Asymmetric linkages between wind energy and ecological sustainability: Evidence from quantile estimation

Renewable energy is gaining popularity since it is cheaper and more efficient than conventional energy sources. New green energy technologies, like wind energy, are primarily utilized to maintain ecological sustainability. This study looked at the asymmetric link between wind energy and ecological footprint in the top-10 wind energy-consumer economies (China, USA, India, UK, Germany, Spain, France, Canada, Brazil, and Italy) by using the data from the years 1991-2020. Most past research utilizes panel data techniques, which yield common findings on the wind energy-environment nexus, despite the reality that some nations have no evidence of such association on their own. This research, on the other side, employs a novel approach "Quantile-onQuantile", which can explore time-series interdependence in each economy separately to gain worldwide yet economy-related evidence for the linkage between the variables. The results imply that wind energy consumption minimizes ecological footprint at distinct quantiles in sample nations, with the exception of Spain and India, which show mixed findings. However, the degree of the asymmetric association of the variables varies by country, necessitating individual vigilance and caution on the behalf of governments when designing wind energy and ecological sustainability policies.
