Determining the distance of quasar absorption outflows from the
central source and their kinetic luminosity are crucial for
understanding their contribution to AGN feedback. Here we summarize
the results for a sample of nine luminous quasars that were observed
with the Hubble Space Telescope. We find that the outflows in more
than half of the objects are powerful enough to be the main agents for
AGN feedback. The sample is representative of the quasar absorption
outflow population as a whole and is unbiased towards specific
distance ranges or kinetic luminosity value. Therefore, the analysis
results can be extended to the majority of such objects, including
broad absorption line quasars (BALQSO).
