Energy consumption: SolydX vs SolydK

Does SolydX consume sensibly less energy than SolydK?
Do you have some data about it?

How would you suggest to measure this?

I think there are only very few people that use both systems on the same hardware. And even then organizing similar conditions for measuring would be nearly impossible.

Maybe you could do a test with 2 standard installed systems, one SolydK and one the other. Just let them boot with a full battery, then don't do anything, just let the computer sit there waiting for the power system to shut it down because the battery has reached almost 0%.
When you start using programs it is a matter of when do you start them, how long are you using them, what do you do with them, difficult to find identical situations.
When you let the computer just stand there and measure the time till it shuts down, of course with identical settings for power, for no screensaver, for no shutdown after so many minutes, then you will have a value. If it is any good is still doubtful but at least you have something.

Something that will take considerably less time is to run some video in a loop, no screen shutdown, no hibernate, etc.

But the question will still remain whether this result will be useful. I don't know.

For those with computers powered by a mains plug just fit a plug which tells you how much current is being consumed.
Some uk utilities provide 'smart meters' which effectively do this for the total supply consumption.

Since XFCE uses less resources, is it wrong to think that it consumes less energy as well?

No, but I think only by a very small margin. But if KDE needs considerably more time for each operation (so that you have to wait for it to finish) then SolydX will consume less time and subsequently less energy.

the cpu power usage might different but the system still using almost same amount energy for everything else (i.e: screen, wifi, fan, boards, etc). in the end the total power usage usually not much different.

btw, if you're using a laptop, you can use powertop to roughly calculate the power usage. though, it doesn't measure screen and other external hardwares.
