Good read, Smurf1976.

In fact, his very last *recommended* option of "putting on warmer clothing" rather than using more energy for space heating was the one we used last year that cut over 35% off our winter gas space heating bill. All we did was buy one of those ultra-light-weight thermally efficient Made-in-China blankets for our bed, then turned down the comfort setting for night operation by 3.5C (from 18.5C to 15C).

Honestly, apart from having to dash a bit to the closet to jump into our tracksuits and ugg boots, we coped easily with the change. Mind you, it makes it a lot easier not being encumbered with screeching young'uns demanding 25C all year round "or else"!. LOL

Can you imagine all those thousands of nasty, black, CO2 balloons we must have kept grounded too!!

New Years Cheers,

AJ
 
Do you run your air conditioning/heating all year round, AJ?
 
:topic:
I also notice sydneysiders dropped more than 10% (519 to 464) on average water usage this year too - oops compared to 1974 lol (probably a particularly wasteful year to use as datum lol )

If we say that the average suburb is about 6,000 people (very roughly), then how much water did a suburb use then in 2007?
464 litres x 365 x 6,000 = 1 gigalitre

this is the volume that would be contained under the harbour bridge deck (50m high ) x its width ( 50m) x its span between springing points (500m - less the triangular bits at each end)

Hi Julia.

Barring the occasional unforeseen extreme weather event, for about 2 months in the changeover between early autumn and late autumn - we rarely have ducted gas heating on, and in the changeover between early spring to late spring - almost never have the ducted evaporative cooling on. So in total, about 4 months with virtually no use of either system.

While it has been possible to reduce the heating bill significantly with very little outlay and some judicious re-programming of the controller, lowering the cooling bill would take a lot more moolah (would need to install lots more roofing insulation, double-glazed windows etc, etc. Since we are paying rent for the house, this definitely won't happen unless the landlord wants to personally lash out big time!

Cheers,

AJ
 
Hi Aj

Wow, I'm really surprised you need it that much in Victoria! I'm in Qld, four hours north of Brisbane and only use the air/con about five nights a year and never during the day. Do houses in Victoria have ceiling fans?
Good point about the insulation. Few houses here are built with any insulation at all. Unbelievable.
Must admit in NZ we needed the central heating in winter.
 
Adelaide 43, Melbourne 42 (43 in some parts), even Hobart 33. Already 41 in Adelaide and it's only 11am local time there.

Also very low humidity and, in Hobart at least, strong winds are forecast this afternoon. So regardless of the global warming debate, let's hope no idiots start fires - I'm sure the firefighters don't want to spend New Year's Eve running around with hoses trying to save houses etc.

Not sure about Vic and SA, but it's a fire and watering ban day today in southern Tas as with the strong winds the risk is pretty high. Let's hope the only fire tonight is the fireworks.

Smurf, we had fires in Sydney a few years back - arsonist-initiated .
I met some firies who were bludy exhausted - the supervisor said to me "we caught one the other day - I've got two utes, one with a rifle (usually to put dying animals out of their misery) , one without. He's lucky I was driving the second one that day. "
 
Well I think everyone in Adelaide, Melbourne and Hobart would have been quite warm last night. Ridiculously humid in Tas too made it feel warmer than it actually was. Very low humidity though in Vic and SA.

But climate change? Or just natural variation in the weather? One event doesn't prove anything other than that it was warm last night. It's the trend that counts.
 
Exactly Smurf, its the trend that counts, a few nights means little, but facts such as Vic having its hottest year on record should be enough to raise eyebrows ..... Im sure we can expect more ...

 
I'll know we are serious about global warming when:

coming into summer we put the daylight saving clock back an hour not forward
If you stop and think (and I'm talking here about normal activity) before we fiddle with the clock, in the morning:
a) there is more daylight already
b) it is much much cooler for all forms of activity and life generally
c) the air is cleaner after the reduced activity avernight
in the afternoon the sun has heated everything up and there is less daylight (1.5hrs) after work than there is before (2.5hrs)
so if we went back an hour instead of forward there would be more cooler daylight and a longer period of it (3.5hrs) before work gets in the way

but I'm sure the current decission makers will have some reason for moving the clock the wrong way - its just that I haven't heard one yet
 
Three quotes from Prince Philip over a 20 year period ....

Fair to say that he was ahead of his time with some of these quotes..

Where did you get that hat? (1953)
To his wife, the Queen, immediately after her coronation



PS treefrog - some good points there
PS (edit) but as Smurf says next post - only if people bother to get out of bed lol.

Modern (post-war) daylight saving in Australia was introduced in Tasmania for the 1967-68 Summer at the request of the Hydro-Electric Commission specifically as a means of reducing electricity consumption during the electricity supply emergency. Other measures included rationing, outright bans on various uses of electricity and the purchase of gas turbines and a generator ship.

If we didn't have daylight saving then it would be light at 4am!!! Not much point in that when very few people get up any earlier than 6am unless they're a shift worker etc. Also it would be dark at 8pm in mid-Summer without daylight saving and of course that means the lights on for an hour longer - avoiding that was the original reason for it.

Also I'd argue it probably does a lot of good for health - the day that daylight savings ends is the day most stop exercising in the evening and watch TV instead. Very noticeable change there.

Maybe some different issues in Queensland etc?
 
Record power demand in Victoria today. Peaked about 4:40pm local time at 9439 MW but it was over the previous record for quite a while.

Energy demand keeps going up, up and up. People may well be concerned, but not enough to actually switch anything off it would seem.

At the time of the peak, 7879 MW was from local generation, 1357 MW from NSW, 594 MW from Tasmania. 391 MW was being exported from Vic to SA. The price was $7600 per MWh at the time of peak demand - about 150 times the average. It went up to $9999 in SA.

The good news: Everything worked properly and the lights stayed on. And a nice profit for those selling power into Vic or SA no matter what the source (unless they're hedged). Even better for those buying some back right now at $50.

The bad news: CO2.
 

Computers/electronics for Christmas and air conditioning???
 
no question in my mind ...

"I don't know why people are concerned about global warming !
why don't they just turn their air conditioners up??! "

oh great reserve - no problem then !!

Meanwhile fires out of control in Ballarat.

 
I'm beginning to think Jeremy Clarkson is right:

Eat, drink and burn fossil fuel, for tomorrow we die.
 
they say a picture tells a thousand words ...

... :evilburn: .......:bad: ...... :nosympath.........:viking:........

The truth is that my earlier facetiousness is spot on. There is no point anybody doing anything until the leaders lead instead of spreading messages, least of all me.

I'm going out to get my Range Rover on the weekend... and I'm driving to the pub. Whats the point of living like an 18th century subsistence farmer as the rest of the world carries on regardless... including the "messengers".
