According to the internet a CRT TV used to use about 100W, while a big LCD TV can use more.
Regarding desktops, don't forget that these days we have many more electronic device in a home. Smart speakers, home media devices, consoles, etc, etc. Electronics probably use, in aggregate 5-10x what the old family PC used to use, I'd imagine.

- rootusrootus 3y agoThe CRT TVs back in the 70s and 80s were pigs. Not 150W, more like 300W and sometimes more. It would take some work to make a modern LCD with similar consumption. Even when plasma was all the rage, it wasn't that bad.
