The answer is simple. When everyone gets home from work and plugs
them in, the lights will go out. Throughout the country. And our UK
electricity grid is more robust than in the USA. (At the moment.)
When you put petrol in your car the pump is delivering about a Mw of
I suppose the effect could be moderated if there were charging points
at work but then who's going to pay for that?
Super/ultra capacitors would make things even worse.
Also the gov in the UK is making a fortune out of fuel taxation, how
are they gonna tax your fuel for your electric car?
I'd buy an electric car if it had a range of say 100 miles when the
battery was new. I could manage as it deteriorated to say 30 miles.
( but only for 95% of the time.)
And if it was the same price or thereabouts as conventional car.
And if I could get a big solar panel too charge it for a reasonable
Nope, it ain't gonna happen. What will happen is that we'll all be
back (in my case) on the buses and trains.

Government has been concerned about this not only with electric cars but
also high mileage cars. Solution will be to tax based on miles driven.
Cap and trade bill in US will also take care of the government if
implemented it will bring in huge tax revenues.

Can yo imagine the mess this will cause as everyone tries to move
closer to work.

One of the models for urban electric vehicles has interchangable
batteries provided by a service company - who owns them and charges
them up at night and off-peak. The consumer buys the vehicle -
contracts the batteries & battery power. The battery-change-out
stations would be bigger & more elaborate than our gas stations - but
not restrictive. Perhaps a fleet of "tow-trucks"
.. lets call them "go-trucks" with battery-change-out capability.
Lots can be done in that 50 mile radius around our urban centers.
The urbanite's "second car" - the gas guzzler - would still make
the trips to the cottage and Disneyland - but would last 20 years or
more - because of the reduced urban use.
ps : think nuclear power plants - not coal/oil/gas

I guess nobody told Nissan yet huh? They just announced a mass-market
No, you got that 100% wrong. Grid capacity is one reason why electric cars
are unlikely to become ubiquitous any time soon. Our present grids can
easily support millions of electric vehicles, particularly in off-peak
What? You want cars to charge during peak load hours? Really?
How so? Just because supercaps CAN be charged quickly does not mean that we
MUST charge them quickly.
Don't worry, the bureaucracy will figure that one out!
I might be a customer also, but it would depend a lot on the price and
operating expense of the vehicle compared to its capabilities/limitations.
Strangely, now that I am retired and my transportation needs have become
simpler, I find that an electric car may not be a good match. First, I no
longer have need for a second car so I would be stuck 100% with the electric
car's limitations. Second, since I now drive fewer miles, I now have less
economic incentive to invest money to lower my transportation costs.
You are confusing transportation expenses with energy expenses. If it were
cheaper to charge our electric cars from solar panels, then it would also be
cheaper to run our homes from solar panels. So if solar panels were
suddenly much less expensive than today, we would all buy them and connect
them to the grid with net metering.
Further, it will be most convenient to charge most electric vehicles at
night; exactly the time when solar panels are quite usless!
I agree that it is unlikely to happen anytime soon, but we seem to differ
greatly on the reasons.
