The US consumes 20 million barrels of oil per day

That's oil consumption, not gasoline consumption. Also typically you can only have 10 to 15% ethanol in normal cars.

Cut out oil not used for gasoline. Now multiply by .1 or .15% and you get how much ethanol we can use as fuel absent other changes. Now 8 billion gallons a year isn't quite a drop in the bucket any more.

to make that 4.9 billion gallons of ethanol, it took 1.6 bushels of corn......which is roughly 14% of the annual US corn crop.

That's a lot. Its also going up. And there are a number of proposals to increase it even more.

To look at it another way - Assume your data is accurate. Now assume we move 100% of corn production to ethanol. We only get about 35 billion gallons of ethanol per year, still well short of 840 million gallons isn't it?

To sum up -

1 - The portion of corn that goes to ethanol is large and rising.

2 - Don't look to ethanol to be more than a marginal part of reducing gasoline and/or oil use.
