Abstract
Information and communication technology (ICT) has been ascribed a crucial role for raising resource and energy efficiency and thereby contributing to environmental abatement. We investigate this conjecture by providing evidence on the relationship between ICT and energy demand. Using a cross-country cross-industry panel data set covering 13 years, 10 OECD countries, and 27 industries, our results show that ICT is associated with a significant reduction in total energy demand. This relationship differs with regard to different types of energy. ICT is negatively related to the demand for non-electric energy, but is not associated with a significant change in the demand for electric energy. Quantitatively, the effect of ICT on energy demand is greater than that on labor demand. The results survive several robustness checks which allow for various forms of heterogeneity and tackle the potential endogeneity of ICT capital.
