It is shown that in the situation when the ambipolar field exceeds the heating field the local approximation (LA) for determining the EDF is not applicable even if the energy relaxation length of the electron is relatively small. Therefore, accurate results can be obtained only solving the kinetic equation in energy and spatial variables.
