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. :-)

The Philips website lists them under "Specifications" for each set.

Most sets appear to be 1W in standby.

Thanks - that's useful information.

You're right, of course. I knew that, but ended up compounding the
confusion by my sloppy wording. Do you think it would help if we
measured the energy consumed in joules? Or perhaps calories? Everyone
knows what they are...

We could. It would be perfectly valid, but the kilowatt-hour, or kWh, or
"unit" seems to be the usual measure of electrical energy. It's the one
that appears on our electricity bills, so I would expect everybody to
know, at least in a practical sense, what they are.

It's not as if someone is making you use an STB. Oh, they are...


I hadn't thought of that. What a good point.

Just about every DTT STB I have seen is without a power switch, so unless
people are going to switch them off at the wall, that's a lot of STBs all
sitting on standby - and an increasing number at that. Also, in most homes,
I'm sure you'll find the STB, TV, Video/PVR and DVD all plugged into a 4-way
adaptor and powered from one wall socket, and will therefore be left with
power all the time for the benefit of the recorder.

It seems to me that Sky+ users have the most energy efficient setup - one
box which needs stand-by mode and the rest can be powered off. Until DTT
PVRs with dual tuners become the norm rather than separate STBs all over the
place. I'm still waiting for one with a DVD recorder to appear at a
mass-market price.

The key to all this is reducing the silver box-count, in addition to turning
the telly off at night...

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

A kWh is 1000 joules isn't it, or is it 3600000 joules, I suspect it's
the second actually. 1 joule = 1 watt for a second. Thus 1kwh is
1000 * 3600 joules. So, essentially, kwh are joules with a different
name. 1kwh = 3.6Mj

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

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

I disagree with that too on the basis that you cannot just replace kWh
with Joules -- you must do some scaling for the figure to still
represent the same physical quantity.

A better example of equivalent units would be the Pa and Nm^-2 -- 1000
Pascal = 1000 Nm^-2, just as 567.8 Pa = 567.8 Nm^-2. Indeed, the Pascal
is defined as one newton per square metre.

Wouldn't a tuner need to be in standby anyway for the timer to work?

All the more reason to get an "Intelligent Mains Extension Lead" from Maplins.
The catalogue number is L22BK, and it costs 29.99GBP. The one showing on their
web site is slightly different from the ones I have (which only cost 24.99), as
it now includes a telephone and modem splitter, though I've also seen them in
DIY shops so you may be able to get the cheaper ones too.
