We compute the renormalized one-loop quantum corrections to the energy density T00(x) and pressure T11(x) for solitons in the 1+1 dimensional scalar sine-Gordon and kink models. We show how precise implementation of counterterms in dimensional regularization resolves previously identified discrepancies between the integral of T00(x) and the known correction to the total energy.
