The cartel is set to cut 1 million barrels of production but that may actually force prices lower in the long run. But it could also undermine prices in the long run, energy experts said, by encouraging more conservation and investment in alternative energy. Furthermore, the cut by OPEC could actually come back and haunt the cartel later since it gives the world more of a cushion against further output disruptions in the future. Initially, news of the planned cut last week sent prices rising back above $60 a barrel. But prices have fallen back since then, to about $58 Wednesday, as OPEC ministers bicker over exactly which nations should cut how much, and when they will do it.
