Wondering if anyone knows if current state of manufacturing, maintaining, and disposing batteries actually is actually more ecological than using gasoline? I'm sure the potential of batteries to be more ecological and efficient is there, but the general assumption seems to be that they are already there and I'm not too sold on that idea yet.
In release terms, you are not turning your store of energy into a mix of vapours, gases and particulates on every cycle and adding them to street level atmosphere, so that is an immediate bonus that batteries would seem to win on, especially in the built environments in which we live. Getting and processing lithium and silicon are big messy industrial processes, but so is getting and processing oil and you need a lot…
This is sort of a point of contention at this point in time however. As you stated:

This would be the longer term benefit of battery powered cars. Some countries have already made progress. And unless you're driving a Tesla and only charging it as there Supercharging stations, its not completely sunlight powering your wheels. It currently comes with the ecological impact of harvesting coal, burning it and etc.
