An interesting fact I learned is that internal combustion engines are so inefficient that you could charge an average electric vehicle using a coal powerplant, and even with all the energy lost to transformers, power lines, charging, etc, it'd still be more efficient than an average gas powered car, even if you ignore the entire petroleum refinement and distribution process.

@malwaretech Yeah. And that demonstrates how amazingly energy dense gasoline is; even with all of that inefficiency, gas cars (and likewise ICE airplanes, and the like) can easily have range that far exceed electric with motors that run into the high 90's percent efficiency.

They don't call oil black gold for nothing. Even when used incredibly inefficiently, it still pack in more energy per unit volume or mass than anything else practical to use.
