I'm no science major but I know enough to know this is a cyclic planet,
and while cooling killed the dinos but not us (at different times)
because we could adapt. We have to adapt again, not adapt the planet.
That can't be done.

Here is another one. In 1348 the black plague was
endemic. It did not `just happen.' That time marked the
end of a very warm period in northern Europe during
which the population grew very much larger than before.
Then the climate got cold and wet, crops failed, famine
roamed the land, and people were going to die. The
black plaque was the proximate cause.

And how many kilowatts went up the chimney?

In a modern furnace, very few... they're something like 90-95% efficient.

In a 40 year old furnace, plenty... electric just might beat those out.

I'm still waiting for someone to chime in that heat pumps (for heating) are
really the way to go if you're in a milder climate. I've never had one, but
it seems that people either think they're the greatest thing since sliced
bread -- significantly saving on heating bills -- or just snake oil.
(Although interestingly no one thinks air conditioners are snake oil...)

They don't think it's snake oil, exactly; it's more like, "Well, how the
hell do you pump heat OUT OF that freezing cold out there, into the
(relatively) warm room?" - i.e., it's kinda counter-intuitive, like a
gas refrigerator.

but environmentalism and economics
must find a way to coexist.
Ut can easily. Economics suggests spin a natural occurance correctly and
you can sell all your envirobunkum products for all the wrong reasons
for a far greater profit than if you sold them for the right reasons.

If something is sold as cheaper, people expect the POS price to be
cheaper, not the length/replacement cycle.
if you sell something as longer lasting and saving the planet, people
expect it to cost more, but quite often will pay it.

Environmental economics in action. It pays to sell green.

I have a cunning plan also based on a similar related application of this
theory. Never tell ppl about your real intentions.

Politicians find this works well for them too.

Wrong about the myth. GW is most probably real

George Washington?
if it wasn't the Petro
companies wouldn't be channeling millions into 'independent organisations'
to attempt to rubbish it.

Assuming your premise is true, your conclusion doesn't follow: what
follows is that PC's (petroleum companies) accept that the perception
of GW (global warming) is real, and may hurt their BI's (business
interests).

On the subject of fluorescent lights, it's seemed to me that some
of the newer, inexpensive ones (the spiral-shaped screw-in
models), emit a much more comfortable spectra than the old long spectrum
tube type that have been popular in office lighting for so long
[1]. I used to say that I couldn't stand fluorescent lights, but
these newer ones seem to emit a softer, yellow-tinted light.

Are they using a different substance in them that fluoresces at a
different frequency, or are they just using tricks with filtering the
light? I would imagine that filters would reduce their efficieny
somewhat...

offshoot to soft tints, look up "pink" in

beware.) The "color" of the light is usually expressed in degrees K

kelvins are not degrees.
stamped on the side of the electronic ballast, (or some other consumer
euphemism, like "DayLight," "SunLight," etc.,) right next to the
cautionary label about using the light near navigation or
communication equipment that functions in the few tens of mHz. range

not millihertz.!

Actually, what I SHOULD have said is:

It doesn't matter how cheap the gas is,
the heat you get from a light bulb is FREE
because you're paying for the light, not the heat.

That makes the heat actually CHEAPER than free
since you have to buy less gas.

Are you aware of just how HOT the Antarctic is compared
to 0 deg Kelvin?

Sure, but it's still cheaper to buy 1kWh of heat from the gas or fuel oil
company than it is from the electric company!

A more interesting comparison might be how efficiently you can light a room
with gas!

hmm, how to get gas into a fuel cell...

Al Gore came on Opera yesterday and said we could save 20% of the
energy our light bulbs use if we switched to more expensive florescent
bulbs.

Don't know why but this word 'FLUORESCENT' must be one of the most
misspelled.
And the various 'spell checkers' know it!

The most common misspelling is "Flourescent".

I don't know how anybody can jump to the conclusion that there is a
conspiracy to keep certain bulbs off the market! No evidence is
presented here.

Also; assuming that 'Fluorescent bulbs' here means those that either
screw or plug in, as direct replacement for conventional incandescent
types, apparently there is definitely a significant energy saving. But
on whether they are worth while from an overall 'economic' point of
view 'The jury still seems to be out'?

The cheap ones are not reliable they either fail long before their
stated life or fall apart or don't work very well in the low
temperatures that area fact of life for much of North America and parts
of Europe.

We can buy either conventional incandescents or fluorescent bulbs
almost anywhere!

Currently one can buy four cheap bulbs in a package (4, 60, 100 watt
etc.) for anywhere from 88 cents to around a dollar Canadian. Plus
sales tax that works out to about 22 cents US or roughly 15 UK pence.
They last a reasonable time and if not left on for long periods don't
use much energy. Since we use electricity for heating anything then
bulbs 'waste; contributes to our heating.

Yes, incandescents do provide some heating, but they provide it summer and
winter whether you need it or not; and they most probably dump the heat in
the wrong places. You want heating, you should put your electricity through
a heater.

Over the expected lifetime of an incandescent bulb, the cost of the bulb is
insignificant compared to the cost of the energy it uses.
True, this is not the case for fluoresents, but the saving is still
significant.

100W incandescent bulb uses about 10$ US electricity per 1000 hours.
A comparable fluorescent will use $2 - $3 in the same time, and should last
6x longer.

There are places where an incandescent is more useful - inside cupboards, on
dimmer switches, and some PIR triggered systems, but for main room lights
you should be confident of saving at least $10 US per year for each
fluorescent bulb you buy.

Heh. According to the packet it came in, I'm currently using a

Unless I have an electric heater on or the washing machine, my largest electrical
load now is easily the PC.

When my disk died, I moved to a Toshiba laptop that has one of those
energy star labels on the cover. My power usage dropped 100Kwh/month.

I think it was the terminal that was using most of the power.

BOOM! Quite efficiently, but all the light shines at the same time.
