A report by the Natural Resources Defense Council (NRDC) in the US finds Ultra HD 4K TVs consume up to 30 per cent more energy than existing high-definition models.

The European Environment Bureau (EEB) is warning shoppers on Black Friday (November 27th) that while some 4K TVs may appear a bargain, it could lock them into higher electricity bills over the long term.

EEB spokesman Jack Hunter says: "TVs were already the energy hog among entertainment gadgets. Now bargain hunters need to keep an even closer eye on energy costs, not just price tags. It's clear some UHD models perform far better than others."

The NRDC report says Ultra HD 4K TVs "could add $1bn to viewers' annual electricity bills".

Among the TVs tested, the NRDC found wide discrepancies with "some sets consuming more than 2.5 times as much as others with the same screen size". Overall, says the report, "we conclude that today's average 4K TV uses approximately 30 per cent more energy than an equal-size HDTV".

CCFL LCD didn't come near similar sized, hefty chunk of quality, power-hungry sets that were at one time Kuros, and later Pana PDP, Then slim LED-LCDs really cut usage down again, even vs. also slink looking proper Plasmas- Top Pannys, some Sammys.

I would imagine its a lesser gap but a modern Plasma would still use more power, inherently, than UHD TVs. (imo) Didnt bother researching figures as I'm sure there was no need. Smile

Also shouldn't that be a picture of a UHD Samsung under the headline after all the power the 5 star & award sets used up, that were provided...relentlessly. Pardon Yahoo
