A simple parameterization scheme has been developed in terms of which the energetically important effects of convective heat transfer may be included in an energy balance model of the thermal history of a planet. The scheme is illustrated in the context of a discussion of the thermal history of the Earth in which mantle wide convection is assumed and the internal energy is completely primordial. The observed mean mantle viscosity from postglacial rebound strongly constrains the model.
