>Cite your sources, please

we need sources for the fact an electric motor, all other things being equal, is better than a combustion engine? If you agree that people in general value the health of their lungs that alone is sufficient reason.

It's also becoming quickly a question of geopolitical resilience, running your transport system on dinosaur juice coming from regions where people blow each other up is bad in particular if you happen to be Japanese automaker Honda

> an electric motor, all other things being equal, is better than a combustion engine?

This is not the core argument. Motors maybe superior - we can agree on that. The power source (batteries) and the environmental impact they have - that has always been the core argument. [1]

Again, without sources, these are just opinions.

		Does the article you cited cost money to read? I found a description on google scholar: > Ten years left to redesign lithium-ion batteries > Reserves of cobalt and nickel used in electric-vehicle cells will not meet future demand. Refocus research to find new electrodes based on common elements such as iron and silicon, urge Kostiantyn Turcheniuk and colleagues. I notice that the article was published in 2018. So I guess we only have to wait two more years to decide if it's right or not. Will we be out of cobalt and nickel by then? I'd be happy to take a bet with you, assuming you stand by the article you cited.

		That's an atrociously written opinion piece presumeably written to cast shade on the EV industry. Full article, for others: https://sci-hub.ru/10.1038/d41586-018-05752-3 My background is global geophysical exploration, primarily for mineral resources with some dabbling in the energy domain. For a single example, this passage: `High demand and prices are already encouraging some producers to cut corners and violate environmental and safety regulations. For example, in China, dust released from graphite mines has damaged crops and polluted villages and drinking water. In Africa, some mine owners exploit child workers and skimp on protective equipment such as respirators. Small artisanal mines, where ores are extracted by hand, often flout laws.` is entirely emotive, intended to tug on feelings (which it does) but otherwise it has no bearing on the bulk of major mining that contributes to bulk of mineral processing. The tonnes of nickel and cobalt we see largely comes from big mines, big trucks, formal Occ Health and Safety regulations, etc. It also commits the usual mistake of confusing "just in time" exploration results that firm up suspected deposits with sizes and density estimates for the commodities of interest with absolute limits on what is available over the cycle of time. As demand increases further areas that are "known" (but not measured) get further technical inspection (magnetics, drill sampling, etc) and become new fresh reserves.

> This is why the left/progressive crowd is so disliked by the conservatives - they phrase any argument from an inherent view point that they assume is self-evident.
