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.
There are a lot of used cars out there that top 30 mpg, and more than a few that reach into the 40s.
