Dust to Dust

Finally, a study that looks at the overall environmental impact of automobiles has surfaced. (Thanks to Autoblog for dredging it up.) This article seems to confirm my hunch that hybrid environmental savings aren't all their touted to be. However, as some commenters at autoblog have noticed, these environmental costs will change as demand for hybrids increases. I agree it is likely that soon the environmental costs of hybrids will be essentially equal to their less technologically savy brethren. But only equal? That doesn't sound like the hybrids the world has come to know and love. I thought these things were supposed to be saving the earth.
