Back when Edison and Westinghouse powered two different cities, one with AC (Westinghouse) and DC (Edison) they found out that AC was the more practical current to use because the DC would lose its value the farther away it was from the Generator.

Read VillageTinkers reply, there are a few, long distance, and we have at least one in the NE from Canada, the substation is in the town next to us, and the transmission corridor is adjacent to my parents' house. and its confirmed DC from Canada from the engineers in my company who built the receiving end distribution station of the Quebec hydro electric supply into the NE.
so its not a black and white
There are no DC power lines. And I tried to connect with the transmission engineers in my company on Friday, but they were out of the office for the day.
but i still love the discussions here as its a perfect display of human behavior and biases in action.
