“coal-charged, battery-powered vehicle.”

Such a boomer skree at least be accurate the US grid is dominated by natural gas at 42%, coal is less than 16% coal, nuclear is 18% and all forms of renewables is 22%. This is actual megawatt hours delivered and consumed not installed capacity. So your coal powered is flat out wrong. Factually an EV is 40% nuclear and renewable charge charged with zero air emissions from those sources. Or 42% natural gas charged with 65% combined cycle gas turbine efficiency and near zero air emissions from modern gas turbines. Gas turbines being two orders of magnitude cleaner than diesels even with SCR and particulate filters. Add in the demonstrable fact that 65% eff turbine plus less than 5% grid transport losses over 200km to the plug and 8% loss plug to pack. The well to wheel of an EV is one third the BTU per mile vs petrol on a LHV btu for btu basis when compared to natural gas turbine electricity. So you burn one third less fuel why because no ICE anywhere gets close to 65% thermal efficiency you can throw away 8% and 5% and still be above the 25% eff of an ICE driving wheels. Google scholar is full of peer reviewed facts on this very subject.

This is all moot when you can charge an EV off solar panels on the roof above it. Mine is fully charged every day off the system of panels on the steel building above it. Only on road trips will it ever see a tesla supercharger. It cost me zero cents per mile when solar charged the system payed for itself already. And is turning a nice profit as Texas rates hit 20 cents per kwh it hurts to not sell the power at those kinda rates or higher vs charging during the day. So really the opportunity cost of not selling the power vs using it myself is the true cost. I also have battery banks for prepper reasons I actually charge those overnight at 4 cents per kwh and then sell the solar during the day for 50 to 90 cents. So my real operating cost for the EV is those night kWh offsetting the day ones. And the cycle life of the battery banks which are on loan while I torture test them for a friends solar company. I cycle them 80% hard and fast during peak hours then charge off peak for next to nothing largely using cheap night time wind at 3 to 5 cents per kwh.

Here is one looking at trains which are much more efficient than automobiles a diesel is only 26% WTW that’s with an ICE twice as efficient as a light duty petrol motor.

Forget just the U.S. grid. The world runs on coal.

As for your boomer screed, we'll tax you to make sure everyone gets a house with a roof and tax you again to subsidize their solar panels. We'll also force electrical generation companies to run at a loss to buy back power from your new solar friends at the retail rate instead of cost, just like they're already forced to do for you.

Your solar system never paid for itself - the taxpayer and other electrical consumers subsidized it.
