Being in IT, and having been in electronics engineering, I fully
support that (the manufacturing, not the earth hour bullshit).
Turning off the lights doesn't actually DO anything productive.
Lighting (at least the ones that are under normal control) form only a
small percentage of the total power outlay, so even if *everyone* turned
off *every* light it will do nothing for the longer term issues we're
going to have to cover. Less so since it's only an hour.
Google "earth hour sponsors" and have a gander as to what the media is
saying on this, or more importantly, what they're NOT saying.

I found out on Friday that last year's Earth Hour at Melbourne University
ended up being an expensive fiasco. Somebody thought it would be clever
to turn off a power segment, not stopping to wonder what might be on
the circuit. Turns out a freezer full of stuff had to be thrown away,
for a total cost of $36K. So much for saving the planet.

BTW, one can certainly buy 'green' electricity for less than the cost
the candles, but try to charge people the cost of candles for the
power they'd be using outside Earth Hour, and they'd definitely be
protesting even louder.

It's far from clear that that's the problem at all. Governments around
the world seem to have accepted the idea that CO2 emissions need to be
reduced, as have their electorates (in the cases where there are
electorates). But no one actually wants to pay the price. When IPART
announced electricity price hikes in part to cover the costs of an ETS,
I didn't notice people saying "Ah, at last we're getting somewhere." No,
instead there was a lot of wingeing. People want CO2 emissions to be

Well, here are some pictures, from the Earth Hour site itself. OK, there
are no pictures of anyone actually in the process of lighting a candle
(unless I missed them), but there are plenty of candles in view. It's a
reasonable inference that someone lit them.

What kind of freezer has so little thermal inertia that its contents
can't withstand a one hour power outage?

**A Core 2 Duo will use as little as 5 Watts, if not doing all that much.

So not really *in use* then.
Certainly power consumption will rise substantially, when rendering graphics
or playing games, but not if it's just sitting around in an office at
night.

You said "In use, you can add around 20~30 Watts", that's not sitting idle
at night. I just turn mine off then.
Support electronics (not high end graphics, of course) will typically
consume another 20 Watts and a hard drive will use less than 10 Watts.
Figure on around 2 Watts for the monitor and another 20 Watts for
power supply inefficiency.

"Figure" it all you like, but try actually measuring one sometime when it's
NOT idle. And "2 Watts for the monitor", you are joking right!!!
Clearly you know less about electronics than you think you do.

No, you're missing the entire point that I was making. I'm saying that
the scientists have got the message across. The message has been heard.
Earth Hour is not needed to push the message.

Instead of Earth Hour, there should be a "I'm willing to pay to reduce
CO2" hour, with people handing over hard cash.

him what his position is and how he can justify Tony Abbott's insane ideas.

Theres no evidence at all that the people want to hand over money
to reduce CO2.
All Ive ever seen from opinion polls is that the people want the Govt
to do something to combat climate change, but the something is not
defined.
Taxing CO2 emissions is the Govts idea, not the populations.
Pretty obvious from 6 failed Climate change conferences so far, that
the will to reduce CO2 emissions by taxing it simply isnt there.
Time to start looking at alternatives, like building Nuclear Power
plants, and closing down Coal plants.
Zero chance of this happening though.

I agree entirely, except for the very few who've elected to pay a
premium for "green" sourced power.

Yes, for some bizarre reason, the Government assumed that the evident
desire of the electorate for action to reduce CO2 emissions was
accompanied by a willingness to pay for it.

It may happen when coal plants are retired at the end of their useful
lives, and replaced by more expensive (on a total cost basis) gas fired
plants, with a resulting increasin the price of electricity. Then the
government could say "Well, we could have cheaper electricity if we were
to build nuclear plants." The hip pocket nerve is very sensitive.

Instead of "maybe" "figure"ing you'd do better to try some measurements on a
variety of PC's when actually doing those things.

