Standby Mode?
Posted by: u5227470736789439 on 13 March 2006
Dear Friends,
On the Radio (R4) at noon today was an item about standy and the huge energy wastage that apparently occurs because people use standby rather than unplugging.
The thought occured to me that the few watts required to leave our kit just turned on is nothing compared to the waste involved in keeping the heating turned up to an extra degree. I use 24 hour Naim central heating, and bloody cold the room is! Surely, in any case, all the waste is turned to heat, which is factored out with thermostatically controlled heating in the first place! If you use heating at all.
Any thoughts on this, as it strikes me as being as silly (PC rubbish again) as driving your hybrid (electric and petrol) car to the airpost and catching a jet to Miami or whatever. Surely we should shut off every secod street light and ban aircraft (in favour of ships) before worrying at the edges? Perspective please, Dear BBC!
Only a thought from Fredrik

Fredrik,
I'd feel a bit embarrassed about answering your question, seeing I work out here......
I've always wondered what the average oily felt about the environment or global warming or saving energy.....while at the same time spew thousands of cubic metres of gas into the atmosphere up the flare, or several tonnes of oil into the sea in the produced water over-board.....
Yes, all this PC rubbish is getting out of hand these days, but if we all want to do something for the environment it should be aimed at the Americans.....they just don't care, and neither does their government!!
But, to get back on topic, we always switch our telly off instead of leaving it on standby every night, not just when we're going away.... Although I draw the line at the stereo.....
But by all means, please, keep your heating UP.......don't buy those hybrid cars that'll never satisfy your petrol head urges.....burn the midnight oil at both ends so to speak....why....???
'cos you'll all keep me in a job!!
Cheers,
Ali

Oh, and last night I saw a wave lick the top of the leg you can see on the right.... 
I'm due home on Wednesday and that isn't looking likely - bloomin typical....we gained a couple of days at the start of the trip due to the snow, just to pay them back at the end.......

Dear ali,
If you followed what i wrote over the last couple of days, you will realise what a bond I have been lucky to have found with two wonderful Poles (who I mentioned months ago!), and just now they keep my hope in human nature going, given the stupidity and rudeness of those above me have to offer. My goodness human nature is so strange.
good luck out in that horrid sea. I remember as a child sailing through the rigs on Olsen's Blenheim (long since decommisioned - launched in the late forties) and thinking what a price is payed for the energy we so often wtes

Fredrik,
you are a gentleman, and thank you for your thoughts.
Yes I do remember your tale....us humans really are a funny old lot aren't we.....
Don't let the bastards get you down!!
I'd imagine you are sleeping like a baby at the moment after enjoying your vodka, from one of your Poles, a generous gift indeed. I've found the same with Gin, which was also a gift, except this Gin came from Holland......made an excellent G&T.....
Cheers,
Ali
- I'll look forward to mine, first drink, on Thursday now......

A short while ago thet Declan bloke on Breakfast TV announced that you shouldn't leave your mobile phone charger plugged in when not actually charging your phone.
He claimed it costs £25 a year to do so!
I worked out that to cost that much it would need to draw about 30 watts continuosly. 30mW would be a nearer I reckon.

Regarding heat/waste; for a while I even considered using tube amping to get some more heat in my cold listening room in the basement. I got Naim and an extra radiator instead

Probably a dumb question as I don't know how oilrigs work, but is there any reason they can't pump the waste gas off rather than burning it using that flare tower?
I actually quite like the sea; I reckon if I had the eyesight for it I'd consider working on a rig since it's not like I've got anything keeping me on the land...

