Both are the same thing essentially - improvements to the efficiency at the cost of upfront capital above and beyond "the norm" for such tasks. There are other variables in play too - stoves that boost fire efficiency are tech available centuries ago while electric cars are still progressing and have R&D baked in. Stoving everyone up would hit its limits for enviromental improvements before electrification of cars. It is a matter of proportion of use as a whole that they become comparable. A single wooden shack with a camp fire produces less air pollution than a coal power plant and a single concrete tenament but ironically if you have enough campfires concrete tenaments with coal fired electric burners and heat it becomes the cleaner and more efficient option compared to many wooden shacks and firea even before you start adding scrubbers.
