It would take 25% more electricity than we use today to replace all the gasoline cars on the road in the US today. That doesn't mean we need 25% more power plants, it means we just need to charge the majority of the cars at night when power demand is the lowest. Fortunately that's when most people need to charge their car.

I also don't see a full changeover in 10 years but we're only one major battery advancement from Battery Electric Vehicles being able to handle almost everyone's car needs, plus short to medium distance commercial vehicles.
