Cash for Clunkers:A clunker that travels 12000 miles a year at 15 mpg uses 800 gallons of gas a year. A vehicle that travels 12000 miles a year at 25 mpg uses 480 gallons a year.The government claims 700000 vehicles were exchanged so thats 224 million gallons saved per year.That equates to a bit over 5 million barrels of oil.To put this perspective 5 million barrels is about 5 hours worth of US consumption.More importantly 5 million barrels of oil at $95 per barrel costs about $475 million dollars.The government PAID $3 BILLION to save $475 million.What is the ROI ?Do you think it was worth it?
