  In models for thermal baryogenesis from particle decays, the mass of the
decaying particle is typically many orders of magnitude above the TeV scale. We
will discuss different ways to lower the energy scale of baryogenesis and
present the corresponding lower bounds on the particle's mass. This is done
specifically for the inert doublet model with heavy Majorana neutrinos and then
we indicate how to extrapolate the results to other scenarios. We also revisit
the question of whether or not dark matter, neutrino masses, and the cosmic
baryon asymmetry can be explained simultaneously at low energies in the inert
doublet model.
