How much does it cost to produce one gallon of ethanol?
Ethanol production costs were estimated at $3.48 per gallon using raw sugar as a feedstock and were estimated at $3.97 per gallon using refined sugar. For these feedstocks, feedstock costs accounted for more than 80 percent of the total estimated ethanol production cost.
Fuel Prices
This makes E85 32% cheaper than gasoline. So when you factor in the cost of E85 and the mileage it yields, the cost for E85 is less than gasoline. Even in the worst-case scenario, when E85 reduces your mileage by 25%, you can save about 7% on fuel.
Unfortunately, sugar cane ethanol production in the United States is not economical. The United States does not have the proper growing conditions for large-scale sugar crops and creating them artificially would be very expensive.
Through research performed at Cornell University, we know that 1 acre of land can yield about 7,110 pounds (3,225 kg) of corn, which can be processed into 328 gallons (1240.61 liters) of ethanol. That is about 26.1 pounds (11.84 kg) of corn per gallon.
We conclude that the ethanol industry, on average, uses 53,956 BTUs per gallon to manufacture ethanol. The best existing plants use 37,883 BTUs per gallon. Next generation plants will require only 33,183 BTUs per gallon of ethanol produced.
| Product | Gallons of water |
|---|---|
| 1 gal. of gasoline | 2 to 2.5 |
| 1 gallon of ethanol | 3 |
| 1 can of fruit | 9.3 |
| 1 gallon of paint | 13 |
The disadvantages of ethanol and other biofuels include the use of farmland for industrial corn and soy growth, rather than for food crops. Also, biofuels aren't meant for all vehicles, especially older vehicles. There is some resistance from the automotive industry when it comes to adding biofuels to the market.
Fuel Economy and Performance
The impact to fuel economy varies depending on the energy difference in the blend used. 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).
The big problem is energy density – a gallon of ethanol has only two-thirds the energy density of pure gasoline.
E-Fuel explains that it takes about 10-14 pounds of sugar to make one gallon of ethanol.
What is a disadvantage of producing ethanol from crops?
The primary disadvantage of ethanol is that it requires cropland space in which to grow. Because it is derived from corn, we take up lands that could be used to grow food for ourselves or for livestock and use it grow a fuel product instead.
Higher-ethanol blends still produce significant levels of air pollution, reduce fuel efficiency, jack up corn and other food prices, and have been treated with skepticism by some car manufacturers for the damage they do to engines.
However, most cars don't run on pure ethanol – in fact, running on higher than 15-20% ethanol concentration can cause engine damage because the engine has to be adjusted to account for the differing combustion property of that concentration.
Myth No.
Today, producing one gallon of ethanol requires about 3.5 gallons of water. That's a little more than it takes to process a gallon of gasoline.
Iowa had by far the largest ethanol production capacity among all U.S. states in 2021, with an annual production of 4.7 billion gallons. That same year, Nebraska ranked second, with roughly half of Iowa's production.
Much of this growth in area and production is a result of expanding ethanol production, which now accounts for nearly 45 percent of total corn use.
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.
How long does it take to set up the plant? With permits on hand engineering and construction takes 18 - 24 months.
Premium gas doesn't provide any more power or contain better additives than regular gas, and it contains the same amount of ethanol as other grades. It just resists detonation (knock) better than lower-octane gas—nothing more, nothing less.
You can produce your own ethanol for an ongoing cost of less than $2 per gallon. If you grow your own corn, you can distill more than 300 gallons of ethanol from 1 acre of corn. If you drive less than 10,000 miles per year, you could produce all your own fuel from 2 acres of corn — and, granted, a lot of labor.
How long will 10 ethanol gas last?
Ethanol-Blended Gas: Up to 3 Months
“Regular gas,” meaning most gasoline sold at gas stations around the country is ethanol-based gas, which is typically 90 percent petroleum and 10 percent ethanol. This type of gas has a shorter shelf life than pure gasoline and typically only lasts for up to three months.
The most recent DOE study , published by Argonne National Laboratory in 2021, found that U.S. corn ethanol has 44%–52% lower GHG emissions than gasoline.
Ethanol can cause fuel injector problems - gel, clogging and rust.
The research, which was funded in part by the National Wildlife Federation and U.S. Department of Energy, found that ethanol is likely at least 24% more carbon-intensive than gasoline due to emissions resulting from land use changes to grow corn, along with processing and combustion.
A 2020 analysis by Argonne National Laboratory found that using corn-based ethanol in place of gasoline reduces life cycle GHG emissions on average by 40%.
The Environmental Protection Agency said it would set the 2022 levels for corn-based ethanol blended into gasoline at 15 billion gallons.
Ethanol. Pros: Reduces demand for foreign oil, low emissions, high octane, and can potentially be produced from waste materials; existing cars can use 10-percent blends (called E10), and more than 8 million cars already on the road can use E85. Cons: Twenty-five percent lower fuel economy on E85 than gasoline.
Ethanol-free gas offers better mileage than fuel with an ethanol mix. Even if mileage efficiency is reduced by 3%, ethanol-free gas is better for the engine. There have been reports of ethanol mixed gas leading to rusting engine parts. Ethanol, by nature, attracts water and can cause damage.
Ethanol not only allows the U.S. to extend our traditional fuel supply, but it also burns cleaner. Corn ethanol reduces greenhouse gas emissions by 46 percent when compared to gasoline. The U.S. Department of Agriculture estimates that corn ethanol's relative carbon benefits could be as high as 70 percent.
One bushel of corn produces approximately 2.8 gallons of ethanol and 18 pounds of distillers grains.
How much energy does it take to produce 1 gallon of gasoline?
