it takes 1.5 gallons of fossil fuel to produce 1 gallon of ethanol.
I AM NOT SURE ABOUT HOW MUCH SUGAR CANE IT TAKES, BUT IT TAKES A 5X7 AREA OF CORN TO PRODUCE 1 GAL OF ETHANOL.
For every gallon of gas containing 10% ethanol (referred to as E10 gas), it will contain 1/10th gallon of ethanol (about 12 ounces by volume). Ethanol is primarily used to oxygenate the gas and replace the chemical MBTE, which pollutes groundwater. HOWEVER, since most ethanol in the US comes from corn, it is important to note that using ethanol in gasoline causes GREATER pollution than just gasoline alone. This is because it actually takes more energy to produce corn based ethanol than is extracted from it. Until better technologies for ethanol production are available (e.g. algae), it is best for the environment to avoid gas containing ethanol if possible (some states mandate it).
Ethanol produces around 80% by fermenting 100g of sugar produce.
The weight of one gallon of ethanol is 2.987 kilograms. This is equal to 2,987 grams or 6 pounds 9.352 ounces.
Zero as you can not make a gallon of gasoline from water.
Around 6 lbs. Depends on temperature and elevation.
Gasoline enriched with ethanol contains more oxygen - so it burns cleaner and much faster than regular gasoline. Which means it increase the power of your car.
The density of ethanol is 0.789 g/cm3, or 0.789 kg per liter.There are 3.7854 liters per gallon, so 1 gallon of ethanol weighs 2.987 kg.There are 2.2046 lbs per kilogram, so 1 gallon of ethanol weighs 6.584 lbs.Compare that with the weight of 1 gallon of water: 8.3454 lbs
E85 is a mixture of 85% ethanol alcohol and 15% gasoline. 1 gallon of gasoline equals 5.8 to 6.5 lbs 1 gallon of ethanol equals 6.59 lbs. The weight of ethanol is approximentally: 7.46 lbs to 7.565 depending on the composition of the gasoline used in the E85.
There is not one constant answer to this. The market on ethanol changes every day. See the link to the Ethanol Market page below to follow up today's prices and recent trends.
Expect around a 15% decline in fuel mileage over conventional gasoline. Ok, so if I'm paying $4.00 / gallon for 10 % ethanol gas and loosing 15 % mileage that means if I can find 100 % gasoline with no ethanol at $4.60 / gallon I'm getting basically the same thing. So if I pay $4.10 / gallon for real gas without ethanol, I just saved $.50 / gallon over the ethanol low output gas. This should make shopping allot easier, as long as the stations are required to post how much ethanol they are selling versus real gas.
