do you have any data to support that?

For a rough first pass, I would just look at monetary cost. I was going to dispute OP's comment. Thinking of my old Athlon server that used around $20 of electricity per month, cost about $600 new IIRC (mobo+CPU+RAM), and ran for more than a decade ($2400). But there has been a concerted effort to lower device power consumption, and my current 5700G server (two generations later) uses only around $5/mo of electricity.

Sure. Two good sources are: 1.

  What about for desktops? Servers operating at capacity? GPUs?

  now a fairphone uses 2W during use, a dual-socket server 100W in idle (!). Assuming emissions scale with weight, I'd say for a typical server, this is very different. Still, I agree with you: design for efficiency and then mend and use efficiently.
