Somebody worked out that if Victoria, Australia, went fully EV we'd need an additional 10 GW 24h a day to charge them. That's several large power stations, or if you prefer, 60 kW of solar panels per household, ie 12 times the typical installation. +storage+it won't work in winter.
So 21,000 acres of PV (120W/M2) in a state of 56 million acres...in the wettest mainland state of Oz. Hardly the end of the world. And it's not like Oz doesn't have millions of acres of sun-soaked wasteland lying around, does it?
Entirely doable if one wanted to. And that's the biggy - if.
How's the PM and his close relationship with coal doing these days?
Upfront, I am no Aussie, I live in Austria.
However as a principle, the challenge lies not in converting the energy to power to your socket, but in storing it.
Even in Australia there will be a time of the day when solar will not be able to provide much to the total demand of electric vehicles (due to the Sun going down and dimishing efficiency of the solar panels, and other factors), hence you need to release it from 'a storage'.
As there is no silver bullet, you would need vast storage capacity even for a rather small city, if each of them rely totally on power.
So, if you cannot do it centrally provided by your power company, the politician's general approach is to have the invidual pay for it.
Thus some incentives given, at least in Europe.
I have a modest house and am currently considering putting a 5kWp system in my roof, as I simply do not have more space.
But the majority of the costs, even if I only want to store a fraction of the solar energy, are the batteries.
This is the Achilles Heel. At least to me.
