Energy grid wouldn’t survive quick mass EV adoption most likely. Heck, how would you even charge a car if you don’t own a house - ideally parking places would have a slow charger where you could recharge car during night for cheap.
It can be, and traditionally has been. But how fast do you think you can bring a solar farm online? Securing the land and zoning is probably the biggest delay, followed by running lines to the grid.
Huge is subjective, but there are many solar farms today running on just a few acres. Some quick googling says that community-based and commercial farms typically run on 10-40 acres, generating between 50-200 megawatts. If you consider 40 acres to be a huge farm, then sure. But it doesn’t make much sense to run these in a decent populated area anyway. This is no different than coal, gas, or other power plants today, albeit for different reasons.
As for huge batteries, yes, we will need them once solar power capacity reaches a point where generation in the day exceeds the demand. As it stands, many places still have off-peak pricing at night. Solar would need to counterbalance that completely before we need huge batteries for solar.
Gas tank fills in 5 minutes if you are empty and have a large tank to fill, otherwise less. Also, if I know that I am going to be away from gas stations for awhile (camping, offroading) I can fill up my can and carry that with me.
That’s tricky though. Would you deplete it during night to have it empty in the morning? Wear expensive battery? Plus, I assume, car is disconnected from grid for most of the day (i.e. when you are at work).
“solar-powered cars” have been tried many times because it’s a great headline, but the math never works. Cars simply don’t have enough surface area to capture a lot of solar power. The amount of energy is low enough to not be worthwhile, except in the most extreme edge cases.
Yeah a day you can get 2% of battery, but this would make extend range and make it more susteninable considering rooftop and hood space is always unused
2% is probably near the theoretical maximum, too. Actual output considering weather, efficiency losses, etc is probably less than half that. Solidly in “not-worth-it” territory for most use-cases. Heck, my car won’t even properly charge on a 120V outlet when it’s too cold, because it needs to heat up the battery to a safe temperature first and at -20°C that takes more than the ~1kW available from the outlet.

Idk they’re making it work for data centers and those need way more energy
The quick mass adoption is happening in Scandinavia now, and we’re ok
We’re blessed that it can survive the datacenters though
EV adoption can’t happen in a second. If more EVs are sold, countries can just expand grids and charging networks with it.
Expanding energy grid is a slow process. Like really slow.
Just like replacing all cars.
Is it? Seems data centers are able to do it quite quickly, and all at the cost of local taxpayers.

You would need huge farms and huge batteries. The first can’t be built in the city or in any densely populate area and the later is a big challenge.

Seem like the greatest solution, these EV can also act as battery storage for renewables.
That’s tricky though. Would you deplete it during night to have it empty in the morning? Wear expensive battery? Plus, I assume, car is disconnected from grid for most of the day (i.e. when you are at work).
But you park it at work there could be slow AC charger, to slowly charge it when you are away.
Placing solar on rooftop of car also seem as good idea

You don’t have to charge 100% using solar

No, I don’t think so
