AUTOMOTIVE INSIGHT: Life-Cycle Energy Use Needs to be the Way We Measure

Listen to this story:

All this talk about miles per gallon is fine and good, but it really doesn’t measure how much energy your car uses.

Everybody is fixated these days on the fuel economy of the car they drive. But mpgs only give you one third of the picture. It takes a lot of energy to build a car, and a lot of energy to recycle it.

A fascinating study called “Dust to Dust” came out a couple of years ago that looked at life-cycle energy usage. That is, it looked at all the energy a car used from cradle to grave. And the study determined that a Toyota Prius hybrid uses as much energy as a Hummer H3.

I’m not sure I completely believe the study, but it’s on the right track. We have to look at life-cycle energy usage if we want to formulate the kind of energy policies that are completely sustainable.
