						EVs won't overload the electricity grid. We actually have enough power, but the interconnectors need upgrading to move it around. For example, Snowy Hydro won't work unless $2b is also spent on grid upgrades to move the power. Renewables are also decentralising the generation of power. EVs will charge overnight from batteries which were charged by solar during the day. It's already happening.

						Enough for what? For powering today's EV fleet, absolutely. For replacing every ICE vehicle in the country with an EV and maintaining current usage patterns, I seriously don't think so. Last count, there were 19.2 million vehicles registered in Australia.
And the electrical generation mix we have today is among the most polluting in the world, esp in terms of CO2 emissions. So switching to EVs and having a clean supply means both replacing much of that existing generation as well as building a bunch more.
My point exactly. In order to support a mass adoption of EVs with clean electricity we would need many millions of distributed PV + battery systems (the model you've suggested), but that's not the only option. There could be large-scale wind/solar/hydro plants, grid-scale storage, and nuclear in the mix. Big $$$$ for new supply no matter which way you carve it.EVs will charge overnight from batteries which were charged by solar during the day.
Aside to the bloke who mentioned the CSIRO ammonia/hydrogen membrane... could be useful in some stages of the hydrogen supply chain, but has its own energy bill associated with it too. Worth keeping an eye on.
I like LR's MLA approach with a mix of different chemical/electrical motor options. It's smart for them because there will be a wide range of customer scenarios. "Working" Defenders I bet will be largely the mild hybrid variant for a good while, while city folks might go the full BEV. The PHEV offered in the RRS today is awesome as a drivetrain but it takes up so much space that you can't carry a spare tire. At least the Defer won't suffer that particular compromise.

						I've been looking at that Rivian, but realised that with the full size 180KWh battery to get the longest range, to have that on-tap in a house battery, it will take an equivalent to 13 or so Tesla Powerwall-2 batteries for a full charge, which at $12k a pop = $156K !
You may not want a full charge every time, but that would be worst case.
Also, if you were using an average 5KW solar array, it would take 36 hours of charging, which assuming you could get 9 hours of charging a day, would be 4 days to charge it. All this while the array is not used for any other household power.
However, you could potentially charge it using off-peak power, if that is permitted, at a rate of roughly 10c per KWh (is that about the off-peak rate?) . Standard GPO in your house is good for about 2.5KW (10A) , so you would need the equivalent of 180/2.5 = 72 x 10A circuits over however long the off-peak runs for.... Not sure how long off-peak runs for overnight, but assuming you get a 8 hour window of off peak power, then you would need a 90A circuit to completely charge up the 180KWh battery overnight on off-peak. But it would cost less than $20 to charge.
Could somebody please check my man-maths ?

						Which is why a 110 is such a perfect all rounder, daily driver, work vehicle, tourer.and why a contemporary HD 130 would be perfect to compete with 70 series and the dualcab clones. Not RETRO - cutting edge, and more heavy duty than all the current clones. ...it would make no sense for JLR to ignore the work vehicle market with new Defender.

						And we all know why that’s the case....so what a perfect opportunity to rectify the errors of the past with the launch of an all new model.
NB: the discerning amongst us who saw through the Tojo spin bought Defenders as work vehicles. Despite all the claims to the contrary, I still believe Defenders to be more capable, comfortable, robust and heavy duty as work vehicles than 70 series. They are also equally reliable if serviced properly, cost significantly less to purchase and are cheaper to run by far. There is no reason whatsoever that JLR can't produce a new HD work vehicle - will they? The jury is still out...
130s are popular here and in some countries for heavy trades work.
Charging an EV at home similar to people who charge caravans and campers at home - we do it. Very common thing. Really, this is not a hard thing - it's very simple.
And most charging would be at off peak times so the electricity network would have plenty of spare capacity.
