Electric cars
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.
About 1% of today's cars are electric[USA, 2023] - 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
The vast majority of today's electric cars store their energy in lithium-ion batteries, which contain too much cobalt to scale up.
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 less range), electric cars could be made with other battery types
Energy sources
If the electricity comes from fossil fuels, electric cars are 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.
Availability of charging

Rare-earth magnets
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.
This is true even if all energy were to come from wind turbines, which also contain rare-earth magnets.
TODO: Add the calculations & research that led to this statement.
