The Grid operator in a report has warned that they are having
significant trouble keeping the network stable and reliable with the
increasing variable generators and they expect it to get worse when
other coal fired stations close. This situation started with the
closure of that Hazelwood station.
There is talk of demand control and I imagine electric car charging
would be a prime target. So you could get up one morning and find your
car only half charged.

What seems to be the way drivers use their cars is that if they have
gone somewhere distant and the return trip is greater than their range
they stop at an on the road charger and charge for the time to get
enough range to get home.
The dashboard displays that. Then they charge overnight.
Isn't that what you do with a petrol car ?
How many times do you undertake a return trip further than 430 km ?
Also in Europe many employers are installing chargers.
It looks like around 400km will be the range that most manufacturers
will settle on as a compromise.

Forgot to mention a Dutchman is about to arrive here in his Nissan Leaf
having driven from Holland to Asia.

Also a number of people have driven around Australia in Electric cars
with some difficulty of course but it will get easier.

We will not run out of electricity, we may pay more for or
Equally in time, it may get cheaper
Solar needs no wind, hydro needs no wind
The next generation batteries may hold much more power than we even think now
Nuclear, if we can sideline the fearmongers, could supply all our power on its own
Take the politics out of our power system and let science lead

Bazz,
>We are going to be short of electricity, definitely if Labour wins.
That's an absolutely ludicrous claim, considering Labor's planning to implement the NEG unlike the Libs who were too scared of Abbott's faction to implement their own policy.

>We will be short of electricity at night as any sailor can tell you the wind drops off at night
If you have a look at http://opennem.org.au (and uncheck all the boxes except wind) you'll see that wind doesn't usually drop off at night. If the past week's anything to go by, it's generally windier at night than in the daytime!

The wind drops off in high pressure conditions, but those tend to be sunny.

>There is talk of demand control and I imagine electric car charging would be a prime target.
>So you could get up one morning and find your car only half charged.
Demand control is NOT supply curtailment. With demand control, if you set your car to fully charge then it will fully charge. But if you set it to minimum half charge then when the wholesale price of electricity is high it will half charge, and when the wholesale price of electricity is low, it will fully charge.

Cheap rate electricity at fixed times of night is becoming a thing of the past. A flat rate seems to be prevalent at present, but charges based on the wholesale price are almost certainly the way of the future.

We have an election coming, we are watching the coalition get near to war, again, on the coal mine in QLD
Anything can be said about power right now, and is/has and will be
Indeed that issue, climate change energy policy has bought more lies to the surface than any other
It was the reason Turnbull fell
It may, yes true, kill any chance Scomo has, if it explodes again
But beneath it all the world is progressing
EVs will not come by a huge millions of cars overnight
It will come one step at a time, but come it will

Internal combustion engines will be around for a while yet and steam looks good as always.

Anyone undertaking a long trip away from the grid can tow a light trailer with a generator powered by an IC or a steam engine to keep the power up, probably even be able to do it on the move, sort of a hybrid.
