Starting to think about POWER CONSUMPTION - Blu-ray Forum

franklinpross · 06-04-2009, 07:25 PM

We all know that by lowering the BACKLIGHT, reducing the BRIGHTESS,
and all around smartly calibrating our monitors we can reduce consumption
greatly.
My 40" XBR 2 (default) uses about 221 watts. Calibrated (and noticeably
more pleasant to watch) it uses less.

Can someone tell me what I've reduced that cosumption to . . .all the recent charts (cnet,snobtv . . ) won't give me the answer.

Is it under 150 watts, do you think?

I would say you're pretty close to 150 watts, but it's really hard to guess at something like that. Besides getting a great deal on my LED DLP, the energy consumption was a factor in my purchase. Not a huge overriding factor, but something to consider nonetheless.
Yeah, i think there was a thread a while back concerning this california business. I'm skeptical it will ever become a reality.

If you want to reduce your power consumption you should invest in those green power strips with switched outlets. One of the easiest things to do is to put your PC onto a power strip in the always on slot and then have your display, speakers, printer, etc. on switched outlets. This means that none of those devices will be drawing any power when your computer is turned off. This can be applied to HT devices as well.

As long as politicians are flying cross country in airliners for fundraisers I'll have a hard time being concerned about the power my TV is using.

TRUTH!

You know I was pretty worried about power consumption for a while too. Then I bought my APC H15 Power conditioner, and found that when I have my whole HT rig on and to the volume I like I only use about 370 watts/hour. Which means it takes about 3 hours for me to use 1kWhr, which out here in Pittsburgh is about 12 cents.

Yep. It's the "do as I say, not as I do" metallity that all of these self-righteous congress-critters (and use-to-be's) have. When they start leading by example, maybe I'll give things some consideration. Until then, I'll just enjoy my TVs!

On the other hand, we can be better than them and actually do some good

No one complains about running a welder, or a refrigerator, or electric range, or air conditioner, or dishwasher, or...

Remember people, that nomenclature(sticker) on the appliance with the *WATTS* - that is a rated maximum it will use while running.
Common actual usage is below that number.
Get an ammeter to see what your TV(or other items) are actually using.

This laptop power supply states 1.8A - 216W... Guessing that a desktop with a bit more horsepower than this 5 y/o laptop might be able to eat a bit more, no?

Watts = Volts x Amps

In other words - screw the TV!

I recently reduced my utility bill from $60-70 to $35-40 by replacing my PC desktop with a Mac mini, started using my living rooms HDTV as my computer monitor instead of my dedicated computer monitor (which is now in the closet) and unplugged my mini-fridge. Seeing I almost always have my 42" HDTV, receiver and PS3 or Mac mini on, I'm surprised and happy every time I get these bills.

I don't know what made these politicians think TV's are the culprit of high energy consumption. It's appliances more than anything. But for some reason they want to ban TV's over 40" because they use less power? They must not have heard of Energy Star because most panels go by those guidelines (even the larger Panasonic PDP's).
