Average jet power released by radio AGN as a function of stellar mass for the population of all massive galaxies between 0 < z < 0.4 (black hatched). The secondary y-axis (right) shows the corresponding average jet kinetic energy released, obtained by multiplying $\overline{Q}$ with the look-back time. The contributions from compact and complex radio AGN are shown with light and dark blue shaded regions, respectively. Red dotted and dot-dashed lines indicate the 0.1% and 5% of the average radiative energy output as a function of M_*, respectively. The purple dot-dashed line represents a ‘canonical’ 0.5% of the average radiative energy output, which is used for comparison to the kinetic output throughout the paper.
