I'm reading here and there that 'much' isn't always all that true. Be nice to have real figures.

Most of them a power supply that maxes out at 120w vs the pi4 with its 15w power supply. My guess is at idle usage would likely be around 30w so still a decent amount above a pi but still cheap to run 24x7.

Numbers are a bit off, for example an rpi4 will idle around 2.875 watts and peak around 6.4 watts ( https://linuxhint.com/power-consumption-raspberry-pi/ ) compare this with a NUC NUC6i5SYK that idles around 10 watts and peaks to around 50 watt ( https://www.legitreviews.com/intel-nuc-nuc6i5syk-skylake-mini-pc-review_181093/4 )

Let’s say you are at idle 80% of the time and peak for 20%, should be around 18 watts for the nuc and 3.58 watt for the rpi4. Typically if you are running some sort of service you will need to run this 24/7, and let’s take an example electrical cost (mine) of 24 cents per kwh for electrical with distribution fee. That’s around $3.11 per month or $37 per year for the NUC or 62 cents per month / or 7.44 per year for the rpi.

Now don’t get me wrong there are applications for both but with how many various systems I already have it’s not a insignificant difference depending on application.
