Bio-ethanol needs water

This week the environmental news is full of reports that bio-ethanol production uses more water than was previously thought.

Many of them say that the usage is about three times higher than was previously claimed, something that may not be welcome news in parts of the World where water is in short supply.

However, it is not all bad news.  Apparently Minnesota and Iowa, for whatever reason, use less water than other states in the production process.

I wonder if making it from wood chippings, as is often the case in Scandinavia, needs more or less?
