A barrier created out of any sort of energy, including [[magic|magical]] and [[psychic]] energy.  Frequently the energy produces a [[transparent]] wall, screen, or bubble, but may also be used for creating things such as surfaces for walking on.  Energy barriers are a common feature in [[science fiction]] and [[fantasy]].

Energy barriers are most frequently used to defend against attacks, but may also serve as screens restricting passage, prisons for entrapping a target, or even an attack by pushing the field of energy outward into nearby targets.
