    Federal funds would be available to help, as this is also a public safety, health and security issue. When the poles fall, they not only cut off power and utilities, they isolate communities.

      I don't know about that. As far as I know the only issue with overhead wires is that they use the air as the insulator so the higher the voltage, the further apart the wires are kept. Magnetic fields are a function of current, not voltage. Higher voltages means lower current for the same power transfer.

      But when you put the wires in underground, you have to use something else as an insulator - and it will eventually break down. And it's harder to inspect and replace.
