Many recent studies have addressed the role of the entropy production rate (EPR) in characterizing nonequilibrium steady-state fluctuations. In active matter systems the production of entropy occurs on the scale of each individual particle where persistent mechanical motion is generated from a local extraction of energy and subsequent dissipation of heat. In this talk I will present unpublished results on the EPR in these systems, with a particular emphasis on active matter with (metric and ferromagnetic) alignment interactions, in conjunction with a review of the available literature. More specifically, I will discuss both analytical as well as numerical results we have obtained on the Toner-Tu field theory of the transition to flocking, as well as for some particle based models of aligning active matter.
