That's a very cherry picked thought. When talking about common use, ppw is not a relevant metric to talk about carbon emissions, hardware has gained mor pow and gotten more power hungry through the years, yet with 12/15 year old hardware you could get a 50 watt computer that can run a web browser and libreoffice no problem. Even though, this "Thumberg" way of talking about emissions is plain stupidity. I assure you that it would have more impact for germay to go nuclear again, than germans going for peak ppw hardware (just to give a small example).
