Query: The kinetic luminosity function and the jet production efficiency of
  growing black holes   We derive the kinetic luminosity function for flat spectrum radio jets, using
the empirical and theoretical scaling relation between jet power and radio core
luminosity. The normalization for this relation is derived from a sample of
flat spectrum cores in galaxy clusters with jet-driven X-ray cavities. The
total integrated jet power at z=0 is W_{tot} ~ 3x10^40 ergs/s/Mpc^{3}. By
integrating W_{tot} over red-shift, we determine the total energy density
deposited by jets as e_{tot} ~ 2x10^{58} ergs/Mpc^{3}. Both W_{tot} and e_{tot}
are dominated by low luminosity sources. Comparing e_{tot} to the local black
hole mass density rho_{BH} gives an average jet production efficiency of
epsilon_{jet} = e_{jet}/rho_{BH}c^2 ~ 3%. Since black hole mass is accreted
mainly during high luminosity states, epsilon_{jet} is likely much higher
during low luminosity states.
