Why is access to energy important for future economic growth? The relationship between energy consumption and Economic growth is a well-studied topic in energy economics. By using a standard (such as GDP) it is possible to compare the growth between countries s and find amore comprehensive results to the relationship between the two. The results of the unit root tests for levels and first differences suggest that in all countries, EC and GDP appear to be Stock and Watson sensitive variables. Among the top 10 emerging economies, only in the case of Indonesia, the test indicates non-existence of a unit root in levels when we assume trend and intercept in the series. However, the test statistics are vague and the trend term did not appear significant. We make similar assumptions for GDP in UK and Germany and for EC in Italy. Therefore, we conclude that EC and GDP are Stock and Watson sensitive in all 16 countries. Where the error correction term (ECT) represents the error terms derived from the long run co-integrating relationship. The error-correction representation allows for causality to show through two possibilities. First, testing the joint significance of the coefficients (?11i) of the independent variable can check for short run causality. The joint significance of ‘?11i {draw:frame} indicates that the dependent variable is responding to short-term shocks to the environment. Secondly, the long run causality can be tested by looking at the significance of the speed of adjustment (?), which is the coefficient of the error correction term. The significance of ‘?’ indicates that the long run equilibrium relationship is directly driving the dependent variable. In addition to the extra way for causality to emerge, the VEC offers another benefit that the ...
