Renewable energy holds a remarkable role in clean energy adaptation due to the much lower carbon footprint it releases compared to other fossil fuels. It also has a positive impact by slowing down the rate of climate change. The study has examined the links between renewable and non-renewable energy use, CO2 emissions and economic growth in developed, developing, and LDCs and Economies in Transition between 1990 and 2019 in 152 countries. Granger-causality has been used as the methodology to investigate the link between the variables. The findings of the existing studies on the relationship between the consumption of renewable and non-renewable energy sources and economic growth are inconsistent, indicating that there may or may not be a relationship between the two factors. Apart from having a few empirical studies so far have examined the link between the above-mentioned variables, analysis has yet to encompass all the regions in the four sub-groups discussed above. The results indicated that no Granger-causal relationship exists between GDP and REC outside of Economies in Transition. Additionally, the GDP and CO2 of all countries have a one-way relationship. Nevertheless, research indicates that GDP and CO2 have a bi-directional link in Economies in Transition, a uni-directional relationship in developing countries, and no meaningful association in developed and LDCs. Therefore, it is essential to emphasise actions to lower CO2 emissions and develop renewable energy while also stimulating the economy. Ultimately, more nations should choose renewable energy sources to build a more sustainable future.
可再生能源在清洁能源适应方面发挥着重要作用，因为与其他化石燃料相比，它释放的碳足迹要低得多。它还通过减缓气候变化的速度产生积极影响。本研究考察了 1990 年至 2019 年间，在 152 个国家中，发达、发展中和最不发达国家以及经济转型国家的可再生和不可再生能源使用、二氧化碳排放与经济增长之间的关系。采用格兰杰因果关系作为方法来研究变量之间的联系。现有研究关于可再生和不可再生能源消费与经济增长之间关系的结果不一致，这表明两者之间可能存在关系，也可能不存在关系。除了迄今为止已经有一些实证研究检验了上述变量之间的联系外，分析尚未涵盖上述四个子组中的所有地区。结果表明，经济转型国家以外的 GDP 和 REC 之间不存在 GDP 和 REC 之间的格兰杰因果关系。此外，所有国家的 GDP 和二氧化碳都存在单向关系。然而，研究表明，在经济转型国家中，GDP 和二氧化碳之间存在双向联系，在发展中国家存在单向关系，在发达国家和最不发达国家则没有有意义的关联。因此，必须强调采取行动降低二氧化碳排放和开发可再生能源，同时刺激经济。最终，更多的国家应该选择可再生能源来建设更可持续的未来。
