Dynamics of renewable energy index in G20 countries: influence of green financing.

Abstract

The research intends to investigate the green financing trends movement with renewable energy dependence of G-20 economies. The data envelopment analysis (DEA) technique explains research results and illustrates current topicality. The Wald econometric method is utilized for robustness analysis, and a comparative picture of public support is provided. The research demonstrated that green financing metrics are significantly affected by public support during the COVID-19 crisis. Due to the volatility of COVID-19, public assistance funding plays an uneven role in green finance. G-20 member nations financed 17% of total green financing using public funds, which contributed 4% to GDP and achieved 16% of annual energy dependence improvement due to COVID-19 and 24% additional production from renewable energy resources. The results of this research demand maximal support by using positions in the government, ministries in charge of energy efficiency, and departments for energy efficiency improvement. Several possible policy interventions are discussed in this paper that may increase renewable energy efficiency via several alternative approaches, including on-bill financing, direct efficiency grant, guaranteed energy efficiency contracts, and credit lines for energy efficiency. If recommended policies are implemented successfully, they are expected to reduce the crisis' impact and elevate funding for energy efficiency.
