A structural VAR analysis of renewable energy consumption, real GDP and CO2 emissions: Evidence from India

This study has attempted to analyze the dynamics of renewable energy consumption, economic growth, and CO2 emissions. For the analysis, we used structural VAR approach. Results of unit root tests show that all variables are non-stationary at their level form and stationary in first difference form and cointegration analysis, analyzed through Johansen-Juselius (1990), shows that there is no evidence of cointegration among the test variables. The innovations analysis of study reveals that a positive shock on the consumption of renewable energy source increases GDP and decreases CO2 emissions and a positive shock on GDP have a very high positive impact on the CO2 emissions. The variance decomposition shows the share of consumption of renewable energy source explained a significant part of the forecast error variance of GDP and a relatively smaller or negligible part of the forecast error variance of CO2 emissions.
