Can someone smarter than me please explain…

Frankly, I think there should be a mix of BEV and ICE vehicles used. There are places each shine.
It would make more sense to start upgrading structures to gain and lose less energy, and stop burning fossil fuels for residential and light commercial space heating, leaving those fuels for industrial and heavy commercial use, or vehicles where the energy density is needed.
The infrastructure is in place to keep ICE vehicles going for quite a while.
It's far easier to up the efficiency of static structures that exist, and are to be built, and keep the limited and "dirty" fuels in ships, aircraft, and ground vehicles.

Plenty of uses for current electric vehicles, especially smaller commuter cars and crossovers, with existing technology.
If you could get one, and my wife would give up her Grand Cherokee WK2 (and we didn't need it for towing now since I sold my truck) she could drive a RAV4 prime and have all the features she wants and easily cover her regular commutes and normal weekend travel.

I totally agree. My wife primarily drives our Outlander PHEV to and from work, works great for that as the distance aligns well with the battery range in this vehicle.

Commodity prices are going to get much more expense and soon.
How much will it cost to replace a 7 year old Tesla battery when someone goes looking for a used EV?
$20,000 would be hard to come up with for most people for a battery.

Current BEV batteries have a life around 15 to 20 years.

no lie about prices going up

Average new Car/LtTruck (combined) sales price
2018 $37,414 . 2019 $38,003. 2020 $39,251 2021 $45,458. 2022 $48,692

Current BEV batteries have a life around 15 to 20 years.

And that’s just the primary life as a means of energy storage for the vehicle. Battery packs at 15-20 years old are still suitable for emergency power backups or off grid power storage solutions.

None of the EV studies I've seen include the cost of increasing the (nuclear) power supply by 10X or the cost of a distribution system needed to plug 300,000,000 EV vehicles in.

Why would we have to increase power supply by 10X for EVs? The average Florida home uses ~37kWh/day. A EV driven 30 miles/day would use about 10kWh. Even if you had 3 EVs commuting every day, that wouldn't even 2X your needed power, let alone 10X, and the refineries won't be using the electricity necessary to refine the gasoline you used, either.

Either way, you're talking about cost, but replying to a post amount emissions. And furthermore, the cost of building and maintaining power systems is covered by the cost of electricity, like it is now. If people are using more electricity, utilities build more production because they're now getting paid more money from higher usage. This doesn't rebut the claim that EV lifetime emissions are better than gas/diesel.

Model Y battery is like $13k, now. Chances are it goes down, not up. Also, most won't be replacing a 7-year-old battery if the warranty goes to 8 years/100k miles. Most batteries will last substantially longer than that, and 15 year from now, if you have to replace it (and the car's useful life isn't over anyway), the cost will probably be lower, too.

To replace electricity that is CURRENTLY generated by fossil fuels there needs to be 10X more electricity generated from renewable sources.

Additional power will be needed:
- to replace fossil fuels used for other power generation
- to stop developing nations from using fossil fuels
- to power machines for carbon capture in the airline & agriculture industries
- for carbon capture needed to lower CO emissions to a level (30 years ago) that will stop climate change

I suggest you talk to some people that have looked at installing EV chargers in existing buildings/homes.

I read a paper a couple years ago which addressed this... And it said the change to air conditioning in peoples homes 70 years ago, was a much bigger change to the power grid, compared to if everyone got an EV now. And, that change went perfectly smoothly 70 years ago. I'm sure the utilities would manage today, too. That's their business. Don't worry about it, and leave it to them. They'll make more money. We'll all have a better power grid. Everyone wins.

The place BEVs have always had a perfect (though largely ignored) niche is very tiny urban vehicles... cheap and very efficient. We just need to repurpose roads and infrastructure to make them safe to use.

Did the study factor in the 6 layers of government, the 10 consultinting firms and the 12 engineerings that are needed for 10 people to go to work?

The utilities today can't handle a good windstorm or an ice storm, good luck with the rest.

Yeah, our world is not efficient. Privatization and deregulation hasn't helped anyone but the rich. Back when this all happened we were a much more socialist nation, and things got done.
But this is the world we live in now. We can sit around and complain and stagnate... Or go out and keep pushing for progress. Buy that electric car. Upgrade that electric service to your home. Just like your grandpa or great grandpa did when he got his fancy new AC.
