Hydropower renewable energy is known to be pro-environment: flexible and affordable. Above all, it is compatible with other energy frames and also with the policies that otherwise prove to be inimical towards its future. Where environmental stability is concerned it needs an assiduous study coupled with research by the policymakers to get around knowing the different perspectives of hydropower renewable energy. The study has taken nine different and diverse perspectives of hydropower renewable energy into account to stop the process of environmental degradation. EKC framework has been put to use in a case study of South and East Asia economies. Time period has been selected from 1975 to 2020 to measure the long-term impact. GMM model has been used for the panel estimation besides getting future dynamics. The results which have come about confirmed EKC in the selected countries. Non-renewable energy (coal and gas) had an adverse impact on environmental stability. However, switching towards hydropower renewable energy can mitigate these environmental losses. Empirical findings have proved that more use of clean energy production can bring about a considerable amount of environmental stability. Insofar as East Asia economies are considered they have reached the second stage of EKC with a turning point of $13844 (per capita income). This paper, therefore, suggests that the future depends upon renewable hydropower energies in South and East Asia economies. That being said, there appears to be a dire need to undertake the role of various socioeconomic and geographic factors that influence hydropower renewable energies to check the long-term effect.

This study uses a comparative approach for comparing the nexus of economic growth, renewable and nonrenewable energy consumption, urbanization, trade, and CO2 emissions for South and East Asian countries from 2000 to 2018. The short- and long-run connections between the variables are explored using the dynamic common correlated effects (DCCE) CS-ARDL approach, and the causal linkages are assessed using the Dumitrescu-Hurlin (DH) panel causality test. The data show that the factors have long-term relationships. The findings show that nonrenewable energy consumption and economic growth increase long-term CO2 emissions in South Asia, but trade and use of renewable energy consumption reduce CO2 emissions in the short term. Long-term causal relationships between CO2 emissions, renewable energy use, economic growth, and trade are also revealed by the South Asian causality test. In East Asia, economic growth, NREC, trade, and urbanization increased CO2 emissions in the short and long run, while REC appears to reduce CO2 emissions. According to the causality analysis, long-run bidirectional causation exists between CO2 emissions, renewable energy use, economic growth, and trade. Furthermore, policy suggestions may be made, such as using renewable energy sources to lessen CO2 emissions and improving education and corruption to forecast economic growth in the examined areas.
