    All of that is wrong except the bike or public transportation:

    Lithium is not rare and is largely mined in areas with no life at all. The US gets most of its lithium from the Atacama Desert in spots where there has never been recorded rain. Cobalt is more rare but that is being phased out in newer batteries.

    As for emissions, an EV is better over its lifespan even if it is charging up from 100% coal energy. The breakeven point for that is about 85k miles. With your typical energy mix, it is closer to 20-30k. Even buying a used car does not win when it comes to emissions over its use unless you are planning on driving it less than 85km.

    For electric planes, they are already starting to do smaller ones with a short range. Solid state batteries will allow for much larger ones.

    Nuclear is not the most green energy source. It is significantly better than fossil fuels but it is still pretty far behind both solar and wind with energy storage.
