(The case of Bermuda is fascinating and annoying to me. You would think that they were really well positioned to take advantage of solar, but the banks there are very conservative about financing things like residential, solar and so it's been very slow to take off, despite energy prices that are some of the highest in the world)
Generally, combined cycle plants are ~50% efficient in terms of fuel to power, energy density of bunker C is 40Mj/kg, transmission losses are variable, but figure them at 10% so it's ballpark and easy, EV chargers are about 80% efficient, car extracts 80% of the energy it draws from the battery in normal use (remember the motor isn't all that's being powered).
So there's alot of loss along the way. Some of that is solvable, some of that is improvable, but ultimately the solution is clean, cheap power so the losses don't matter.
Until we've got that, hybrid drivetrains are a good solution, provided they're implemented well.
I know you're being an asshole with the whole tires comment, but, it would be a fun bit of math to do.
