We show that the distribution of observed energies of GRB with known redshifts can be explained by the hypothesis of the standard energy release ergs. Two situations are possible, either the beaming angle differs from burst to burst, or there is a universal emssion diagram in each burst, the observed difference being due to different viewing angles.
