I can’t find the video clip now, but a politician and an automotive executive are displaying and expounding upon the virtues of an electric car to a group of people, apparently media. They show off the features of the car and demonstrate how simple and easy it is to plug it in for recharging.
A member of the audience asks, “Okay, very nice. And what is it that replenishes the battery in your car?”
The automotive exec looks at him as if he was the village idiot and replies, “Well, this charging station right here replenishes the battery.”
The guy responds, “And that station is powered by our local grid, which gets 90% of its electricity from burning coal.” The car people say nothing, looking at him as they would if he just killed their puppy.
