Eli5: are electric cars greener?

1.06K viewsEngineeringOther

Clarkson and others always ask the question, ‘where does the electricity come from?’

There are other stats that say it’s only better after a certain amount of miles driven or that the Lithium quarries produce significant amount of pollution.

What and where do these claims come from, how true are they and how false are they?

Greener than what? Gas stations and quick oil change shops? I hope so!

EVs are designed to use less energy per mile, even ignoring the powertrain. So there are regenerative brakes, low rolling resistance tires, careful aerodynamics, etc. Even sporty EVs can be efficient.

Even if you are driving the least efficient EV and you charged from the dirtiest power plant, there is still the advantage that emissions are at the plant rather than on the street.
