Because it's "backup" hardware. Like a lot of insurance, it's often just a false sense of security. It would be interesting to run a datacenter completely on batteries that are charged from solar + the grid + gas generators. You could run the generators at optimal power output and use them daily. The batteries required for ~24-48 hours might still be too expensive to make this possible. Maybe some kind of super low power datacenter could pull this off. One day it shall be mine.
