Perhaps he really said we could save 20% off our TOTAL energy
consumption by switching to compact fluorescents.

That number sounds wrong. 20% in Las Vegas..maybe. But not
total energy. How much of our total electric power is used
up in transmitting it?

We have Global cooling(Ice Ages) as part of the natural cycle, so why
not Global Warming. Maybe we can't do shit to stop it happening, maybe
we are just inconveniencing our selves for nothing, and maybe we are
just paying "green" taxes becauase we are told to and all it is doing is
making government revenue. Maybe the human race is going to get wiped
out at anytime soon anyway, no matter how many solar panels, wind
turbines, BioFuels and organic lentils are installed, consumed or used
as fertiliser.

Global warming is happening, and will happen because
planet Earth is still emerging from another major
glaciation. Unless another volcano blasts a metric
buttload of SO2 into the atmosphere ushering in another
dark ages as in 635 AD. Mankind is such a bunch of
babies thinking they have any influence over anything.
Wankers. Maunder Minimum. Little Ice Age. Google it and

Ah! A refreshing breeze of intelligence!

Did anyone see "Mini Ice Age" on the History Channel a few nights ago?

Why should that matter? Savings at the consumption end should result
in proportional savings in transmission.

"Well, you shouldn't discount all that free electric heating you get
with incandescents (it's free, because you've already attributed the
cost to lighting). In the winter that waves on fuel bills, and in the
summer it help our airconditioners run longer, to efficiently
dehumidify the air."

It's only "free" if you have electric heat rather than natural gas or fuel
oil, both of which are cheaper. Even then, it's arguably not quite as good as
a floor heater, since most of the heat will stay up on the ceiling where the
lamp is rather than being forced down to circulate among the people -- I
imagine draftier homes or a ceiling fan may mitigate this, however.

That being said, for people with electric heating, in winter I think running a
few spare PCs on BOINC or something similar is a pretty good idea!

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

No, warmer air due to lighting makes the thermostat kick on
less often reducing your consumption of gas or fuel oil.

Hold on there.

With incandescents, a huge percentage of wasted output takes the form
of near-infrared light. Look at a spectrum plot for a typical bulb.
NIR is basically the same as red light, so if the fixture reflects
light well, then it probably reflects NIR. Both NIR and visible light
will heat the surfaces in the room.

Solar heat evaporates annually some 2-3*10^14 tons of water. Compare
this with any amount of water you'll be producing. Some sense of
proportion is needed.

Amount of water per vehicle per day might be minimal, but multiply that
by millions of vehicles per day it might make a small difference.

It is not that the amount of water per vehicle per day is minimal, but
that the amount of water per billion vehicles per year is still much
smaller than the netural varioation in the figure above. Do the math.

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!
And how many kilowatts went up the chimney?

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

But it is a good way to make us pay taxes.
And like good little sheep, the majority of joe public and wife will
bend over to recieve their orders.
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.

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.

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.

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).

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
