Current world environmental challenges put pressure on clean energy produced mostly through renewables. There is an undeniably important role of rare earth minerals in renewable energy technologies. This study aims to infer the relationship between rare earth clean energy renewable energy technologies and carbon emissions focusing on daily stock price index data and applying the novel quantile time-frequency connectedness model and the cross-quantilogram dependence approach during 2012-2022. Results show that spillovers among rare earth minerals and renewable energy are dependent on market conditions time horizons and analyzed quan-tiles. They also highlight the net receiver role of rare earth especially in the short term. Findings might help investors understand diversification benefits and support policymakers in developing strategies for lessening import dependence on rare earth metals as important as they are for renewable technology adoption to ensure green growth.

Although a few studies have analyzed the nexus of renewable energy and green finance the literature lacks the use of renewable energy by sources. The other major failure is that it uses only annual and small data. Therefore this study investigates the connectedness and spillovers relationship between green finance and five types of renewable energy (biofuels fuel cell geothermal solar and wind) by applying the novel TVP-VAR method of Balcilar et al. [1] to the daily indexes from July 31 2014 to Feb 4 2022. The results show that dynamic connectedness both total and pairwise is heterogeneous over time and influenced by economic events. Furthermore wind is found to be the largest transmitter of shocks to green finance followed by biofuels while both fuel cell and geothermal receive the least shocks. The findings suggest that green finance is mostly a net receiver of shocks from renewable energy sources and that wind has been a net receiver of shocks during the COVID-19 pandemic. A high interconnectedness between the indexes highlights the safe-haven property for diversification purposes of green finance. Our results are important for energy policymakers those responsible for the implementation of environmental policies individual investors and portfolio managers while also shedding light on the achievement of COP26 goals.
