I just came across this graph in todays The Pioneer newsletter: do you see the obvious mistake in this comparison?
Yes: gas can be burned only once compared to a battery that provides "range" over and over again.
What they should have done: somehow include the range driven into the water consumption.
- a battery that drives 200.000km takes 500l of water to be produced = 0.0025l / km driven
- a gas car uses 80l of gas for 600km. Producing this gas costs 240l of water. 240l / 600km = 0,4l / km driven
So there is no case at all for the hypothesis that EV are wasting water.
And: there are two more methodological errors in this graph.
I wonder: is this just stupidness on the side of The Pioneer or are they trying to make a case against EVs?
