What I expect to happen is that somebody will make some smart power distribution hub that intelligently charges multiple vehicles and has an app interface to customize settings.
There are several companies developing a lot of cool EV tech, smart charge hubs are already being worked on. I personally think the coolest is being able to use EV batteries as storage for household consumption, grid stabilization, exporting during peak demand when prices are high, etc.

the average home is not setup to have something like this, and will require a couple thousand dollars to get set up.
There are almost 300 million cars registered in the US, more than there are people.
even if you just assumed half of them were regularly in use, that's an extra 2.6 BILLION Kilowatts being used to charge them. Just for some comparison sake on what 2.6B KW of electricity is, NYC uses about 11 million KW of electricity a day, so you're talking about adding the equivalent of 236 New York City's to our electrical infastructure.
So sure, it's not insurmountable.
Again. These are not insurmountable engineering problems. The only real constraint is lithium but there’s other materials on the horizon that can be used for home batteries. Also, by constraint I don’t mean that we will run out of lithium. There’s plenty of it. It’ll just that big mining projects need to happen in order to scale out and that will take time.
Solar roofs will become a thing. If you’re saving $30k over 20 years then those home infrastructure investments make more sense once prices get low enough.

This may have been covered, but where is all of this electricity going to come from?

Seriously though, increased generation deployment. More of all types of generation are being deployed daily. Decreased gas consumption by vehicles will get diverted to larger and more efficient generators. Deployment at the point of consumption (solar), and a continued expansion of the grid with balancing tech from increased deployment of storage.
Anyone who thinks in 10 years the switch will flip and everything will be EV is wrong. Estimates say that if we stopped producing fossil fuel vehicles tomorrow it would take 20 years to hit 50% EVs on the road. So basically, 30-40 years is plenty of time to keep doing what we're already doing.

It should come from Nuclear energy but it won't.

So, basically in 10 years we are going to power this movement with wind and solar. Bold strategy.

Wasn't directed at you specifically. However, if we are getting rid of fossil fuels and nuclear is out...what does that leave us with?

Got it. Anyone saying we should get rid of fossil fuels is a dumbass. I do think directing them towards more efficient use can help. And Nuclear absolutely needs to be brought back into the equation. Its not the answer to all the problems, but its provides steady and reliable power. I see it as a solid base to build demand surges on. We really need a more balanced generation approach with fast response storage and increased diversification or type and location of generation for stability.

Obviously if we were to go all electric, 2 of these at $10k would be ideal, but only 1 is necessary and can be added for much less than a couple thousand dollars.

Mixed sources but a lot of it could come from home solar panels. Battery packs installed in homes and fleet vehicles can store the energy.
When did you all become such pussies? You don’t think we can double our energy output over the next 20 or 30 years? Don’t you like the idea of living off the grid?

Sure we can. Drill...baby...drill.

NEMA 14-50 is a fairly standard 220v outlet. But imagine 2 or 3 of those charging at once. It would occasionally happen if you have an all EV fleet at home.
Would else would be needed besides those additional outlets?

It'll be interesting to see how they hold up to high winds, hail ,etc.
Supposedly the Tesla shingles hold up to hail and some wind, but I don't think they are tested for hurricane-prone areas.
I would do an array out in the yard away from the house just to make potential repairs easier, but very few neighbors are going to be okay with those ugly things next door.

I actually have a copy of the IE report on them. I'm more interested to see real world results at scale. They should definitely hold up better than normal modules for wind, which actually don't perform as bad as some people think in hurricane force winds.

I have no clue how all the electrical stuff works, if you will. I know it only costs me roughly $20/month to charge at home, so that would lead me to believe it's really not using that much additional electricity so just a complete guess that adding a 2nd would also not be a huge deal. Obviously I'm just talking about 1 household, not if everyone household is charging multiple vehicles.
Would be interested to hear insight from someone who knows a lot more than I do about these things.

The $10,000 batteries that have to be replaced every 80-100k for electric vehicles is the real issue.

folks I know with them in Chicago almost never produce enough juice to power the home and have to rely on the electrical grid. Louisiana has slightly longer days, so it may be different.
It’s certainly better down here, but you won’t be able to power your air conditioners with solar arrays. You could keep lights, and maybe a refrigerator going.

You don’t need 100 amps. That’s the maximum rate you can charge the biggest Tesla. You don’t need to charge at the maximum rate. That’s the rate you would use if you were traveling and pulled over to charge.
At home, your car is generally in your garage for at least 10 hours. You can charge with a regular outlet, from 0 to fully charged in about 48 hours. But there are products available that you put in your garage, plugged into a normal 20 amp outlet, that have batteries. Even when your car is gone it charges. When you plug your car in it charges at 70 or 80 amps in 2 or 3 hours.
My suggestion is to put two (or as many cars as you want to charge simultaneously) 30 amp 240 volt receptacles. I would also install a 1 1/2” conduit under the slab from the floor in front of the receptacle to a spot under the hood of your parked car. In this conduit, I would install the charge cable so that it would not present a tripping hazard. Using this approach, and a $500 Juice Box, you would not greatly increase your construction cost.
Keep in mind that in 15 years you will probably not own a car at all. By that time, driverless cars will be obtainable via ride share, in every shape and size, cheap and fast.