Frederik,
you are quite correct to some extent. "Waste" heat from domestic electronics will simply heat the room, such that the central heating works slightly less hard. Someone else may be able to comment if using the central heating less often actually reduces it's efficiency (presumably it would have longer to cool down between bursts of activity).
Having a TV & PC on in the lounge, together with two "body heats" is sufficient to keep our lounge warm unless it's pretty cold outside. I'm sure it will be even warmer (maybe even unbearably warm in summer) once our double glazing is fitted.
Standby items will also provide heat 24x7, whilst you presumably switch your heating off at times when you are sleeping or not in the house? There may be a certain value in having a little bit of warmth in the house, maybe even something of a "frost guard" in deepest winter.
One must also consider generating efficiency & transmission losses.
When the heat energy in gas is converted to electricity, a large proportion (ISTR 75%, but I can't be bothered to Google for it), is wasted. That's a generating efficiency of 25%.
There are also transmission losses in the cables & transformers between the power station & your home.
Because of these, it takes 3-4 times as much gas to convert to electricity to be delivered to your home to be converted to waste heat, as the amount of heat that was in the original gas.
Now, your heating boiler won't be 100% efficient either, but I think it's quite a bit better than 25%. Depends how new it is. [There was at least one thread about condensing boilers & efficiency, a few months ago].

As silly as it may be, I don't see why it would be "PC", unless you're George Bush, who claimed until recently that global warming was just a conspiracy by scientists & tree-huggers.

I think it's just that they can't be arsed (ie it's not commercially viable).

Curry on the menu?

Guys, for your interest, here's what I've just pulled from WikipediA about this place...slightly out of date and inaccurate....
The Cormorant oilfield is located 161 Km north east of Lerwick, Shetland, Scotland, in block number 211/26a. It is operated by Shell and licensed to Shell/Esso. It was discovered in September 1972 at a depth of 150 metres. Estimated recovery is 90 million barrels of oil.
The oil reservoir is located at a depth of 2,895 metres.
Production started in December 1979 from the Cormorant Alpha platform. This platform is a concrete gravity platform of the Condeep type. It has three legs and storage capacity for 1 million barrels of oil. The total sub-structure weight is 294,655 tonnes and it is designed to carry a topsides weight of 32,350 tonnes.
The topsides facilities included capability to drill, produce, meter and pump oil. It also has capability to re-inject water to maintain reservoir pressure. Peak production was 24,000 barrels per day in 1979. The platform is also the starting point for the Brent System pipeline, a major communications centre and the location of Brent Log - air traffic control for Northern North Sea helicopter traffic.
In addition an Underwater Manifold Centre (controlled from the Cormorant platform also produces oil. This started up in mid 1983. It has a design capacity for 50,000 barrels per day. Also a single satellite well (P1) is linked to the platform with a design capacity of 10,000 barrels per day.
As you may have noticed from the pic - we have four legs not three!
We're still a major communications centre, but Brent Log is now located on the beach.
The UMC is now fucked, with an estimated few million barrels stuck down there!
We now have the Pelican sub-sea field which we produce from and inject water down...
With a total structure weight of nearly 300,000 tonnes there's little chance of this place going anywhere!! Why do you think Shell keep a couple of billion, each, in the back for the decommissioning of these concrete giants....
As for the flare, they are a necessary evil I'm afraid....
It is the only 'safe' way to vent off (known as blow-down) any un-used gas....which is an integral part of running the process. But is also required in an emergency when everything goes tits up, which happens quite often (especially on here) - you wouldn't want a huge cloud of gas hovering about the platform when the process trips......the safest way is to burn it off.....
Even with our gas compressor running, sending gas at 130 Bar over to the Brent Alpha and eventually St Fergus gas terminal in the NE of Scotland, there still needs to be a means of controlling pressures in our separator vessels, compressor barrel stages, fuel gas system for our turbines etc etc.....unfortunately there's a lot we send up the chuff.....
Oh, and yeah, Basil, the curry's normally pretty rough.......
Cheers,
Ali

And yeah, the telecomms tower is quite a size......it's on the right, next to it is the drilling derek, then a crane boom on the left.....
Jono, home sweet home!! Although I feel like shit as I'm coming off nights....see here - http://forums.naim-audio.com/eve/forums/a/tpc/f/58019385/m/6842935207/p/6 bottom of page 6 and then page 7....
Still nice to be back though!!

it'll be OK as long as it's non-ferrous.
Then we've got the whole three-legs (Fraim) vs four-legs (Cormorant Alpha) debate.
