Here’s an awesome question for all you green motor enthusiasts out there:  which car is more green, an electric Tesla roadster or a car powered by bioethanol?  Here are two points to consider by way of the Biofuels Institute:

*  The Tesla gets its juice from a power plant that is burning coal, which means it has 2.095 pounds of CO2 per kWh and can go 3.12 miles per kWh.

* The theoretical corn-ethanol E85-burning vehicle puts out CO2 according to the GREET model (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) for lifecycle emissions and is operating at the proposed new CAFE standards.

These facts by themselves don’t mean a whole lot, but when you follow them to their logical conclusion what you get is a downright shocker: as it turns out, the E85 car is actually THIRTY PERCENT GREENER (in that it generates thirty percent fewer CO2 emissions over the course of both vehicles’ hundred and forty five thousand mile life spans) than the Tesla Roadster.

I was pretty shocked to hear that myself.  Now the next time someone looks all smug in their electric car while you’re filling up on flexfuel, just look at them, shake your head sadly, and know that you’re greener than thou.
