electricity is “100% available” energy

Although much more than an ICE, electric motors are not 100 percent efficient. Chargers are not 100 percent efficient. Batteries do not take up the charge, nor discharge at 100 percent efficiency. Nor is the entire drivetrain 100 percent efficient.

Of course, missing from that laundry list is the fact that the transmission of electricity is not at all 100% efficient.

And at the end of the day, that electricity probably came from the burning of a "fossil" fuel. And if it did somehow come from wind or solar - those are not at all 100% efficient, nor anything nearly reliable.

All true, in the real world. In an ideal, lab bench, world, I make no doubt that conversion of electrical energy to mechanical work could (e.g., using superconductors in the motor) be done with awfully close to 100% efficiency. And I did use scare quotes around the expression “100%” available.

But I must quibble about “drive train” efficiency - in that no transmission is required for the EV. One less (mechanically complex) part of the drive train . . .
