Many areas in the US still don’t. I remember living on a farm as a child, circa 1998, and our neighbors had no power or running water. It wasn’t lack of wanting it, “the money just ran out.” This was the mountains of Virginia, near Roanoke.
In the scale of the US, that's a blatantly false statement.
It's < 50,000 people out of 330 million. Or less than 0.02% of the population. Most of that is because they're living in quite isolated locations far from any population.
The figure is so high the WorldBank lists the US at 100% access to electricity with all the other affluent nations. Brazil is at 99.8% for reference, Vietnam is 99.4%, India is 97.8%.
I wasn’t saying it was whole chunks of the country. Just that there are many places, not necessarily in the same place and not necessarily enough for anyone to care about. The latter kind of being the problem…
