Perhaps the newer models consume that much (under load), but the older ones are very power efficient - back in the day they ran Windows 8 and only consumed 4.6W @ idle (this is actually the same one I have, except I run HA on it which is probably much more power efficient than Windows 8 would be).
Realistically, for something like this, you probably don’t want to exclusively use the full load numbers to calculate power consumption, rather you want to use the idle+load numbers for your specific use case. Home Assistant barely uses any power even over time (I unfortunately misplaced my kill-a-watt or I’d measure it for you), and the NUC barely feels warm.
Nonetheless, you can disable a bunch of the GPU stuff in the BIOS if you’re concerned about power consumption. The article I linked above explains the settings a bit. These were meant to be the middle ground between a thin client and full PC, so it wouldn’t be surprising if their maximum wattage & TDP was much higher than a Pi; but that doesn’t necessarily mean a higher power bill or more heat.
Lastly, I mostly meant that this would be a good alternative to the device in the article, which would need a beefier power supply than the NUC. This shop listing says that its TDP is 60W, so just looking at raw numbers the NUC runs much cooler.
I googled a cheap Intel NUC and saw power consumption numbers of 15w to 40w. Thats quite a bit of juice (and heat) for small applications.
