I haven't read it, but I notice that most appliances with a
standby mode are now micro power consumption, which can be
left plugged in without any significant load. My most recent
Nokia phone charger falls into this category.

The items which aren't seem to be those which are UK-specific
such as cable and set-top boxes. This is probably because we
don't have any requirement for micro power consumption in
standby mode, whereas many other countries now do, and in
order to sell a product internationally, it's now pretty
much an essential requirement.

I did a check on a number of LCD monitors and laptop power
supplies a year ago. Monitors (HP) were all marked Tco'03
which requires very low standby power consumption,
although the monitors were all very much lower than even
that standard requires. The Toshiba PSU's didn't claim any
such low standby power consumption, but they too were
insignificant (both well below 1W). So neither were worth
recommending staff to bother switching off.

Leaving a laptop PSU connected to a laptop with a battery
in it causes significant standby power draw though, even
when the battery is fully charged.

If you got put off by the apparent huge PDF tome you had to download (as
I was initially!) actually, the phone charger article is at another
(very easy-to-read) link - worth a shufti!:

Interesting stuff. Unfortunately logic and maths don't have the mass appeal
of soundbites.

Channel Five ran a news story the other day about how ~ 25% of all land,
sea, and pond species had become extinct since 1970 (they had different
numbers, but to two significant figures, for each category). Evidently
no-one in their newsroom did a sanity check. The web site featured most if
not all of their other stories of the day, except this one. I wonder why.

All you have to do now, if you wish to be convincing, is to come up
with an instance where someone claimed that just unplugging phone
chargers would stop global warming.

Good luck in your quest.

There are going to be two more Chinas by 2050, with all people demanding a
more equitable standard of living across the planet. Plastic bags and items on
standby aren't going to cut it. We need to drastically cut the birth-rate,
however our Gordon appears intent on financing further growth.

Well a few years ago there was much talk of methane fuel cells being
used to power mobile devices. Whatever became of that idea?

I think that production of un-necessary stuff is a bigger problem:

eg. * Getting a new phone charger with your new phone when your old one was
okay (should be optional to make you think)

* Making and importing (from China) cheap batteries that don't last very
long - waste of resources - waste of transport and increase in landfill
polutants - for little benefit.

* Shipping cheap Xmas tat from China for it to end up in the bin by the end
of January.


The "stand-by" issue is a red herring as most modern devices are incredibly
low consumption - yet the reports are often based on old equipment.

Except that almost every phone that anyone in my family has ever owned
(even from the same manufacturer) has needed a different charger. Why
the hell couldn't that (ie voltage/plug type) have been standardised
years ago, which would have allowed the above eg to have happened?

Nice try, but incorrect as usual. Rudeness in the posting too. Do
keep it up.

BTW one fairly obvious fact in that link is that British Gas do not
claim that just unplugging phone chargers would stop global warming.
It is always mildly amusing to see the straws some will clutch at.

That's because there is no such thing as Global Warming.

Ah, proof by assertion. Very convincing.

I'll stick with the IPCC thank you, unless you are able to debunk
their arguments.

On the contrary arguments, I like the entry for 13/11/07 at
http://www.realclimate.org/index.php/archives/category/communicating-climate/reporting-on-climate/

"There is an interesting, if predictable, piece up on the BBC
website devoted to investigating whether there is any 'consensus'
among the various contrarians on why climate change isn't happening
(or if it is, it isn't caused by human activity or if it is why it
won't be important, or if it is important, why nothing can be done
etc.). Bottom line? The only thing they appear to agree about is
that nothing should be done, but they have a multitude of
conflicting reasons why. Hmm…

"The journalist, Richard Black, put together a top 10 list of
sceptic arguments he gathered from emailing the 61 signers of a
Canadian letter. While these aren't any different in substance to
the ones routinely debunked here (and here and here), this list
comes with the imprimatur of Fred Singer - the godfather to the
sceptic movement, and recent convert from the view that it's been
cooling since 1940 to the idea that global warming is now
unstoppable. Thus these are the arguments (supposedly) that are the
best that the contrarians have to put forward.

"Alongside each of these talking points, is a counter-point from the
mainstream (full disclosure, I helped Richard edit some of those).
In truth though, I was a little disappointed at how lame their 'top
10' arguments were. In order, they a false, a cherry pick, a red
herring, false, false, false, a red herring, a red herring, false
and a strawman. They even used the 'grapes grew in medieval England'
meme that you'd think they'd have abandoned already given that more
grapes are grown in England now than ever before (see here). Another
commonplace untruth is the claim that water vapour is '98% of the
greenhouse effect' - it's just not.

"So why do the contrarians still use arguments that are blatantly
false? I think the most obvious reason is that they are simply not
interested (as a whole) in providing a coherent counter story. If
science has one overriding principle, it is that you should adjust
your thinking in the light of new information and discoveries - the
contrarians continued use of old, tired and discredited arguments
demonstrates their divorce from the scientific process more clearly
than any densely argued rebuttal."

no, it's localised warming on a global scale, is it ?

There are lots of uses of the word "could" however which rather suggest
BG not being willing to put its money where it's mouth is.

I wonder why they don't quote lower figures and use the words "would"
and "at least"

I took a look at "the Register" who have a report on the book at
http://www.theregister.co.uk/2008/06/20/mackay_on_carbon_free_uk/.

On the first page they have the following:

"He emphasises that the book isn’t quite finished yet, and says he’s
always glad to hear from someone who has something to add or has
spotted a mistake.

"In Without the hot air, MacKay examines our total energy usage in
the UK, and then tries to provide a similar amount of energy but
without using any oil and gas."

So, the mistake was very easy to spot, it is in the second paragraph
I quoted.
