Stop it Willo. People are gunna start yelling at you real loud n calling you names if you keep this stuff up.

They already do.
I wonder how big the batteries are gonna be on all the trains. What sort of batteries and solar cells on ships? Or do we go back to sail powered clipper ships.?
How about international air travel? Imagine getting a flat battery midway over the Pacific.
There would be quite a few passengers flapping their wings then
Then there’s the idea the ev’s (batteries) would power homes at night when solar cells don’t work.
Apart from the fact that you need to charge the ev after using it during the day. What are you going to plug it into to charge the vehicle up?
Or if you need to use the ev at night.
What do you use then?

and it's going to happen.
Lots of cars sit at home all day and will charge or you will charge them at work where they just sit there all day too.
If you want to use it at night you do - most vehicles will be in the shed so it works (unless Tay Tay is in town I guess)
About the system balance vs individual effects.
The big challenge is that you need to convince society (or make a law) or incentivize the market to allow a corporation or government to control when you charge/discharge. That will probably be the bigger challenge in a democracy.
No doubt some cars will sit at home and will charge. If they charge at work and you still have to drive them home again.
But what about the ones that don’t is the question I asked. What base load power will charge the ev’s at home at night. Or at work, what size solar farm are you going to need to charge all those cars in car parks or what size solar will employers need to install .
Or at Woolies. 500 hundred cars in the car park while shopping, getting their hair done .
Do you know what size solar system, battery, monitoring etc will be required for one small ev to charge from 1/3 charge to fully charged? Does anyone know?
What about large ev’s that replace semi-trailers and road trains? What capacity will be needed to charge them?
What about freight trains? Airliners? Shipping? Farm machinery?
It’s another pipedream that corrupt politicians are inflicting on the population. If you want to drive an ev, do so. just leave the rest of us alone
Good questions but not very solution oriented. It’s a fifteen/twenty year transition issue and you are fixated on the now in your reasoning.
The other one you should ask is what percentage of battery use do people use on average each day and how many km spare do they need for an emergency. It’s a social problem - you charge to 100% during the day - get drained a little overnight, drive somewhere in the morning and then recharge when there is excess capacity. If you have a big trip planned you don’t allow your car to get drained overnight. This is the big social problem the load switching required.
At the end of the day when rooftop solar plus battery is cheaper than whatever alternate the switch will happen even quicker.
If we get away from the absurdity of green hydrogen then electrifying things will actually generally reduce energy consumption because it’s just more efficient and the more behind the meter stuff we have then the less transmissions wire and poles are needed too.
These are all engineering problems that are eminently solvable with existing and foreseeable future technologies and the right transitional processes.
The thing is,they aren't here NOW,so Bowen and all the other renewable fanatics need to have patience.
A good question by Willo though,Trucks will need huge battery capacity ,otherwise there will be mass delays on all freight,planes are not going to be run on renewables ,same as shipping .
No they’re not. That’s the biggest fallacy ever.
Needs vs supply. Age old problem. They can’t generate enough electricity or deliver it where it’s needed in a lot of cases. It’s hwy they have brownouts and blackouts.
The baseload demand required once coal and gas fired generators are taken off line and I take it it zero nuclear generators is beyond engineering problems. There is zero combination of technologies that can generate and store what’s needed. Zero..
”Future technologies” what a trite couple of words. Which actually means there is nothing available that can generate and store what’s required. Ever.
But we hope someone with a magic wand will make something happen. Somewhere. Sometime.
What it is, no one knows. But we need to head there a fast as possible.
But in the meantime we will still enjoy all the comforts, facilities, technology, travel etc that uses coal and gas fired electrical generators that we take for granted.
We know it’s bad, but we can stick a couple of solar panels on the roof, ride a pushbike to work twice a week and drive a hybrid car.
”We’re doing our bit”.
Daydreamers and Hypocrites
I’d like to see how they’ll run a RC air conditioner off a battery when the temperature hits 35 - 40degrees C at night 
or during the middle of winter. No wood fires allowed just plenty of thermals for the whole family.
I wonder what we’re gonna cook our dinner with? Can’t have gas cookers, no wood stoves. the old battery won’t last long pulling 15 amps out of it.

Dunno what you think posting endless clickbait videos is going to achieve. Unless you're just trying to drown out discussion.
So, we just screw up the climate do we?
There is no alternative, we have to stop using fossil fuels. We are already seeing the impact of climate change.
Nuclear? What a stupid suggestion. Apart from the fact that the so-called small reactors do not exist, conventional nuclear reactors will give us power for, maybe, decades. According to the nuclear lobby there is about 100 years of fuel for nuclear reactors at current usage levels. Double the usage and we get 50 years of energy. All this and it comes with 250,000 years of toxic radioactive waste which, after 70 years of the nuclear industry, there is still no safe way to dispose of the waste. Stupid suggestion and won't happen in Australia anyway.
The solutions are things like wind, which blows at night, solar collecting, which work overnight and other power sources such as hydro, including pumped hydro and tidal power. We need, and we can, improve technologies.
Storing electricity is extraordinarily difficult, we do need to find better ways, and we need to be sorting this now.
Plus, we need to be far more efficient with power use.
This is not a choice, we cannot continue to stuff up the climate.
Such a pity that the right wingers and fossil fuel lobby have been holding back action on this for decades, now we have so much less time to make changes. We have wasted way too much time, we need to get going now.

And yet to want nuclear tech which would cost 5 times as much and take 20 years to build.
And while the cost of renewables continues to fall at much faster rates than even the renewables industry predicted in it's best case scenarios.
You understand economics about as well as you understand tech.
Just showing an opposing view for the indoctrinated daydreamers who don’t have much of an idea
