In this paper we explore the future of energy efficiency in Europe and its importance for the future energy demand. In particular, we look at the improvements in energy efficiency required to achieve our targets for energy consumption. We show that there are huge saving potentials available by the middle of the century (up to two thirds of primary energy demand, large enough to cover the 50% reduction target required in light of greenhouse gas reduction requirements. However, this will need specific policies to address the barriers energy efficiency faces. Indeed, energy efficiency policies need to be given a higher priority in the political and scientific agenda in Europe.enenergy efficiencyEuropepotential303600journal article
