There's interesting sociological analysis and commentary here but I felt the maps and numbers part was ironically just 'small data' and stats for their own sake.
Why doesn't Amazon buy a county similar to what Walt Disney did in Florida.
by concentrating the load into a single location like that, you would likely overload the transmission system at that location and trigger a ton of system upgrades. so they would likely need to build their own generation and still probably upgrade lines if they just took over a county.
