Power comsumption; RPTV has the best bang for the buck; Two updated tests.

In spite of all the gloom and doom for RPTV technology, there still is a bright side. Green is in.

Crutchfield just did this test on the TVs' they sell regarding power consumption;
http://www.crutchfieldadvisor.com/le...page=2#results

Cnet has another list. This is NOT the orginal article from a year ago, but a much updated version with models up to Nov. '07;
http://reviews.cnet.com/4520-6475_7-...3.html?tag=nav

(Crutchfield based the test on 6/hrs a day and Cnet based it on 8/hrs. Both sites used $.10/kwh)


Observations;
1. The Panasonic 59" Plasma & the Sharp 65" LCD gets the 'Power Hog' award when on,
2. The Sharp 65" LCD & the older Mits 62" get that award when 'off',
3. The Samsung LED RPTVs' gets the 'Green' award for the lowest comsumption for per sq. inch (and for most bang for the buck),
4. Ten of the 12 highest 'Power Pigs' are Plasmas (no surprise),
5. The power consumption (and orginal cost) between RPTV and Flat Panel (both technologies) can be as high as 3x more,
6. The vast majority of the sets are 'Green' when off (standby),
7. Many 32" LCDs' draw as much power as 50 to 61" RPTVs' do,
8. RPTVs' have the best bang for the buck, both to buy and to run,
9. There is a 155 watt difference between 46/47" LCD panels,


There are additional links regarding power consumption, but I find this most interesting;

Notice that XBox360 & PlayStation 3 draw almost as much as a smaller TV (almost 200 watts).

One needs to remember that electricity draw = heat. Therefore air conditioners have to work harder to remove all that extra heat. Yes right now most places can use that heat to warm the house but it's not the most efficient way to heat a house.

"3. The Samsung LED RPTVs' gets the 'Green' award for the lowest comsumption for per sq. inch (and for most bang for the buck)"

Wow. Wonder what Al Gore has?

That's one more plus for those of us with the new Samsung LED RPTV's.....

Wow, I'm surprised how much difference there is between the panasonic 768p sets and the 1080p sets. Almost 70% increase in the 42" size. Almost 35% more in the 50" size.
Also pleasing to see how power efficient the newer Sammy DLPs are (I guess they have LED lighting?).

It was also surprising to see how energy efficient the Panasonic 42px75 was, using about as much energy as a similar sized LCD, but the rear projection sets blew everything away.

Well perhaps the Electric companies should campaign against most Plasma flat panels and LCD flat panels! ;-)

Don't worry--I'm sure the maroons in Congress will take care of that...considering new laws to require compact flourescents, one of the worst products out there from the health/safety angle.

JohnAV; You don't have to use the 'quote' function to make a reply especially if it is a long 'qoute'. According to your reply, you dont' seem to care about being 'green' or not.
