Just curious, how do you know that your car produces less pollution? The electricity is still generated and transmitted, so it is at least possible that the energy used to power your vehicle is worse for the environment because of its source. Also, did you factor in the impact that mining lithium has on the environment?
Even in the absolute worst case, energy generation from fossil fuels at a power plant is significantly more efficient than the internal combustion engine, even after taking transmission and charging losses into account.
In reality, EVs tend to be sold in areas with high renewable penetration. And about 40% of EV owners have rooftop solar systems.
The biggest argument for EVs in general is that they are fuel agnostic. Transitioning to EVs right now means decoupling transportation from fuel, which means the fleet automatically becomes cleaner as we continue to build renewable capacity and phase out fossil fuels.
If you look at serious research on this (full life-cycle analysis) you find that a small electric car typically breaks even after ~ 60 000 miles, while something like a Tesla Model S breaks even after ~ 120 000 miles. Those numbers are from memory and for a European electricity mix, but I'm fairly certain they're in the ballpark.
As well as the other answers, when I charge at home the electricity comes from my solar panels.
Now, we can argue about the polluting nature of creating the panels - but I can turn a day's worth of sunshine into 80 miles of travel with no at-source pollution.
