AWS exceeded 50% renewable energy usage for 2018. My house is powered by gas.

"I didn't have any quantitative estimates then, and still don't now. However, it's likely that a world in which there is one server per household or per street would be more electrically efficient than the current world of billionaire cloud servers."

My neighbors are powered by gas too. The only way this would work is if we all also bought solar as the author suggests, however encouraging your average homeowner to not only run a home server but also invest in solar for it is a non-starter.

The argument is a little shaky, but I can see it. In a datacenter, heat is just wasted energy that requires more energy to cool. Running a server is not the most efficient way to heat a home, but at least the heat isn't just waste.

Also I suspect that a home server could just sleep the CPU a fair % of the time. On top of that, you don't need to run a billing system that charges different users for various things.
