Some detail is written at each SCF step:
! total energy = -2165.02128665 Ry
estimated scf accuracy < 7.8E-13 Ry
smearing contrib. (-TS) = 0.00106813 Ry
internal energy E=F+TS = -2165.02235478 Ry

The total energy is F=E-TS. E is the sum of the following terms:
one-electron contribution = -814.89710227 Ry
hartree contribution = 541.02007057 Ry
xc contribution = -540.16756065 Ry
ewald contribution = -1350.97776243 Ry

You can have more details by modifying electrons.f90 around line 1400, i.e. to print etxc and etxcc separately.
