How often do you actually reboot your machine? My office compile box is showing 17 days uptime, and that's quite low (I think I did an update). Optimizing a few seconds off of something you seldom do isn't that useful. (Not that I haven't been guilty of that, again and again and again and...)

Given that you are supposed to work 8 hours and not work 16 your office box should not heat the planet 66% unnecessarily. Disclaimer: I don't meet the 8 hour goal and the unattended boot of my office machine setup has been incomplete for 5 years... Edit: We do also nightly builds, but they take between 5 minutes and less than 3 hours.

  Even if you almost never reboot your box it can go into deep sleep when it's not used. It doesn't "heat the planet" significantly when doing so. Actually it would be interesting to calculate whether frequent reboots don't use more energy in sum than putting the machine into sleep. Does anybody have numbers on that?

    Typical boot is somewhere.. okay, lets take 30 seconds for all boot shenanigans. Okay, 1 min for ease of count. That's 0.0694444444444444% a day. Doubt it. Even monster servers (like 4CPU and TBs of RAM) boot up in 10 minutes and that's only 0.69% of the day. Modern systems don't gobble all up all available power at the startup and pretty quickly go to a power controlled mode. Sure if you have some monster with a dozens of HDDs then there could be some nuances, but at that point you surely don't reboot often anyway

    In mobile phones similar optimizations where done at least when battery sizes were well below 1000mAh. I think race to sleep was very competitive. So you run at full power for a short time and then you go to a deep sleep mode. Discaimer: Have not worked with mobile phones for 10+ years.

  I wish we could heat the entire Planet with 40-50 Watts/hour

    I wish there were only 1 computer on the planet?

      I wish only computers heated the Earth. Some kind of ideas are stupid and we must go back to reasoning about real problems, not fictional problems. A computer that stays in sleep most of the times is the last problem we have in modern societies. Meanwhile people set their home temperature at 30C in winter (when it's 10-15C outside) and the AC at 16C during summer (when it's 28-30C outside) maybe just don't?

At the time I was dual booting to windows, and had just gotten my first ssd. I was a bit obsessed with boot time.
