  We point out that, contrary to what is believed to hold for QCD, renormalons
are genuine in QED; i.e. the ambiguities which come with them do not require
cancellation by hypothetical non-perturbative contributions. They are just the
ambiguities characteristic of any trivial ---and thus effective--- theory. If
QED remained an isolated theory up to an energy close to its triviality scale,
these ambiguities would surely hint at new physics. This not being so, the
renormalon ambiguities in QED lead to no new physics, not even to
non-perturbative contributions within QED itself.
