Keywords: GDP, causality, Electricity Consumption, Energy consumption

This study investigated the nature or direction of causality between GDP, electricity consumption and total energy consumption in the OECD. Secondary data was used while both the ordinary least square (OLS) and generalized method of moments (GMM) estimators were employed to test for causality in our model. Our result found the presence of a bi-directional causality between energy consumption and GDP for the total energy demand model and between electricity consumption and GDP for the electricity demand model. By implication, the bi-directional causality in our estimated models suggest that both energy consumption and GDP are important factors in economic development in the OECD. Thus, if misguided policy measures are made to reduce energy consumption it could have a detrimental effect on GDP which will slow down economic growth. A recommendation is for policy makers to concentrate on encouraging energy efficiency as a way to reduce energy and electricity consumption.
