Uh, cite? No, never mind, the above statement is just
pure BS.

In the average home, 75% of the electricity used to power home
electronics is consumed while the products are turned off.

That isnt relevant to the total power use of the house tho.

And is dubious with some of the home electronics like TVs and
computers, which just happen to be the main uses of power in
the average home even with just the home electronics.

That is not the same as "appliances use more power 'off' than on."
The power usage rate is certainly less during standby than during
regular usage. Duty cycle of off time vs. on time can certainly
mean that an appliance *may* use more energy over time during
standby, but only because it is in standby for much longer periods.
When dealing
with kitchen appliances, the standby current is very low relative to
in use current because most kitchen appliances tend to be fairly big
energy users. I doubt the LED clock on my stove uses as much energy
in 1 year as one burner uses to boil a pot of water in 5 minutes.

The big hits on standby power are going to be VCRs, computers, TVs
and the like. Those tend to not use a lot of power when in use, so the
relative difference between standby and in use is not as much to overcome.
