Universities have been running Linux since the very early versions. Slackware was pretty common back in the 90s and 2000s and universities had labs full of them not least because there weren’t really laptops so they had to have enough machines for all the students. Universities have been heavily involved in the development of unix from its inception and a lot of the tools were initially written by university professors.
The laws of physics mean that no matter what we do with carbon capture it is never going to be cheaper and less energy to emit it and then capture it again. This is a foolish endeavour the focus should be on the green transition with Wind, Solar and Storage combined with ensuring infrastructure is there for Electric Vehicle transition. This is the sort of investment the fossil fuel wants governments to make that will have no impact and allow them to continue to emit.
