As stated earlier, the numbers depend on how clean the grid is where you live.
Retry the experiment for someone who lives in Delaware...
I also ran the numbers for Neil B in MA, he'd be 25% 'cleaner' with a Prius.
If you leave the state blank you get the grid national average, the Prius still wins on that basis.
There's no point buying an EV today in the hope that the grid will get cleaner, the clean grid has to come first or you're just making another mistake. Replacing oil with coal is like replacing cyanide with arsenic.
So by challenging the easily disproved idea that EV are always 123444$355% better than ICE I am helping. You're welcome
