Is Ethanol From
Corn The Answer To Our Disappearing Oil Supplies?
Some people claim that we can solve global warming and the
problems caused by peak oil by burning ethanol made from corn (and other
Here are several good reasons why they are wrong - why biofuels
(ethanol made from corn) won't work:
a) Creating ethanol this way will
use up vast amounts of our corn supply. The corn needed for one tankful of
ethanol could feed one person for a year. In Iowa in the USA, 25 ethanol plants
are now operating, and 30 being built or planned. Once built these plants will
consume half the state's crop of corn. The prices for sugar, corn and wheat are
rising because we are using these foodstuffs for fuel. A huge chunk of world
grain consumption is now going into american petrol tanks. This will result in
greater starvation in a world where there is a continuing and (because of global
warming) developing food shortage. The global lack of fresh water (caused partly
by the increase in the number of bathrooms being built, the number of people on
the planet, the increasing demands of providing water for increasing numbers of
cattle, the increasing pollution of our water supplies and global warming) will
make growing crops even more difficult. And will also result in higher prices
for basic food stuffs.
b) It costs more in terms of energy to get the
fuel than it delivers. There are energy costs in building and running tractors,
and moving the corn around. You have to include the energy needed to plant the
corn, water it, harvest and turn into alcohol. Around 131,000 BTUs are needed to
make a gallon of ethanol but that gallon will only produce 77,000 BTU. This
means a loss of 54,000 BTU for every gallon of ethanol produced.
Burning plant based ethanol still contributes to global warming.
Clearing rainforests to increase the land available for the cultivation of palm
oil is bringing ecological disaster for countries such as Indonesia and
Malaysia. And it is adding to the global warming problem.
