  Tunneling of electrons of definite chirality into a quantum wire creates
counterpropagating excitations, carrying both charge and energy. We find that
the partitioning of energy is qualitatively different from that of charge. The
partition ratio of energy depends on the excess energy of the tunneling
electrons (controlled by the applied bias) and on the interaction strength
within the wire (characterized by the Luttinger liquid parameter $\kappa$),
while the partitioning of charge is fully determined by $\kappa$. Moreover,
unlike for charge currents, the partitioning of energy current should manifest
itself in $dc$ experiments on wires contacted by conventional (Fermi-liquid)
leads.
