Based on the theory of the radio evolution of supernova remnants and the theory of X-ray emission, an expression is derived for the energy of supernova eruption directly in terms of the observed radio flux density and X-ray luminosity. This method is used to estimate the energy of the supernova explosions in LMC and SMC. The calculated values fall in the range 10 to the 49th - 10 to the 51st ergs, with the values for Type I supernovae systematically smaller than those for Type II, at about 10 to the 49th ergs. It is pointed out that the most likely cause for the discrepancy between the statistical and theoretical N-D relations is incompleteness of data. It is also pointed out that in the two clouds studied, the vast majority of large sources are still in the phase of adiabatic expansion.
