Crunching the Numbers...

Since most of us involved in promoting sustainable development are big fans of hybrid vehicles, I couldn't resist posting Clark Williams-Derry's recent post from Gristmill where he claims that "buying a new Prius is a fairly expensive way of reducing your environmental impacts." Now, Clark's not dissing hybrids in general or the motivation behind buying one; rather, he does a nice job of outlining a variety of means we can all take to fight air pollution.
