DESCRIPTION:Thermodynamic transformations connecting nonequilibrium statio
 nary states have the peculiarity of dissipating\, to keep the system out o
 f equilibrium\, an amount of energy which diverges for a quasi static tran
 sformation. By subtracting the divergent part one can define a renormalize
 d work that satisfies a Clausius type inequality and with respect to which
  quasi static transformations are optimal. A different way of analyzing th
 e energy balance and optimality criteria is to consider transformations ov
 er a long but finite time T developing the total work and the dissipated e
 nergy in powers of 1/T. The diverging terms cancel and one obtains relatio
 ns among finite quantities. \n
