It's a weird thing so say that a higher electricity consumption equals to "vastly higher living standards" when the higher consumption might just be in part because of badly insulated homes.
I'm old and by my family's standards 65" diagonal would be questionable at best, so I checked in the vicinity of 48", 43" and 50" only gets you down to 120-5 watts. Add probably not very many watts for whatever's supplying the signal and it doesn't sound like a big deal, although of course everything adds up.
