Which is better — an electric car (like, say, the Nissan Leaf) or a gas-powered car (like, say, the Nissan Juke)? There are innumerable websites to help you decide, but an awful lot of them seem to repeat the same bizarre logic.
Take, for example, the comparison page at CleanTechnica. Here we have, in the pro-Leaf column:
The benefits to…public health as a whole from not emitting the pollution that would come from burning gas.
This is immediately followed by a cost comparison, which counts (again in the pro-Leaf column) the $7500 tax credit for electric vehicles.
Sorry, but you can’t have this both ways. My friend Alice believes that when you shop for a car, you should respond to the incentives you’re faced with, and not worry about spillover effects on others. She, therefore, cares not a whit for public health benefits, but is very impressed with that $7500 tax credit. My friend Bob, on the other hand, has a highly developed social conscience. He, therefore, is very much concerned with his neighbors’ health, but correspondingly reluctant to lift $7500 from his neighbors’ pockets.
The CleanTechnica page, then, is addressed neither to Alice nor to Bob, nor, apparently, to anyone else with a coherent philosophy, but only some moral schizophrenic who cares passionately about the state of his neighbors’ lungs but not a fig for the state of their pocketbooks.
