Battery based electric vehicles of today and tomorrow.

My mother drives 2000 miles per year, and probably never gets more than 15 miles from the house. A reasonably priced EV would be perfect for somebody like her. Unfortunately, $69500 is not reasonably priced.

That’s about $170 a year with $2.50 per gallon gasoline and 30mpg. The battery replacement will be far more.

My point is that EV makes sense, you can close your coal powerplant and replace it with solar panels and all the EV will be a lot more environmental friendly over night, what other cars can do that?

Just not an overnight charge.

So charge in the daytime. Solved that for you. That wasn't so hard!

Well, a EV dont run on coal, its really the most multifuel cars that exist. And its better to move pollution away from the street.

I suspect that in the overall picture you are simply moving the pollution issue to another location and since in every stage of conversion efficiency is lost.
Heck even a fair % of electricity is wasted in the transmission lines.
(If a person was to run a line parallel to a transmission he'd capture 'free' electricity but that is illegal.)

Next will come the disposal issue of those EV batteries.

Leave no trace of pollution is not possible with our machines it seems.
No used motor oil is an EV plus in my case. Wasting 7-8 gallon of gas out of every 10 gallons that I pay for as unwanted heat and tailpipe emissions finally register on my old brain

Of course in many cases you are moving it, but still better than most alternatives. And it's a question of view, if you only sees it as a transport solution or look at in the perspective of redusing emissions and still drive a car. It doesn't matter how clean an ICE is if thousands and thousands move slowly pass you, your kids and you house. Nobody has shown any positive effect of breathing exhaust.

That's not exactly accurate. Sure, EV does not directly run on coal. Indirectly, it absolutely does. That is the point I was making.

It doesn't matter. A Tesla Model 3 "running on 100% coal" is emissions-equivalent to a 40 MPG gasoline automobile. And gasoline automobile can not run on coal, no way, no how. But there are at least a dozen ways to generate electricity, the EV has no care as to the source.

How is it using coal to power an EV is bad, but perfectly fine to run your home, shop, street lights, and farm?

Your LEAF has motor oil. Tesla specifies 4 year drain intervals.

You do not waste 7-8 gallons of every 10 gallons of gasoline unless your trip was for naught. One chooses to use gasoline because gasoline gets the job done for less cost and effort than the alternative, of say, a horse. You could have made the effort to drive your LEAF home, researching charge stations every 60 miles or so, but you chose to bring truck and trailer. The gasoline consumed was not wasted, it was a conscious decision the gasoline was worth less than your time and effort. It doesn't matter how much "waste" heat was generated. The labor and resources used to produce the gasoline was less than your labor and resources (effort to drive the LEAF) which were conserved by burning the gasoline.

Speaking of waste heat, every kWh you put in your LEAF is converted to heat. What do you think happens to air the vehicle has to push out of the way? It gets heated. All motion eventually becomes heat. The resistance that requires power to move a vehicle is generating heat by friction.

Less than 5%. Transmission lines are delightfully efficient.

The 2nd wire has to be very close. Is easier to just throw a wire over the transmission lines. Transmission lines are not insulated.

Not a problem. Materials are dump-safe, unlike NiCAD or lead-acid. Furthermore a lithium battery with half capacity isn't a good EV battery but it still works and is perfectly good for stationary use. And after that it is a rich source of exactly the materials needed to make new batteries. Easier and purer than raw ore. Greedy capitalists will recycle batteries because for profit without even being told they have to. Just as is happening with lead-acid batteries.
