I'm running a simple example using Cu and the Fermi energy listed is about 
double that in the literature; mine: 13-15 eV (depending on pp). I've tried the 
suggestions concerning increasing nbnd and cutoff energy as well as reducing 
the mixing coefficient and using all of the different pps on the site. I'm 
using espresso-4.0.3 (in order to run epw.x) but have also checked w/ 5.0.1 and 
get the same issue. My input is below:
 &control
    calculation='scf',
    prefix='Cu',
    pseudo_dir = 'pp/',
    outdir='./',
    tprnfor = .true.,
    tstress = .true.,
 /
 &system
    ibrav = 2 ,
    celldm(1) = $lp,
    nat=  1 ,
    ntyp = 1 ,
    ecutwfc = 80.0,
    ecutrho = 800.0,
    occupations = 'smearing',
    smearing = 'cold',
    nbnd = 22,
    degauss = 0.005
 /
 &electrons
    mixing_beta = 0.1
    conv_thr =  1.0d-8
 /
ATOMIC_SPECIES
  Cu 63.55  Cu.pbe-d-rrkjus.UPF
ATOMIC_POSITIONS crystal
Cu        0.000000000   0.000000000   0.000000000
K_POINTS AUTOMATIC
16 16 16 0 0 0

Is there something I'm missing here or is the Fermi energy output not what I 
think it is...I apologize in advance if this is something obvious that I've 
overlooked.
Thank you,
