Actually electric cars would probably be good for power utilities, esp
if they are being charged at night -- kinda like the rural night lights
that allow baseload plants to operate at a higher capacity. (we have
one, I don't think we get charged for it, or maybe something like
$5/month) The utility can keep baseload power plants running at higher
output (or have more baseload capacity installed and operating) at
night, dumping power into car batteries, that will help lower costs.
Baseload plants are generally coal or nuke. Less peaking power (more
expensive oil or gas-fired) will be needed during the day time when
loads are higher, as there will be higher loads at night which can be
met with baseload plants.
There is also some scheme that the car batteries could be used for
load-leveling or on-line reserve to level out wind or solar or other
variable loads/supplies. That would probably require some sort of
management scheme, something like what electric hot water heaters have
(if your utility does that).

I never cease to be amazed that the journalist types who hype this stuff in the
daily newspapers never seem to
notice that there is not likely going to be any heat available in this nice
little electric car. I live up here
where the ground is white for a lot of the year. I want to know how long the
battery will last when it is minus 25
out and if I get electric heat as part of the deal.
I also want to know if the battery can sustain AC for my short trips around
town in the summer.
No one seems to make any comments on these issues. It is all about the
environment and the utopian dream that we
can carry on without polluting anything. Nothing practical ever mentioned.
Also have to wonder what happens when a couple of hundred thousand people plug
their car in at night. Does the
power go off all over or just in some areas? Do you have to shut off your house
AC so you can charge up the family
buggy?

230 MPG sounds like magician's BS to me.
It goes like this: you drive 40 miles on the battery, totally depleting it, and
reducing its lifespan. Then you start the engine and drive ten miles. Since you
used a quart of gas on your 50 mile drive, you must be getting 200mpg. If
politicians can lie, why not corporate PR hacks, especially from a corporation
run by politicians?
