What is ethanol? It is an alternate fuel source made from plant sugars that replaces gasoline as a fuel source. Ethanol is a high-octane, liquid, renewable energy source that is biodegradable and does not contaminate water. The higher the octane level of a fuel, the slower it burns, which makes ethanol a good fuel source. While some aspects of ethanol are debated, such as the energy required creating it, in comparison to the energy it produces, it is a cleaner energy source that some vehicles are currently able to use, and which more vehicles will be able to use in the future.
How is Ethanol Made?
Ethanol is made from plant sugars. In the United States, ethanol is most often made from corn and grain products through a fermentation and distillation process. The process is similar to the one used for making alcohol or "moonshine". Grain starches are mixed with water and fermented using heat and enzymes. The result is a fuel that is 100 percent pure. Some farmers are adding ethanol production to their existing businesses, while others are designed strictly for creating ethanol. While grains are the primary source, some ethanol comes from wood waste, cheese whey, and other wastes from sucrose, potatoes, breweries, and other food and beverage wastes. Commercial production of ethanol creates most of the product, but it is possible for individuals to make their own ethanol.
Benefits of Ethanol
The benefits of ethanol are many. Because it can be made from waste products, it helps reduce landfill waste. It also creates a use for waste that is otherwise not used. Such as wood chips from a logging mill or left over fruit skins at a juicing plant. In addition, because it is biodegradable, ethanol E85 does not create water pollution, and helps reduce greenhouse gas emissions, it is a much more environmentally friendly fuel source. Ethanol also helps reduce the dependence on other energy sources, as it is easily made domestically. Further, because it is made from plant sources, as opposed to fossil fuels, it is an easily renewable energy source. When ethanol is added to gasoline instead of additives, it helps reduce the burn rate of gasoline without the harmful side effects of traditional additives. This also reduces the amount of carbon dioxide created.
Using Ethanol in your vehicle.
Whether or not you can use ethanol in your vehicle depends on the percentage of ethanol mixed with gasoline. Most vehicles manufactured after 1980 can use a gasoline/ethanol blend of 10% or less ethanol. Above this level, the vehicle must be specifically designed for its use or adapted to use ethanol.
Is Ethanol Efficient?
Studies show contradictory results regarding the ratio of energy used to create ethanol, and the energy saved by using ethanol. However, numerous reports state that ethanol is highly efficient, producing much more energy than what it takes to create the product. In addition, because it can be made from waste products, farming businesses can add ethanol production to their existing business. Other commercial endeavors are in production to create ethanol from other waste products not directly related to farming, thereby offering a use for wastes that would otherwise go through waste management systems or into our landfills. Despite conflicting reports, the benefits of ethanol as a renewable energy source and one that can dramatically reduce waste and pollution will likely lead to ongoing research and use of the product.
Using Ethanol we can finally stop paying our American farmers not to grow crops and instead let them grow our freedom from oil and coal dependence. Although Ethanol isn't the greatest solution to prevent greenhouse gas effects, its one of the best current solutions we have.
We need to lead by example and force our economy into an ethanol society. We can all do our part by buying E85 ready cars and running ethanol when it becomes available in our local areas.
Together in numbers we can achieve anything.
