TV energy usage

Do the new HDTVs cost more or less to run than the older TVs? I have a 46 inch Sony WEGA, an old 27in RCA, two old 19in portables. I was wondering how they all compare in energy usage. I was also thinking about getting a 42in plasma and was wondering about how much one of them uses. Anybody have any insight?

If you're comparing old CRT type televisions (the old deep set) to an LCD or "thin screen", the energy usage is typically half or less.

The real estate savings is signifigant as well.

I've found it frustratingly hard to find out power usage of TV sets, for the different types (CRT, LCD, etc). I'm in no rush to replace my CRT, although there is a temptation to leave it behind the next time I move (it's heavy!). I think the LCD's are best on power, plasma's worst--but I could be wrong. I think my 27" (32?) runs around a 1kWhr for 8-10hours of run time.

This is basically correct. I don't have specifics, so I'm kinda pulling this out of my backside. First, you really need to compare TVs of the same size.

That said, Power usage goes about like this: CRT>plasma>DLP (bulb)>LCD>LED DLP. I'm not sure where the OLED TVs fall. I think they are pretty bloody efficient, but they are too expensive and the blues have a short lifespan right now.

I could be wrong, but I'm pretty sure that an LED engine DLP would be the most efficient size-for-size. The downside is, you can't hang them on a wall, being rear-projection. If I had to choose a new TV right now, it would be a 42 or 50 inch LED DLP. I like the picture brightness and quality of a DLP and don't need to hang it on a wall.

Also consider how long each type of TV lasts.

I would rather pay more to power an old CRT that will last 20+ years (or longer in my grandparents' case) than to re-buy TVs because LCDs don't seem to last more than a few years (in my friends' case).

CRTs are king for longevity at this point. Good luck finding a 50" HD CRT, though...

DLPs are easily repaired, LCDs are too. Plasmas are more-or-less irreparable.

There's a widely-regarded gadget you can get called a Kill-a-watt that will measure appliance energy usage. It's priced $20 on Amazon.

You have a 10 foot LCD TV? That's fricking huge! Is it installed in a stadium?
