Various studies show that even with our current power grids which heavily rely on fossil fuels, electric cars overall pollute less than a typical gasoline vehicle, mainly because the thermal efficiency of power plants is much higher than of the average combustion engine. Grid and charging losses included (Some exceptions apply with carbon power plants where when combined with grid losses would make it worse).
However this doesn’t mean that electric is a great solution yet. As you say, to charge all those cars, probably overnight, you can’t even use solar power.
Unless we finally realize nuclear power has been proven safe, clean and reliable, we will never have a clean power grid. 4th gen reactors have the potential to reduce nuclear waste 100fold, they just need more funding.
The Hyundai Ioniq has been my favorite electric car in the market for the simple reason that it has the highest efficiency of any EV on the market (and by a lot). They managed to get a decent range with just a 28kWh battery. Meaning that this car uses less resources for production and has the lowest overall emissions during operation. Still the range is a bit low, next year’s model is expected to have a 38kWh battery, which shouldn’t add much significant weight.
