We calculate the naive defect energy $\Delta E$ of Ising spin glass(SG)models in two dimensions using conjugate boundary conditions. We predict that,in the $\pm J$ model, the averaged value $\bar{\Delta E}$ converges to somenon-zero value in the thermodynamic limit in contrast with $\bar{\Delta E} = 0$in the Gaussian model. This prediction is incompatible with previous ones butsupports a recent Monte Carlo prediction of the presence of the SG phase atfinite temperatures in the $\pm J$ Ising model. We also calculate the interfacefree energy to confirm it.Comment: 10 pages (Tex file) and 6 figures (Eps files). e-mail  shira@iwate-u.ac.j
