unless....the direct current electricity we use today only won out because of politics when the alternating current electricity Nikola Tesla envisioned was truly the better innovation

Where is DC used for power transmission? As far as I know it’s ACTUALLY exclusively.

HVDC for long distance transmission lines is totally normal for the last 20 years.

Local distribution, though, is AC everywhere AFAIK

Interesting. I imagine the AC use on local distribution has to do with the ease in creating relevant voltages for the application, eg. 12kV for short isolated runs to 6.5kV to pole transformers to 480/240/120 here in the US using smaller wires for the same power yield. I suppose HVDC for long isolated transmission would be more efficient, fewer inductive loses is my guess?
