Cleantech and EV Myths Debunked | The Energy Collective

‘Electric cars aren’t green’ is a great bit of counter-intuitive headline bait, but it’s bad maths. This is how the argument goes, again and again:

Electric cars have higher manufacturing emissions than normal cars. Electric cars also use electricity that has its own footprint. And put together these two factors are a ‘dirty little secret‘ that negate any climate benefit of electric cars!

No. Let’s clear this thing up once and for all.

It’s all about the juice
One of the most irritating things about articles discussing electric car emissions is the way it’s always very black and white. In one corner you have the ‘zero emissions’ brigade and in the other the ‘worse than combustion engine’ crew.

But as ever, real life comes in shades of grey.

The reality is that even after you account for the bigger manufacturing footprint of an electric car it is all about the fuel mix of the power you use, the ‘juice’ if you will.

Using coal powered electricity electric cars do nothing to cut emissions, using natural gas electricity they’re like a top hybrid and using low carbon power they result in less than half the total emissions of the best combustion vehicle, manufacturing included.

In our recent study ‘Shades of Green: Electric Cars’ Carbon Emissions Around the Globe‘ we calculated grid powered electric car emissions in twenty countries. But we actually had data for quite a few more countries we didn’t include.

So let’s break out the data and put this thing to rest.
