Ethanol and Natural Gas

• Ethanol And Natural Gas
• Nearly 95 of U.S. ethanol distilleries use
  natural gas boilers
• For every 1 billion gallons of ethanol produced,
  an estimated 28 billion cubic feet of natural gas
  would be consumed, not including increased
  fertilizer demand
• About 96 of the corn planted in the U.S. depend
  on fertilizers
• Fertilizers consume more than 3 of U.S. natural
  gas use
• It takes about 33,000 cubic feet of natural gas
  to produce one ton on nitrogen fertilizer
