  By combining the recently derived X-ray luminosity function for Galactic
X-ray binaries (XRBs) by Grimm et al. (2002) and the radio-X-ray-mass relation
of accreting black holes found by Merloni et al. (2003), we derive predictions
for the radio luminosity function and radio flux distribution (logN/logS) for
XRBs. Based on the interpretation that the radio-X-ray-mass relation is an
expression of an underlying relation between jet power and nuclear radio
luminosity, we derive the kinetic luminosity function for Galactic black hole
jets, up to a normalization constant in jet power. We present estimates for
this constant on the basis of known ratios of jet power to core flux for AGN
jets and available limits for individual XRBs. We find that, if XRB jets do
indeed fall on the same radio flux--kinetic power relation as AGN jets, the
estimated mean kinetic luminosity of typical low/hard state jets is of the
order of <W_{XRB}> ~ 2x10^37 ergs/s, with a total integrated power output of W
\~ 5.5x10^38 ergs/s. We find that the power carried in transient jets should be
of comparable magnitude to that carried in low/hard state jets. Including
neutron star systems increases this estimate to W ~ 9x10^38 ergs/s. We estimate
the total kinetic energy output from low/hard state jets over the history of
the Galaxy to be E_{XRB} ~ 7x10^56 ergs.
