Well the Official Government Line is that we have to lead by example, as
in how can the West pontificate about the need for the Far East to
desist from belching carbon into the atmosphere if we aren't trying to
do so ourselves. Like it'll make any difference.

David


I'd like to see the figures - what savings from switching from
incandescent lamps to CFLs are projected to be, together with the
assumptions behind the figures. For comparison, I think the Chinese
are building about two coal powered power stations per week
(URL:http://news.bbc.co.uk/1/hi/world/asia-pacific/6769743.stm).

I suspect there are better ways of achieving more savings than
replacing incandescent lamps. For example, I would have thought that
improving the efficiency of electric hobs and heaters would save more
energy overall. There's an awful lot of resistance coil electric hobs
out there, and mandating the use of induction cookers would help on
the energy efficiency front. There's also a rather large number of
storage heaters - replacing them with air-source heat pumps (aka air
conditioners) would be more efficient (but have the effect from moving
the load from the night-time to the day, which might not be what is
wanted).

Banning architectural lighting would help, as someone has pointed out,
somewhat acerbically.

It's worth pointing out that switching electricity generation from
fossil fuel based to non-fossil fuel will reduce carbon emissions - so
powering incandescent lamps from renewables or nuclear is carbon
neutral. Perhaps one could require those who wish to use incandescent
lamps to use a 'green' electricity supplier. Norway generates more
power per year by hydro than it uses, so CFLs are not especially
popular there.

As someone else pointed out, if you really want to reduce consumption,
reducing the population is a good bet. Don't have kids. A rerun of WW1
would help, and an economic depression will reduce demand as well. A
rerun of the Black Death or the 1918 flu epidemic would also work
wonders. Avian flu anyone? The D-I-Y approach would be to commit
suicide - catchy tagline there - "Save the planet - kill yourself.",
but would be difficult to market. Asking committed environmentalists
to lead by example and drop dead might be taken the wrong way.

Ah, the rallying cry of the Iron Age Restoration Society. If all the
passengers on the Titanic had been issued with teaspoons and told to
use them to bale after it hit the iceberg "something would have been
done". It would of course have had no effect whatsoever on the final
outcome nor would it have delayed it by any measurable amount.

Changing light bulbs has the same order of magnitude of impact as
issuing teaspoons on the Titanic would have. If the population of
the UK was entirely eliminated next Wednesday it would have no
measurable effect on the progress or otherwise of climate change. You
don't solve a problem by ignoring its causes and instead playing
around with stealth taxes in the margins with pious mutterings of
"every bit helps" or "everyone must do their bit" to rally the
ignorati.

If "something has to be done" then that something must involve
massive population reduction worldwide and I don't see any of the
greenygroups being brave enough to campaign for that. There is
nothing more hypocritical than green evangelists with children.



You reactionary old fart! Hooray! There is only one "solution" to the effect
we are having on the ecosystem. As you say, that is for 50% of the world's
population to die (at random). The developed countries' demand for fossil
fuel will collapse and food shortages in the underdeveloped areas will
cease. Anything less is tinkering really. How anyone can imagine that
banning our incandescent lights is going to have any effect alongside the
industrialisation of China and India is bonkers!


And to add to that, what about the deforestation of this world? Isn't it
that trees remove carbon dioxide from the the atmosphere and turn it
into oxygen. That was what I was taught in school.

I might be getting on a bit these days, but I have suffered this all my
driving life.

I have very good night vision and I suffer the same problem. I sometimes
wonder if the good night vision is some compensation for being slightly
red/green colour blind.

At this time of year and at the equivalent sun cycle in spring, I find
it very difficult to drive with the sun to my right when passing trees.
My eyes are adjusting like mad to compensate.

I'm not unduly perturbed (as most of my home is fitted with CFLs anyway)
except that the kitchen and bathroom are fitted with low voltage halogen
downlighters.

Presumably these will go the same way as conventional lightbulbs, won't
they? If so, is there an alternative 'bulb' I'll be able to use, or
will I need to replace the fittings? (and therefore my ceilings :-( )

Something has to be done, unless you do not believe in climate change,
or that the tons of particulates and gases we pour into the
environment have no effect on health. Australia has already banned old
style light bulbs.

For me, the change to CFLs is not an inconvenience at all compared to


I'd agree if the people that make these bulbs didn't persist
in the fiction that an 11W bulb gives the same light as an 60W.

As it is now, you go out and buy some bulbs, find that they
aren't bright enough and have to re-arrange your lighting.

Take them with you and put the originals back.

Reminds me of a storey someone posted here many years ago.
Moved into a new house, only to find the previous owners had
packed up and taken all the light bulbs with them, so a quick
trip to the shops was required. A couple of weeks later,
peered up into the loft, and was surprised to see there was
a lightbulb left behind -- they'd missed one. So he carefully
removed it, packed it up, and posted it on the the previous
owners...

Another government nonsense - the same government that is banning
tungsten lightbulbs is catering for airport expansion that will wipe
out any saving from the use of CFLs many times over.

Its not as true as they would have you believe... the large forests are
mostly balanced ecosystems, so they neither contribute or take away, the
flora produces O2, the decaying vegetation and fauna however consume it.

