This immediately calls in suspect the math as these are the mileage numbers expected from trucks, not cars. If they can't get the mileage right, how accurate could the water usage be? |
14.28 MPG of gasoline? The article isn't talking about gasoline consumption, it is talking about water consumption. So all three of your conversions should be "of water". The difficulty here is that in neither case is the water directly consumed by the vehicle, but in the process of getting its fuel, so it is hard to see the impact.
It is important that we really explore the impact of switching to plug-in hybrids before doing it. Unexplored solutions rarely solve our problems.
