The drift-wave model of anomalous transport is used to interpret electron energy balance in discharge data from five tokamaks. A consistent interpretation requires the inclusion of impurity radiation losses which, in some cases, become comparable with the Ohmic power input. For discharges with a well-defined radial electron thermal flux the value of the coefficient in the drift-wave transport formula is determined along with bounds on the variation of the coefficient that are consistent with the interpretation of the data.
