RE: Are hybrids worth the extra-cost?
Are they worth the cost?
No.
"As gas prices climb though, consumers can earn back that hybrid penalty over a shorter period of time"
Yeah, 3.7 years instead of 5, and that's only if you compare the Prius to a Civic, and, as jim77kahn noted, doesn't take in the cost of battery replacement or maintenance.
Also, does the claim that if everyone switched to hybrid or electric vehicles we could reduce greenhouse gasses 50% take into account the greenhouse gasses used to produced and ship the vehicles, included the extra emissions used to produce the hybrid and battery technology, as well as the increase in greenhouse gasses required to produce extra electriciy?
