	This page is about ''passenger-owned'' electric vehicles (EVs): '''cars''', '''vans''', '''pickup trucks''', etc. For commercial semi trucks, see the page on [[electric trucks]]. For passenger buses, see [[electric buses]].		#REDIRECT [[Electric vehicles]]

	~~{{considerations}}~~

	~~About 1% of today's cars are electric<sup>[USA, 2023]</sup> - the rest run on gasoline which causes [[climate change]].~~

	~~==Types==~~
	* Battery electric vehicles (most common EVs today)
	* [[Fuel cell vehicles]] (very few models on the market today)
	~~==Considerations==~~
	~~===Battery minerals===~~
	~~{{sum\|Currently a problem\|bad}}~~
	The vast majority of today's electric cars store their energy in [[lithium-ion batteries]], which contain too much cobalt to scale up. {{x\|Cobalt mineral reserves would be depleted early-on, and the majority of cars would remain gasoline-based, even with desperate attempts at obtaining more cobalt such as strip-mining the ocean floor. See page on [[lithium-ion batteries]] for maths related to this.}} Lithium is also somewhat scarce and could be also be an issue.

	{{minor\|Every once and awhile there's some news article about some company researching / developing / investing in some battery type that will supposedly be as energy-dense as lithium-ion. But there's no guarantee it'll happen in the near future, and if it does, it'll probably be expensive.}}

	~~Scarcity is also an issue for [[hydrogen]] fuel cell vehicles (which depend on platinum-group metals).~~

	If car buyers are willing to compromise (settle for [[short-range electric vehicles\|less ''range'']]), electric cars could be made with other battery types{{x\|such as [[sodium-ion]], or somewhat less ideally [[lithium iron phosphate]]}} that are more sustainable/scalable. The main selling point is that they would be cheaper. {{qn}}

	~~<!-- TALK: work this in somewhere? or put it in [[energy storage~~#~~types]] or~~ [[~~the great battery challenge]] idk~~
	* [[lithium iron phosphate]] (somewhat more scalable)
	* [[lithium-sulfur]] (somewhat more scalable)
	* [[sodium-sulfur]] (much more scalable & sustainable)
	* [[sodium-ion]] (much more scalable & sustainable)
	~~-->~~
	~~===Energy sources===~~
	~~{{sum\|Not green enough yet\|bad}}~~
	~~If the electricity comes from [[fossil fuels]], electric cars are [[electric vehicles/fossil fuel powered\|barely any better than gasoline cars]] when it comes to carbon emissions.~~

	In most parts of the world today, electricity is generated from [[fossil fuels]]. {{x\|Consider that [[hydro]] and [[geothermal]] power are only available in a few geographic locations; [[conventional nuclear power]] is limited by scarcity of uranium-235; [[biomass waste]] energy is in extremely low supply. Whenever the local capacity of renewables is exceeded, fossil fuels make up the difference.}} For electric vehicles ~~to save the environment, we're going to need a lot more [[solar]] and [[wind]] (which comes with other [[solar/challenge 1\|challenges]]), or [[thorium\|other kinds of nuclear]].~~
	~~<!-- TODO: make a map of where in the world are hydro & geothermal power available and not already at maxed-out capacity -->~~

	~~===Availability of charging===~~
	~~{{sum\|Ongoing progress}}~~
	~~{{empty}}~~

	~~===Rare-earth magnets===~~
	~~{{sum\|Reasonable}}~~
	Efficient electric motors need strong magnets, which can only be made with certain minerals known as ''rare-earth elements'' (REEs). Luckily, REEs aren't actually that scarce. Even if all vehicles were electric, we wouldn't even come close to running out of REEs.

	~~{{minor\|This is true even if all [[energy]] were to come from [[wind]] turbines, which also contain rare-earth magnets.}}~~

	~~{{pn\|TODO: Add the calculations & research that led to this statement.}}~~
