They are assuming coal fired electric plants but I agree all electric
cars do is move the smoke stack down the road a ways.
You could say solar fixes that but most of these cars will be on the
road when the sun is shining and get charged late at night when rates
are lowest.
I suppose you could put solar collectors on the roof of daytime
parking garages and charge a few cars.
Like most of these schemes, as long as there are not many of them,
they look good. A garage even less than half full of electric cars
would eat that solar energy far faster than it gets collected.
It is like those guys with a solar collector on the roof of their golf
cart. It is great if you only use it every other day, don't use it a
lot and keep it parked in the sun. My charger puts out 20a at around
40v (0.8KWH) and it takes ~8-9 hours to recharge the batteries.
The usable capacity of a typical 36v cart is 8KWH or more depending on
which battery you choose.
I bet Bill's Volt is close to 10x that. Certainly a Tesla would be
much more.
