Really? Stink. Just go here and poke around:
-
Can anyone explain this concept I read on the energywise website where they recommend exchanging a 100W incandescent with a 20W CFL? Does this change in wattage give essentially the same lux? (And therefore are they claiming that for any given light-level the CFLs are 5 times as efficient?)
(I know Andrew has already answer this, but, to summarise...)
YES!!! And ain't that awesome?
-
I think the dimmer thing is still an issue, and wonder if there are CFLs on the way that can be dimmed?
Yes.
Given my chandelier is made of burnt and blackened wood the Mr Sparkerel argument doesn't really sway me (although I'm yet to find a candle-shaped CFL to fit)
Here.
I just wish that larger CFL bulbs (i.e. >20 watts = >100 watt equivalent incandescent) were more generally available.

I get so sick of saying this to otherwise interventionist liberals. "They're idiots, don't believe what they're saying, you don't actually believe that!"
If they're conservative and/or irrational, try the man-donkey-love erotica.
If that doesn't work, try food safety and telecommunications standards. Technical standards really throw libertarians.
-
Well, yes, but surely unless you plan on burying the wood it's part of the short-term carbon cycle anyway?
Not if you didn't chop it down for firewood in the first place. 8-)
-
I do wonder if Labour considered how many votes, and seats in the house it was worth to ban incandescent light bulbs?
My beef is, how can we tolerate a media/political environment that is so toxic, and so completely off its nuts irrational, that the dumbest and craziest arguments can come from left field and sink these basic energy efficiency measures.
I'm not saying that they should've died in a ditch over it. Just saying it's fucked up that they even had to, for something so simple and benign.

I hate earth hour! It just feels so sanctimonious and smug. I think I'll go and turn on every light and apppliance while its on ;-)
I was pissed off with the ban on incandesant bulbs, just because of the way it was done - I'd already swapped most of mine over, quite happily, but I didn't like having another ban imposed.This is one area where the market would have led people naturally to the better environmental choice.
Michael:
No. Because a) there was so much misinformation going around about safety and functionality, and b) because the price signals for electricity doesn't get through. Power gets charged in one big bulk, and you don't know what you're being charged for, or where the savings comes from. And because the savings for a lightbulb is spread out over its lifetime, people don't buy a lightbulb and immediately see the savings. Hence, the market doesn't work in this situation.
There are plenty of situations where the market doesn't work and the state steps in. It's not a lefty thing, it's an economics thing.

We were not in favour of a full ban on incandescant bulbs.
Andrew, was this public information at the time? I don't recall this being reported, since presumably, Brownlee would've been all over it, right?

CFLs are cheaper at producing power, through savings in replacing incandescant bulb usage, then building new power stations by a factor of about 7
Thanks for your input on the thread Andrew - it's always great to hear from the guy who was actually at the heart of it. Out of curiosity, did you see the Chandelier Defence coming? While writing this, I tried to put myself in your shoes, and I'm not sure if I'd be fucked off or just completely dumbfounded at the energy efficiency arguments being countered by "but my chandeliers won't sparkle".
We were not in favour of a full ban on incandescant bulbs.
We thought a market based solution with high quality products demonstrating benfits was better then forcing people into behavioural changes. We had some evidence from the UK that home owners were removing dedicated CFL fittings and putting standard light fittings in becasue they didn't like being forced into having dedicated CFLs.
I didn't realise that "people being dicks" was actually factored into your consideration. Still, changing sockets and stockpiling bulbs is a pretty high barrier ain't it?
Surely, the Garth George types must suffer the same kind of credibility gap as environmentalists who are all talk and no action. "Meh, all my friends know I'm wasting energy, so why bother actually making an effort to waste energy?"
There are issues with power quality when you increase the penetration rates of CFLs (they are non linear loads that cause power factor issues and harmonic problems - which can mean extra problems elsewhere in the supply system and yoour appliances). The quality of the bulbs has a major impact, banning bulbs would allow a flood of the cheaper CFLs in that excacerbate these issues.
Didn't know that. Interesting problem...

Um, Keith, aren't you out by a factor of 1000?
(Panic!)
Wait, don't freak me out like that. 8-) I used Wh for household consumption, and I divided it by 1000 for CO2e/kWh.
38 checks later, yes, that is still right.
