  The majority vote model is one of the simplest opinion systems yielding
distinct phase transitions and has garnered significant interest in recent
years. However, its original formulation is not, in general, thermodynamically
consistent, precluding the achievement of quantities such as power and heat, as
well as their behaviors at phase transition regimes. Here, we circumvent this
limitation by introducing the idea of a distinct heat bath per local
configuration, in such a way that each neighborhood value is associated with a
distinct and well-defined thermal bath. Thermodynamic properties are derived
for a generic majority vote model, irrespective of its neighborhood and lattice
topology. The behavior of energy/heat fluxes at phase transitions, whether
continuous or discontinuous, in regular and complex topologies, is investigated
in detail. Unraveling the contribution of each local configuration explains the
nature of the phase diagram and reveals how dissipation arises from the
dynamics.
