Whenever I pedal the front wheel turns just as fast as the rear one. So from an energy standpoint it shouldn't make any difference since you need to supply enough energy to spin both wheels up to the same speed. But from the standpoint of how responsive the bike 'feels' a lighter front wheel can have a greater impact especially when you're in a sprint and moving the bike from side to side and also making steering adjustments.
