term and short-term relationships among the variables. The findings reveal that technological innovation significantly boosts renewable energy adoption, with a 1% increase in technological innovation leading to a 0.33% rise in renewable energy use in the long run and a 0.17% increase in the short run. Additionally, increased renewable energy consumption is strongly associated with reductions in CO2 emissions, highlighting its critical role in promoting environmental sustainability. The study emphasizes the importance of policies designed to enhance technological innovation to foster renewable energy usage and reduce environmental pollution. It recommends expanding and reforming the technological sector to align international and local resources with renewable energy initiatives, providing a workable framework for supporting the green growth of institutions and achieving a more sustainable future for G-20 nations. This research contributes to understanding the intricate dynamics of renewable energy transitions, offering actionable insights for policymakers and stakeholders in addressing global environmental challenges.
气候变化和环境退化是全球面临的重大挑战,二十国集团(G-20)国家因其对全球GDP和碳排放的巨大贡献,在应对这些问题方面发挥着关键作用。向可再生能源转型对于减少二氧化碳排放和实现可持续发展至关重要。本研究考察了1995年至2022年期间技术创新、国内生产总值(GDP)、可再生能源消费、经济自由度和金融发展对G-20国家可再生能源使用和环境污染水平的影响。该研究采用PMG-ARDL动态面板方法,分析了各变量之间的长期和短期关系。研究结果表明,技术创新显著推动了可再生能源的采用,从长期来看,技术创新每提高1%,可再生能源使用量将增加0.33%,短期内增加0.17%。此外,可再生能源消费的增加与二氧化碳排放量的减少密切相关,凸显了其在促进环境可持续性方面的关键作用。该研究强调了旨在加强技术创新以促进可再生能源使用和减少环境污染的政策的重要性。它建议扩大和改革技术部门,使国际和本地资源与可再生能源倡议保持一致,为支持机构的绿色增长和为G-20国家实现更可持续的未来提供一个可行的框架。这项研究有助于理解可再生能源转型的复杂动态,为政策制定者和利益相关者应对全球环境挑战提供可操作的见解。
