We run private AI infrastructure in the Pacific Northwest — dedicated GPUs for teams who can't send their data to a public API, along with the engineering to get open models deployed and running on them. A single machine draws about fifteen kilowatts around the clock, roughly a dozen households, which is how a joke about the weather turned into a serious question about where electricity comes from. This map is what became of the tool that gave us the name.
Scores combine live atmospheric data with the sun’s true position at each location. A hundred means nothing is getting in the way. When there is no direct sun anywhere, the list ranks by overall daylight instead.
