The Importance of Ethanol

1. This isn't true

Corn ethanol is basically just a way of converting natural gas (through fertilizer and steam) into a liquid fuel. Some have argued that we need liquid fuels, so even if it consumes more energy than it produces, as long as it is natural gas energy this is okay. But it also takes 2000 gallons of freshwater to produce ethanol, and fertilizer runoff produces nitrous oxide: 300 times as potent a greenhouse gas as CO2.
