    We have compared a new QCD calculation by Clay and Ellis of energy-energy correlations (EEC's) and their asymmetry (AEEC's) in e(+)e(-) annihilation into hadrons with data collected by the SLD experiment at SLAG. From fits of the new calculation, complete at O(alpha(s)(2)), we obtained alpha(s)(M(Z)(2)) = 0.1184 +/- 0.0031 (expt) +/- 0.0129 (theory) (EEC) and alpha(s)(M(Z)(2)) = 0.1120 +/- 0.0034 (expt) +/- 0.0036 (theory) (AEEC). The EEC result is significantly lower than that obtained from comparable fits using the O(alpha(s)(2)) calculation of Kunszt and Nason
