Give me a break. The article might well be in fiction story book. And I'm
supposed to believe what Rebecca says? Most men tech writers are
technically challenged, Rebecca, come on. Well, yes Rebecca, when you
compare a 28" crt TV to a 42" LCD TV, the LCD TV with twice the viewing
area and almost 4 times the resolution will use more power overall, but if
you break it down to power per pixel, it uses far less than even the
smaller crt screen. And an orange will also produce more electricity than
an apple.

I would wager that most people care about the bottom line of their
electric bill more than they care about power per pixel.

 It's still comparing apples to oranges. For a more realistic comparison
you might try:

32" CRT TV:

versus

32" LCD TV:
http://www.sharpusa.com/files/tel_man_LC32AV22U.pdf


 In this apples to apples comparison the LCD uses an additional 15w of
power, but offers HDMI and PC inputs, more than triple the audio output
power, weighs less than 1/3 of the CRT set and is (of course) much slimmer
in size. Now it's up to the consumer. Are the additional perks of the LCD
worth an additional 15w of power? According to the originally referenced
article, the difference between these two sets, provided they were run 24
hours a day for an entire year, would result in less than $16 added to your
annual electric bill.

I suppose that you're suggesting, what with the cost of energy
skyrocketing over the past few years, and the questionable state
of the global environment, that "most people" will selflessly or
penuriously keep their CRT TVs for the next decade or two,
rather than spend the cost of the new panel, whatever its size,
and/or any additional monthly energy costs to operate it?  Hmmm,
you could be right!  Perhaps this xmas' shopping season will be
an indicator.

Nope. I'm suggesting what I said. No more, no less.

Just out of curiosity what's the average power bill or typical range (they
bill every 3 months in Sydney so maybe in the US it's monthly) for a 3
bedroom house in a moderate climate in the US say like San Francisco or Los
Angeles (doesn't snow in any major cities in Australia).  I have a potable
power meter and when I swapped from my European 28" CRT TV to a 40" LCD my
bill went down by 60%

That's strange as the 28 inch widescreen Crown CRT TV in my den consumes
90W, however Googling around seems to come up with figures around double
that for a 40/42 inch LCD TV.

I doubt that changing any appliance in a modern home would drop the
elecricity bill by 60%. Maybe switching from electric heat to something
else, but certainly no single appliance.

I suspect that replacing my air conditioning with nudity would drop
the electric bill by more than 60% (in Texas).  I have gas heat and
gas hot water, so except for the blower heating doesn't use much
electricity.

Now, if you meant dropping the whole energy bill by 60%, it wouldn't
happen.

Take a look at what you snipped. The claim was that replacing the TV
caused the bill to drop 60%

 He said he had a portable electric meter (actually he said potable so
maybe I am assuming too much) which suggests to me that the 60% is the
difference between the two TVs.

oops just checked my records, the Nordemende CRT drew 600 watts and the
Samsung uses 190 watts. The drop was recorded on a little electronic device
you point to the TV or Iron or microwave to register it's power (HPM make
them). Our main power meter is about to be changed to an electronic 'smart
meter' that registers every half hour and gives you a read-out in the
kitchen or living room so one can 'modify' ones lifestyle, with different
charge rates for different times of the day. Looks like I'll be running my
pool pump and clothes dryer, dishwasher, heat pump etc at midnight.... at
around 7c per kilowatt hour versus a reported 35c during the day. My last
quarterly bill was $600 that included all of the above and two
airconditioners.. Sorry about Hobart! it's the cardinal sin in Australia we
on the mainland tend to leave Tassie off the map - I stand corrected! It
even snowed in Sydney for 2 minutes in 1958 - didn't make the sidewalk...

What was that Normende CRT? It can't be a TV in any case at 600W.

I have an old Sony 1272 CRT projector that I'm contemplating
installing, and it has a max rated input power of 540W. My older Sony
722 CRT projector is rated at 155W, but draws less than 100W.

If it is a TV, then I would say the meter you are using is not doing a
good job.

Many simple energy meters you connect in line with the equipment
does't take the power factor into account. I have one like this and I
have recently bought one that does measure the PF, and lots of modern
equipment have really low power factor, which shows as high apparent
power consumption but low real power consumption.

It was one of the early stereo models (circa 1986 ish) and had 3 built-in
100 W (RMS) amps imported from West Germany as it was then and moded for
Australian conditions. It really was physically hot to be near

I just checked my German SABA 29" CRT TV of about the same vintage. It
is a NICAM stereo model, about 2x25W, and it draws around 64W real
power, or 100VA.

I'm still sceptical at that 600W figure.

Come on people, you can't compare crt to LCD and get any meaningful
results unless they have the same viewing area, and the same resolution.
Meaning they both need to be HDTV's or SDTV's. When you do a proper
comparison the LCD uses far less power than a crt based TV. Otherwise
consider a 7" LCD only draws 5W, compared to your 28" crt drawing 90 or
whatever. Get the point?:-)
