Ethanol is a type of biofuel made from corn. Big science is starting to agree that ethanol production is hurting, not helping the environment.
So why do we continue to require its use in cars and trucks? Why is most ethanol made of corn? It is a high-octane fuel that generates more power in higher . When I first looked at the environmental impact of corn ethanol, I thought it was simple: Growing an acre of corn for fuel means you have to grow another acre elsewhere for food, which ultimately . By suspending unwise renewable-fuel standards, the Environmental Protection Agency could divert vast amounts of corn from inefficient ethanol production back into the food chain. That mandate hurts consumers, is bad for the environment and does effectively nothing to reduce America's need for foreign oil.
Corn is one of the easiest plants to ferment and distill because of its high sugar content, but that does not mean that fermenting other plants to create an alternative ethanol fuel is impossible.
I think the primary flaw in the ethanol program is that it ignores all the environmental issues, and is in existence only because a lot of scientifically illiterate people wanted to do something to help out farmers.
Starch is a complex carbohydrate. You see, ethanol is a bio-fuel and is grown, what the EPA means by fewer emissions, is that in the act of growing corn kelp or whatever they use, the plants take in some carbon dioxide and expel some oxygen.
That's according to a study just released from the University of Michigan, which says that crops used to make biofuels only about 37 percent of the carbon that is later released into the atmosphere. (The ethanol currently used in the U.S. is largely produced from corn. Beyond its positive environmental impact, ethanol can also enhance a vehicle's performance. The effect that increased ethanol use has on net CO2 emissions depends on how ethanol is made and whether or not indirect impacts on land use are included in the calculations.
The New York Times stated that E10 gasoline, which is the gas we use in America, actually gives you 2-3 miles per gallon less than gasoline.
In addition to the effect of latent heat of evaporation, the .
E85 (or flex fuel)—a high-level, gasoline-ethanol blend—is less volatile than gasoline and low-level ethanol blends and results in lower evaporative emissions. The Obama administration last week gave the green light to corn ethanol as a low-carbon renewable fuel - in apparent contradiction to California's declaration last summer that the biofuel's . The law obliges fossil fuel providers to mix in biofuel, mainly biodiesel from oilseed and ethanol from corn. For example, EPA estimates that, including land use change emissions, corn ethanol only offers a 21% greenhouse gas (GHG) reduction compared to gasoline.
As Dr. Anti-ethanol advocates also like to pick on corn. Currently, we use approximately 40 percent of corn grown in the U.S to create ethanol, and 36 percent to feed animals. The Joint Committee on Taxation estimates that between 2015 and 2024, Americans are on the hook for $26 billion in subsidies. The actual burning of ethanol produces emissions just as dangerous for the environment as gas!
We need to be selecting food products free from high-fructose corn syrup.
In light of the strong evidence that growing corn, soybeans, and other food crops to produce ethanol takes a heavy toll on the environment and is hurting the world's poor through higher food prices, consider this astonishing fact: This year, more than a third of the U.S.'s record corn harvest of 335 million metric tons will be used to produce corn ethanol.
Taxpayers are no longer directly subsidizing ethanol producers, but the Renewable Fuel Standard requires retailers to blend about 13 billion gallons of corn ethanol a year into the gasoline they sell to the public.
Ethanol only has about 2/3 the energy content of gasoline, meaning it simply cannot provide the same amount of power per . And by driving up the price of food, corn ethanol is also costing all of us money - by increasing the cost of federal programs like food stamps and school lunches. The growth of corn requires gallons of water as well as cropland, that could be preserved as wetlands.
At least in the short-term, the corn-residue biofuels release about 7% more greenhouse gases than traditional fuels, according to a federally funded, peer-reviewed study that appeared in the journal Nature Climate Change last month.
