Likely a spokesperson reading from a prepared script. Which is why Mair

It did seem bizarre, so I did some measurements on some USB power supplies
I found around the house. I found an Apple 2.5 A output iPad charger, a
Lenovo 1.5 A charger and a Garmin 2.1 A satnav charger.

With their USB outputs disconnected they all just about took 1 mA from the
mains. I put the current consumption for various activities in a pdf at:

Excellent. I was going to do the same with a real transformer type. Be
interesting to see what that takes with no load.

That would be interesting. I've always avoided using doorbell transformers
as I didn't know the quiescent power.

I got 2.1 units. Of course, I don't know what the waveform or
power factor are like.

There's some fire risk to leaving chargers switched on so I'd regard
it as bad practice to leave them switched on when not in use even if
they are using minimal electricity.

Not when they are designed properly there isn't.

so I'd regard it as bad practice to leave them switched on
when not in use even if they are using minimal electricity.

So do you switch everything off when not being used ?

If you do, more fool you.

How do you cope with things that do need to be left switched on? Cookers
and microwaves with a clock. PVRs, etc?

the biggest threat to humanity comes from socialism, which has utterly

I did. It looked blank to me. I wanted to know what *he* thought was on
page 2.

It's blank. The second page is just an artefact of the Excel to PDF conversion
(LibreOffice to PDF conversion too).

Honestly. I put it in PDF so people wouldn't have to worry about Excel macros
and now I'm hiding the secrets of the Illuminati in blank pages.

Oh well all right. You may pass. But you were suspected by us in the
Microsoft Police as one who presses the return key 50 times at the end
of their Word Document, as if it were a typewriter. Such miscreants are
routinely hauled off to our re-education camps.

I don't understand any of this but.... might it explain my annoyance
when printing off a pdf from some utility supplier who has admonished me
about paper saving, that the second page only contains one line!

I was listening in the car. It was a really *REALLY* bad interview,
using someone as an expert who didn't have a clue. Why on earth did
the BBC think a person who runs a switching website (Ann Robinson?)
would know the first thing about energy saving?

It is ok, albeit ineffective at saving energy. Unplugging switched mode wallwarts is generally pointless anyway. Green bull as usual.

If you think about it disconnecting the device will make most modern
PSUs shut down. Leaving them plugged in will stop them shutting down. It
may save a small amount of energy.

Dennis is quite right. Energy will be saved.
Plus a reduced fire hazard.

If you take into account all the stuff round the place, if it was all left energised, it would be significant.

Its down to PSU chip design, they use microwatts when there is no load
and milliwatts when there is. The power saving is very small from that
but the charger in the device will also use a bit of energy too.
The power saving is small.

It's not small it's negative. The electrical energy saved is dwarfed by the energy expended in going over there & switching it off. So you get to spend a little time for negative outcome. Typical greens.

Even for 50Hz transformer type wallwarts I calculated one saved something like 45p an hour from going round turning them off. IRL of course you end up with flat appliances now & then, the result of which dwarfs any green savings.

And this kind of silliness is meant to save the planet!
