If you want to know there’s plenty of reliable sources like the doe (and if you want confirmation bias rather than facts, there’s plenty of unreliable sources)
Last time someone made a comment like yours, I actually tried googling and there’s a doe site that actually tells you the carbon emissions by state for an ev, hybrid or normal gas car given that states specific energy sources.
Even W Virginia, the worst state I could find, having about 90% coal, gives much lower emissions for an ev than a gas car. And that’s with the current mix. It’s only getting better from here. And that’s the worst state!
