"Presently" is the key word.
Utilities presently typically charge basic connection fees under $20 / month.
But utilities scared of solar are moving towards charging between $50 and $1

The big picture for the utilities is that people with solar buy substantially
less electricity, which in turn means the utilities

The more I think about it, the more I think that the grid's days are numbered.
No, not that it'll go away entirely -- at least, not for a lifetime or more.
But, rather, that, in ten to twenty years, people will be as comfortable not
having a grid connection as they are today not having a landlin

Of course not.
Just as EVs aren't suitable for everybody, either.
But exceptions, even if numerous, don't invalidate the usage for huge swaths of
the population.
Obviously, if you live in a 20-story apartment com

Again, just as with EVs, it's not going to be an universal solution. But, again
again, even a partial solution is going to make sense for lots of folks.
Somebody who really does need a diesel pickup to haul stuff around on a regular
basis may still be a perfect candidate for an EV for a daily co
