I’m all for a regional-specific energy solution. Petroleum makes sense in places – like Texas – where petroleum exists. Less so in Nebraska where it’s easier to grow crops than dig for oil.
Despite being more renewable than petroleum, ethanol has it’s own problems. It’s a little cheaper per gallon than gasoline (bigger subsidies?), but mpg drops.. And now reports are coming out that ethanol factories are some of the biggest polluters in the midwest (Des Moines Register, Norwegianity).
