The ethanol fueled cars sound like they should be a good idea... but if you do the math, it takes the equivalent of 4 gallons of gasoline to produce 3 gallons of ethanol. So every time you put 3 gallons in your tank, you are causing the farmer and industry to buy the equivalent of 4 gallons of conventional fuel.
The hybrid picture is also fairly unfavorable.
Money spent represents resources consumed. A hybrid costs about $5,000 per year more to run than a conventional vehicle, indicating that it consumes more resources (batteries, etc.).
