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. © 2022 Elsevier B.V.
