The lowest Power Factor usually comes from motor (Aircon, Refrig),
transformer (neon lamp, radio, TV, PC)
But todays equipments are designed with Green in mind. Yes they are
not perfect with 1.0 power factor, but at least 0.8 or more.
So if we are still running a lot of old equipments, then maybe the
additional capasitor, may help us to increase pf.

video of the TV station test is unfortunately a dead link.

Power factor (ie, power drawn by non-resistive loads) is of course very real
- but I don't know of any situation where the power company is calculating
your power usage on anything but watts. So for a home user it matters not,
while for the power company it matters quite a bit and is a a very good
reason to add capacitance to the system.
