  We consider the random walk among random conductances on Z^d. We assume that
the conductances are independent, identically distributed and uniformly bounded
away from 0 and infinity. We obtain a quantitative version of the central limit
theorem for this random walk, which takes the form of a Berry-Esseen estimate
with speed t^{-1/10} for d < 3, and speed t^{-1/5} otherwise, up to logarithmic
corrections.
