  We demonstrate the viability of electroweak baryogenesis scenarios in which
the necessary departure from equilibrium is realized by the evolution of a
network of topological defects. We consider several effective models of TeV
physics, each addressing a fundamental particle physics problem, and in which
the conditions necessary for defect-mediated electroweak baryogenesis are
naturally satisfied. In each case we compare the strength of the model with
that expected from scenarios in which baryogenesis proceeds with the
propagation of critical bubbles.
