We review one of the most accurate low-energy determinations of αs. Comparing at short distances the QCD static energy at three loops and resummation of the next-to-next-to leading logarithms with its determination in 2+1-flavor lattice QCD, we obtain αs (1.5 GeV) = 0.336+0.012-0.008, which corresponds to αs (MZ) = 0.1166+0.012-0.008. We discuss future perspectives.
