Thanks maxume, that helped a lot.
If I have my math right, we would need a wind farm of around 118,600 square miles, or almost as large as the state of New Mexico (121,355.53 square miles) for everything. I suppose we could split it up across (for example) Louisiana, Mississippi and Alabama to leave ourselves a little room for growth (141,212.81 square miles total), but that would displace about 12,000,000 people - at least NM only has around 2,000,000 people. Think anybody would mind moving? Sheesh.
Digging a little deeper on the DOE site, I found that numbers for transportation are also there but it's a small percentage (about 2% of total documented consumption). That got me wondering - I don't see numbers for consumption by federal, state, and local governments. Granted, your average government building (think courthouse) probably isn't that bad, I wonder how prisons, military bases, and the high-power-drain facilities for numerous 3-letter agencies (C!A, N$A, etc.) factor in? If I had to guess I'd say it's less than industrial, but I'm still curious. Maybe we should set aside the West Virginia Wind Farm Co-operative too, just to be safe.
Just in case anybody missed the point of all this, let me be clear: wind power is not the answer. It's a (relatively) environmentally-friendly augmentation in combination with other sources, but that's it.
