Does that include lorries?
BTW, she has obviously not sat down and calculated how many new power stations will have to be built to handle a [spiky] demand.
The arithmetic is simple.
The "average" household uses about 20kwh per day.
Driving the "average" car for an hour will use about 100 kwh.
Recharge is typically early evening.

Not only that, but if an average electric car costs $8000 more than a similar gasoline car, that $8000 will need to be produced by every purchaser. That means all the diesel, coal, etc. that is consumed in producing that extra $8000.

In any case, if, as many members of this forum suspect, we are entering a cooling phase with potential energy inefficiencies, these plans will become moot.
If the grid struggles or even fails to supply heating in the winter, it sure as he'll wont supply the balance of energy currently fulfilled by hydrocarbons, ie, the national car fleet.
Then again, as lithium batteries are very inefficient at storing power at low temps, i guess alot of cars that would even be rendered house bound in any snow deeper then 4 inches wouldn't be used anyway....
Lithium batteries are very bad in the cold. I'm not sure how car manufacturers engineer for this, however I know that photographers working in cold environments keep their batteries in pockets close to their bodies to maintain charge. Hell my own power tool batteries noticeable drop in power and duration on a cold morning. I charge and keep in overnight when cold, I've had good batteries perish because I left them in the van overnight....
So what's the deal with charging an electric car outside your house in -5°c?? Sounds to me it would require addition heat to charge efficiently and be if use in the morning??

blog.ucsusa.org/dave-reichmuth/electric-cars-cold-weather-temperaturesSo yes, uses more power to charge when cold as battery temps maintained, then due to warming of cabin for comfort and keeping battery warm range is reduced. So there's no point in buying an electric car if your daily range is maxed in normal conditions....youll struggle when its cold...

Despite the solution to our problem staring them squarely in their collective faces, Australian political morons are now considering subsidising large businesses to use their stand-by generators.

Well as the title of the thread says - they are only copying UK Government who are doing the same thing.

[Snip ] Well as the title of the thread says - they are only copying UK Government who are doing the same thing. Was that supposed to make me feel better? Got some really polluting diesel generator sets? You too can bid to supply power to the UK National Grid as they have shut down clean coal power stations for virtue signalling and have now realized that a cold winter and there will not be enough power even by shutting down industries to a '3 day week' (tm Prime Minister Heath) Even the tabloids have started to notice. www.express.co.uk/news/uk/444213/The-Last-Big-Blackout-40-years-ago-the-lights-really-did-go-offSo now we have Short Term Operating Reserve (STOR) ** fields of diesel generators that can be fired up to supply smoke and micro particulates and get the politicians out of a hole. They have a call for tender out still.... www2.nationalgrid.com/uk/services/balancing-services/reserve-services/short-term-operating-reserve/** Some tax payer funded civil servant sat for hours playing with words to come up with that acronym then they would have had a focus group and several high level meetings to agree an acronym for their failure.

Maybe, maybe ..... there is a little light at the end of the tunnel. Maybe it's not a freight train:

When the various governments create a 'can't lose' investment by providing bottomless subsidy _and_ guaranteed feed in tariffs regardless of whether the grid needs the power - then of course you get investment. As soon as the governments take their thumbs off the scale the investments will stop, literally within minutes.
So now we can see South Australia and to a lesser extent UK, with their power supplies literally dependent on the vagaries of the wind and clouds. All because of inept virtue signalling politicians. People are going to die in their thousands because of these politicians.

These large subsidized wind farms which stretch for 40 or 50 miles are certainly a type of pollution. I drive west for the scenery, and they are part of the scenery.
