Before revision:  Based on an energy estimate for the viscous-plastic sea-ice model we define an energy for the elastic-viscous-plastic and viscous-plastic sea-ice model .
After revision:  To show that the stabilized Crouzeix-Raviart approximation is qualitative consistent with the solution of the continuous sea-ice model we define an energy for the elastic-viscous-plastic and viscous-plastic sea-ice model .
