Where does energy go in destructive interference?

I read about Young's double slit experiment. I find one thing difficult to comprehend.; What happens to the energy associated with the waves when two identical waves perfectly cance out each other? Typical answer i have obtained is : The energy just gets transfered to the point of constructive interference from the point of destructive interference. I have trouble in grasping this idea of " redistribution of energy." Please help.

Think about it this way. If constructive interference means there is more energy, where did that energy come from? The energy that is no longer in a node for destructive interference is going into the anti-node of the constructive interference. This page describes it very well.
