Telling people that buying an electric car

to 不定詞

is a great way to fight climate change is

a pretty reliable way to start an argument in some circles.

People will say that you still burn fossil fuels

at the power plant instead of the engine.

over their lifespans, electric cars don't consume

gas-powered cars do — especially in the United States.

With electricity getting cleaner all the time,

they're even better than you might expect.

There are a few variables to keep in mind though,

In the US as of 2016, the average pure-gasoline

Some go four kilometers or so; others go fourteen.

But the fuel efficiency hits higher highs,

and lower lows, when we start talking about

But the major complicating factor here is electricity.

Most electricity in the US uses a combination

of natural gas, coal, and nuclear fission –

But those numbers change from state to state,

and depend on things like local natural gas sources

For example, Alaska has plenty of natural gas

and hydroelectric resources, so its power plants

create very little waste when generating electricity.

That means a full electric vehicle charge

using Alaskan electricity creates roughly

drives 48 kilometers per liter or 112 mpg.

That's roughly five times the national average,

But at the other extreme are places like Colorado,

is one of the dirtiest states. Sorry Colorado.

About half of Colorado's electricity is from coal,

A full charge off of Colorado electricity

equates to about twenty kilometers per liter (46 mpg) –

about double the national average, based on 2016 figures.

Better still, most of the country is closer

Power plants are just better at making power

One reason is that they're simply bigger.

Bigger things don't waste as much energy staying hot

And the story is similar across most of the world,

although again the details change depending on

like India or China, electric cars break even

with the average gas-powered car in the US —

90 kilometers per liter to beat an electric one.

So are electric vehicles really more efficient than gas?

unless you have some very dirty electricity.

But climate change isn't just one problem;

it's a hot mess of many problems at once.

And it'll take some pretty radical changes

from people all over the world to keep that

Before you go, you may or may not be aware

And that book… is out in paperback now.

I didn't tell you about it when it was just hardcover,

but now you can get it in value discounted,

It's a book about a girl who gets famous on the internet,

which is something I know a little bit about.

And it's also about like, space aliens, some.
