What about airplanes? I don't think we can do a battery powered jet engine. Possibly a feasible battery powered propeller airplane someday. Airplanes have flown on fuel derived from coal in the past, so it could be done. Germany flew coal powered airplanes in WW2

We could grow corn and make fuel from alcohol. I have wondered about extracting pine resin. Throw some pine needles on a fire and you will see what I mean. Corn and pine trees grow back, and clean the air while they grow.

Before you go on a coal bashing rampage, the power running your computer right now more likely than not came from the efforts of a coal miner. Coal provides over 50% of the electric power in the US. The electric transportation solution would reduce the demand for oil, but still rely on energy from coal at present rates.
