Tom Friedman wrote earlier this week in his plan to save the world by setting a $4 a gallon fuel price in the US:
I was visiting my local Toyota dealer in Bethesda, Md., last week to trade in one hybrid car for another. There is now a two-month wait to buy a Prius, which gets close to 50 miles per gallon. The dealer told me I was lucky. My hybrid was going up in value every day, so I didn’t have to worry about waiting a while for my new car.
You know what is one of the least environmentally friendly things you can do? Buy a new car, even a Prius:
As Matt Power notes in this month’s issue of Wired, hybrids get great gas mileage but it takes 113 million BTUs of energy to make a Toyota Prius. Because there are about 113,000 BTUs of energy in a gallon of gasoline, the Prius has consumed the equivalent of 1,000 gallons of gasoline before it reaches the showroom. Think of it as a carbon debt — one you won’t pay off until the Prius has turned over 46,000 miles or so.
There’s an easy way to avoid that debt — buy a used car. The debt has already been paid. But not just any used car will do.
It has to be something fuel efficient. Like, say, a 1998 Toyota Tercel that gets 27 mpg city / 35 mpg highway miles. The Prius will have to go 100,000 miles to achieve the same carbon savings as the 10-year-old Tercel. Get behind the wheel of a 1994 Geo Metro XFi, which matches the Prius’ 46 mpg, and the Prius would never close the carbon gap, Power writes.
Why does Tom Friedman hate the Earth?