What they are however is vast stores of carbon. The real problem comes
when you cut em down and burn them, that releases it.

A good proportion of the O2 is produced by algae.

Not quite the same problem, but to me those clowns who have not only

might hit a pedestrian due to their inconsideration. I could genuinely
count on one hand the number of times that I use full beam in a year. I
drive more than 20k per annum.

It is possible to make dimmable fluorescent lamps by separating the
control gear from the tubes. One can see this with larger fittings,
but this has been difficult to reproduce with a small lamp that has
the control gear and tube integrated in one unit.


We had dimmable fluorescents in the lecture theatres at university, back in the
early 80s. It's not like it is a new technology, but you are right about it
being more difficult to handle over just two wires, when the control gear is in
the lamp fitting. I think the ultimate solution would be sending signal and
power separately to the bulbs, i.e. full power piggy-backed with a signal to
tell the bulb what brightness to set itself to. It would work kind of like those
X11 home automation systems, with the receivers built into the bulbs.

In the '80s (potentially installed in the '70s) it would have been

That can be done easily enough using semiconductor ballasts by varying
the AC power input. Our equipment can be dimmed down to about 15% that
way. Eventually there is not enough energy going into the tubes to
keep the filaments up to temperature, and the tube may not start very
well if it's switched on at a low power setting. Lower outputs can be
achieved by feeding the ballasts with a seperate feed of full mains
power and driving the filaments from this via a filament transformer.

when the control gear is in
the lamp fitting. I think the ultimate solution would be sending signal and
power separately to the bulbs, i.e. full power piggy-backed with a signal to
tell the bulb what brightness to set itself to.


Eg Osram/Sylvania quicktronic :

http://www.sylvania.com/ConsumerProducts/LightingForHome/Products/BulbType/Fluorescent/Quicktronic/

It's a simple 0-10v analogue control system which makes it possible to
achieve automatic balancing of light output in display signs as tubes
age.

It would work kind of like those
X11 home automation systems, with the receivers built into the bulbs.


I've not seen any addressable ones - yet.

Transtar were making triac dimmable fluorescent ballasts
in the 1970's. They were the main manufacturer of dimmable
fluorescent control gear at the time. They provide a continuous
heating supply to the tube filaments. I rather wanted one
at the time but couldn't afford them, so I made my own.

Much! Commuting to and from work in the winter - as of about now
requires lights in both directions but only some of which is on unlit
roads. I just wish motor manufacturers would stop putting these silly
bulbs in their headlights and "fog lights". It seems that we are now
conditioned to use lights to announce our presence which increase the
difficulty for others to see pedestrians.

Nothing wrong with the tunnel, it's the bloody underpass shortly before

happen in sunlight.


I'll be aware of what you've said next time I go through (may not be for
a week or two) & come back to you.

Default Govt banning lightbulbs.... wot about halogens?

I'd agree if the people that make these bulbs didn't persist
in the fiction that an 11W bulb gives the same light as an 60W.

As it is now, you go out and buy some bulbs, find that they
aren't bright enough and have to re-arrange your lighting.

The small print on some CFLs I was given used soft-light bulbs for
comparison of their brightness. They are nowhere near as bright as
conventional tunsgten bulbs, especially in the minute after switch on, which
generally is when I need the most light.

It's a pity Einstein isn't still around. - "Energy cannot be created or
destroyed" etc. My 100w bulb may only supply 7 watts of light but it
provides 100 watts of heat. If I reduce the power consumed by light bulbs
in my lounge, the central heating switches on, heating my whole house, using
more energy. In the UK we heat our houses for a large part of the year,
especially when it's dark, why not allow the light bulbs to do it?

That is simple enough logic isn't it.

Why not drop an email to Hilary Benn about it. Don't exceed two
syllables in any word. The person who reads it to him should be able
to explain it in a way that most people should be able to understand.

It's doubtful that he will though.

I trained as an engineer, and for me what I find most disheartening
about this country is that a useless tosser of a bloke like that is
making technical decisions.

I don't know whether or not it's a fundamental tenet of democracy that
people who are completely unqualified make the decisions or it's just
the way we do it. I don't even imagine the way he got the job had
anything to do with democracy, who voted to give him it?

If you only need heat in your lounge then using a local heat source
may be more economical, but much less so if you put it a foot below
the ceiling!

especially when it's dark, why not allow the light bulbs to do it?


Firstly, for a good part of the year you're not heating your house,
and this includes the times in the heating season when it's up to
heat and the thermostat has switched the heating off


Bzzt. Heat input from lamps will still contribute to reduced (gas )
consumption by delaying the time when the thermostat energises the
boiler again.

and secondly electricity is a high CO2 fuel


But it could come from renewables or nuclear. then it wouldn't be.

so the environmental pressure is to
cut the use of electricity - why do you think that electricity is
something like 3x the price of gas per delivered kWh?


Inefficiency, bad organisation, too many people in the distribution
chain (Stood in Sainsbury's with clipboards or walking round housing
estates) taking a cut ?

I've seen it done, I don't think it's even that uncommon.
