if we consume the fuel byproduct, presumably we just end up with co2 in the atmosphere? It's necessary to compare the two things: 1 - we drill out more fossil fuels and burn it 2 - we convert atmospheric CO2 to fuels and burn it #2 is theoretically infinite and CO2 levels never increase. #1 is very finite and the longer we do it the higher CO2 levels increase.
