If you are running the machine anyway to do other tasks like backing up and running Jellyfish then it might be worth it.

How did you get to 150kg of CO2 per user? I'm going to assume you mean each person has one instance rather than sharing an instance like a family would. So thats 375Kwh per year, which works out as drawing 42W. That seems rather high to me.

I'm hoping to try and run this on my Pi4 which idles at under 1W. You could run on a Macbook M1 which only under heavy load conumes 42W, but I doubt this is going to need consistent heavy load: https://www.anandtech.com/show/17024/apple-m1-max-performanc...

My personal server is a 9900K with 64GB ram and normally around 35 various docker containers running on it. It's very rare to see it ever above 10% CPU utilization.

For example, I host between 5-10 minecraft servers for my kids, but they sleep while the kids aren't playing on them and only spool up when a link is requested.

A properly configured Linux box would barely need a trickle of energy when nothing is demanding its resources, so I'd guess that the estimates are likely a bit on the high side.

I do this same thing with 1 server. How fo you handle requests? I used a lambda to fire up an ec2 instance but just moved to locally served.

Yes, I assumed 1 user per server. If a family shares the server, then you can divide by the number of family members.

The link I shared has the details of the calculation. The calculation assumes 50% CPU load which is most likely too high for this use case.
