Making your own ethanol is legal. All you need is a permit. You can produce fuel from your own crops. You can find used equipment for distilling ethanol, or if you weld, you can make your own.

Definitely not the US. Ethanol: Contains significantly less energy per gallon than gasoline. Is hygroscopic, meaning it absorbs water out of the air, which means it can damage engines due to excess water content if not handled carefully.
E-Fuel explains that it takes about 10-14 pounds of sugar to make one gallon of ethanol. When using store-bought sugar, which costs about 20 cents per pound in the US, plus the cost of electricity, the cost to produce a gallon of ethanol would be roughly equivalent to today´s gas prices in the US.
List of the Disadvantages of Ethanol
- It isn't as effective a fuel as traditional gasoline.
- It is a corrosive fuel.
- It requires a lot of cropland space.
- It is costly.
- Its use has resulted in a net emissions increase.
- It has altered food production principles.
- It is reliant on the quality of the growing season.
Ethanol alcohol is referred to as hygroscopic, which means it absorbs moisture. If ethanol remains in your car's fuel system for an extended period, it draws water from the tank, upsetting your car's fuel mix and gumming up the system. This can cause major damage to more than just your engine.
Ethanol prices, 18-Jan-2021: The average price of ethanol around the world is 0.96 U.S. Dollar per liter.
Each year, the laws require that the number of gallons of blended gasoline increase. As a result, pipelines are sending refineries sub-octane gas that needs ethanol or premium gasoline blended with it before it goes on sale. As refineries start to cut this amount of pure gas, it is becoming scarcer and more expensive.
Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn't, for numerous reasons: Ethanol is bad for cold-starting, because it doesn't burn as quickly as gasoline. There are no passenger cars designed to take E100 (but some racing cars are) so it could damage your car engine.
And lately ethanol is not even a cheaper alternative to gasoline. Since mid-December, ethanol prices have risen above reformulated gasoline prices because of the sharp drop in crude-oil and gas prices, along with a rise in corn prices. “That's the dominant reason [for higher prices].”
Recently, that price has ranged between $50 and $70 per barrel, depending on the type of crude oil purchased. With crude oil at these prices, a standard 42 gallon barrel translates to $1.19 to $1.67 per gallon at the pump. Excise taxes add another 49 cents a gallon on average nationwide.
A gallon of ethanol contains less energy than a gallon of gasoline, resulting in lower fuel economy when operating your vehicle. For example, E85 that contains 83% ethanol content has about 27% less energy per gallon than gasoline (the impact to fuel economy lessens as ethanol content decreases).
Ethanol is a combustible, toxic compound. It has many names, including ethyl, drinking, or grain alcohol. It is best known as simply alcohol and is found in drinks. Ethanol is a colorless, flammable chemical compound that is best known for its use in alcoholic beverages.
One of the alternatives, sorghum, already has a small foothold in US ethanol production, comprising the remaining 2% of the RFA's 2017 ethanol feedstock figures. The variety of sorghum which shows the greatest promise in reducing GHG emissions is sweet sorghum.
Data show that corn ethanol can reduce greenhouse gases by about 18 percent. (The ethanol currently used in the U.S. is largely produced from corn.) In contrast, cellulosic ethanol made from the sugars contained in plant cell walls, can cut greenhouse gases by as much as 90 percent.
Ethanol: Pros & Cons
- Greenhouse Gas Reduction - Corn-based ethanol reduces GHG emissions by 18% to 29% per vehicle mile traveled compared to petroleum-based fuels.
- Positive Net Energy Balance - Corn-based ethanol has a positive net energy balance of 1.06btu per gallon for 1.00btu of energy used without ethanol by-product credits.
By driving up the price of food and gas and causing costly engine damage, corn ethanol has been bad news for consumers. What's more, burning corn ethanol in gasoline releases more benzene, a known carcinogen, and other toxic air pollutants that have been linked to asthma, bronchitis and other respiratory ailments.
Moderate ethanol consumption reduces stress and increases feelings of happiness and well-being, and may reduce the risk of coronary heart disease. Heavy consumption of alcohol, however, may cause addiction and increases all types of injury and trauma.
Ethanol helps keep engines clean, too. It burns more completely and at a slightly cooler temperature than gasoline. Oxygen atoms inside ethanol join forces with oxygen molecules in the air to help ethanol burn more completely. This extra amount of oxygen also helps gasoline burn better when it is blended with ethanol.
Ethanol and ethanol-gasoline mixtures burn cleaner and have higher octane levels than pure gasoline, but they also have higher evaporative emissions from fuel tanks and dispensing equipment. Producing and burning ethanol results in emissions of carbon dioxide (CO2), a greenhouse gas.
Ethanol fuel has been lauded as a viable alternative to petroleum-based fuels, offering not only less pollution to the environment, but also a sustainable source of energy. Most vehicles run on mixtures of gas and ethanol; this mixture is common at most gas stations across the country.
Ethanol is a renewable fuel made from various plant materials collectively known as "biomass." More than 98% of U.S. gasoline contains ethanol, typically E10 (10% ethanol, 90% gasoline), to oxygenate the fuel, which reduces air pollution.
Ethanol contains roughly one third less energy than ethanol-free (also known as non-ethanol) gasoline does, which means you will get slightly fewer miles per gallon if you use E10 or E15. The fewer miles per gallon you get is small, but measurable. For E15, the amount goes up to 4-5% fewer miles per gallon.
Ethanol is hygroscopic, gasoline is hydrophobic. Water contamination in fuel can cause engine non-starting and corrosion issues. Ten percent ethanol blends can hold small amounts of water in solution, above this level a phase separation of water and ethanol mix separates from the gasoline.
Ethanol contains about one-third less energy than gasoline. So, vehicles will typically go 3% to 4% fewer miles per gallon on E10 and 4% to 5% fewer on E15 than on 100% gasoline.
