Take a small freestanding fridge as an example.
Google suggests a cost £20 a year for electricity if it is A rated. An old C rated fridge may be using 2 to 3 times that amount of electricity. So you could save £40 a year on the electricity. So a 4 to 5 year payback time at best.
Narrower doors on cake shops is the solution.

Probably - or at least sleep them. It would also make sense to shut down the printers and scanners when you're not using them. What proportion of the time that they are on are they in use?
but then the disabled lobby will be complaining that wheelchairs can't get through

Thats a better ROI than a solar panel anyway :-)
Its the sodding 10 minute warm up time when you want them that is the issue, and the fact the plugs are totally inaccessible..
But is it a net gain or loss taking into account old people who would otherwise die of hypothermia?

And businessmen and MPs pay good money to Miss Susie Spanktastic to be told they're naughty boys...

The plugs thing is your own problem.
I know it's the warmup time you're trying to avoid, but really, how much do you use them? Give us some numbers.
embarrassingly little. thats why i want to know what they use...
10 mins what for? The desktop PC's to boot, that's a bit excessive. Mine is slow probably 2 or 3 mins, long enough to make a cup of coffe anyway. It does get switched off, makes me more productive. No, "I'll just quickly (ha!) check email/usenet" when I'm passing the machine.
Inaccesable sockets can be solved for =A35 by three remote controlled sockets from Asda.
This thread has prompted me to see how much the stuff on the UPS is taking. It never drops below 23% load on a 750VA UPS, so thats around
170W, half of my night time base load... Hum, maybe it is time to look at low power miniITX based server instead of the current 800MHz PIII.
I have a rack of five servers, all mini-ITX, and the whole lot (apart from the switch that's in there) is under 150W.
the scanners take forever to warm up,Pcs well this one about 30 secs, BUT its backup runs over night. The wife's G5..a minute or so.
interesting.
I can thoroughly recommend this: I have an Atom 510MO board..in the smallest case that would take two disk drives. Its faster than the PIII it replaced..64 bit and a gig of ram, and gigabit ethernet.
more than good enough for its purpose.
superb.
That's roughly what the vendor told me it would be.
Even better if you can avoid hard disks....one of them runs off a CF card (read only).
cant avoid that. Need lots of read writes. CF dont last very long with a lot of writes.

Not always the problem it seems. Decent flash will cope with a lot of write cycles (over 100,000 IIRC) - it depends whether your writes are spread around or concentrated into a few areas - and whether the unit has any decent wear levelling circuit.
To put it in context, a decent flash (eg Transcend) assuming a few GB size upwards written over an over from start to finish, continuosly will last (MTBF estimate) some decades.
Putting a swap file on a cheap unit however will not.
I know they don't. Hence the read only bit I mentioned.
NFS mount a file on one of the other machines...
well if you can tell me where to get 500GB flash for less than 30 quid that will take constant random writes and reads fr 5 years I'll buy some.
This is the NFS file server, begorrah! At least with OS-X I don't need ***ing appletalk on it as well. Just samba
