  We combine cosmological simulations with an AGN luminosity function
constrained by optical surveys in order to create a realistic AGN distribution
in which to model AGN outflows. The outflows are modeled with assumptions of
spherical symmetry and energy conservation. We study the importance of the
kinetic luminosity of AGN outflows in determining the fractional volume of the
IGM filled with outflows as a function of redshift. We find that kinetic
luminosities of < 10% of the bolometric luminosities are required or the entire
IGM would be filled with outflows at z=0. We also examine the effects of
varying the AGN lifetime and the bias parameter, which describes how tightly
correlated AGN are to high density regions. We find that longer lifetimes
(tau_{AGN} ~ 1 Gyr), as well as small bias parameters increase the filling
fraction.
