Eli5: are electric cars greener?

1.04K 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?

This is a very complex thing to answer, but it is shortsighted to see things as they are now, versus as part of a larger system that will change over time.

For example, imagine if someone said, it’s dumb to be a doctor. If you go to medical school, then your life will be studying and working 16 hours a day, make no money, and up to your neck in debt. If that was all there was to it, it would be a terrible decision to be a doctor. But over time, things fall into place and it can wind up a financially rewarding and satisfying career. You don’t expect all of that to happen right away in year one.

It takes time to develop electric cars that can run well. It takes time to develop batteries that are cleaner. It takes time to improve the electricity infrastructure system to be cleaner. You can’t change everything to perfection in year one.
