In 2010 net imports of energy accounted for a percentage of all energy used in the US?
22% -- A+Ls
Where was wind power first used?
It was developed and used in the U.S. i believe. I suggest wind power was first used hundreds of years before the US was thought of! But this was for mechanical use, raising water and grinding corn. they are just guessing!
What percentage of useful energy in US is unnecessarily wasted?
41%-43%
What percentage of us energy is made by nuclear power?
About 19 percent of electricity
How much of the US corn crop is used for ethanol production?
As of 2011, approximately 45% of US corn production is being used for ethanol production.
Which vegetable in US is the main source of ethanol?
Corn.
Which is a use of corn mandated by the US Congress?
Ethanol production
Why do us farmers want the govt to support corn ethanol rather than sugarcane ethanol?
Because sugarcane can only be grown in a very limited area of the US, unlike corn, which can be grown over a much larger percentage of the country. Also, from a political viewpoint, there are many more corn farmers than sugarcane farmers, so they have much more influence on the legislators involved.
How much land is used in the US to raise corn for livestock?
Approximately 55 million acres, but this can vary from year to year. Roughly another 35 million acres is used for corn to produce ethanol.
Why does US import so much oil when US is the third largest producer in the world?
Because we use it for everything including the growing of corn used to make ethanol.
What is ethanol made of?
Ethanol can be distilled from any material which contains complex carbohydrate molecules. Corn is used frequently in the US; sugar cane is used mostly in Brazil. Leftover plant materials such as corn cobs and wood chips can be used, but require more processing before they are ready to be fermented. Switchgrass and potatoes are other materials which are used somewhat.
How much corn to make 1 gallon of corn oil?
Currently a bushel of corn produces about 2.8 gallons of ethanol. With better varieties that figure will increase to 3 gallons. In the near future, the corn distillate will be processed again, yielding some more ethanol.
What is most of the corn used for in the US?
Much of it is used for feeding livestock and a large amount is used in the production of ethanol. However, an amazing 44% of Illinois corn is exported (IL Dept of Ag). That is probably the majority single use for the state.
What can you use maize for?
Maize is a kind of grain used mainly to feed livestock. In the US it's called "corn". A lesser amount is used for food products like corn tortillas, corn meal, and corn chips. The sweeter kind, called sweet corn, is also a popular food item in the US.
Can existing car engines be adapted for ethanol fuel?
Your car can safely run on fuel that is up to 10% ethanol. To run E85 which is 85% ethanol your car must be modified. It can be done but it would be very expensive to make all the changes necessary. Ethanol is a solvent and will destroy common rubber seals and gaskets used in cars not designed to run it. It is highly corrosive to aluminum and other parts in an engine. And besides, why would you want to burn ethanol. Ethanol has less energy than gasoline so your fuel mileage will drop around 20 to 30%. If you are getting 30 mpg with gasoline you will get around 24-25 with Ethanol. You will also have less power burning Ethanol. And it takes corn and other food sources to make Ethanol. That causes the price of corn to go up costing us more for food products containing corn.
When gas contains 10 percent ethanol how much ethanol is in a gallon of gas?
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).
