Since electric motors should be much more efficient than internal
combustion engines the above figures are pessimistic but even if
the power requirement was only 30% of the above they'd still be
problematic.

If we can actually produce an acceptable battery car in due course
for more than intra urban short hops, then all the infrastructure
is buildable over the same sort of period that a petrol and diesel
based infrastructure was rolled out in the last century.

Yes. What worries me is that we may find that we have to alter our
habits, scheduling in longer breaks whenever the car is getting low
on power, whereas we are used to filling up in a few minutes
whenever we need to (without having to plan ahead).

It's fine for people who have a commute with recharging points at
both ends,

How many people drive 120 miles to work and 120 mile back every day?


I did 843 miles this week and it's a 4 day week.


But most people don't commute to sites hundreds of miles away. So for
them there wouldn't be any need to charge an electric car at work,
just at home. It makes a big difference to how much infrastructure is
needed when they can recharge the 20 miles they have driven overnight
rather than a full charge both ends.

Except of course that these days most people change jobs a number of
times, so they can have a nice short round trip to work one month and
the next could be much, much further.

I would have an electric car if they weren't so expensive. I rarely
drive more than a hundred miles these days. Too knackered from the
chemo to do much more.

An electric car would make sense for my wife (and for me to borrow at
times), but even the "rarer" longer drive would mean that my car needs
to be petrol or diesel.

Electric cars are unlikely ever to have sufficiently quick charging and
when they make affordable Hydrogen powered cars, that is when petrol and
diesel will have a viable replacement - assuming enough power can be
generated to release the Hydrogen in the first place.

they could do that when it's windy
