Do you think ethanol is better?

Question

Ethanol Makes Gasoline Costlier, Dirtier

by Jerry Taylor and Peter Van Doren

Ethanol is economically competitive now. According to a 2005 report issued by the Agriculture Department, corn ethanol costs an average of $2.53 to produce, or several times what it costs to produce a gallon of gasoline. Without the subsidies, costs would be higher still. A study last fall from the International Institute for Sustainable Development found that ethanol subsidies amount to $1.05-$1.38 per gallon, or 42 percent to 55 percent of ethanol's wholesale market price.

Answer 1

I don't know about Ethanol but I'm all for Bio Diesel

Answer 2

No, because it's inefficient since it takes more energy to grow and distill the ethanol from various crops than the ethanol actually produces. Instead of all this research on ethanol, this funding should be focused on developing other more efficient alternative fuels such as hydrogen.

Answer 3

Ethanol is an alcohol-based alternative fuel produced by fermenting and distilling starch crops that have been converted into simple sugars. Feedstocks for this fuel include corn, barley, and wheat. Ethanol can also be produced from "cellulosic biomass" such as trees and grasses and is called bioethanol. Ethanol is most commonly used to increase octane and improve the emissions quality of gasoline.

Ethanol can be blended with gasoline to create E85, a blend of 85% ethanol and 15% gasoline. E85 and blends with even higher concentrations of ethanol, E95, for example, qualify as alternative fuels under the Energy Policy Act of 1992 (EPAct). Vehicles that run on E85 are called flexible fuel vehicles (FFVs) and are offered by several vehicle manufacturers. See the ethanol vehicles page for more information on FFVs.

In some areas of the United States, lower concentrations of ethanol are blended with gasoline. The most common low concentration blend is E10 (10% ethanol and 90% gasoline). While it reduces emissions, E10 is not considered an alternative fuel under EPAct regulations. For more information on E10, see the ethanol blends page.

Ethanol Benefits



E85 is easy to use and handle - E85 fueling equipment is slightly different and of similar cost to equipment used to store and dispense petroleum fuels.

In some cases, it may be possible to convert your existing petroleum equipment to handle E85.

Using E85 reduces petroleum consumption - Use of E85 will reduce a fleet's overall use of petroleum and replace it with a renewable-based fuel produced ("grown") in the United States.

E85 is good for the environment - Beyond operational ease, E85 offers considerable environmental benefits. To learn more about fuel economy, greenhouse gas scores, and air pollution scores for individual vehicles, go to the U.S. Department of Energy/U.S. Environmental Protection Agency's on-line Fuel Economy Guide.

You can search for E85-fueled vehicles by selecting "flexible-fueled vehicles" in the "Select Vehicle Type" pull-down menu. Once you are there, select individual vehicles to get fuel economy, greenhouse gas, and air pollution details.

Flexible Fuel Vehicles (FFVs) are available and affordable - FFVs specifically designed to run on E85 are becoming more common each model year, and FFVs are typically available as standard equipment with little or no incremental cost. See the current model year FFVs.

FFVs have flexible fueling options - FFVs may operate on gasoline, and, in fact, most of the 4 million FFVs on US roadways do today. Although that is not a positive from an E85-use standpoint, it does underscore the flexibility FFVs offer fleets. When E85 is not available, or an FFV travels outside the fueling network, a driver may simply fuel with either fuel as the situation dictates.  



Ethanol Market



Many vehicles on the road today can run on blends of ethanol and gasoline—most on lower-level blends such as E10 (10% ethanol and 90% gasoline), and many on higher level blends such as E85 (85% ethanol and 15% gasoline). Because of the abundance of ethanol-compatible vehicles, the future is bright for ethanol as a fuel.

Most of today's commercially available vehicles can run on blends of E10, which is mandated in some areas of the country to act as a fuel oxygenate to improve air quality.

In addition, many newer vehicles can use E85, which qualifies as an alternative fuel under the Energy Policy Act of 1992. Vehicles that can run on E85, gasoline, or any mixture of the two are called flexible fuel vehicles (FFVs). FFVs are widely available and include sedans, minivans, sport utility vehicles, and pickup trucks. More than 5 million FFVs have already been sold in the United States, although many of the buyers remain unaware that they have the option to fuel with E85. See the ethanol vehicles page to learn more about FFVs. You can also identify an FFV by the vehicle identification number.

General Motors recently announced a new E85/FFV campaign, "Live Green, Go Yellow." Learn more about this marketing campaign by visiting their Web site.

Because of limited crude oil supplies and refining capacity, and rising concern over environmental degradation, there is a good market outlook for ethanol. Ethanol can be produced not only from corn, barley, and wheat, but also from cellulose feedstocks such as corn stalks, rice straw, sugar cane bagasse, pulpwood, switchgrass, and municipal solid waste. Because of the variety of feedstocks that can be used, ethanol offers tremendous opportunities for new jobs and economic growth outside the traditional "grain belt."

Currently, most E85 fueling stations are located in the Midwest, but infrastructure is growing nation wide. FFVs can fuel at these stations today. Check the AFDC's Alternative Fuels Station Locator to find E85 fueling in your area.

Answer 4

It's a net energy loss that will cut into global food production.  Not a large scale solution.

