The mean kinetic energy of the conduction electrons in metals is ordinarily much higher than kT because (1) electrons have many nore degrees of freedom than atoms d0 (2) the electrons and the lattice are not in thermal equilibrium (3) the electrons form a degenerate Fermi gas 4) electrons in metals are highly relativistic
