Meh.. Sensationalist title of article. The EU has motives to do this that are of interest to the general public. Television sets are used in many many households for many hours a day. Some people even leave them on the dumbest channels/programs during daytime to combat loneliness. Great for them. But if it draws 500W continuously because they bought a high-end TV "because I watch a lot of cable" (which may only offer you 720p or 1080p content), then that kind of stupidity cannot be argued with. People will do people things.
What an EU can do, is force manufacturers to make more efficient sets. Virtually all tech manufacturers are publically traded companies, which focus on capitalism and being that 1pt ahead of competition in some arbitrary benchmark. 8K is better than 4K, even though you would need to set <1m from the set with 20/20 vision to see any difference. 100Hz is better than 60Hz, even though that 100Hz is only with image interpolation techniques and if you turn it off, the set can only do 50Hz (which is worse), etc. It's of best interest to the public to keep manufacturers honest. It's to the best interest of the public to keep our country wide energy bill low.
There is no strict ban on the TV resolution or features. Only that the TV must offer some features at a decent performance/power e.g. efficiency ratio. We do this with cars, with houses, with whitegoods, so why not with electronics? Enforcement of regulations is to varying degrees - from a ban, to a tax increase, to an indication label that could suggest it costs a lot of money to run. That last indicator has been around for years, but if that's not enough, perhaps the other 2 measures are necessary.
Likewise, if we were to rephrase this headline to CPUs and GPUs, would be as much beraged? I think that was the generally received sentiment of last gen CPU/GPU hardware so far, and of Intel's last few generations in the past as well. In my opinion it's also a tech market that's gone crazy. Sure fierce competition is good for pricing, but other "side effects" may suffer in the end. It's not an honest way of making progress.
