Google for Vampire Taps. You won't notice a thing unless you have very
very sensitive voltage etc measurements happening.

Like everything else (eg how many locks you have on your house), it all
depends completely who your adversary is and how much protection you
require against it. In the end it will come down to a delay for the
adversary and annoyance on your part with the problem that if the
adversary wants your information hard enough they will 'nicely' ask.
