As for specific plans, Cischke said all vehicles in America should be E20-capable (E20 is fuel that is 20 percent ethanol and 80 percent gasoline) and that half of the vehicles should also be able to burn E85.

No time like the present, eh?This is a huge country, and we have a lot of natural resources and a lot of the waste that that we could convert to energy. We shouldn't squander that. ... It takes 10 years to turn around the car parc. Now it's even longer. With the recession, people are holding on to their cars longer. So if you want to do something 10 years from now, you better start planning today.
