Trying to use biofuel to replace ALL sources of energy sounds pretty silly. Is anybody actually suggesting that? What about how much land would be required to replace the _gasoline_ usage with ethanol? "Each year, one acre of corn produces 551 gallons of ethanol, which is the equivalent of 386 gallons of gas." "According to the U.S. Energy Information Administration (EIA), Americans consumed 140.43 billion gallons of gasoline in 2015" 363.8 million acres to make enough corn to replace gasoline - not factoring in all the other negative externalities. A little more than 4x land area what the US uses now.
