I wonder how many tons of CO2 are emitted in processing the materials and building the Prius compared to making a Civic/Jetta/Corolla. I'm betting it's quite a few more additional tons of CO2, and that it will take quite a few years for the sum total of CO2 emitted by the Prius to be less than that of the Civic. Does anybody have some good estimates?jonnythan:A Civic puts out ~5.5 tons, the same as a Jetta or Corolla.
A Prius puts out about 3.4 tons per year.
If you're going to seriously tell me that all of those numbers are really about the same, then we're going to have some words![]()

I don't have the link handy, but I've read an interesting comparison of actual energy consumption and generation and CO2 emissions of various types of electrical generators over their entire life cycle. Photoelectic cells came out very badly --- so bad in fact, that one would be better off just sucking coal generated power off the grid rather than trying to power up your house with photoelectrics --- both in terms of cost and also in terms of total CO2 emissions. In other words, the manufacture of photovoltaic generators generates more CO2 emissions than they eliminate over their entire 15 or 20 years of operation.
IIRC, wind powered systems had the highest net energy payback over their life cycle A good wind powered generator will deliver about 40 times more energy than was used to build it. Nuclear power plants only generated about 12 times as much energy as would be needed for the fabrication, operation, and decomissioning
