That's entirely false. All UFOs are unidentified until identified. A flying squirrel whizzing past your window is a UFO. Once identified it's no longer a UFO, maybe a IFA.
Good points have been made to rebuttal the Coal Power argument, but a lot of people don't understand that oil is used for far more than gasoline. The plastics, the rubbers, and the chemical polymers used to build this car, manufacture it, transport it, and sell it involve oil.
