Josephus, I think the nonsense in Glasgow is because they have brought
in a flock of electric range rovers etc so there is not enough public
chargers installed because they are not needed normally.
Most EV owners charge at home and have freed themselves of the pain of
having to get to a service station at inconvenient times.
The other reason for the generators might be to keep the lights on in
the meeting halls etc.
How embarrassing would it be if the wind failed again during the
conference ! You would hear the laughter in Glasgow all the way from Sydney !

LOOK ! to make it clear, electric cars are not about global warming
or being green or any of that nonsense.
It is a better technology and petroleum has run into the cost problem
of producing it in the quantities needed.
It started back in December 2005 when peak crude oil occurred.
It has been hand to mouth ever since by topping up with fracked oil
and cars with lower consumption.
It cannot go on forever and the oil companies know it. That is why
they are investing in other forms of energy.
Royal Dutch Shell CEO made it clear to his shareholders.

The problem with that Bazz is that while it stays a boutique industry it may work, but the only way we can possibly generate enough power to charge even 10% of cars if they go battery electric is to use Coal, gas or Nuclear.

You are going to have a pretty big chore getting either up & running against the ratbag green oposition.

Don't think so Hasbeen.
Visualise it; Kids rush in from school, hungry, hot and want the telly on.
Mum, or perhaps Dad is starting the evening meal prep.
Something on the stove bubbling away. The power goes off as Dad plugs
his car in. The last one home in the street.
Because it has been an overcast day, and no wind for a few days,
the fancy battery backup wasn,t in the race, the kids go beserk and
Mum screams at the kids and Dad and wants nuclear power by tomorrow
so to speak.
In a nutshell that is what will happen.
I believe there are 20 million cars in Australia, about 1/3rd will be
plugged in each night.
Guessing a bit, about 5Kwhrs over 10 hours for say 6.6 Mill cars
is something like 30Megawatt demand over whole country.
However there are a lot of cars like mine that do not move for a
couple of days at a time and can be charged during the day anyway.
Norway must have some figures on that.

It is not just cars that use rechargable batteries, all independant vehicles use batteries, fork lifts, Mopeds, lawn mowers, power tools the list is endless.

Woops, think I dropped some bits there, I think it is 30Gwatt.
Seems more reasonable. Still spread over the states a few power stations
could eat that for breakfast.
