Why We Need A Gas Tax

Alec Dubro argues that fuel-efficient cars will never stop global warming:

In 1865, English economist William Stanley Jevons discovered an efficiency paradox: the more efficient you make machines, the more energy they use. Why? Because the more efficient they are, the better they are, the cheaper they are and more people buy them, and the more they’ll use them. Now, that’s good for manufacturers and maybe good for consumers, but if the problem is energy consumption or pollution, it’s not good.