Games

relevant, since we're discussing computers that are left on at night, when

Nope, I *specifically* replied to your statement "In use, you can add around
20~30 Watts." and quoted your higher figures.
But your idea of in use and in standby are the same it seems.


**I said that. CPUs are, for the most part, doing pretty much nothing in
most computers.

Speak for your own, however there are far more things consuming power in a
PC than the CPU alone!

**Mine consumes 1.6VA on standby and 20VA when in use (yes, I've measured
the figures).

So you actually think 20VA = 2W then?

I would expect more modern monitors consume even less. Don't
forget: We're discussing computers that are left powered at night (when no
one is using them).

NO WE ARE NOT.
Have trouble reading Trevor? Hell I even added asterisks to the *in use*
statement to make it obvious. Maybe time for some new glasses?

**Nope. The discussion is SPECIFICALLY concerned with PCs that are left on

gaming or high end graphics). Typical office type workloads barely tax a
modern CPU.

I will make the assumption (since you enjoy making your own assumptions)
that you agree with the original premise that typical office computers
(modern, PC style) consume 500 Watts, at night, when not actually being

remotely close to that much power.

Yeah right! That's why you "figure" "maybe".

**Nope. The discussion is SPECIFICALLY concerned with PCs that are left on

So why don't you answer MY complaint about what YOU wrote, rather than
deciding what YOU want to discuss instead! Obviously you are not prpared to
back up your original sttement, the ONE to which *I* specifically addressed
my argument.
What a waste of time you are.

modern CPU.

Not in dispute, but still does not prove you spurious claim.

**Indeed. An operating hard drive uses more power.

Oh yes you did. You claimed 2W for an operating monitor, then say yours is
20VA, so which is it?

You can make all the assumptions you wish. I
merely quote VERY broad, APPROXIMATE powers,
disputing the FIVE HUNDRED WATTS originally claimed.

Nope, YOU specified a range of power between 70-130 W for a PC *IN USE*,
(50-100W in standby) and it's still there at the top of the post for all to
see!

Since you are being pedantic and mildly annoying,

You OTOH are being a complet pain in the arse!

I will make the assumption (since you enjoy making your own assumptions)
that you agree with the original premise that typical office computers
(modern, PC style) consume 500 Watts, at night, when not actually being
used. Well, I'm here to tell you that you are wrong. They don't use anything
remotely close to that much power.

Please quote where I ever said they did. Like all your assumptions it seems,
you are once again full of shit!

**Like I said: You are wrong. Typical office style PCs do not use anything
remotely close to 500 Watts at idle.

Which was NEVER in dispute in any of MY posts. Try reading what I wrote, not
what you would prefer to respond to.
And of course your claim of 70-130W for a PC *IN USE* is still wrong, and
your continual effort to try and change the subject simply proves you still
cannot support such a statement.

Their useful life is a long way off, with the exception of Hazlewood
which will most likely go gas.
At the same time the NSW Govt is looking at building 2 new 2.2 GW coal
fired plants in the Hunter.
45 years is the typical life of a coal plant.
Also, most of the Coal Plants in Australia are now privately owned, so
the owners will take the least risky option when replacement is needed
and that will be gas, also a very expensive option.
The other problem is that electricity supply is essentially a State
Govt issue, so rising electricity prices will be reflected by anger
against State Govts, not against the Feds.
We will see this on July 1st this year in NSW.

Again, you are making more assumptions. Just like the one where you claimed
that typical office PCs use 500 Watts when not in use.

If you are in doubt, I suggest you read up on the following:

'Energy star'

As it pertains to monitors that are not in use, but automatically switch to
standby.

Really?
What about the nearly 1 million energy customers who have voluntarily signed
up for the GreenPower scheme in it's various forms?
Almost all of those are residential customers, and many of them (like
myself) voluntarily pay a fair bit extra for 100% renewable electricity.

Whether or not they do it because they only care about CO2 levels, and/or
other pollutants or impacts etc, or they simply want a sustainable energy
future is open to debate. But sign up they do.