The ratings are based on EPA's formula, in which 33.7 kilowatt hours of electricity is equivalent to one gallon of gasoline (giving a heating value of 115,010 BTU/US gal), and the energy consumption of each vehicle during EPA's five standard drive cycle tests simulating varying driving conditions.
One ton of potato or PPW can be produced 25.40 to 29.72 US gallons of bioethanol [34,12, 35] .
Ethanol is harmful by ingestion, inhalation or by skin absorption. Repeated contact can dry the skin resulting in the skin cracking, peeling and itching. Ethanol can depress the central nervous system, the eyes and upper respiratory tract (nose and throat).
Grain-based ethanol cuts greenhouse gas emissions significantly—by 44 to 52% compared to gasoline, according to the Department of Energy's Argonne National Laboratory. Similarly, researchers from Harvard, MIT, and Tufts concluded that today's corn ethanol offers an average GHG reduction of 46% versus gasoline.
Corn is the leading U.S. crop and serves as the feedstock for most domestic ethanol production. Corn ethanol meets the renewable fuel category of the Renewable Fuel Standard (RFS), which is limited to 15 billion gallons.
Ethanol returned to the nation's political agenda amid the oil crisis of the 1970s. By the end of that decade, a powerful “gasohol lobby” in the Senate pushed former Presidents Carter and Reagan to support ethanol.
The federal government provides an array of subsidies to increase the consumption of biofuels such as corn ethanol. The subsidies include tax breaks, grants, loans, and loan guarantees. The government also imposes a mandate to blend biofuels into gasoline and diesel fuels.
Under the Clean Air Act, E15 cannot be sold in summer because it evaporates more readily in warm weather and can worsen air pollution.
The United States is the world's largest producer of ethanol, having produced over 13.9 billion gallons in 2020. Together, the United States and Brazil produce 84% of the world's ethanol.
Can cars really run on moonshine? Only if it's really strong stuff. To power a car, moonshine—in this case, illicit homemade whiskey—must have an extremely high alcohol content, at minimum 150 proof (or 75 percent alcohol by volume), or 190 proof for best results.
Can a car run on water?
It would need equipment to split a water molecule apart and separate its oxygen and hydrogen. Then it would need to isolate each of them in separate tanks. Then you would need a combustion system that could mix and ignite them, or a fuel cell that could recombine them to make electricity.
Through research performed at Cornell University, we know that 1 acre of land can yield about 7,110 pounds (3,225 kg) of corn, which can be processed into 328 gallons (1240.61 liters) of ethanol. That is about 26.1 pounds (11.84 kg) of corn per gallon.
Vodka, by definition, is ethanol cut with water to at least 80 proof (40 percent purity). Despite its common sobriquet of "potato juice," it's actually pretty hard to make it from spuds—the tuber tends to produce more methanol (poison) than grain feedstocks, requiring additional distillation.
Poet Biorefining is the largest ethanol producer in the United States.
The corn mash is transferred to fermentation tanks and is mixed with yeast and allowed to ferment for 40 to 50 hours, which changes the sugar to ethyl alcohol and carbon dioxide.
U.S. ethanol plants are concentrated in the Midwest because of the proximity to corn production. Plants outside the Midwest typically receive corn by rail or use other feedstocks and are located near large population centers.
100 million gallon annual ethanol production capacity. Plant construction costs of $2.11 per gallon of ethanol production capacity. 40% debt and 60% equity financing.
You can produce your own ethanol for an ongoing cost of less than $2 per gallon. If you grow your own corn, you can distill more than 300 gallons of ethanol from 1 acre of corn. If you drive less than 10,000 miles per year, you could produce all your own fuel from 2 acres of corn — and, granted, a lot of labor.

How much does it cost to refine gasoline? The cost to refine gasoline varies between 40 cents and 70 cents per gallon, depending on various factors.
Is corn ethanol more expensive than gasoline?
Adding more ethanol to gasoline blends could potentially reduce prices at U.S. gas pumps because ethanol, which is made from corn, is currently cheaper than straight gasoline.
The United States is the world's largest producer of ethanol, having produced over 15 billion gallons in 2021. Together, the United States and Brazil produce 82% of the world's ethanol. The vast majority of U.S. ethanol is produced from corn, while Brazil primarily uses sugarcane.
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. (It has a higher octane, if you're interested.) Pure ethanol would be useless as fuel in the winter months.
Can cars really run on moonshine? Only if it's really strong stuff. To power a car, moonshine—in this case, illicit homemade whiskey—must have an extremely high alcohol content, at minimum 150 proof (or 75 percent alcohol by volume), or 190 proof for best results.
Technically, most any vehicle can be made to run on E85, which is 85 percent alcohol, and 15 percent gasoline.

Here's What the Carbon Footprint of Ethanol Is.
| Burning of ethanol | Carbon footprint |
|---|---|
| Driving one mile (on average) | 315 grams of CO2 emitted (when E85 is combusted) |
Usina São Martinho in Pradópolis Brazil – the largest sugar-ethanol plant in operation in the world – has achieved Bonsucro certification. Founded in 1948, the mill has an approximate crush capacity of 10 million tonnes of sugarcane each harvest.
“Your fuel is a volume thing. You've got to sell a lot of fuel to make a little bit of money off it.” “A little” as in 15 cents a gallon on average, according to the National Association of Convenience Stores. About 80 percent of the gas purchased in the U.S. is sold by convenience stores like Nordman's.
In addition to oil company executives, shareholders also reaped the benefits of high energy prices during the quarter. Since the start of 2022, Exxon and Chevron shares have risen close to 46% and 26%, respectively.
A barrel of oil equivalent has a LHV of about 35.6 kWh/gal which is very close to the 35.3 kWh/gal LHV figure for a typical gasoline. So 15% x 15% x 35.6 kWh/gal is about 0.8 kWh/gallon of actual electrical energy use.
