The renewable energy, CO2 emissions, and economic growth: VAR model

This paper provides an empirical analysis of CO2 emissions and economic growth, renewable energy consumption, and energy consumption over the period 1975-2014 in Germany. This paper uses the autoregressive distributed lag (ARDL) approach of cointegration test and vector error-correction models. The unit root and cointegration tests show that the long-run relationship between CO2 emissions and its determinants. The empirical results show that the findings do not support the environmental Kuznets curve between real GDP and CO2 emissions. To estimate the shocks of renewable energy consumptions, the study applies the dynamic test of Impulse Response Function (IRF) under the VAR method. The increasing portion of renewable energy consumption in electricity generation would have no impacts on the environment. However, the hikes of renewable energy sources would incur more cost to electricity producers and shrivel up the growth of economies through the expansionary effect of industry's consumption and private capital spending in the Germany's economy.
