The outputs are the same as the inputs.
When you burn the gas it creates, the 'waste' released by your car gets used to make your next tank of gas. Its like recycling.
The emissions are the same as oil from Iraq, but those emissions are cleaned up when the next generation of bacteria go to work making more gas.

Time for class, will be checking this thread compulsively later on.
That's how I understand it, yes. The net result would be exactly zero, but the facility where the stuff gets made will be hooked into the grid, so their lights, temperature control, and other stuff will be partially dependent on coal burning power plants. Same as the factories where solar PV panels are made, or wind turbines, or wave generators, or anything else that is made from precisely constructed pieces.Edited by willis888 - 1/18/11 at 10:40am
