Nowadays, developments in production technology enable energy to be used more efficiently than before. The more efficient use of energy makes energy saving possible and causes the economic phenomenon called rebound effect in the literature. The purpose of this study is to investigate whether rebound effect is valid in OECD countries in the period 1995-2015. For the purpose of the study, panel cointegration analysis was conducted for the relationship between energy use, primary energy density, Gross Domestic Product and urban population variables. As a result of the analysis, the increase in primary energy density increases energy use; economic growth leads to an increase in energy use; It has been determined that increasing urbanization rates reduce energy use. The results showed that the increases in energy density for OECD countries in the period 1995-2015 increased energy use by reducing energy efficiency. In this context, it is concluded that the rebound effect, which explains the positive trend created by the price mechanism in the market due to the increase in energy efficiency due to the decrease in energy intensity, is not valid.
