CO2 isn’t particulate matter. But more importantly, larger percentages of our electricity is being made without burning things.

Power plants are usually not placed inside cities. Less gasoline cars inside cities will definitely improve the local situation, not just limited to CO2.

What does CO2 emissions of electric power plants have with air quality in cities ?

Nuclear power is a good option, wind and solar are usable for charging batteries - either EV batteries or storage banks which can be used to charge EV batteries. The problem with wind and solar is that there is no long-term storage solution as of yet but single-day storage is already achievable. Once enough nuclear capacity has been built up I foresee wind turbines disappearing from the landscape since they are cumbersome bird-killing eyesores. Solar power is there to stay since buildings need roofing anyway and we'll soon be at a point where the price difference between 'passive' roof cladding and PV 'panels' is close to negligible so it makes sense to install PV roof cladding and get some power for free, especially in places where air conditioning is popular.
