I agree, and I'll probably buy one, but I can imagine the blank looks I
would get if I tried to explain to most of my family what it did and why
(let alone how)...

And so the shops will sell them another box. Are you still amazed?

Not amazed that the shops are taking advantage of the situation. Just
amazed that the government is stupid enough to let it happen.

Thay could tack an increasing tax on analogue receivers and a balancing
decreasing tax on digital receivers. Do you reckon the Daily Mail &c would let
them get away with that? ;-)

1 joule = 1 watt for a second.

1 Watt is one joule per second, e.g. 1W = 1J/S.

Not 1J = 1W/S as you suggest.

That is not what he suggested. You just misinterpreted it.

I wonder how much energy (food/fuel/computing/paper etc) she uses
to tell people this? I did try to measure the 'pseudo-off' power
consumption of my PC, but found it was less than my power meter is
capable of registering.

FYI, this is typically 4 watts. I've observed "off" power
consumption in the range 1 to 8 watts on PCs that _aren't_ faulty.

Mine must be unusually efficient then!

Either that, or your 'power meter' is one of those that fails to
register anything below 7 watts. :-)

Hardly likely, given that I routinely use it to measure standby powers
of 1 or 2 watts.

Oh well, I guess your PC _must_ be unusually efficient then. :-)

I use an analogue AC/DC wattmeter. It's a german one called Metrawatt
with 100, 200, 500 volt and 1, 5, 25 Amp range settings. It has a
mirrored scale calibrated 0 to 100 and 0 to 250 in steps of 2 and 5
units respectively. This meter is designed to work on single and three
phase supplies.

If I accurately set the zero and use a magnifying glass, I can quite
easily interpolate to 1/4 watt readings on the 100v/1A settings.
Strictly speaking, I should be using the 200v setting for our 230v
(nominal) mains supply, but the multiplier resistor seems to be
conservatively enough rated to withstand this 'abuse' (which it has for
the last several years. :-).

Just out of curiousity, what is your PC's standby (shutdown)
consumption? I can reduce mine to zero by the simple expedient of
switching off at the PSU's isolator switch. This also shuts power off to
the monitor and speakers because they are fed from the auxilliary mains
socket.

In this case, I'm saving a total of 10 watts standby power, so worth
the trouble of reaching round the back to switch the mains feed off.
Mind you, according to taskmanager, I haven't done this since almost 70
hours ago! The consequence of DVB-T and scheduled recordings I suppose,
but I'm still astounded at that uptime figure (I switch the monitor off
though when I retire for the night and there are early morning
programmes in the schedule).

Where can I buy a cheap mains socket adapter to measure the power ?

Tchibo have them for £9.99

A kilowatt hour is about 9p.

For 10 watts that's a saving of £0.0009 an hour, or just over 2p for
every 24 hours that you have your PC switched off completely.

Or am I missing something?

£7.88 a year?

Or you could look at it in terms of carbon emissions saved. I'm not
knocking it. All I ever objected to at the start of this thread was
people making stupid claims about standby power consumption.

Well I don't know, because I was unable to measure it! So less than a
watt, I guess.

I will have another look at this, just in case I've misremembered. I do
recall being surprised, and going to the trouble of looking up the ATX
PSU spec to see how much power it had to be able to supply in standby.

Which assumes he'd never switch it on to use it ;-)

From an environmental aspect you're quite right. Personally I couldn't
be bothered with reaching behind my PC when I power it down to save 2p a
day. I do find I'm more conscious lately about conserving energy however.

Plug a small table lamp into one of the switched outputs and they might get
the idea.
