Because of existing policy silos, energy policy tends to be addressed from a narrowly energy-centric basis; yet energy systems are clearly also affected by a wide range of policies emanating from other sectors. This article explores the impacts of policies associated with various ‘non-energy sectors’ on energy supply and demand, using a systematic and wide-ranging review of academic, policy and grey literatures. We discuss six policy sectors where these impacts are, in our assessment, not sufficiently recognised by policymakers or researchers but have significant energy implications. Overall, we find that there is little acknowledgement or analysis of this issue, especially of the full causal chain from ‘non-energy policies’ through to energy system impacts; for whatever reason, consideration of the reverse links (e.g. of the health impacts of energy policies) is far more common. The upshot is that non-energy policy impacts on energy systems are not sufficiently visible within either research or policy. We argue that this serves as a barrier to change, and that increasing the visibility of these complex and multi-faceted connections is thus a vital task for researchers and policymakers alike.
