My presentation will focus on the theory of galaxy-scale outflows powered by accretion disk winds in luminous AGN. I will review the basic theory of wind-blown bubbles, including the issue of momentum vs. energy conservation. I will then discuss predictions for the different ways in which galaxy-scale AGN-driven blast waves can be observed (including in narrow line region emission and absorption, molecular gas, and non-thermal emission from relativistic particles accelerated at wind shocks). Time-permitting, I will also show some results from galaxy evolution simulations aiming to understand the very uncertain effects of AGN outflows on galaxies. Specific questions that I would like to bring up for discussion include the origin of molecular gas in high-velocity outflows, the origin of momentum fluxes >> L_AGN/c inferred from outflow observations, and the effects of AGN outflows on star formation in galaxies.
