My concern with Electric power plants is that they require an electrical charge. Available electricity is already at a critical phase now with countries like the U.S.A. having to import electricity and it is not alone. If E-engines are to have a future they must drastically improve efficiency by regenerating their own power once initially charged and diminishing battery size and usage. I think there are other options but any will be expensive to develop.I welcome the change because things clearly can't keep going on this way, but I for one would welcome continuing to evolve towards electric powerplants. They are the future and this is where the biggest room for innovation is within the auto industry today.
I do believe the technology will solve this, however. Meaning, within a decade the performance/efficiency of electric powerplants will advance to the point where people will be complaining if F1 *isn't* using them.
