Abstract Plain Text: 
The ALICE experiment has measured the transverse energy at mid-rapidity in PbPb collisions as a function of centrality at LHC energies. 
We discuss studies of the transverse energy in PbPb collisions at  sqrt(sNN) = 2.76 TeV, and compare the results with theoretical models as well
as to data obtained at lower energies. We find a similar centrality dependence shape for mean of dEt/deta as was seen at
lower energies at RHIC, and a growth in mean dEt/deta  to LHC energies with sqrt(sNN).
These measurement place additional constraints on models that were successful in describing mean dEt/deta for LHC energies.
