XKCD comic, described below.
Transcript

[White Hat, with his palm raised, is talking to Cueball.]

White Hat: Electric motors and gas engines each have their pros and cons.

White Hat: On one hand, electric motors are cleaner and more efficient. On the other hand, electric motors are more powerful.

White Hat: So it's hard to say which is better overall.