Answer 5

No,  Its actually more harmful to the environment. 1. the increase in emmisions. (harvesting, transportation to mills, then to the plants, then finally to the consumer).  as well as you are still burning gasoline. 2. to grow the corn you have water polution issues that needs to be addressed, fertilizers and pesticides. 3.  Up goes the food prices.  The reason the cost of fuel is so high is greed.  the oil companies knows that the people is going to pay whatever the price they want, and they know that congress (both parties, Dem's and Rep's, both houses) are not going to do anything about it.  There is tech. out there that will allow semi's to run on veg.oil but you need ethanol to thin it down. Wasn't there some tech. during WWII, for vehicles and then right after the war that tech. dissapeared? 4.  Sugar is better for ethanol, cheaper to produce into ethanol, but once again you have the water/land pollution issues to address.  plus it will drive up the food cost

Answer 6

Read this and you tell me ,Ethanol was suposed to aid conservation ,and instead replaces biodiverse forrests full of Fauna into monoculture desserts ,suseptable to plagues devoid of practically all life

The irony here is that the growing eagerness to slow climate change by using biofuels and planting millions of trees for carbon credits has resulted in new major causes of deforestation, say activists. And that is making climate change worse because deforestation puts far more greenhouse gases into the atmosphere than the entire world's fleet of cars, trucks, planes, trains and ships combined.

"Biofuels are rapidly becoming the main cause of deforestation in countries like Indonesia, Malaysia and Brazil," said Simone Lovera, managing coordinator of the Global Forest Coalition, an environmental NGO based in Asunción, Paraguay. "We call it 'deforestation diesel'," Lovera told IPS.

Oil from African palm trees is considered to be one of the best and cheapest sources of biodiesel and energy companies are investing billions into acquiring or developing oil-palm plantations in developing countries. Vast tracts of forest in Indonesia, Malaysia, Thailand and many other countries have been cleared to grow oil palms. Oil palm has become the world's number one fruit crop, well ahead of bananas.

Biodiesel offers many environmental benefits over diesel from petroleum, including reductions in air pollutants, but the enormous global thirst means millions more hectares could be converted into monocultures of oil palm. Getting accurate numbers on how much forest is being lost is very difficult.

The FAO's State of the World's Forests 2007 released last week reports that globally, net forest loss is 20,000 hectares per day -- equivalent to an area twice the size of Paris. However, that number includes plantation forests, which masks the actual extent of tropical deforestation, about 40,000 hectares (ha) per day, says Matti Palo, a forest economics expert who is affiliated with the Tropical Agricultural Research and Higher Education Center (CATIE) in Costa Rica.

"The half a million ha per year deforestation of Mexico is covered by the increase of forests in the U.S., for example," Palo told IPS.

National governments provide all the statistics, and countries like Canada do not produce anything reliable, he said. Canada has claimed no net change in its forests for 15 years despite being the largest producer of pulp and paper. "Canada has a moral responsibility to tell the rest of the world what kind of changes have taken place there," he said.

Plantation forests are nothing like natural or native forests. More akin to a field of maize, plantation forests are hostile environments to nearly every animal, bird and even insects. Such forests have been shown to have a negative impact on the water cycle because non-native, fast-growing trees use high volumes of water. Pesticides are also commonly used to suppress competing growth from other plants and to prevent disease outbreaks, also impacting water quality.

Plantation forests also offer very few employment opportunities, resulting in a net loss of jobs. "Plantation forests are a tremendous disaster for biodiversity and local people," Lovera said. Even if farmland or savanna are only used for oil palm or other plantations, it often forces the local people off the land and into nearby forests, including national parks, which they clear to grow crops, pasture animals and collect firewood. That has been the pattern with pulp and timber plantation forests in much of the world, says Lovera.

Ethanol is other major biofuel, which is made from maize, sugar cane or other crops. As prices for biofuels climb, more land is cleared to grow the crops. U.S. farmers are switching from soy to maize to meet the ethanol demand. That is having a knock on effect of pushing up soy prices, which is driving the conversion of the Amazon rainforest into soy, she says. Meanwhile rich countries are starting to plant trees to offset their emissions of carbon dioxide, called carbon sequestration. Most of this planting is taking place in the South in the form of plantations, which are just the latest threat to existing forests. "Europe's carbon credit market could be disastrous," Lovera said.

The multi-billion-euro European carbon market does not permit the use of reforestation projects for carbon credits. But there has been a tremendous surge in private companies offering such credits for tree planting projects. Very little of this money goes to small land holders, she says. Plantation forests also contain much less carbon, notes Palo, citing a recent study that showed carbon content of plantation forests in some Asian tropical countries was only 45 percent of that in the respective natural forests. Nor has the world community been able to properly account for the value of the enormous volumes of carbon stored in existing forests.

One recent estimate found that the northern Boreal forest provided 250 billion dollars a year in ecosystem services such as absorbing carbon emissions from the atmosphere and cleaning water. The good news is that deforestation, even in remote areas, is easily stopped. All it takes is access to some low-cost satellite imagery and governments that actually want to slow or halt deforestation. Costa Rica has nearly eliminated deforestation by making it illegal to convert forest into farmland, says Lovera.

Paraguay enacted similar laws in 2004, and then regularly checked satellite images of its forests, sending forestry officials and police to enforce the law where it was being violated. "Deforestation has been reduced by 85 percent in less than two years in the eastern part of the country," Lovera noted. The other part of the solution is to give control over forests to the local people. This community or model forest concept has proved to be sustainable in many parts of the world. India recently passed a bill returning the bulk of its forests back to local communities for management, she said.

However, economic interests pushing deforestation in countries like Brazil and Indonesia are so powerful, there may eventually be little natural forest left. "Governments are beginning to realize that their natural forests have enormous value left standing," Lovera said. "A moratorium or ban on deforestation is the only way to stop this."

Answer 7

I find that when I use E10 fuel, I get about 1 to 1.5 MPG less than with Premium higher octane fuel.
