And how many kilowatts went up the chimney?
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.

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

into the
(relatively) warm room?" - i.e., it's kinda counter-intuitive, like a
gas refrigerator.

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

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...

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.

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

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.
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.

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?

Why should that matter? Savings at the consumption end should result
in proportional savings in transmission.
Not 20% of _total_ energy distributed.

It is a fact of human consumption that, if a resource is not
used in one place, it will be used in another place. There is
no savings (I'm getting really tired of hearing that word) but
a redistribution.

Now, at the consumer end, there is and incentive to reduce
power usage; the bills are lower and they can spend money
on something else...like a 20'x20' HDTV.

There are methane fuel cells, but what does a fuel cell have to do with
lighting? Make electricity, and run CFLs?

Haven't you ever seen a gas light? ;-)

"In this year, 1817, at the three stations belonging to the Chartered Gas
Company, 25 chaldron (24 mł) of coal were daily carbonized, producing
300,000 cubic feet (8,500 mł) of gas, which was equal to the supply of
75,000 Argand lamps, each yielding the light of six candles. At the City
Gas Works, in Dorset-street, Black-friars, the quantity of coal daily
carbonized amounted to, three chaldron, which afforded a quantity of gas
adequate to the supply of 1,500 Argand lamps; so that twenty-eight
chaldron of coal were daily carbonized at that time, and 76,500 lights
supplied by those two companies only."
--- http://en.wikipedia.org/wiki/Gas_lighting

So, does anybody wanna do the arithmetic on how much light you get per BTU
of gas vs. electricity? ;-)

I suppose we should count the fuel for the electric plant and for the
refinery here. ;-)

I have an office like that: 9'4" x 9'6", 8-foot ceiling, and I leave all 4
computers running, and even if it gets down to the 40's, when I come in in
the morning, it's always nice and cozy-warm. If it gets too warm, I just
open the door - it opens out onto an unheated factory.

Speaking of fluorescent lights, just a couple of months ago they got a guy
to redo my ceiling light (which is obnoxiously bright, but there's not
much I can do about it), and the guy refurbished this 8-foot fixture with
iron ballast; he took the ballast and even the socket thingies out, and
installed new socket thingies and electronic ballasts, and essentially
turned the 8' fixture into two 4' fixtures end-to-end. He also gave me
one of those screw-in fluorescents for my desk lamp.

Since the PHB is so cheap, I'm ass-u-me-ing that he's expecting a
significant savings on lighting. :)
