This paper investigates the long-run and causal relationship between electricity consumption and economic growth in Turkey by using the ARDL cointegration test and Granger causality models. It employs annual data covering the period of 1977-2006. The ARDL cointegration test yields evidence of a long-run relationship between electricity consumption per capita and real GDP per capita. The results from the Granger causality models indicate that there is an evidence of unidirectional causality running from the electricity consumption to economic growth in the long-run. The overall results confirm the "Growth hypothesis" for Turkey. This implies that, energy conservation policies, such as rationing electricity consumption, are likely to have an adverse effect on real GDP of Turkey. †
