Prius vs. Hummer in Environmental Friendliness

An organization called CNW Research claims in their report Dust to Dust: The Energy Cost of New Vehicles from Concept to Disposal “The Prius registered an energy-cost average of $3.25 per mile driven over its expected life span of 100,000 miles. Ironically, a Hummer, the brooding giant that has become the bête noir of the green movement, did much better, with an energy-cost average of $1.95 over its expected life span of 300,000 miles.“ Therefore, the Hummer is the more environmentally friendly vehicle. Of course the claim is bogus. What first made me suspicious was big difference in the mileage lifetimes.

Washington Post Columnist George F. Will publicized this information in his syndicated column in April 2007 (click here). I am particularly disappointed that a respected columnist and journalist like George Will would promulgate such information without proper fact checking.

The real facts are the Prius is much more energy efficiency over its life time, There are many good rebuttals to the CNW Research paper that get the facts right. All one need to do is a quick search on the web to find them. A few of the good articles are:

Sierra Club Mr. Green Rebuttal

Climate Progress

Rocky Mountain Institute.

I suppose the CNW Research article is comforting to those who drive a Hummer or dislike environmentalist. But facts are fact.
