Water Shortage will be caused by Ethanol Energy Policy

The report says that it took 2,400 litres of irrigation water to produce one litre of ethanol from maize in China. For
the same amount of ethanol from Indian sugarcane, 3,500 litres of water was needed.In the US, where mainly
rainfed maize is used, only 3% of all irrigation withdrawals are devoted to biofuel crop production, corresponding
to 400 liters of irrigation water withdrawals per liter of ethanol.
By contrast, it took just 90 litres of irrigation water to produce a litre of ethanol in Brazil from mainly rain-fed
sugarcane.

It looks like we are making things worse, not better.
