How ethanol fuel used in our society?

Question

Question says it all :D

Answer 1

Ethanol is usually made by fermenting corn and is burned in vehicles which often use Flexfuel.  I have heard that ethanol takes more energy to produce than it makes when burned, and it is made from corn which could go to feeding hungry people or livestock.  Not to mention it has a much lower energy than gasoline, giving you lower gas milage.  I give ethanol a big thumbs down.

Answer 2

as demand for ethanol grows, more farmers switch their crops over to corn, raising all other food prices along the way.

the other thing that grows is the dead zone in the gulf of mexico as the nitrogen runoff from the fertilizer needed to grow corn makes its way down the mississippi river.

Answer 3

in my state we have ethanol mixed in our gasoline. it is made from corn the farmers grow.

Answer 4

Mostly it is mixed in with regular gasoline.  About ten percent max.  It makes it burn cleaner and keeps fuel lines from freezing in the winter.

Answer 5

Stop alternative energy programs based on ethanol.

  South America and the US used to export food. Now all that food is wasted and turned into gas that costs more per gallon, the production emits CO2 and on average uses 30 gallons of pure drinkable water (a resource that is getting scarcer on this planet see the news lately on all the drugs in your drinking water) to make 2 gallons of fuel while increasing the basic cost of food.

  ethanol is bad for the environment, the waste by product produces more CO2 as it decomposes, it smells (just stop by a ethanol plant...just imagine working there!) and they need lots of water just to cool it down so it doe not get lost in the production process.

Ethanol is hydroscopitic, meaning as it sits exposed to air it attracts water vapor. This water vapor will actually dilute the ethanol and any iron exposed to the ethanol (like gas tanks) will actually rust from the inside if not cared for.

  Big cities in south America (Mexico city, Lima)  have higher smog levels than any city in the USA why? One factor is the fact that it takes more ethanol to equal one gallon of gas.

  I bet your teacher wont want to hear this!

Answer 6

ethanol is a joke. there is no way we are ever going to mass produce it as it is now and is not as green as people try to make out. the only chance it has is if we start using some sort of algae or grass.
