Hello, My feeling is Hybrids do give you cleaner air once built but the technology to build them creates five times the pollution that they save once built. Has anyone bothered to find out what happens to the old battery when they are worn out. that battery is very dangerous to the air and water we need to survive. not to mention the soil which we grow our food in. So the next time you want to be green find out what happens when you need to get rid of it!!!!!!! ALL OF YOU SO CALLED ENERGY CONSCIOUS AND GREEN PEOPLE MIGHT BE SURPRISED TO FIND OUT HOW NOT GREEN YOU REALLY ARE. TAKE A LOOK AT HOW THEY ARE BUILT ALSO. IF SO GOOD WHY CANT THEY BE TOTALLY MANUFACTURED IN THIS COUNTRY?( THE BATTERY THAT MAKES A CAR A HYBRID THAT IS.)ANSWERS MIGHT SURPRISE YOU.
