Enough with The "Electric Cars Pollute More" Bullshit Already

The author of this article doesn't know what they're talking about. The amount of energy we can store just isn't enough to supply the grid when wind and solar stop, and probably won't be for quite a long time if ever. (The "ingenious ways" they're referring to is pumped hydroelectric, which suffers from a severe lack of suitable sites, most of which are already in use. It's also probably one of the first things people think of as a solution.)

But it is easy to imagine something much more advanced. Given some input like how long we've been plugged in, if we use the app to say "charge now", what utility we have (by selection or by GPS possibly), interact with the utility to adjust the charging rate.
At the moment I'm just set to charge starting at midnight. This is for 2 reasons: We recently switched to a 3x higher utility cost from 7pm-10pm, and also the car charging when I plugged it in made it hard to read my bill. We have these bills that say "You use X% more energy than your neighbors, can you think of anything you do from 5pm-7pm that you could cut back on?"
Its also important to point out that a large fraction of renewables used by Germany are biofuels that are significantly more reliable than wind and solar but are not what people here think of when they talk about renewable energy.
In reality, Germany is so “successful” investing in renewable energy because it is a rich country willing to spend significant amounts surrounded by neighboring states willing to provide electricity. In reality, renewable energy is still significantly more expensive at he moment and adding storage into the mix just increases the cost.
Well, that's probably a gasoline powered SUV or truck in the US.
In Germany, you typically have smaller cars, much smaller engines and, well, Diesels, which these days easily manage around 5l / 100km, and that's in the range of 120 g of CO2/100km. So definitely competitive with the Tesla and with those small differences, differences in production become more relevant.
The studies I saw indicated that when driven long distances, Diesels are (still?) somewhat more efficient than EVs. Over short distances, EVs are better, but then you typically aren't driving a lot, so the extra production costs may not be amortised over the life of the vehicle.
The best case for EVs are vehicles that are constantly moving, but only small distances with lots of stop-and-go. So public transit, taxis, etc.
That said, I'd still prefer an EV if possible: quieter, fewer/no emissions at point of use (so less concentration of emissions in the cities), amazing torque, fewer parts, etc. And once we go fully nuclear/fusion it becomes a real no-brainer.
And electric propulsion for airplanes is also really interesting: short power bursts possible without much weight penalty for cruise, cost, reliability, noise (big issue in Germany, the only country in the world where people can see airplane "noise")
Can you clarify?
It's really quite silly.
But it's not happening tomorrow, it's happening in the next decade and any respectable grid operator is already planning the changes such that it isn't a problem.
Depends - shock load with fast charging, at least according to the Ars article, can cause the coal plants to fire up.
