"Pretty much nothing" is an exaggeration, but they aren't wrong in stating that it isn't the ideal solution. You've pobably already seen them talk about how shitty the Lithium mines are for the environment, and if you're still getting your electricity from, like, coal plants or other environmentally unsustainable places, well, you're not emitting CEO2, but the plant that outputs the electricity that fuels the car is now outputting more. It's still better than nothing, though

My personal issue with EVs isn't so much that they aren't perfectly ecofriendly, but that the biggest pushers of EVs are still capitalists with an industry to make money. The best we have in terms of solutions is better civil engineering for walkable cities and a robust and efficient public transport system. 5 EV buses is better than 50 EV cars. Thing is, companies making EV cars still want to make money. They have no incentive to actually push for public transport (Some like Tesla seem actively hostile towards the idea), as they would make more money on 50 electric cars than 5 electric buses. Considering how much power companies have in politics, especially in the US (which is from where I'm speaking), things don't look good

I'm certain that EVs are less of an issue in, like, the Netherlands, where public transport is better, and people can just bike everywhere. Again, though, I am speaking as an ignorant American, seeing how things are playing out here. Either way, EVs are generally preferable to ICE cars, but they are a far-cry from the actual solution they are being marketed as
