What is ethanol ?

Ethanol, or ethyl alcohol. It is the same alcohol found in alcoholic beverages, but ethanol also makes an effective motor fuel. There have been decades of motor fuel application experience in the United States and other countries with ethanol.[pic 1]

What are ethanol's characteristics as a motor fuel ?

Ethanol has a lower energy content than gasoline. That means that about one-third more ethanol is required to travel the same distance as on gasoline. But other ethanol fuel characteristics, including a high octane rating, result in increased engine efficiency and performance.

What new ethanol sources are being pursued?

More American states and foreign countries are becoming ethanol producers, employing traditional crop feedstocks and processes. In addition, new technologies for producing ethanol from agricultural, forestry, and municipal wastes and residues are the focus of major research and development efforts around the world. Future ethanol production projects are being planned in California using agricultural crops such as sugar cane, and, eventually, various waste and residual feedstocks when technologies for processing these materials become commercially available.

Let´s move on to the uses of the ethanol for instance, as you can see on the screen, the ethanol fuel use in the U.S. has increased since 1992.

The trigger of this increase is simple, to contaminate as little as possible.

Ethanol fuel is use mostly in Brazil and USA (ppt) I would like to point out that these two countries were responsible for 87,1% of the wordl´s Ethanol fuel production in 2011.

It´s clear that the ethanol as a fuel has as a goal to help the environment replacing other fuels that contaminates and damages the environment.

Another purpose of the ethanol as a fuel is to save money. It has substantial economical advantages it also has disadvantages, however, I only can say this because of my partner will talk deeply about this topic.
