Ok so I got hold of an current/power clamp meter and the results are (the
price is amount per bill (quarterly) assuming you are charged at
14.9c/kWhr):

Black&Decker Microwave Standby: 1.58W ($0.51)
Brevelle Blender Standby: 28.08W ($9.17) (has backlight clock... power
button appears to do literally nothing but light another LED)
LG MicroWave Standby: 4.87W ($1.59)

Toshiba 32" LCD TV Standby: 7.41W ($2.42)
Sony stereo Hifi Standby: 28.85W ($9.42) (Playing Radio: 48W average)
Sony Playstation 3 Standby: 10.75W ($3.51)

 Motorola Cable Modem 'Standby':    5.35W    ($1.75)
Dlink Wireless Router On/Transcieving (average): 11.28W ($3.68) Power
Adaptor with nothing plugged in: 9.6W ($3.13)
LogiTech 5.1 PC Speakers On but no input: 17.4W ($5.56) 'off' via power
button: 14.88W ($4.86)
Sony Trinitron 21" CRT On: 112.8W ($36.83)  Standby: 32.64W ($10.66) Off at
power button: 32.52W ($10.62)
ATX PC (Dual Core, 2GB RAM, 2 HDD's, 2x Optical Drives)

Intersting to note how high the standby current is on the PC, not even worth
using unless your down time is going to be under 10 minutes!
Can anyone else measure theres, maybe I just have a crappy PSU thats wastes
heaps of power just to delivery the 5V standby/USB? My PSU is an ANTEC 600W
a few years old.

Nintendo DS Charger (5.2V 450mA) Nothing plugged in: 0.62W ($0.20)
Nokia 5v 890mA Phone Charger: Nothing plugged in: 0.28W ($0.09) Phone
plugged in and fully charged: 6.86W ($2.24)
HP Laptop 19V 4.7A adaptor: Nothing plugged in: 3.6W ($1.18) Laptop plugged
in and fully charged: 3.70W ($1.21)

DSE Indoor TV Antenna with Amp: On: 3.14W ($1.21) Adaptor with nothing
plugged in: 2.78W ($1.18)
Sony Playstation 2: Nothing plugged into adaptor: 6.67W ($2.18) Standby:
6.74W ($2.20)
DSE CRT Digitor 48CM TV: On:    58W average ($18.97) Standby: 9.58W ($3.13)


This is typically what would be left on standby/'off' 24/7 at my place:
Black&Decker Microwave 1.58W ($0.51)
Toshiba 32" LCD TV Standby: 7.41W ($2.42)
Sony stereo Hifi Standby: 28.85W ($9.42)
Sony Playstation 3 Standby: 10.75W ($3.51)
LogiTech 5.1 PC Speakers 'off' via power button: 14.88W ($4.86)
Sony Trinitron 21" CRT Off at power button: 32.52W ($10.62)
ATX PC Standby: 22.22W ($7.26)
Nintendo DS Charger (5.2V 450mA) Nothing plugged in: 0.62W ($0.20)
Nokia 5v 890mA Phone Charger: Phone plugged in and fully charged for 12hours
per day: 6.86W ($1.12)
HP Laptop 19V 4.7A adaptor: Nothing plugged in: 3.6W ($1.18)
DSE Indoor TV Antenna with Amp: On: 3.14W ($1.21)
Sony Playstation 2: Standby: 6.74W ($2.20)
DSE CRT Digitor 48CM TV: Standby: 9.58W ($3.13)

Total Standby/Off power: 148.75W, 1.3megawatthours per year, $47.64 per
bill.

And that doesn't include other stuff that runs 24/7 like the
router/modem/PVR PC/fridge/alarm system etc.

Wow, that's huge. My ViewSonic 22" LCD display takes 32.8W operational and
0.63W in standby (as measured by my SC power meter kit).
I deliberately chose it for its low power consumption.

The power readings are all wrong because the current is not reading in phase
with the voltage. So pretty much ignore them all. have heard good things
about the SC kit so i might check it out



Re: More standby power usage (bit more accurate this time)
If you are paying about $48.00 per 1/4 year for standby this is about
average for the consumptions you listed. If you were to start doing
total shutdown of everything you may find yourself replacing power
supplies and doing more service than leaving them on. The cheaper cost
per device is just to leave them on their normal standby.

Besides, you have to be able to know and read the difference between
true and apparent power. I don't believe in actual fact your equipment
is as bad as it apears to you!

Also, I am sure that your power company probably has a minimum billing.
Your standby cost may be fitting in to that minimum cost. Where I am, we
are billed every second month. The minimum is something like $62.00
Canadian per billing. Because we have sever winters with sub-zero
temperatures, and very warm periods during the summer months our power
consumption is very high. Last year my total power bill was over
$1600.00  Canadian. So, you have it very good!

As for saving the environment, before thinking that saving electricity
saves the environment you should look at how the power is generated.  If
they are using combustion fuels to generate electricity, then there will
be some savings of carbons in the air if you consumer less. If your
power company is using flowing water for power generation, it will make
no difference if you use more or less. The load on the generators will
not use any more or less water, because it is all from the same water
flow.

The main polluters in the world are not from western countries. They are
from the new and growing countries that are taking manufacturing goods
for the rest of the world. They are going through a massive expansion
and growth. There is no regard in these countries for the environment.
The fix is to find a way to stop buying their products. But, this will
never happen because everyone is dependent on what they make.

What will fix the pollution problem is when the air in the world is so
bad that nobody can breath anymore, and the atmosphere has lost all its
ability to block the harmful radiation from the sun. When the world
population decreases to near zero from the massive pollution and damage,
there will be no more need for the mass manufacturing, and then the
earth will be able to recover.

What pollution problem ? Sure if you go to Mumbai/Bombay you'll discover
what pollution is but the air in western countries hasn't been cleaner for
centuries.

I've just run a Jaycar meter over a few things. before starting, I connected
it to a 150 watt halogen work light, it read 150 watts. thats a very rough
and ready calibration, but better than nothing.

Item                                                        Power on
Standby
Sony 70cm CRT TV                                80w
22w
Samsung 80cm HD LCD TV                   163w                          17w
LG 106cm HD plasma TV                       330w
25w
Tivo DVR                                                24w
(runs 24x7)
Dell D620 laptop                                     60w
7w
Desk top PC (4x 7200 disks)                  70-90w
14w

I have no idea how accurate the meter actually is, I will run some tests
when I can work up the enthusiasm, but the figures are pretty well what I
would expect. You can save a little money and CO2 by truning it all off,
peronally I only do so when I am going away for a couple of days or more.

**  For low level calibration:

 A 56 kohm resistor should read 1 watt.

 A compact fluoro lamp should read its nominal power rating in watts. (Let
it warm up fully and must be in near new condition.)

 Any main rated capacitor of a few microfarads should read zero watts.
