Apparently, there's legistlature in my hometown to require all diesel to be 5% biodiesel by 2007, and 10% by 2010.
Way to go Portland! However, I have a concern about slowly shifting our dependence from foreign oil to ethanol/corn-based fuel sources. On the surface I think it's a great idea: it's completely renewable, eases our dependency on foreign oil and makes a great supplement for existing fuel sources.
However, what would happen if we were using corn for (caution: link to tacky HTML government site with animated GIFs) 85% of our fuel needs, then had a couple years of drought across the midwest? Would our energy situation be worse off than it is now?
I'm all for biodiesel/ethanol, but I think it needs to come from a source that doesn't rely so heavily on unstable sources we can't control (the weather).
