Recently, some Lema\^itre-Tolman-Bondi metrics have been considered as models alternative to the dark energy within the Friedmann-Lema\^itre-Robertson-Walker universes. One of these models has been confronted with cosmic observations, this confrontation seeming to rule it out. On the other hand, we show that the \emph{intrinsic} energy of this model does not \emph{physically} vanish. Thus we conclude that this model is actually a non \emph{creatable} one. This suggests from the very beginning that the model is not a good model to represent our Universe, which would be in according with the negative result of this confrontation with observations.
