This paper examines the issues associated with the causal relationships between the energy consumption and the factors ( rural population, total population, gross domestic product, consumer price index and carbon dioxide emission), with the greatest impact on energy consumption as demonstrated in the literature, for 30 developing countries. Data for the period 1971-2007 are used with a Granger causality test. In the light of obtained findings, the present study reveals common relationships in various directions between energy consumption and the other factors. These results can be explained by factors such as energy markets, resources, population etc. for individual countries. The findings of the study have significant policy implications and are therefore of potential interest to policymakers.
