the laws of thermodynamics, combined with the prohibitive cost of electric and fuel cell technology make this a pipe dream if you're looking for a material impact on comsumption, unless you are OK with driving a papier mache deathtrap.
Drought impact is definitely not what it used to be, but it is still a reality. Crop disease is another risk, though we've thankfully reduced that some with GMO crops. There is simply too little arable land to make corn-based solutions a realistic substitute given risks and ripple effects. Other plant life shows some promise, but corn is crap.
