The short-run and long-run relationship between energy consumption variables and economic growth are estimated by using the newly developed autoregressive distributed lag (ARDL) approach to cointegration analysis. The results indicate a long-run relationship between economic growth and energy consumption variables. Although, the coefficient of coal consumption is positive but is statistically insignificant, while both petroleum consumption and electricity consumption have positive and are statistically significant on economic growth. Moreover, the coefficient of error correction model suggests that the speed of adjustment in the estimated model is relatively high and had the expected significant and negative sign.The study therefore recommends that government should strengthening the ongoing transformation agenda particularly on energy infrastructure to create sufficient energy supply. This can be done through service availability, affordability, and accessibility.

The results suggest that there is a long-run relationship between health expenditure and economic growth, indicating that there is causality relationship in at least one direction. However, it does not indicate the direction of causality. Therefore, the Granger causality test indicates a strong bidirectional relationship between health expenditure and economic growth. It is therefore important for the Nigerian government to include investment in health as a tool of macroeconomic policy, due to the fact that differences in economic growth rates between countries have been significantly explained by health differences, showing that investment in health improves economic growth.
