To understand how massive the electrification transition is, consider this:
USA annual electricity consumption: 4 trillion kilowatt/hours.
USA annual oil consumption: 12.4 trillion kilowatt/hour equivalents. (7.3 billion bbl @ 1700kwh/bbl.)
And 2/3 of all petroleum consumption is for transportation.
So 8 trillion kwh equivalents, or double the current grid capacity could electrify. Electrification is massive. It's literally oil 2.0 in every essence.
