US power distribution is way more distributed than in Europe, in which everything is planned and centralized.

In the US there are transformers everywhere, you can see a house and a small transformer nearby.

In Europe they have this big monsters that cost several million dollars and require a train to move.

In Europe transformers in the city use to be underground and you won't see anything but a blackout of power.

It happened in Madrid some years ago.

Old transformers are very toxic as mineral oil with aromatic rings is burned,which is carcinogenic. New transformers use Hexafluoride SHF6 that are smaller, innocuous and easier to control.

But it cost a lot of money to update your infrastructure.

New York also has experimental superconductor lines.
