In this study, the driving forces of energy demand in Türkiye's manufacturing industry and their contribution to the decoupling between energy consumption and production increase are analysed via LMDI-I and the Tapio decoupling index between 2003 and 2014. It was seen that while the increase in production was the main driver of the rise in energy consumption, changes in the shares and energy intensities of sub-sectors also influenced energy consumption significantly. In that regard, despite the increase in most sub-sectoral shares, net structural impact contributed to reducing the energy demand. As for the intensity effect, it is seen that in most manufacturing industries, there were improvements at varying levels, and the final impact of these improvements on total energy demand was different for each sector. In this regard, the first six sectors in which changes in their sectoral shares and energy intensities had the most impact on total energy demand were found to be basic metals, chemicals and chemical products, textiles, other non-metallic mineral products, food, and rubber. Decoupling analyses showed that the fabricated metal products sector was the only sub-sector in which there was a strong decoupling. It was also found that decoupling occurred temporarily and was very limited in the manufacturing industry. However, in three years (2005, 2008 and 2013), there was a strong decoupling, with improvements in energy efficiency and changes in sectoral distribution being the main contributors.
