  A recent concept of local noise sensor is extended to measure the energy
resolved electronic energy distribution $f(\varepsilon)$ at a given location
inside a non-equilibrium normal metal interconnect. A quantitative analysis of
$f(\varepsilon)$ is complicated because of a nonlinear differential resistance
of the noise sensor, represented by a diffusive InAs nanowire. Nevertheless, by
comparing the non-equilibrium results with reference equilibrium measurements,
we conclude that $f(\varepsilon)$ is indistinguishable from the Fermi
distribution.
