Going back to our lounge and 6 x 40W candles on average we would replace
one of those every month. I've yet to replace the CFLs, though they could
do with it 'cause after 5+ years they are getting a bit dim.


Candle lamps (and golfball lamps) are just disasterous.

You need a better fitting such as a single 200 Watt GLS lamp hanging
on it's own mains lead inside a swirly cloudy glass bowl full of dead
flies. ;-)

they're hugely less efficient to make,

Per bulb I'd agree but over the five+ years that the 6 CFLs have been in
service I'd have consumed over 60 tungsten bulbs. Not quite so clear cut
now is it?

That's simply the price you pay for running very small, very hot, 40
Watt GLS lamps


and, unlike tungsten filament ones, they can't be recycled at all easily
(not that one does: the unit cost of filament bulbs is so low it's not
sensible, but you could, easily, if you really wanted to).

You can recycle pretty much anything if you put your mind to it.

First they should do it, then they should talk about it.

The economics are doubtful but it may come as a bit of surprise that money is
not the only factor. Slowly (very slowly) the fact that *everything* is a
finite resource is starting to dawn.


Then the economics will eventually catch up, if their arguments are
not specious, that is.

It is the compulsion and lack of democracy now that we take issue
with. This compulsion being engineered by the big lamp manufacturers
(Hello Philip, where's your "Gloeilampen Fabreiken" "the noo" )
schmoozying up to the EEC Commissioners, because they can make more
money by shutting their European GLS lamp factories and importing
CFL's from China.

As for energy-saving, that's specious too.

Nearly 4 units/day saved on the lounge lamps.


But you're not getting the same quality or quantity of light, and the
bulbs are less easthetically satisfactory (Specially true of CFL's
bought 5+ years ago). I 'm presuming you chose a fitting that takes
decorative candle lamps for easthetic reasons.

The 'waste' product from incandescent bulbs is heat, but annually our
major use of them coincides with the coldest period in the UK, so
effectively we're using them as partial electrical heaters.

On pure engineering terms yes but how much *real* contribution does that
make to the warmth of the room? 4/5ths of buggar all IMHO.

So why compell us to change.

Can't say I
noticed the oil consumption go up when I swapped 240W of tungsten for 54W
of CFL. Less than 200W of extra heat an hour, that really is nothing in
space heating terms. The wind blowing 5 mph faster will have a bigger
impact on space heating requirement.

Assuming our power stations are 'clean'

Which they aren't.

I thought it was a "Global Warming" argument ??


that's a potentially _good_ use of electrical energy, compared, say, to
burning Russian natural gas that's irreplaceable.

So we burn irreplaceable Polish high sulphur coal instead...

SO2 is scrubbed out of flue gases as Calcium Sulphate which is used to
make plasterboard.

< http://climatecalm.org/archive/drax.htm >

Drax was opened 1974 and is the newest and most efficient of the UK's
coal-fired power stations. This refers to its units having FGD plant
fitted which removes 90% of SO2 emissions, and to the fact it emits
less CO2 per unit of electricity produced than other UK coal-fired
stations.
