  We present PHENIX recent results on charged particle and transverse energy
densities measured at mid-rapidity in Au-Au collisions at
$\sqrt{s_{_{NN}}}$=130 GeV and 200 GeV over broad range of centralities. The
mean transverse energy per charged particle is derived. The first PHENIX
measurements at $\sqrt{s_{_{NN}}}$=19.6 GeV are also presented. A comparison
with calculations from various theoretical models is performed.
