In the wake of Hurricane Sandy, all of the critical pieces of equipment were burning gasoline or diesel fuel: the pumps removing water from flooded basements and subway tunnels, the generators providing electricity to hospitals and businesses, and the cars, trucks and aircraft providing mobility. Petroleum is essential to modern society not because of some conspiracy cooked up by Exxon Mobil and its brethren. Instead, it is due to simple physics and basic math. Sandy left millions of East Coast residents in the cold and dark. If any of them have been demanding “green” energy, I haven’t heard about it. In the storm’s aftermath, the most hopeful sound of recovery is the joyous racket that comes from an internal-combustion engine burning fossil fuels.
