When is a comment a question ? Will change to what ?

The transmission and distribution systems must be built out to accommodate EVs, as has already been discussed.
I believe Georgia and probably Alabama will be in good shape for this. Other places? Well... some places can't even keep the lights on 24/7/365, even now.





Is the problem that the neighborhood lines cannot support the increased load that's demanded by all the devices in modern homes along with EV chargers? That's the "last mile" I guess we're talking about, like going from a telephone local loop to the home.

So... everything beyond the substation basically?

That's because there are more needed and, major brand gasoline stations are a fading thing and have been for decades, with convenient store non brand stations being more common than Shell-Exxon-Exxon-Mobil-Texaco-Chevron etc.

1. every charging station only have a few spaces @ best.
And can't charge as many cars as just 1 gas pump per hour and nearly no gas station only has 1 pump.

Wawa, Royal Crown, and many others have 10 to 20 or even more dual pumps that Fill 2 cars for each unit and in minutes.

Again, Fast charge battery only gets you to 80% charge and takes way longer then buying gas and better hope that gets you to next Fast Charge or destination and that has any charging.

People run out of gas & often then call AAA or anyone else can deliver 1 5 or more gallons and be gone in minutes to maybe hour depend just where you are.
No charge them most areas the Only Option is to Tow and cost you Big $ every time and wait for the tow then more time to charge.

And if you/others think Gas stations are going away... Why does Wawa, Royal Crown, and many others are Building New High Volume Stations w/ a lot of Dual Pumps every year? Because They and the banks paying for this know is not going away in Decades.

In many areas is these companies that are "killing" smaller stations including some brand stores own by X co or more likely owned or operated by a Franchisee of X.
Plus more areas are forcing stations to install new tanks and more forcing small station to close because not enough sales. Decades ago in many places you can't bury gas/oil tanks w/o extras to stop leakage etc. And can't just remove old tanks & related w/o very costly cleanup. Why many stations get "abandoned" by owners and sit closed often for many years. Real abandon or just cheaper to pay taxes etc on closed station and right off for other taxes vs replacing old tanks.

Shell is always at least $ .15 per gallon more expensive then any other brand in our area.

Yes and more. Read my post above again.

Example: I have 150A Service only because PO had an electric fire required a new load panel & related equipment & wiring. And remember you only allow ~ 80% load on X amp Service.
Many others in this area only have 100A service or less because have Gas Service for Heating, cooking, and other things that would need way more power if all electric. You can't install Level 2 charger pulling 30 to 50+ amps in homes like that. Not sure even 150A Service can take L2 @ 50+ amps in many homes either.
So if you want L2 charging then have to Upgrade the Service too and cost hundreds to thousands more over the cost to install the charger. That even if you get Permits from City etc to do that because any or all parts from you home to the substation may not allow more people to have 200A Service.

Say you have 150A to 200A Service on even a small home but no gas/oil to heat etc.
Just a "basic" E-range for cooking draws 40+ Amps if fully on. E water heater pulls 30+A. Heating can easy pull 100+A.
(And Air/Air Heatpumps often have "backup" heating On a lot in many places & many are Resistive Electric heaters.) Then try to add L2 charging pulling 30 to 50+ amps for Many Hours... Can easy violate the "80% rule" and cause huge problems w/ Insurance Co and more. Power Co in many areas now know exact amps draw in a home because of Smart Meters and flag any pulling too much for Service to them.

Thank you for your insight theogre !

By far the biggest limiting factor with EVs is range...Around town, short commutes, they work great. Any long distance trips are basically off the board.

I did a trip looping around Lake Powell in Southern Utah (I highly recommend this trip).....7-8 hours driving each day- approx' 350-600 miles each (Travel) day...No EV could accomplish that. We need new and much-improved batteries...and more efficient motors, etc.

Think of what technology for IC engine was like just 50 years ago...We had been developing ICs (In a proper COMPETITIVE market) for 75+ years....yet the engines back in the late 60s and early 70s were not very good- especially efficiency...

Back in 1980, a friend and I were talking- he stated "I wish I was born earlier- So I could have >>Driven<< through the muscle-car era!"

I told him, "We will have more powerful cars soon"

And he replied "Smog controls, fuel economy standards....there is no way to have powerful engines ever again"

I had just read an article on smog control/clean-burning engines, so I replied, "How do you get better fuel economy- make the engine more efficient. How do you make the engine more powerful- make the engine more efficient. And how do you make the engine burn cleaner....Make the engine more EFFICIENT!"

Two years later (1982) the Mustang came out with the high-output 302 V8 (A "staggering" 157 hp) The HP started going up then and has continued.

Now we have 400 hp engines in "Cheap" cars.....Un-freaking believable! (Go back to 1980 and try telling yourself that in 40 years 400 hp will be common in production cars)
