Virtual water refers to the amount of water used to produce goods and services - agriculture accounts for 70% of global fresh water withdrawals. Even a modest 5% increase in biofuel production for road transport by 2030 could amount to at least 20% of the water used for agriculture. Ethanol was Wisconsin's top export in 2012, and since virtual water is contained in exports, Wisconsin's water supply is affected by the amount of ethanol exported.
