gollark: I see.
gollark: Also, I may be wrong but I think a lot of generation things are more efficient at larger scales rather than smaller ones.
gollark: I'm not sure that's a good thing, though - if you have more interconnected locations, they can load-balance in case of high demand.
gollark: Isn't it already *fairly* decentralized? Different regions have their own grids, sort of thing?
gollark: Personally, I don't think anything which heavily centralizes power, i.e. dictators or centrally planned economies, is a good idea.
