Possibly - try it and see?  You're not supposed to run Ethernet close
to power cabling, but in a domestic situation it often won't make much
difference.

But as Ethernet uses a differential signal and the same potential will
be induced on each conductor it shouldn't generally be a problem.

From what I've read STP can cause as many problems as it solves,
because a poor ground connection or a ground loop problem can make it
perform worse than Cat5.  The main thing to watch is that there aren't
any sharp bends in your UTP cable.
