The major portion of our oil consumption comes from transportation not electrical infrastructure. But, it is a piece of the puzzle. One additional aspect people may not be considering is that if we switch our transportation from oil based infrastructure to electrical infrastructure, we will need a whole lot more electricity than the power companies have planned for.

From what I see, electrical (battery or ultra capacitor) is the most likely form of replacement for the ICE. There seems to be too many issues with hydrogen, as nice as that might be. Even then, hydrogen would power an electric engine.

The point is that each piece of the energy puzzle is important and in the case of power generation plants, we can rest assured we will not need fewer of them, we'll only need more.
