Ya'll talk about the pollution a certain vehicle produces. Now I don't know how to word this well, but it took a lot less polution at the factory to prduce my 1998 than it does an 09 hybrid. So to me mine has paid off it's initail pollution production and every year hereafter is just the pollution from tires, oil, and fuel. Now the newer hybrids, taking, more metals, batteries, etc. to produce will have to run longer to pay thier production pollution. So why not adapt what we have now (5 yr and older), to hybrid, regenerative braking vehicles with used scrap metals and such? I hope someone understand what I am trying to convey, I am just a stupid mechanic. Now to the power grid, if our wonderful government would have invested the 10 million into better power production/ distribution instead of studying if cow and pig farts have a big impact on the ozone we'd be further along on that subject wouldn't we.
