> If we compare average emission per mileage per car over the whole lifetime EVs are just as bad as any other car. That sounds totally outside the realm of reason. Please do cite some third-party sources.

Sounds reasonable to me. Embodied energy. One example, it takes a heck of a lot of energy to mine and process all that copper that goes into the motor windings. Another, it takes a heck of a lot of energy to mine and process all that lithium that goes in the batteries. Plus, where is the electricity comming from to charge them? Here in Montana, that generally means coal, burned hundreds of miles away and transported at great loss.

  But when the coal plants get shut down and replaced with less polluting options, all electric cars in the state will instantly become less polluting. You do know that the car industry only uses a fraction of a fraction of all electric motors created, right? And the stuff dug out of the ground doesn't mystically disappear, it can still be recycled. Coal and oil will actually just go poof when it's used. It can never be used again.

They can't because it's not true. The only way to find a third-party source to back that up is either use the one Swedish(?) study, which has been refuted by its original authors or some really ancient source with old data. Depending on the way a country produces most of its electricity, EVs will outperform ICEs in emissions in just a few years. And that's mostly ignoring the emissions from drilling oil, refining it to petrol and moving said petrol to stations.

This wasn't meant to be a scientific publishing so no I'm not gonna back this up with any source. Do your own research or simply skip the part of my comment if you think its wrong. And to all the people commenting below. It doesn't even matter if EVs are better. Even if they have half the emission to a normal car. Reusing a existing car is almost certainly still better. Also no one really know what the lifespan of any modern car is. If you assume cars follow the trend of anything else then EVs will probably be obsolete after 5 years by the time we have 50% EVs on the road. Building a car EV or not that last 10, 15 even 20 years outperforms in emission. Also my main point was that humanity should reduce cars that aren't moving that would reduce pointless emission.
