How Much Has The US Ethanol Program cost?

The WSJ had an article today, about ethanol plants in the midwest shutting down (due to low demand for gasoline). One plant was recently sold for scrap-it had cost $271 million to build.
Is there an accurate number on how much money has been spent to build these distilleries? I know the ethanol program has been an economic loss since the beginning…but I wonder if we know how much has actuallybeen wasted on capitol costs (plants). It has to rank up there as a pretty large number.

Cannot answer the question but every time I fill my car with a 10% ethanol mix I lose mpg due to ethanol producing less energy than gasoline.
