They are assuming coal fired electric plants but I agree all electric
cars do is move the smoke stack down the road a ways.

In my opinion that's an over simplification. For one it ignores the
fact that stationary, large-scale power plants are much more efficient
than the average internal combusion engine used in vehicles. Secondly,
the charging is usually done at off peak hours when there is typically
excess grid capacity. Last but not least, the trend is pointing in
the direction of renewable energy such as wind and solar. If we live
long enough (doubtful), we might even see clean nuclear fusion some
day. As an additional benefit, electric cars have done quite a bit to
advance the state-of-the-art for light weight, high efficiency
batteries. Those gains will eventually prove useful for the storage
of wind and solar energy.
That all assumes a clean power plant in the first place. The article
was talking about coal plants and we still have plenty of them.
Your solar power is not going to do much if the cars are charged at
night.

At least in this country, coal plants are rapidly going away.

Solar power at night is not going to happen of course. New battery
technology, and other energy storage devices, will eventually help
with that issue however. If every south facing roof in Florida was
covered with high efficiency solar panels, there would be plenty of
energy to spare for battery charging. I think that will eventually
happen as the price of solar panels steadily decreases.

My problem is drilling holes in a roof that isn't leaking now. My
roofer neighbor says solar is great for his business. I also only have
about 3kw worth of south facing roof.
Solar is getting a lot cheaper tho. I was looking the other day and
there are lots of collectors in the 75 cents a watt neighborhood.
I wonder how FPL would feel if I built an array on their property ;-)
Running those cables to/from that array near their power lines may be the biggest problem.You may create a transformer that neither of you want.
That is way overstated. I have tried to scavenge power from those
lines for 35 years with absolutely zero success. If you believe what
you see on you tube I should be able to hold an F40 tube in the air
and have it light up ... nope. I should be able to string a wire
parallel to the line and generate something ... nope.
Coil of wire ... nope.
I really wanted a light in my boat house under those lines without
stringing another wire but no joy.
If you really look at these lines it is easy to see why. They are a
twisted triplex. They just have a twist about every half mile or so
but that is still way smaller than the wave length. (roughly from here
to California)

Besides, my wires would be running at 90 degrees to the power line and
underground.

There are a lot of LED lights that are charged with small solar panels.
Pretty cheap, too. How much light do you need?

===

Yes, there are lot's of solar powered garden lights that should do the
job, probably at less cost than trying to build a giant transformer.

Nikola Tesla would disagree. :-)
