Easily available info shows that New Orleans has over 50 public chargers. They are not hard to find and use.
And why do people keep saying "own" a home? Are renters not allowed to use electricity?
We frequent New Orleans regularly, the only "older city" part with a real lack of off-street parking is the French Quarter and the garden district. Most everywhere else there is suburban. That said, Louisiana does have the lowest number of chargers per-capita of all the states...
Well, they may have more public chargers.
But I"m not sure where in NOLA you are going, but a LOT of the city does not have off street parking....most of it doesn't like around garden district...Irish Channel, anywhere much off St. Charles....sorry I don't think you know NOLA like you think you do.
I've lived here for about 30. years....Newer areas like maybe near the lake have offstreet more...and a bit more once you get into the suburbs, but in NOLA proper, city limits....I'd say most places do not have offstreet...was rare in mid city and bayou st John.
And what are you going to do in that case? Lay down extension cords from your house to the street (if you are lucky enough to actually park in front of your own place?).
And if you rent a house...you are not generally able to get the landlord to let you install new power and wiring to set up chargers....
And what site did you use? Last time I looked and I'll grant it was a bit ago...even the chargers shown, many were marked "private".
