    I believe mailbox.org is all renewable, and I’m pretty sure it’s solar.

    But you need a massive battery bank to run stuff, batteries have a limited lifespan (especially the crap used in a UPS).

    It’s not cheap, you generally want to overbuild everything, and there are ongoing costs (hardware failures, batteries, etc).

    But it can be done. Just have to do the math for your max power draw, then how much uptime you need determines the size of your battery bank and number of panels (which is influenced by how much sun you get/how consistent it is). You need enough panels to run your system and charge batteries, given the limitations of sun availability.

    User retraining (imagine retraining 10,000 employees, and then the lost productivity you’d still have). Oh, and this assumes which shell, which distro?

    Excel, with tables.

    The thousands (millions?) of automated processes that export/import from Excel, and have done so for years.

    CNC systems that will only run on older versions of Windows, and for which the company no longer exists and there’s no reolacement. I once worked with CNC machines with controllers that ran on paper tape. They’re probably still running today.

    Ooh, here’s one - battery management on a laptop, that’s only adjustible from a command prompt in Linux.
