In my opinion, Europe is behind on the US technology wise, but as far as the electricity system goes, the US is pretty outdated. The plugs and sockets for example are hell, providing no stability at all. In most US cities, the utility poles are still made of wood and a lot of main electrical connections between towns use these old wooden poles as their only support. A simple storm could easily cause power outages…
This picture of a utility pole with transformer mess was taken in Butte (No, with an “e” and no it does not originate from…, it’s French for “small hill”) , Montana and these can still be seen everywhere across the country.
