No they don't.
The UK national grid estimates there needs to be a 4-5% increase each year, for roughly 15 years. That's achievable.
The US won't be too different.
Why quadruple. Where are you getting this from?
They obviously won't.
Fossil fuel power plants don't count. EVs running of fossil fuel make no sense. Remove them from the equation and my prediction becomes extremely optimistic.
In what world don't they count?
They can power EVs. And running an EV on fossil fuel electricity is still far less polluting than running a petrol or diesel car.
One large generator at its most efficient setting is far more efficient than tens of thousands of small ones starting from cold multiple times per day, that aren't necessarily maintained well, and are constantly going through their rev range.
Where are your sources for any of what you're saying?
No , if you run EVs off a grid fossil fuel generator, that's the difference between 33% and 40% efficient. It's not enough to move the needle. It doesn't even pay for itself in terms of emissions.
The energy source absolutely has to be ZERO emissions as well. If not then it's just climate cope.
EVs are currently running partially on fossil fuel just fine and generating less pollution than ICEs because power plant efficiency is still better than combustion engine efficiency.
That is nowhere near enough. It's 33% versus 40% difference between co2/kWh . we need zero co2/kWh or else it's all a waste of time.
It's only acceptable if we are transitioning to zero emission grid. If we stay on natural gas then it won't even move the needle.
We are transitioning towards it, but in the meantime, switching to EVs still reduces CO2 output and because the grid is getting cleaner, that means EVs get cleaner even after being manufactured and sold, whereas ICEs can only get cleaner through R&D and only get worse over time as they age (once they start burning oil, etc)
